1 SUSE Manager on IBM z Systems #

1.1 Introduction
1.2 Base System Requirements
1.3 Additional Requirements
1.4 SLES 12 SP3 Installation and the SUSE Manager Extension

1.1 Introduction #

This best practice guide is intended for z/VM administrators responsible for operating the IBM z Systems Mainframe. The goal of this guide is to lead an z/VM administrator trained on normal z Systems operating protocols through the installation of SUSE Manager 3.1 onto an existing mainframe system. The intent of this article is not to cover the variety of hardware configuration profiles available on z Systems but instead to provide a foundational overview of the procedure and requirements necessary for a successful SUSE Manager server deployment.

1.2 Base System Requirements #

The z/VM administrator should acquire and prepare the following resources for a successful SUSE Manager installation. SUSE Manager 3.1 is delivered as an extension. These sections will provide you with the minimum and recommended system requirements for SUSE Manager. The base system for SUSE Manager 3.1 is SLES 12 SP3.

Hardware	Recommended Hardware
IBM Systems	IBM zEnterprise System z196 (z196) IBM zEnterprise System z114 (z114) IBM zEnterprise EC12 (zEC12) IBM zEnterprise EC12 (zEC12) IBM zEnterprise BC12 (zBC12) IBM z13 (z13) LinuxOne Rockhopper LinuxOne Emperor
RAM	Split memory requirements across available RAM, VDISK and swap to suit your environment. On a production system the ratio of physical memory to VDISK will need to be re-evaluated based on the number of clients which will be supported. Minimum 5 GB+ for test server (3GB RAM + 2GB VDISK Swap) Minimum 16 GB+ for base installation Minimum 32 GB+ for a production server
Free Disk Space	Minimum 100 GB for root partition Minimum 50 GB for /var/lib/pgsql Minimum 50 GB per SUSE product + 100 GB per Red Hat product /var/spacewalk
Network Connection	OSA Express Ethernet (including Fast and Gigabit Ethernet) HiperSockets or Guest LAN 10 GBE, VSWITCH RoCE (RDMA over Converged Ethernet) The following interfaces are still included but no longer supported: CTC (or virtual CTC) IP network interface for IUCV

Media Requirements #

SUSE Linux Enterprise 12 SP3 Installation Media for IBM z Systems:
https://www.suse.com/products/server/download/

1.3 Additional Requirements #

There are a few additional resource requirements you will need to prepare before installing the SUSE Manager extension on your system. This section overviews these requirements.

The guest z/VM should be provided with a static IP address and hostname as these cannot be easily changed after initial setup. The hostname should contain less than 8 characters.

For more information on SUSE Manager 3.1 additional requirements see also: https://www.suse.com/documentation/suse-manager-3/book_suma_best_practices/data/mgr_conceptual_overview.html

You are required to calculate sufficient disk storage for SUSE Manager before running yast2 susemanager_setup. The following information will help fulfill these requirements.

Warning: SUSE Manager Default Volume Groups and Disk Space

By default the file system of SUSE Manager including the embedded database and patch directories will reside within the root volume. While adjustments are possible once installation has completed it becomes the administrators responsibility to specify and monitor these adjustments.

If your SUSE Manager runs out of disk space, this can have a severe impact on its database and file structure. Preparing storage requirements in accordance with this section will aid in preventing these harmful effects.

SUSE technical services will be unable to provide support for systems suffering from low disk space conditions as this can have an effect on an entire system and therefore becomes unresolvable. A full recovery is only possible with a previous backup or a new SUSE Manager installation.

Required Storage Devices #

An additional disk is required for database storage. This should be an zFCP or DASD device as these are preferred for use with HYPERPAV. This disk should fulfill the following requirements
At least 50 GB for
```
/var/lib/pgsql
```
Minimum 50 GB per SUSE product + 100 GB per Red Hat product
```
/var/spacewalk
```

1.4 SLES 12 SP3 Installation and the SUSE Manager Extension #

This section covers the installation of SUSE Manager 3.1 as an extension to SLES 12 SP3.

For more information on deploying SLES 12 SP3 on your hardware see: https://www.suse.com/documentation/sles-12/book_sle_deployment/data/cha_zseries.html

During installation of SLES 12 SP3 select SUSE Manager 3 as an extension.

After rebooting you will need to set up the additional storage required for /var/spacewalk and /var/lib/pgsql and swap space using the yast partitioner tool. This step is required before running yast2 susemanager_setup.

After configuring the storage requirements, having executed a yast2 online update and completed a full system reboot, run SUSE Manager setup to finalize the SUSE Manager installation on your z Systems mainframe:

# yast2 susemanager_setup

This completes the installation of SUSE Manager 3.1 on your z Systems. For more information on beginning management with SUSE Manager, review the documentation at https://www.suse.com/documentation/suse-manager-3/.

2.1 Overview #

SUSE Manager 3.1 Proxy is a SUSE Manager add-on that caches software packages on an internal, central server. The proxy caches patch updates from SUSE or custom RPMs generated by third-party organizations. A proxy allows you to use bandwidth more effectively because client systems connect to the proxy for updates, and the SUSE Manager server is no longer required to handle all client requests. The proxy also supports transparent custom package deployment.

SUSE Manager Proxy is an open source (GPLv2) solution that provides the following features:

Cache software packages within a Squid proxy.
Client systems see the SUSE Manager Proxy as a SUSE Manager server instance.
The SUSE Manager Proxy is registered as a client system with the SUSE Manager server.

The primary goal of a SUSE Manager Proxy is to improve SUSE Manager performance by reducing bandwidth requirements and accelerating response time.

2.2 Proxy Installation and Connecting Clients #

2.2.1 Requirements #

The following section provides SUSE Manager 3.1 Proxy requirements.

Supported Client Systems. For supported clients and their requirements, see Book “Getting Started”, Chapter 1 “What is Covered?”, Section 1.7 “Supported Client Systems”.

Hardware Requirements. Hardware requirements highly depend on your usage scenario. When planning proxy environments, consider the amount of data you want to cache on your proxy. If your proxy should be a 1:1 mirror of your SUSE Manager, the same amount of disk space is required. For specific hardware requirements, see the following table.

Hardware	Required
CPU	Multi-core 64-bit CPU (x86_64).
RAM	Minimum 4 GB for a non-production server Minimum 16 GB for a production server
Free Disk Space	Minimum 100 GB for base installation and at least 50 GB for caching per SUSE product and +100 GB per Red Hat product; a resizeable partition strongly recommended.

Hardware

Required

CPU

Multi-core 64-bit CPU (x86_64).

RAM

Minimum 4 GB for a non-production server

Minimum 16 GB for a production server

Free Disk Space

Minimum 100 GB for base installation and at least 50 GB for caching per SUSE product and +100 GB per Red Hat product; a resizeable partition strongly recommended.

Tip: Storage for Proxy Data

SUSE recommends storing the squid proxy caching data on a separate disk formatted with the XFS file system.

SSL Certificate Password. For installing the proxy, you need the SSL certificate password entered during the initial installation of SUSE Manager.

Network Requirements. For additional network requirements, see Book “Getting Started”, Chapter 1 “What is Covered?”, Section 1.8 “Additional Requirements”.

SUSE Customer Center. For using SUSE Manager 3.1 Proxy, you need an account at SUSE Customer Center (SCC) where your purchased products and product subscriptions are registered. Make sure you have the following subscriptions:

One or more subscriptions for SUSE Manager Proxy.
One or more subscriptions for SUSE Manager.
Subscriptions for the products on the client systems you want to register with SUSE Manager via SUSE Manager Proxy.
Subscriptions to client entitlements for the client system you want to register with SUSE Manager via SUSE Manager Proxy.

Network Time Protocol (NTP). The connection to the Web server via Secure Sockets Layer (SSL) requires correct time settings on the server, proxy and clients. For this reason, all systems must use NTP. For more information, see https://www.suse.com/documentation/sles-12/book_sle_admin/data/cha_netz_xntp.html.

Virtual Environments. The following virtual environments are supported:

For running SUSE Manager Proxy in virtual environments, use the following settings for the virtual machine (VM):

At least 1 GB of RAM
Bridged network

2.2.2 Installation and Setup #

The following section will guide you through the installation and setup procedure.

Important: Registering Proxies

SUSE Manager Proxy systems are registered as traditional clients using a bootstrap script. Currently there is no method to register proxy systems using Salt. A SUSE Manager Proxy can serve both Traditional and Salt clients.

Procedure 2.1: Registering the Proxy #

Important

First completly download the channels (SUSE Linux Enterprise 12 SP3) and then create the activation key. Only then you can select the correct child channels.

Create an activation key based on the SUSE Linux Enterprise 12 SP3 base channel. For more information about activation keys, see Book “Getting Started”, Chapter 5 “Registering Clients”, Section 5.2 “Creating Your Keys”.
Figure 2.1: Proxy Activation Key #
Click the Child Channels subtab and select the SUSE Manager 3.1 Proxy child channel with the matching update channel (SUSE Manager Proxy-3.1-Pool and SUSE-Manager-Proxy-3.1-Updates). These child channels are required for providing the proxy packages and updates. As for normal SLES clients, SLES12-SP3-Updates plus SLE-Manager-Tools12-Pool and SLE-Manager-Tools12-Updates are required.
Figure 2.2: Base and Child Proxy Channel #
Modify a bootstrap script for the proxy. Ensure unchecking Bootstrap using Salt, because in this case the proxy must be bootstrapped as a so-called traditional client. For more information about bootstrap scripts, see Book “Getting Started”, Chapter 5 “Registering Clients”, Section 5.4.2 “Modifying the Bootstrap Script”.
Bootstrap the client with the bootstrap script.
You will see a list of channels to which your client is already subscribed to. Select the two unchecked proxy channels which include the SUSE Manager Proxy-3.1-Pool and SUSE-Manager-Proxy-3.1-Updates, then select Change Subscriptions to continue. This will provide the required repositories for the proxy packages from the SUSE Manager server to the client.

A few more steps are still needed:

install the suma_proxy pattern (see Section 2.2.3, “Install the suma_proxy pattern”);
copy the SSL certificate and key from the server (see Section 2.2.4, “Copy Server Certificate and Key”);
run configure-proxy.sh (see Section 2.2.5, “Running configure-proxy.sh”);

You will then be able to register your clients against the proxy using the Web UI or a bootstrap script as if it were a SUSE Manager server. For more information, see Section 2.2.6, “Registering Salt Clients via SUSE Manager Proxy”.

2.2.3 Install the `suma_proxy` pattern #

Make sure the suma_proxy pattern version 2.5.1.3 or later is installed using the following command on the proxy:

root # zypper in -t pattern suma_proxy

The new salt-broker service will be automatically started at the end of the package installation. This service forwards the Salt interactions to the SUSE Manager server.

Note: Proxy Chains

It is possible to arrange Salt proxies in a chain. In such a case, the upstream proxy is named “parent”.

Make sure the proxie's TCP ports 4505 and 4506 are open and that the proxy can reach the SUSE Manager server (or another upstream proxy) on these ports.

2.2.4 Copy Server Certificate and Key #

The proxy will share some SSL information with the SUSE Manager server, so the next step is to copy the certificate and its key from the SUSE Manager server or the upstream proxy.

As root, enter the following commands on the proxy using your SUSE Manager server or chained proxy named as PARENT:

root # cd /root/ssl-build
root # scp root@PARENT:/root/ssl-build/RHN-ORG-PRIVATE-SSL-KEY .
root # scp root@PARENT:/root/ssl-build/RHN-ORG-TRUSTED-SSL-CERT .
root # scp root@PARENT:/root/ssl-build/rhn-ca-openssl.cnf .

Note: Known Limitation

The SUSE Manager Proxy functionality is only supported if the same SSL certificate generated for SUSE Manager Server was used when setting up the Proxy. Using different certificates for Proxies and Server is at the moment not supported.

2.2.5 Running `configure-proxy.sh` #

The configure-proxy.sh script will finalize the setup of your SUSE Manager Proxy.

Now execute the interactive configure-proxy.sh script. Pressing Enter without further input will make the script use the default values provided between brackets []. Here is some information about the requested settings:

SUSE Manager Parent: A SUSE Manager parent can be either another proxy server or a SUSE Manager server.
HTTP Proxy: A HTTP proxy enables your SUSE Manager proxy to access the Web. This is needed if where direct access to the Web is prohibited by a firewall.
Proxy Version to Activate: Normally, the correct value (3.0 or 3.1) should be offered as a default.
Traceback Email: An email address where to report problems.
Use SSL: For safety reasons, press Y.
Do You Want to Import Existing Certificates?: Answer N. This ensures using the new certificates that were copied previously from the SUSE Manager server.
Organization: The next questions are about the characteristics to use for the SSL certificate of the proxy. The organization might be the same organization that was used on the server, unless of course your proxy is not in the same organization as your main server.
Organization Unit: The default value here is the proxy's hostname.
City, State, Country code, Email: Further information attached to the proxy's certificate. Beware the country code must be made of two upper case letters. For further information on country codes, refer to the online list of alpha-2 codes.
Tip: Country Code
As the country code enter the country code set during the SUSE Manager installation. For example, if your proxy is in US and your SUSE Manager in DE, you must enter DE for the proxy.
Cname Aliases (Separated by Space): Use this if your proxy server can be accessed through various DNS CNAME aliases. Otherwise it can be left empty.
CA Password: Enter the password that was used for the certificate of your SUSE Manager server.
Do You Want to Use an Existing SSH Key for Proxying SSH-Push Salt Minions?: Use this option if you want to reuse a SSH key that was used for SSH-Push Salt minions on the server.
Create and Populate Configuration Channel rhn_proxy_config_1000010001?: Accept default Y.
SUSE Manager Username, Password: Use same user name and password as on the SUSE Manager server.
Activate advertising proxy via SLP?: SLP stands for Service Location Protocol.

If parts are missing, such as CA key and public certificate, the script prints commands that you must execute to integrate the needed files. When the mandatory files are copied, re-run configure-proxy.sh. Also restart the script if a HTTP error was met during script execution.

configure-proxy.sh activates services required by SUSE Manager Proxy, such as squid, apache2, salt-broker, and jabberd.

To check the status of the proxy system and its clients, click the proxy system's details page on the Web UI (Systems › Proxy, then the system name). Connection and Proxy subtabs display the respective status information.

2.2.6 Registering Salt Clients via SUSE Manager Proxy #

Proxy servers may now act as a broker and package cache for Salt minions. These minions can be registered with a bootstrap script like the traditional clients, or directly from the Web UI or the command line.

Registering Salt clients via SUSE Manager Proxy from the Web UI is done almost the same way as registering clients directly with the SUSE Manager server. The difference is that you specify the name of the proxy in the Proxy drop-box on Salt › Bootstrapping page.

Figure 2.3: Bootstrapping a Salt Client With a Proxy #

Procedure 2.2: Register a Salt client through a proxy from command line #

Instead of the Web UI, you may use the command line to register a minion through a proxy. To do so, add the proxy FQDN as the master in the minions configuration file located at:
```
/etc/salt/minion
```
or alternatively:
```
/etc/salt/minion.d/name.conf
```
Add the FQDN to the minion file:
```
master: proxy123.example.com
```
Save and restart the salt-minion service with:
```
root # systemctl restart salt-minion
```
On the proxy, accept the new minion key with:
```
root # salt-key -a 'minion'
```
The minion will now connect to the proxy exclusively for Salt operations and normal HTTP package downloads.

2.2.7 Registering Clients via SUSE Manager Proxy with a Script #

Registering clients (either traditional or Salt) via SUSE Manager Proxy with a script is done almost the same way as registering clients directly with the SUSE Manager server. The difference is that you create the bootstrap script on the SUSE Manager Proxy with a command-line tool. The bootstrap script then deploys all necessary information to the clients. The bootstrap script refers some parameters (such as activation keys or GPG keys) that depend on your specific setup.

Create a client activation key on the SUSE Manager server using the Web UI. See Book “Getting Started”, Chapter 5 “Registering Clients”, Section 5.2 “Creating Your Keys”.
On the proxy, execute the mgr-bootstrap command-line tool as root. If needed, use the additional command-line switches to tune your bootstrap script. An important option is --traditional that enables to opt for a traditional client instead of a salt minion.
To view available options type mgr-bootstrap --help from the command line:
```
# mgr-bootstrap --activation-keys=key-string
```
Optionally edit the resulting bootstrap script. Execute the bootstrap script on the clients as described in Book “Getting Started”, Chapter 5 “Registering Clients”, Section 5.4.3 “Connecting Your First Client”.

The clients are registered with the SUSE Manager Proxy specified in the bootstrap script.

2.2.8 Additional Information about Client Registration on Proxies #

Within the Web UI, standard proxy pages will show information about client, no matter whether minions or traditional clients.

A list of clients connected to a proxy can be located under Systems <proxy name> Details Proxy.

A list of chained proxies for a minion can be located under Systems <minion name> Details Connection

If you decide to move any of your clients between proxies or the server you will need to repeat the registration process from scratch.

2.3 Enabling PXE Boot via SUSE Manager Proxy #

2.3.1 Synchronizing Profiles and System Information #

To enable PXE boot via a proxy server, additional software must be installed and configured on both the SUSE Manager server and the SUSE Manager Proxy server.

On the SUSE Manager server install susemanager-tftpsync :
```
# zypper in susemanager-tftpsync
```
On the SUSE Manager Proxy server install susemanager-tftpsync-recv :
```
# zypper in susemanager-tftpsync-recv
```
Run the configure-tftpsync.sh setup script and enter the requested information:
```
# configure-tftpsync.sh
```
It asks for hostname and IP address of the SUSE Manager server and of the proxy itself. Additionally, it asks for the tftpboot directory on the proxy.
On the SUSE Manager server, run configure-tftpsync.sh to configure the upload to the SUSE Manager Proxy server:
```
# configure-tftpsync.sh FQDN_of_Proxy_Server
```
To initiate an initial synchronization on the SUSE Manager Server run:
```
# cobbler sync
```
Also can also be done after each a change within Cobbler that needs to be synchronized immediately. Otherwise Cobbler synchronization will also run automatically when needed. For more information about Cobbler, see Chapter 7, Cobbler.

2.3.2 Configuring DHCP for PXE via SUSE Manager Proxy #

SUSE Manager is using Cobbler to provide provisioning. PXE (tftp) is installed and activated by default. To enable systems to find the PXE boot on the SUSE Manager Proxy server add the following to the DHCP configuration for the zone containing the systems to be provisioned:

next-server: IP_Address_of_SUSE_Manager_Proxy_Server
filename: "pxelinux.0"

2.4 Migrating SUSE Manager 3 Proxy to Version 3.1 #

The recommended order for migrations is to first migrate the server and then the proxies. Note that a SUSE Manager 3 Proxy cooperates just fine with SUSE Manager 3.1.

For the migration of the proxies there are two possible approaches: Existing SUSE Manager proxies may be upgraded to version 3.1 with YaST or zypper migration. Alternatively, the proxies may be replaced by new ones. This section documents both approaches.

Note: Version Information

SUSE Manager 3.1 and SUSE Manager 3.1 Proxy were originally released as a SLES 12 SP2 extension. With the next maintenance update (2017), both will be based on SLES 12 SP3 and support SLE 12 SP3 clients officially. In the following sections and chapters, it is highly recommended to use SLE 12 SP3 instead of SP2.

2.4.1 Replacing a SUSE Manager Proxy #

A SUSE Manager Proxy is dumb in the sense that it does not contain any information about the clients which are connected to it. A SUSE Manager Proxy can therefore be replaced by a new one. Naturally, the replacement proxy must have the same name and IP address as its predecessor.

In order to replace a SUSE Manager Proxy and keeping the clients registered to the proxy leave the old proxy in SUSE Manager. Create a reactivation key for this system and then register the new proxy using the reactivation key. If you do not use the reactivation key, you will need to re-registered all the clients against the new proxy.

Procedure 2.3: Replacing a SUSE Manager Proxy and Keeping the Clients Registered #

Before starting the actual migration procedure, save the data from the old proxy, if needed. Consider copying important data to a central place that can also be accessed by the new server:
- Copy the scripts that are still needed.
- Copy the activation keys from the previous server. Of course, it is always better to re-create the keys.
Shutdown the server.
Install a new SUSE Manager 3.1 Proxy, see Section 2.2, “Proxy Installation and Connecting Clients”.
In the SUSE Manager Web UI select the newly installed SUSE Manager Proxy and delete it from the systems list.
In the Web UI, create a reactivation key for the old proxy system: On the System Details of the old proxy click Reactivation. Then click Generate New Key, and remember it (write it on a piece of paper or copy it to the clipboard). For more information about reactivation keys, see Book “Reference Manual”, Chapter 2 “Systems”, Section 2.3.1.4 “ System Details > Details > Reactivation [Management]”.
After the installation of the new proxy, perform the following actions (if needed):
- Copy the centrally saved data to the new proxy system.
- Install any other needed software.
- If the proxy is also used for autoinstallation, do not forget to setup TFTP synchronization.

Important: Proxy Installation and Client Connections

During the installation of the proxy, clients will not be able to reach the SUSE Manager server. After a SUSE Manager Proxy system has been deleted from the systems list, all clients connected to this proxy will be (incorrectly) listed as directly connected to the SUSE Manager server. After the first successful operation on a client such as execution of a remote command or installation of a package or patch this information will automatically be corrected. This may take a few hours.

2.4.2 Upgrading a SUSE Manager Proxy from 3 to 3.1 #

In most situations upgrading the proxy will be your preferred solution as this retains all cached packages. Selecting this route saves time especially regarding proxies connected to SUSE Manager server via low-bandwith links. This upgrade is similar to a standard client migration.

Warning: Synchronizing Target Channels

Before successfully initializing the product migration, you first must make sure that the migration target channels are completely mirrored. For the upgrade to SUSE Manager 3.1 Proxy, at least the SUSE Linux Enterprise Server 12 SP3 base channel with the SUSE Manager Proxy 3.1 child channel for your architecture is required.

Procedure 2.4: Migrating Proxy to 3.1 #

Direct your browser to the SUSE Manager Web UI where your proxy is registered, and login.
On the Systems › Systems › Proxy page select your proxy client system from the table.
Figure 2.4: SUSE Manager Proxy Details Page #
On the system's detail page (Figure 2.4, “SUSE Manager Proxy Details Page”) select the Software tab, then the SP Migration tab (Figure 2.5, “SP Migration Page”).
Figure 2.5: SP Migration Page #
On Figure 2.5, “SP Migration Page” you will see the installed products listed on your proxy client, and the available target products. Select the wanted Target Products, which include SUSE Linux Enterprise Server 12 SP3 and SUSE Manager Proxy 3.1.
Figure 2.6: SP Migration Target #
Then confirm with Select Channels.
Figure 2.7: SP Migration Channels #
On Figure 2.7, “SP Migration Channels”, Schedule Migration, and then Confirm.

Check the System Status on the system's details when the migration is done.

Figure 2.8: Migrated SUSE Manager Proxy System #

Note: Checking `refresh_pattern` in `/etc/squid/squid.conf`

If you migrate from an early SUSE Manager Proxy 3.0 add the following refresh_pattern to /etc/squid/squid.conf:

# salt minions get the repodata via a different URL
refresh_pattern /rhn/manager/download/.*/repodata/.*$ 0 1% 1440 ignore-no-cache reload-into-ims refresh-ims

Finally consider to schedule a reboot.

2.5 Migrating SUSE Manager 2.1 Proxy to Version 3.1 #

For the migration of SUSE Manager 2.1 Proxies there are two possible approaches—this section documents both approaches:

Existing SUSE Manager proxies may be replaced by newly installed and reconfigured proxies, see Section 2.5.1, “Replacing a SUSE Manager Proxy”. This is the recommended method.
Proxies may be auto-upgraded to version 3.1 by means of YaST auto-installation, see Section 2.5.2, “Upgrading a SUSE Manager Proxy from 2.1 to 3.1”.

Tip: Order of Server and Proxy Migration

The recommended order for migrations is to first migrate the server and then the proxies. A SUSE Manager 2.1 Proxy cooperates just fine with SUSE Manager 3.1.

2.5.1 Replacing a SUSE Manager Proxy #

A SUSE Manager Proxy is dumb in the sense that it does not contain any information about the clients which are connected to it. A SUSE Manager Proxy can therefore be replaced by a new one. The replacement proxy must have the same name and IP address as its predecessor.

Procedure 2.5: Replacing a SUSE Manager Proxy and Keeping the Clients Registered #

Before starting the actual migration procedure, save the important data from the old proxy. Copy the data to a central place that also the new server can access:
- Copy the scripts that are still needed.
- Copy the activation keys from the existing server. Of course, it is always better to re-create the keys.
Shutdown the server.
Install a new SUSE Manager 3.1 Proxy, see Section 2.2, “Proxy Installation and Connecting Clients”.
Important: Proxy Installation and Client Connections
During the installation of the proxy, clients will not be able to reach the SUSE Manager server. After a SUSE Manager Proxy system has been deleted from the systems list, all clients connected to this proxy will be (incorrectly) listed as directly connected to the SUSE Manager server. After the first successful operation on a client such as execution of a remote command or installation of a package or patch this information will automatically be corrected. This may take a few hours.
In the SUSE Manager Web UI select the newly installed SUSE Manager Proxy and delete it from the systems list.
In the Web UI, create a reactivation key for the old proxy system: On the System Details of the old proxy click Reactivation. Then click Generate New Key, and remember it (write it on a piece of paper or copy it to the clipboard). For more information about reactivation keys, see Book “Reference Manual”, Chapter 2 “Systems”, Section 2.3.1.4 “ System Details > Details > Reactivation [Management]”.
After the installation of the new proxy, perform the following actions (if needed):
- Copy the centrally saved data back to the new proxy system.
- Install any other needed software.
- If the proxy is also used for autoinstallation, do not forget to setup TFTP synchronization.

2.5.2 Upgrading a SUSE Manager Proxy from 2.1 to 3.1 #

In other situations upgrading the proxy will be the preferred solution as it retains all cached packages. This route saves time especially regarding proxies connected to a SUSE Manager server via low-bandwith links. This upgrade can be automated by using the YaST auto-installation feature.

Procedure 2.6: Upgrading SUSE Manager Proxy from 2.1 to 3.1 #

Create an auto-installable distribution based on SLES 12 SP3. SUSE Manager 3.1 Proxy is an Add-On for SLES 12 SP3. Refer to the Book “Reference Manual”, Chapter 2 “Systems”, Section 2.12 “Autoinstallation” on creating an auto-installable distribution.
To start the auto-installation of a proxy, some additional packages must be installed that are only available in the SUSE Manager Tools channel. These tools were not available for proxies when in the past the system was shipped as an appliance. To gain access to the required packages for use with proxies, the underlying SLES 11 SP3 channel (SLES11-SP3-SUSE-Manager-Tools) needs to be cloned and assigned to the to-be-upgraded proxies. After these steps have been completed, create an auto-installation profile.

In the following example you will see an auto-install profile. The label Proxy31 is used both for the auto-installable distribution as well as for the auto-install profile. Use the following auto-installation as template and create the auto-installation profile by uploading the edited file:

Ensure all channels referenced in this file are available and fully synced. Replace the label Proxy31 with the correct reference chosen for your auto-installation profile. It is recommended to create a new activation key, for example: 1-sles12sp3 which has the relevant channels assigned; later this key will be used to subscribe the upgraded proxy with the correct channels. The following base channel should be assigned:

SLES12-SP3-Pool

Also include the following child channels:

SLE-Manager-Tools12-Pool
SLE-Manager-Tools12-Updates
SLES12-SP3-Updates
SUSE-Manager-Proxy-3.1-Pool
SUSE-Manager-Proxy-3.1-Updates

In Kernel Options enter the following value:

autoupgrade=1 Y2DEBUG=1

The debug setting is not required but can help investigate problems in case something goes wrong; the autoupgrade parameter is vital! Do not remove it.

Save your changes then click on "Variables" and enter the following value:

registration_key=1-sles12sp3

Specify the name of the key which has all respective channels assigned to it. The auto-install file contains a script named remove_initrd_koan.sh. In this script you should specify the device name of your /boot partition.

Note: remove_initrd_koan.sh

The purpose of this script is to act as a workaround for the following problem: During installation the initrd of the installation media (SLES12SP3) is in use. This initrd is rather large (around 50 MB), so there is not enough space left when the new kernel is being installed. Therefore this script deletes the initial ramdisk file once it has been booted. The partition of your boot partition might differ, so it should be explicitly specified in the autoinstall file.

During auto-installation this script attempts to delete the initial ramdisk file once it has booted. Your boot partition may differ, so ensure it is explicitly specified within the auto-install file.

If this step is bypassed or mixed up (for example: specifying a wrong value) it's fine. During installation of the new kernel, YaST will detect that there is not enough space available and will stop. You may switch to another console (there is a shell running on virtual console 2) and reclaim some disk space by issuing the command:

rm /mnt/boot/initrd_koan

When you have completed this step, switch back to the console where YaST is running (console 7) and click Retry. Installation of the kernel will continue and succeed. The system will reboot, a few automated init scripts will run and the proxy will be upgraded to the SUSE Manager 3.1 based on SLES12SP3 and will be fully functional.

3 Security #

3.1 Setup a Minion to Master Validation Fingerprint

3.1 Setup a Minion to Master Validation Fingerprint #

In highly secure network configurations you may wish to ensure your minions are connecting a specific master. To setup validation from minion to master enter the masters fingerprint within the /etc/salt/minion configuration file. See the following procedure:

On the master enter the following command as root and note the fingerprint:
```
salt-key -F master
```
On your minion, open the minion configuration file located in /etc/salt/minion. Uncomment the following line and enter the masters fingerprint replacing the example fingerprint:
```
master_finger: 'ba:30:65:2a:d6:9e:20:4f:d8:b2:f3:a7:d4:65:11:13'
```
Restart the salt-minion service:
```
# systemctl restart salt-minion
```

For more information on configuring security from a minion see: https://docs.saltstack.com/en/latest/ref/configuration/minion.html

4 SUSE Manager in the Public Cloud #

SUSE Manager Server and SUSE Manager Proxy in the Public Cloud

Abstract#

SUSE Manager delivers best-in-class Linux server management capabilities. For detailed information about the product please refer to the SUSE Manager documentation.

The SUSE Manager Server and SUSE Manager Proxy images published by SUSE in selected Public Cloud environments are provided as Bring Your Own Subscription (BYOS) images. SUSE Manager Server instances need to be registered with the SUSE Customer Center (SCC). Subscriptions of SUSE Manager Proxy instances are handled through their parent SUSE Manager Server. After an instance is launched, SUSE Manager needs to be set up and configured following the procedure in the SUSE Manager documentation.

4.1 Instance Requirements

4.2 Setup

4.2.1 Using Separate Storage Volume

4.3 Registration of Cloned Systems

4.1 Instance Requirements #

Select an instance size that meets the system requirements as documented in the SUSE Manager documentation.

Minimal main memory: >12G
The SUSE Manager setup procedure performs a Forward-confirmed reverse DNS lookup. This must succeed in order for the setup procedure to complete successfully and for SUSE Manager to operate as expected. Therefore it is important that the hostname and IP configuration be performed prior to running the SUSE Manager setup procedure.
SUSE Manager Server and SUSE Manager Proxy instances are expected to run in a network configuration that provides you control over DNS entries and that is shielded from the Internet at large. Within this network configuration DNS (Domain Name Service) resolution must be provided, such that hostname -f returns the FQDN (Full Qualified Domain Name). The DNS resolution is not only important for the SUSE Manager Server procedure but is also important when clients are configured to be managed via SUSE Manager. Configuring DNS is Cloud Framework dependent, please refer to the cloud service provider documentation for detailed instructions.
Minimal free disk space for SUSE Manager 15G.
For Public Cloud instances we recommend that the repositories and the SUSE Manager Server database, and respectively the SUSE Manager Proxy squid cache, be located on an external virtual disk. The details for this setup are provided in Section 4.2.1, “Using Separate Storage Volume”.
Storing the database and the repositories on an external virtual disk ensures that the data is not lost should the instance need to be terminated for some reason.

Please ensure that the selected instance type matches the requirements listed above. Although we recommend that the database and the repositories are stored on a separate device it is still recommended to set the root volume size of the instance to 20G.

4.2 Setup #

Run an instance of the SUSE Manager Server or SUSE Manager Proxy image as published by SUSE.
The images are identifiable by the suse, manager, server or proxy, and byos keywords in each public cloud environment.
The SUSE Manager instance must run in a network access restricted environment such as the private subnet of a VPC or with an appropriate firewall setting such that it can only be accessed by machines in the IP ranges you use. A generally accessible SUSE Manager instance violates the terms of the SUSE Manager EULA. Access to the web interface of SUSE Manager requires https.
Setup the hostname as follows:
SUSE Manager requires a stable and reliable hostname and does not take kindly to hostname changes. All commands provided need to be executed as the root user.
1. Disable hostname setup in the dhcp configuration file: /etc/sysconfig/network/dhcp
```
DHCLIENT_SET_HOSTNAME="no"
```
2. Set the hostname to a name of your choice. Please note it is important to provide the system name and not the fully qualified hostname to the hostnamectl command.
  It is expected that the Fully Qualified Domain Name (FQDN) is set by the cloud framework; for example if cloud_instance.cloud.net is the fully qualified name than cloud_instance is the system name and cloud.net is the domain name.
  In the following example we will change the system name to suma
```
$ hostnamectl set-hostname suma
```
  The fully qualified hostname is now locally set to suma.cloud.net. Once the hostname is set locally a DNS entry needs to be created in your network environment such that domain name resolution works properly.
  Alternatively to force proper resolution of the name on the SUSE Manager system you may alter the /etc/hosts file as follows:
```
$ echo "${local_address} suma.cloud.net suma" >> /etc/hosts
```
  The current value for the local_address, can be obtained from the public cloud Web console or from within a terminal session as follows:
  - Obtain local ip address from within Amazon EC2 instance
    $ ec2metadata --local-ipv4
  - Obtain local ip address from within Google Compute Engine instance
    $ gcemetadata --query instance --network-interfaces --ip
  - Obtain local ip address from within Microsoft Azure instance
    $ azuremetadata --internal-ip
  Note that forcing the DNS resolution to work via modification of the /etc/hosts file will allow the yast2 susemanager_setup procedure to work. However, if DNS resolution is not properly configured this also implies that any client that is to be managed via this SUSE Manager instance must also receive the same modification to /etc/hosts.
  One more aspect of hostname resolution is the /etc/resolv.conf file. Depending on the order of your setup, i.e. if you started the SUSE Manager instance prior to setting up DNS services the file may not contain the appropriate search directive. Double check that the proper search directive exists in /etc/resolv.conf. In our example the directive would be search cloud.net. If the directive is missing add it to the file.
  Reference information for the DNS record update is provided below.
3. For an update of the DNS records for the instance within the DNS service of your network environment, refer to the cloud service provider documentation for detailed instructions:
Configure SUSE Manager
1. If you run a SUSE Manager Server instance run YaST as shown below after the instance is launched, the external storage is attached and prepared according to Section 4.2.1, “Using Separate Storage Volume”, and the DNS resolution is set up as described earlier.
```
$ /sbin/yast2 susemanager_setup
```
  Note that the setup of SUSE Manager from this point forward does not differ from the documentation in the SUSE Manager Guide.
  The SUSE Manager setup procedure in YaST is designed as a one pass process with no rollback or cleanup capability. Therefore, if the setup procedure is interrupted or ends with an error, it is not recommended to attempt a recovery as a reapate of the setup process or attempts to manually "fix" the configuration are most likely to fail and result in a broken SUSE Manager installation. In case of any errors we recommend to start a new instance in order to run a fresh setup procedure on a clean system.
  If you are prompted with a message that there is not enough space available for the setup of SUSE Manager verify that your root volume is at least 20GB and double check that the instructions in Section 4.2.1, “Using Separate Storage Volume” had the desired effects.
  SUSE Manager Server for the Public Cloud comes with a bootstrap data module pre-installed that contains optimized package lists for bootstrapping instances started from SUSE Linux Enterprise images published by SUSE. If you intend to register such an instance, make sure when creating the bootstrap repository you run the mgr-create-bootstrap-repo script as follows:
```
$ mgr-create-bootstrap-repo --datamodule=mgr_pubcloud_bootstrap_data -c SLE-12-SP1-x86_64
```
  The above example creates a bootstrap repository suitable for SUSE Linux Enterprise Server 12 SP1 instances. See Creating the SUSE Manger Tools Repository for more information on bootstrapping.
  Prior to registering instances started from on demand images remove the following packages from the instance to be registered:
  1. cloud-regionsrv-client
  2. For Amazon EC2
    regionServiceClientConfigEC2
    regionServiceCertsEC2
  3. For Google Compute Engine
    cloud-regionsrv-client-plugin-gce
    regionServiceClientConfigGCE
    regionServiceCertsGCE
  4. For Microsoft Azure
    regionServiceClientConfigAzure
    regionServiceCertsAzure
  If these packages are not removed it is possible to create interference between the repositories provided by SUSE Manager and the repositories provided by the SUSE operated update infrastructure.
  Additionally remove the line from the /etc/hosts file that contains the susecloud.net reference.
2. If you run a SUSE Manager Proxy instance
  Launch the instance, optionally with external storage configured. If you use external storage (recommended), prepare it according to Section 4.2.1, “Using Separate Storage Volume”. It is recommended but not required to prepare the storage before configuring SUSE Manager proxy, as the suma-storage script will migrate any existing cached data to the external storage. After preparing the instance, register the system with the parent SUSE Manager, which could be a SUSE Manager Server or another SUSE Manager Proxy. See the SUSE Manager Proxy Setup guide for details. Once registered, run
```
$ /usr/sbin/configure-proxy.sh
```
  to configure your SUSE Manager Proxy instance.

After the completion of the configuration step, SUSE Manager should be functional and running. For SUSE Manager Server, the setup process created an administrator user with following user name:

User name: admin

Table 4.1: Account credentials for admin user #

Amazon EC2	Google Compute Engine	Microsoft Azure
Instance-ID	Instance-ID	Instance-Name-suma

The current value for the Instance-ID or Instance-Name in case of the Azure Cloud, can be obtained from the public cloud Web console or from within a terminal session as follows:

Obtain instance id from within Amazon EC2 instance
```
$ ec2metadata --instance-id
```
Obtain instance id from within Google Compute Engine instance
```
$ gcemetadata --query instance --id
```
Obtain instance name from within Microsoft Azure instance
```
$ azuremetadata --instance-name
```

After logging in through the SUSE Manager Server Web UI, change the default password.

SUSE Manager Proxy does not have administration Web interface itself. It can be managed through its parent SUSE Manager Server.

4.2.1 Using Separate Storage Volume #

We recommend that the repositories and the database for SUSE Manager be stored on a virtual storage device. This best practice will avoid data loss in cases where the SUSE Manager instance may need to be terminated. These steps must be performed prior to running the YaST SUSE Manager setup procedure.

Provision a disk device in the public cloud environment, refer to the cloud service provider documentation for detailed instructions. The size of the disk is dependent on the number of distributions and channels you intend to manage with SUSE Manager. For sizing information refer to SUSE Manager sizing examples. A rule of thumb is 25 GB per distribution per channel.
Once attached the device appears as Unix device node in your instance. For the following command to work this device node name is required. In many cases the attached storage appears as /dev/sdb. In order to check which disk devices exists on your system, call the following command:
```
$ hwinfo --disk | grep -E "Device File:"
```
With the device name at hand the process of re-linking the directories in the filesystem SUSE Manager uses to store data is handled by the suma-storage script. In the following example we use /dev/sdb as the device name.
```
$ /usr/bin/suma-storage /dev/sdb
```
After the call all database and repository files used by SUSE Manager Server are moved to the newly created xfs based storage. In case your instance is a SUSE Manager Proxy, the script will move the Squid cache, which caches the software packages, to the newly created storage. The xfs partition is mounted below the path /manager_storage.
Create an entry in /etc/fstab (optional)
Different cloud frameworks treat the attachment of external storage devices differently at instance boot time. Please refer to the cloud environment documentation for guidance about the fstab entry.
If your cloud framework recommends to add an fstab entry, add the following line to the /etc/fstab file.
```
/dev/sdb1 /manager_storage xfs defaults 1 1
```

4.3 Registration of Cloned Systems #

SUSE Manager treats systems (instances) with the same system ID as one. This implies that one instance will mask another if the instances have the same system ID. This situation occurs by launching multiple instances from the same image or when an image has been created from a running instance. Thus prior to registering a new instance complete step 5.1 or 5.2, depending on the distribution on the following wiki.

5 Optimization and Scalability #

5.1 Optimizing Apache and Tomcat

5.1.1 Apache's httpd MaxClients Parameter
5.1.2 Tomcat's maxThreads Parameter

5.2 Big Scale Deployment (1000 Minions or More)

5.2.1 General Recommendations
5.2.2 Tuning Proposals

5.1 Optimizing Apache and Tomcat #

Warning: Altering Apache and Tomcat Parameters

Apache and Tomcat Parameters should only be modified with support or consulting as these parameters can have severe and catastrophic performance impacts on your server when improperly adjusted. SUSE will not be able to provide support for catastrophic failure when these advanced parameters are modified without consultation. Tuning values for Apache httpd and Tomcat requires that you align these parameters with your server hardware. Furthermore testing of these altered values should be performed within a test environment.

5.1.1 Apache's httpd MaxClients Parameter #

The MaxClients setting determines the number of Apache httpd processes, and thus limits the number of client connections that can be made at the same time (SUSE Manager uses the pre-fork MultiProcessing Modules). The default value for MaxClients in SUSE Manager is 150. If you need to set the MaxClients value greater than 150, Apache httpd's ServerLimit setting and Tomcat's maxThreads must also be increased accordingly (see below).

Warning

The Apache httpd MaxClients parameter must always be less or equal than Tomcat's maxThreads parameter!

If the MaxClients value is reached while the software is running, new client connections will be queued and forced to wait, this may result in timeouts. You can check the Apache httpd's error.log for details:

[error] Server reached MaxClients setting, consider increasing the MaxClients setting

The default MaxClients parameter can be overridden on SUSE Manager by editing the server-tuning.conf file located at /etc/apache2/.

Example server-tuning.conf file:

# prefork MPM
   <IfModule prefork.c>
           # number of server processes to start
           # http://httpd.apache.org/docs/2.2/mod/mpm_common.html#startservers
           StartServers         5
           # minimum number of server processes which are kept spare
           # http://httpd.apache.org/docs/2.2/mod/prefork.html#minspareservers
           MinSpareServers      5
           # maximum number of server processes which are kept spare
           # http://httpd.apache.org/docs/2.2/mod/prefork.html#maxspareservers
           MaxSpareServers     10
           # highest possible MaxClients setting for the lifetime of the Apache process.
           # http://httpd.apache.org/docs/2.2/mod/mpm_common.html#serverlimit
           ServerLimit        150
           # maximum number of server processes allowed to start
           # http://httpd.apache.org/docs/2.2/mod/mpm_common.html#maxclients
           MaxClients         150
           # maximum number of requests a server process serves
           # http://httpd.apache.org/docs/2.2/mod/mpm_common.html#maxrequestsperchild
           MaxRequestsPerChild  10000
   </IfModule>

5.1.2 Tomcat's maxThreads Parameter #

Tomcat's maxThreads represents the maximum number of request processing threads that it will create. This value determines the maximum number of simultaneous requests that it is able to handle. All HTTP requests to the SUSE Manager server (from clients, browsers, XMLRPC API scripts, etc.) are handled by Apache httpd, and some of them are routed to Tomcat for further processing. It is thus important that Tomcat is able to serve the same amount of simultaneous requests that Apache httpd is able to serve in the worst case. The default value for SUSE Manager is 200 and should always be equal or greater than Apache httpd's MaxClients. The maxThreads value is located within the server.xml file located at /etc/tomcat/.

Example relevant lines in server.xml:

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" URIEncoding="UTF-8" address="127.0.0.1" maxThreads="200" connectionTimeout="20000"/>
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" URIEncoding="UTF-8" address="::1" maxThreads="200" connectionTimeout="20000"/>

Note: Tuning Notes

When configuring Apache httpd's MaxClients and Tomcat's maxThreads parameters you should also take into consideration that each HTTP connection will need one or more database connections. If the RDBMS is not able to serve an adequate amount of connections, issues will arise. See the following equation for a rough calculation of the needed amount of database connections:

((3 * java_max) +  apache_max + 60)

Where:

3 is the number of Java processes the server runs with pooled connections (Tomcat, Taskomatic and Search)
java_max is the maximum number of connections per Java pool (20 by default, changeable in /etc/rhn/rhn.conf via the hibernate.c3p0.max_size parameter)
apache_max is Apache httpd's MaxClients
60 is the maximum expected number of extra connections for local processes and other uses

5.2 Big Scale Deployment (1000 Minions or More) #

In the following sections find considerations about a big scale deployment. In this context, a big scale compromises 1000 minions or more.

5.2.1 General Recommendations #

SUSE recommends the following in a big scale SUSE Manager deployment:

SUSE Manager servers should have at least 8 recent x86 cores, 32 GiB of RAM, and, most important, fast I/O devices such as at least an SSD (2 SSDs in RAID-0 are strongly recommended).
Proxies with many minions (hundreds) should have at least 2 recent x86 cores and 16 GiB of RAM.
Use one SUSE Manager Proxy per 500-1000 clients. Keep into account that download time depends on network capacity. Here is a rough example calculation with physical link speed of 1 GB/s:
```
 400 Megabytes  *        3000       /      119 Megabyte/s        / 60
= 169 Minutes
```
This is:
```
Size of updates * Number of minions / Theoretical download speed / 60
```
Depending on hardware you can accept hundreds of minion keys.
Plan time for onboarding minions—at least one hour per 1000 minions.
It is not recommended onboarding more than approx. 1000 minions directly to the SUSE Manager server—proxies should be used instead. This is because every minion can use up to 3 TCP connections simultaneously, and too many TCP connections can cause performance issues.
If the following error appears in output of dmesg, you probably have an excessive number of minions attached to a single SUSE Manager server or proxy for the ARP cache to contain all of their addresses:
```
kernel: neighbour table overflow
```
In that case, increase the ARP cache values via sysctl, for example, by adding the following lines to /etc/sysctl.conf:
```
net.ipv4.neigh.default.gc_thresh1 = 4096
net.ipv4.neigh.default.gc_thresh2 = 8192
net.ipv4.neigh.default.gc_thresh3 = 16384
net.ipv4.neigh.default.gc_interval = 60
net.ipv4.neigh.default.gc_stale_time = 120
```

Tip: Start Small and Scale Up

Always start small and scale up gradually. Keep the server monitored in order to identify possible issues early.

5.2.2 Tuning Proposals #

SUSE proposes the following tuning settingsin a big scale SUSE Manager deployment:

Increase Tomcat memory to face a long queue of Salt return results. Items in the Salt return queue might accumulate in a short time: Set 8 GiB instead of the current default 1 GiB.
Several RHN parameters should be changed from their defaults:
- The number of Taskomatic workers should be increased, and thus parallelizing work on a high number of separate jobs (onboarding, staging).
- Quartz should check for runnable jobs more frequently to reduce latency (onboarding, staging, Action execution).
- Tomcat's Salt return result workers should be increased, and thus parallelizing work on a high number of Salt return results (patching).
- The number of PostgreSQL connections available to Java applications (Tomcat, Taskomatic) should increase accordingly. Otherwise extra workers will starve waiting for a connection.
- Salt's presence ping timeouts should be increased because responses might come back later than the defaults.
Salt master worker threads should be increased to 100 from 15, and thus parallelizing more requests (otherwise Tomcat and Taskomatic workers will starve waiting for the API to do something).
Increasing the number of Salt master worker threads more requires more RAM and does not bring benefits. Apache maximum request time should be increased.

6.1 Introduction #

This chapter provides guidance on the setup of an Icinga server using SLES12 SP2. More information may be found within the Official Icinga documentation: http://docs.icinga.org/latest/en/

6.2 Installation and Basic Configuration #

Icinga packages are found in the SLE-Manager-Tools12-Updates x86_64.

Tip: Icinga Installation Location

Do not install Icinga on the SUSE Manager server. Install Icinga on a stand-alone SLE client.

Procedure 6.1: Installation and Basic Configuration #

Register the monitoring server client with SUSE Manager and add the SUSE Manager client and update channels. For both SLES12 and SLES12 SP2 these channels are included by default.

zypper in icinga icinga-idoutils-pgsql postgresql postgresql94-server \
monitoring-plugins-all apache2

Edit the /etc/icinga/objects/contacts.cfg file and add the email address which you will use for reciving alerts.

define contact {
  contact_name      icingaadmin          ; Short name of user
  use               generic-contact      ; Inherit default values
  alias             Icinga Admin         ; Full name of user
  email             icinga@localhost     ; <<*** CHANGE THIS TO YOUR EMAIL ADDRESS ***
}

Enable postgres on boot and start the database:

systemctl enable postgresql.service
systemctl start postgresql.service

Create the database and user for Icinga:

#su - postgres
 
 >psql
 postgres=# ALTER USER postgres WITH PASSWORD '<newpassword>';
 postgres=# CREATE USER icinga;
 postgres=# ALTER USER icinga WITH PASSWORD 'icinga';
 postgres=# CREATE DATABASE icinga;
 postgres=# GRANT ALL ON DATABASE icinga TO icinga;
 postgres=# \q
 exit

Adjust client authentication rights located in /var/lib/pgsql/data/pg_hba.conf to match the following:

# TYPE  DATABASE        USER            ADDRESS                 METHOD
local   icinga         icinga                                  trust
local   all            postgres                                ident

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local   replication     postgres                                peer
#host    replication     postgres        127.0.0.1/32            ident
#host    replication     postgres        ::1/128                 ident

Important: Placement of Authentication Settings

Ensure the local entries for icinga authentication settings are placed above all other local entries or you will get an error when configuring the database schema. The entries in pg_hba.conf are read from top to bottom.

Reload the Postgres service:
```
systemctl reload postgresql.service
```
Configure the database schema by running the following command in: /usr/share/doc/packages/icinga-idoutils-pgsql/pgsql/:
```
psql -U icinga -d icinga < pgsql.sql
```
Edit the following lines in /etc/icinga/ido2db.cfg to switch from the default setting of mysql to postgres:
```
vi /etc/icinga/ido2db.cfg

 db_servertype=pgsql
 db_port=5432
```
Important: Open Firewall Port
Allow port 5432 through your firewall or you will not be able to access the WebGUI.
Create an icinga admin account for logging into the web interface:
```
htpasswd -c /etc/icinga/htpasswd.users icingaadmin
```

Enable and start all required services:

# systemctl enable icinga.service
# systemctl start icinga.service
# systemctl enable ido2db.service
# systemctl start ido2db.service
# systemctl enable apache2.service
# systemctl start apache2.service

This concludes setup and initial configuration of Icinga.

6.3 Icinga and NRPE Quickstart #

The following sections provides an overview on monitoring your SUSE Manager server using Icinga. You will add SUSE Manager as a host to Icinga and use a nagios script/plugin to monitor running services via NRPE (Nagios Remote Plugin Executor). This section does not attempt to cover all monitoring solutions Icinga has to offer but should help you get started.

Procedure 6.2: Adding SUSE Manager to Icinga for Monitoring #

On your SUSE Manager server install the required packages:

zypper install nagios-nrpe susemanager-nagios-plugin insserv nrpe monitoring-plugins-nrpe

Modify the NRPE configuration file located at:
```
/etc/nrpe.cfg
```
Edit/add the following lines:
```
server_port=5666
nrpe_user=nagios
nrpe_group=nagios
allowed_hosts=Icinga.example.com
dont_blame_nrpe=1
command[check_systemd.sh]=/usr/lib/nagios/plugins/check_systemd.sh $ARG1$
```
Variable definitions:
server_port
The variable server_port defines the port nrpe will listen on. The default port is 5666. This port must be opened in your firewall.
nrpe_user
The variables nrpe_user and nrpe_group control the user and group IDs that nrpe will run under. SUSE Manager probes need access to the database, therefore nrpe requires access to database credentials stored in /etc/rhn/rhn.conf. There are multiple ways to achieve this. You may add the user nagios to the group www (this is already done for other IDs such as tomcat); alternatively you can simply have nrpe run with the effective group ID www in /etc/rhn/rhn.conf.
allowed_hosts
The variable allowed_hosts defines which hosts nrpe will accept connections from. Enter the FQDN or IP address of your Icinga server here.
dont_blame_nrpe
The use of variable dont_blame_nrpe is unavoidable in this example. nrpe commands by default will not allow arguments being passed due to security reasons. However, in this example you should pass the name of the host you want information on to nrpe as an argument. This action is only possible when setting the variable to 1.
command[check_systemd.sh]
You need to define the command(s) that nrpe can run on SUSE Manager. To add a new nrpe command specify a command call by adding command followed by square brackets containing the actual nagios/icinga plugin name. Next define the location of the script to be called on your SUSE Manager server. Finally the variable $ARG1$ will be replaced by the actual host the Icinga server would like information about. In the example above, the command is named check_systemd.sh. You can specify any name you like but keep in mind the command name is the actual script stored in /usr/lib/nagios/plugins/ on your SUSE Manager server. This name must also match your probe definition on the Icinga server. This will be described in greater detail later in the chapter. The check_systemd.sh script/plugin will also be provided in a later section.
One your configuration is complete load the new nrpe configuration with:
```
# systemctl start nrpe
```

This concludes setup of nrpe.

6.3.1 Adding a Host to Icinga #

To add a new host to Icinga create a host.cfg file for each host in /etc/icinga/conf.d/. For example susemanager.cfg:

define host {
  host_name           susemanager
  alias               SUSE Manager
  address             192.168.1.1
  check_period        24x7
  check_interval      1
  retry_interval      1
  max_check_attempts  10  
  check_command       check-host-alive
}

Note

Place the host IP address you want to add to Icinga on the Address line.

After adding a new host restart Icinga and load the new configuation:

# systemctl restart icinga

6.3.2 Adding Services #

To add services for monitoring on a specific host define them by adding a service definition to your host.cfg file located in /etc/icinga/conf.d. For example you can monitor if a systems SSH service is running with the following service definition.

define service {
  host_name           susemanager
  use                 generic-service
  service_description SSH
  check_command       check_ssh
  check_interval      60
}

After adding any new services restart Icinga to load the new configuration:

# systemctl restart icinga

6.3.3 Creating Hostgroups #

You can create hostgroups to simplify and visualize hosts logically. Create a hostgroups.cfg file located in /etc/icinga/conf.d/ and add the following lines:

define hostgroup {
  hostgroup_name  ssh_group
  alias           ssh group
  members         susemanager,mars,jupiter,pluto,examplehost4
}

The members variable should contain the host_name from within each host.cfg file you created to represent your hosts. Every time you add an additional host by creating a host.cfg ensure you add the host_name to the members list of included hosts if you want it to be included within a logical hostgroup.

After adding hosts to a hostgroup restart Icinga to load the new configuration:

# systemctl restart icinga

6.3.4 Creating Servicegroups #

You can create logical groupings of services as well. For example if you would like to create a group of essential SUSE Manager services which are running define them within a servicegroups.cfg file placed in /etc/icinga/conf.d/

#Servicegroup 1
define servicegroup {
  servicegroup_name     SUSE Manager Essential Services
  alias                 Essential Services
}

#Servicegroup 2
define servicegroup {
  servicegroup_name     Client Patch Status
  alias                 SUSE Manager 3 Client Patch Status
}

Within each hosts host.cfg file add a service to a servicegroup with the following variable:

define service {
  use                 generic-service
  service_description SSH
  check_command       check_ssh
  check_interval      60
  servicegroups       SUSE Manager Essential Services
}

All services that include the servicegroups variable and the name of the servicegroup will be added to the specified servicegroup. After adding services to a servicegroup restart Icinga to load the new configuation:

# systemctl restart icinga

6.4 Monitoring Systemd Services #

The following section provides information on monitoring uptime of critical SUSE Manager services.

Procedure 6.3: Monitoring Running Systemd Services #

Create a new plugin file called check_systemd.sh in /usr/lib/nagios/plugins/ on your SUSE Manager server:
```
# vi /usr/lib/nagios/plugins/ check_systemd.sh
```

For this example you will use an opensource community script to monitor Systemd services. You may also wish to write your own.

PLUGINDIR=$(dirname $0)
. $PLUGINDIR/utils.sh


if [ $# -ne 1 ]; then
    echo "Usage: ${0##*/} <service name>" >&2
    exit $STATE_UNKNOWN
fi

service=$1

status=$(systemctl is-enabled $service 2>/dev/null)
r=$?
if [ -z "$status" ]; then
    echo "ERROR: service $service doesn't exist"

if [ $? -ne 0 ]; then
    echo "ERROR: service $service is not running"
    exit $STATE_CRITICAL
fi

echo "OK: service $service is running"
exit $STATE_OK

A current version of this script can be found at: https://github.com/melmorabity/nagios-plugin-systemd-service/blob/master/check_systemd_service.sh

Warning: Non-supported 3rd Party Plugin

The script used in this example is an external script and is not supported by SUSE. Always check to ensure scripts are not modified or contain malicous code before using them on production machines.

Make the script executable:
```
chmod 755 check_systemd.sh
```
On your SUSE manager server add the following line to the nrpe.cfg located at /etc/nrpe.cfg:
```
# SUSE Manager Service Checks
command[check_systemd.sh]=/usr/lib/nagios/plugins/check_systemd.sh $ARG1$
```
This will allow the Icinga server to call the plugin via nrpe on SUSE Manager.
Provide proper permissions by adding the script to the sudoers file:
```
# visudo
```
```
nagios  ALL=(ALL)       NOPASSWD:/usr/lib/nagios/plugins/check_systemd.sh
Defaults:nagios !requiretty
```
You can also add permissions to the entire plugin directory instead of allowing permissions for individual scripts:
```
nagios  ALL=(ALL)       NOPASSWD:/usr/lib/nagios/plugins/
```

On your Icinga server define the following command within /etc/icinga/objects/commands.cfg:

define command{
        command_name   check-systemd-service
        command_line   /usr/lib/nagios/plugins/check_nrpe -H $HOSTADDRESS$ -c check_systemd.sh -a $ARG1$
}

Now you will add the following critical services to be montitored to your SUSE Manager host file:

auditlog-keeper.service
jabberd.service
spacewalk-wait-for-jabberd.service
tomcat.service
spacewalk-wait-for-tomcat.service
salt-master.service
salt-api.service
spacewalk-wait-for-salt.service
apache2.service
osa-dispatcher.service
rhn-search.service
cobblerd.service
taskomatic.service
spacewalk-wait-for-taskomatic.service

On your Icinga server add the following service blocks to your SUSE Manager host file susemanager.cfg file located in /etc/icinga/conf.d/(This configuration file was created in the previous section Adding a Host to Icinga)

       check_command          check-systemd-service!spacewalk-wait-for-taskomatic.service
}

Each of these service blocks will be passed as the check-systemd-service!$ARG1$ variable to SUSE manager server via nrpe. You probably noticed the servicegroups parameter was also included. This adds each service to a servicegroup and has been defined in a servicesgroups.cfg file located in /etc/icinga/conf.d/:

define servicegroup{
       servicegroup_name     SUSE Manager Essential Services
       alias                 Essential Services
}

Restart Icinga:
```
systemctl restart icinga
```

6.5 Using the check_suma_patches Plugin #

You can use the check_suma_patches plugin to check if any machines connected to SUSE Manager as clients require a patch or an update. The following procedure will guide you through the setup of the check_suma_patches plugin.

Procedure 6.4: Setup check_suma_patches #

On your SUSE Manager server open /etc/nrpe.cfg and add the following lines:

# SUSE Manager check_patches
command[check_suma_patches]=sudo /usr/lib/nagios/plugins/check_suma_patches $ARG1$

On your Icinga server open /etc/icinga/objects/commands.cfg and define the following command:

define command{
        command_name    check_suma
        command_line    /usr/lib/nagios/plugins/check_nrpe -H 192.168.1.1 -c $ARG1$ -a $HOSTNAME$
}

On your Icinga server open any of your SUSE Manager client host configration files lcoated at /etc/icinga/conf.d/clients.cfg and add the following service definition:

define service{
        use                             generic-service
        host_name                       client-hostname
        service_description             Available Patches for client-host_name 
        servicegroups                   Client Patch Status
        check_command                   check_suma!check_suma_patches
}

In the above service definition notice that this host is included in the servicegroup labeled Client Patch Status. Add the following servicegroup definition to /etc/icinga/conf.d/servicegroups.cfg to create a servicegroup:
```
define servicegroup {
       servicegroup_name     Client Patch Status
       alias                 SUSE Manager 3 Client Patch Status
}
```
- OK:System is up to date
- Warning: At least one patch or package update is available
- Critical:At least one security/critical update is available
- Unspecified:The host cannot be found in the SUSE Manager database or the host name is not unique

This concludes setup of the check_suma_patches plugin.

6.6 Using the check_suma_lastevent Plugin #

You can use the check_suma_lastevent plugin to display the last action executed on any host.

The following procedure will guide you through the setup of the check_suma_patches plugin.

Procedure 6.5: Setup check_suma_lastevent #

On your SUSE Manager server open /etc/nrpe.cfg and add the following lines:

# Check SUSE Manager Hosts last events
command[check_events]=sudo /usr/lib/nagios/plugins/check_suma_lastevent $ARG1$

On your Icina server open /etc/icinga/objects/commands.cfg and add the following lines:

define command{
        command_name    check_events
        command_line    /usr/lib/nagios/plugins/check_nrpe -H manager.suse.de -c $ARG1$ -a $HOSTNAME$
}

On your Icinga server add the following line to a host.cfg service definition:

define service{
        use                             generic-service
        host_name                       hostname
        service_description             Last Events
        check_command                   check_events!check_suma_lastevent
}

Status will be reported as follows:
- OK:Last action completed successfully
- Warning: Action is currently in progress
- Critical:Last action failed
- Unspecified:The host cannot be found in the SUSE Manager database or the host name is not unique

This concludes setup of the check_suma_lastevent plugin.

7.7 Building ISOs with Cobbler

SUSE Manager features the Cobbler server that allows administrators to centralize their system installation and provisioning infrastructure. Cobbler is an installation server that provides various methods of performing unattended system installations, whether it be server, workstation, or guest systems in a full or para-virtualized setup.

Cobbler offers several tools to assist in pre-installation guidance, automated installation file management, installation environment management, and more. This section explains supported features of Cobbler, which include:

installation environment analysis using the cobbler check command,
multi-site installation server configuration with cobbler replicate,
virtual machine guest installation automation with the koan client-side tool,
building installation ISOs with PXE-like menus using the cobbler buildiso command for SUSE Manager systems with x86_64 architecture.

For more detailed upstream documentation on Cobbler, see http://cobbler.github.io/manuals/.

Important: Supported Cobbler Functions

SUSE only support those Cobbler functions that are either listed within our formal documentation or available via the Web Interface and API.

7.1 Cobbler Requirements #

To use Cobbler as a PXE boot server, follow these guidelines:

For system installation with PXE, you must have a TFTP server installed and configured. By default, SUSE Manager installs such a TFTP server.
To PXE boot systems for installation, you must either set up a DHCP server for Cobbler PXE booting or have access to your network's DHCP server. Edit /etc/dhcp.conf to change next-server to the hostname or IP address of your Cobbler server.

Important: Correct Hostname Configuration

When onboarding bare metal systems using the pxe-default-image, it's important to ensure all systems to be on-board have unique hostnames. Otherwise, if you later assign a provisioning profile to it, the new configuration file will overwrite the configuration settings for any system with the duplicate hostname. Cobbler uses hostnames as a unique key for each system.

7.1.1 Configuring Cobbler with /etc/cobbler/settings #

Cobbler configuration is mainly done in the /etc/cobbler/settings file. With the default settings unchanged, Cobbler runs as intended. All configurable settings are explained in detail in the /etc/cobbler/settings file with regard to how they affect functionality of Cobbler and whether it is recommended for users to adjust values to their environment.

Note: Supported Languages

If SUSE Manager complains about language 'en' was not found within the list of supported languages available at /usr/share/YaST2/data/languages, remove the lang in /etc/cobbler/settings or add a proper value such as en_US.

For background info, see https://www.suse.com/support/kb/doc?id=7018334.

7.1.2 Cobbler and DHCP #

Cobbler supports bare-metal automated installation of systems configured to perform network boots using a PXE boot server. To properly implement a Cobbler installation server, administrators need to either have administrative access to the network's DHCP server or set up DHCP on the Cobbler server itself.

7.1.2.1 Configuring an Existing DHCP Server #

If you have a DHCP server deployed on another system in the network, you will need administrative access to the DHCP server to edit the DHCP configuration file so that it points to the Cobbler server and PXE boot image.

As root on the DHCP server, edit the /etc/dhcpd.conf file and append a new class with options for performing PXE boot installation. For example:

allow booting;
allow bootp; 1
class "PXE" 2 {
match if substring(option vendor-class-identifier, 0, 9) = "PXEClient"; 3
next-server 192.168.2.1; 4
filename "pxelinux.0"; 5
}

Step by step explanation:

1	Enable network booting with the `bootp` protocol.
2	Create a class called `PXE`.
3	A system configured to have PXE first in its boot priority identifies itself as `PXEClient`.
4	As a result, the DHCP server directs the system to the Cobbler server at `192.168.2.1`.
5	The DHCP server retrieves the `pxelinux.0` bootloader file.

7.1.2.2 Setting up PXE Boot in KVM #

Not necessarily for production, but for lab or demo environments you can alternativly set up PXE boot in KVM. Such a configuration can replace the next-server setting on a DHCP server explained in Section 7.1.2.1, “Configuring an Existing DHCP Server”. To edit the network XML description with virsh, proceed as follow:

Produce an XML dump of the current description:

root # virsh net-dumpxml --inactive network > network.xml

Open the XML dump file (here network.xml) with a text editor and add a bootp statement within the <dhcp> element:
```
<bootp file='/pxelinux.0' server='192.168.100.153'/>
```
Install the edited description:
```
root # virsh net-define network.xml
```

Or try the net-edit subcommand that does some error checking.

Example 7.1: Minimal Network XML Description for KVM #

<network>
  <name>default</name>
  <uuid>1da84185-31b5-4c8b-9ee2-a7f5ba39a7ee</uuid>
  <forward mode='nat'>
    <nat>
      <port start='1024' end='65535'/>
    </nat>
  </forward>
  <bridge name='virbr0' stp='on' delay='0'/>
  <mac address='52:54:00:29:59:18'/>
  <domain name='default'/>
  <ip address='192.168.100.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.100.128' end='192.168.100.254'/>
      <bootp file='/pxelinux.0' server='192.168.100.153'/>1
    </dhcp>
  </ip>
</network>

1	`bootp` statement that directs to the PXE server.

7.1.3 Xinetd and TFTP #

SUSE Manager uses the atftpd daemon, but it can also operate with Xinetd/TFTP. The atftpd is installed by default as the recommended method for providing PXE services. Usually, you do not have to change its configuration, but if you have to, use the YaST Sysconfig Editor.

Xinetd is a daemon that manages a suite of services, including TFTP, the FTP server used for transferring the boot image to a PXE client.

To configure TFTP, you must first enable the service via Xinetd. To do this, edit the /etc/xinetd.d/tftp file as root and change the disable = yes line to disable = no.

Before TFTP can serve the pxelinux.0 boot image, you must start the Xinetd service. Start YaST and use System › Services Manager to configure the Xinetd daemon.

7.1.4 Syncing TFTP Contents to SUSE Manager Proxies #

It is possible to sync cobbler generated TFTP contents to SUSE Manager Proxies to perform PXE booting via these proxies.

7.1.4.1 Installation #

On the SUSE Manager Server, install the package susemanager-tftpsync:

root # zypper install susemanager-tftpsync

On the SUSE Manager Proxy systems, install the package susemanager-tftpsync-recv:

root # zypper install susemanager-tftpsync-recv

7.1.4.2 Configuring SUSE Manager Proxy #

Execute configure-tftpsync.sh on the SUSE Manager Proxy systems.

This setup script asks for hostnames and IP addresses of the SUSE Manager server and the proxy. Additionally, it asks for the tftpboot directory on the proxy. For more information, see the output of configure-tftpsync.sh --help.

7.1.4.3 Configuring SUSE Manager Server #

Execute configure-tftpsync.sh on SUSE Manager Server:

root # configure-tftpsync.sh proxy1.example.com proxy2.example.com

Execute cobbler sync to initially push the files to the proxy systems. This will succeed if all listed proxies are properly configured.

Note: Changing the List of Proxy Systems

You can call configure-tftpsync.sh to change the list of proxy systems. You must always provide the full list of proxy systems.

Note: Reinstalling a Configured Proxy

In case you reinstall an already configured proxy and want to push all files again you must remove the cache file /var/lib/cobbler/pxe_cache.json before you can call cobbler sync again.

7.1.4.4 Requirements #

The SUSE Manager Server must be able to access the SUSE Manager Proxy systems directly. Push via proxies is not possible.

7.1.5 Syncing and Starting the Cobbler Service #

Before starting the cobbler service, run a check on the cobbler service to make sure that all the prerequisites are configured according to the organization's needs with the command: cobbler check.

If content, start the SUSE Manager server with the following command:

root # /usr/sbin/spacewalk-service start

Warning

Do not start or stop the cobblerd service independent of the SUSE Manager service. Doing so may cause errors and other issues.

Always use /usr/sbin/spacewalk-service to start or stop SUSE Manager.

7.2 Adding a Distribution to Cobbler #

If all Cobbler prerequisites have been met and Cobbler is running, you can use the Cobbler server as an installation source for a distribution: Make installation files such as the kernel image and the initrd image available on the Cobbler server. Then add a distribution to Cobbler, using either the Web interface or the command line tools.

For information about creating and configuring AutoYaST or Kickstart distributions from the SUSE Manager interface, refer to Book “Reference Manual”, Chapter 2 “Systems”, Section 2.12.6 “ Autoinstallation > Distributions ”.

To create a distribution from the command line, use cobbler as follows:

root # cobbler distro add --name=string --kernel=path --initrd=path

The --name=string option is a label used to differentiate one distribution choice from another (for example, sles12server).

The --kernel=path option specifies the path to the kernel image file.

The --initrd=path option specifies the path to the initial ram disk (initrd) image file.

7.3 Adding a Profile to Cobbler #

Once you have added a distribution to Cobbler, you can add profiles.

Cobbler profiles associate a distribution with additional options like AutoYaST or Kickstart files. Profiles are the core unit of provisioning and there must be at least one Cobbler profile for every distribution added. For example, two profiles might be created for a Web server and a desktop configuration. While both profiles use the same distribution, the profiles are for different installation types.

For information about creating and configuring Kickstart and AutoYaST profiles in the SUSE Manager interface, refer to Book “Reference Manual”, Chapter 2 “Systems”, Section 2.12.3 “Autoinstallation > Profiles (Kickstart and AutoYaST)”.

Use cobbler to create profiles on the command line:

root # cobbler profile add --name=string --distro=string [--kickstart=url] \
  [--virt-file-size=gigabytes] [--virt-ram=megabytes]

The --name=string is the unique label for the profile, such as sles12webserver or sles12workstation.

The --distro=string option specifies the distribution that will be used for this particular profile. For adding distributions, see Section 7.2, “Adding a Distribution to Cobbler”.

The --kickstart=url option specifies the location of the Kickstart file (if available).

The --virt-file-size=gigabytes option allows you to set the size of the virtual guest file image. The default is 5 GB.

The --virt-ram=megabytes option specifies how many MB of physical RAM a virtual guest can consume. The default is 512 MB.

7.4 Adding a System to Cobbler #

Once the distributions and profiles for Cobbler have been created, add systems to Cobbler. System records map a piece of hardware on a client with the cobbler profile assigned to run on it.

Note

If you are provisioning via koan and PXE menus alone, it is not required to create system records. They are useful when system-specific Kickstart templating is required or to establish that a specific system should always get specific content installed. If a client is intended for a certain role, system records should be created for it.

For information about creating and configuring automated installation from the SUSE Manager interface, refer to Book “Reference Manual”, Chapter 2 “Systems”, Section 2.3.4 “ System Details > Provisioning [Management]”.

The following command adds a system to the Cobbler configuration:

root # cobbler system add --name=string --profile=string \
  --mac-address=AA:BB:CC:DD:EE:FF

The --name=string is the unique label for the system, such as engineering_server or frontoffice_workstation.

The --profile=string specifies the name of one of the profiles added in Section 7.3, “Adding a Profile to Cobbler”.

The --mac-address=AA:BB:CC:DD:EE:FF option allows systems with the specified MAC address automatically being provisioned to the profile associated with the system record when they are being installed.

For more options, such as setting hostname or IP addresses, refer to the Cobbler manpage (man cobbler).

7.5 Using Cobbler Templates #

The SUSE Manager Web interface facilitates creating variables for use with Kickstart distributions and profiles. To create a Kickstart profile variable, refer to Book “Reference Manual”, Chapter 2 “Systems”, Section 2.12.3.1.3 “Autoinstallation Details > Variables”.

Kickstart variables are part of an infrastructural change in SUSE Manager to support templating in Kickstart files. Kickstart templates are files describing how to build actual Kickstart files rather than creating specific Kickstarts.

These templates are shared by various profiles and systems that have their own variables and corresponding values. These variables modify the templates and a template engine parses the template and variable data into a usable Kickstart file. Cobbler uses an advanced template engine called Cheetah that provides support for templates, variables, and snippets.

Advantages of using templates include:

Robust features that allow administrators to create and manage large amounts of profiles or systems without duplication of effort or manually creating Kickstarts for every unique situation.
While templates can become complex and involve loops, conditionals and other enhanced features and syntax, you can keep them simple by creating Kickstart files without such complexity.

7.5.1 Using Templates #

Kickstart templates can have static values for certain common items such as PXE image file names, subnet addresses, and common paths such as /etc/sysconfig/network-scripts/. However, templates differ from standard Kickstart files in their use of variables.

For example, a standard Kickstart file may have a networking section similar to the following:

root # network --device=eth0 --bootproto=static --ip=192.168.100.24 \
  --netmask=255.255.255.0 --gateway=192.168.100.1 --nameserver=192.168.100.2

In a Kickstart template file, the networking section would rather look like this:

root # network --device=$net_dev --bootproto=static --ip=$ip_addr \
  --netmask=255.255.255.0 --gateway=$my_gateway --nameserver=$my_nameserver

These variables will be substituted with the values set in your Kickstart profile variables or in your system detail variables. If the same variables are defined in both the profile and the system detail, then the system detail variable takes precedence.

Note

The template for the autoinstallation has syntax rules, using punctuation symbols. To avoid clashes, they need to be properly treated.

In case the autoinstallation scenario contains any shell script using variables like $(example), its content should be escaped by using the backslash symbol: \$(example).

If the variable named example is defined in the autoinstallation snippet, the templating engine will evaluate $example with its content. If there is no such variable, the content will be left unchanged. Escaping the $ symbol will prevent the templating engine to perform its evaluation as an internal variable. Long scripts or strings can be escaped by wrapping them with the #raw and #end raw directives. For example:

#raw
#!/bin/bash
for i in {0..2}; do
 echo "$i - Hello World!"
done
#end raw

Also, pay attention to similar scenarios like the following:

#start some section (this is a comment)
echo "Hello, world"
#end some section (this is a comment)

Any line with a # symbol followed by a whitespace is treated as a comment and is therefore not evaluated.

For more information about Kickstart templates, refer to the Cobbler project page at:

https://fedorahosted.org/cobbler/wiki/KickstartTemplating

7.5.2 Kickstart Snippets #

If you have common configurations across all Kickstart templates and profiles, you can use the Snippets feature of Cobbler to take advantage of code reuse.

Kickstart snippets are sections of Kickstart code that can be called by a $SNIPPET() function that will be parsed by Cobbler and substituted with the contents of the snippet.

For example, you might have a common hard drive partition configuration for all servers, such as:

clearpart --all
part /boot --fstype ext3 --size=150 --asprimary
part / --fstype ext3 --size=40000 --asprimary
part swap --recommended

part pv.00 --size=1 --grow

volgroup vg00 pv.00
logvol /var --name=var vgname=vg00 --fstype ext3 --size=5000

Save this snippet of the configuration to a file like my_partition and place the file in /var/lib/cobbler/snippets/, where Cobbler can access it.

Use the snippet by calling the $SNIPPET() function in your Kickstart templates. For example:

$SNIPPET('my_partition')

Wherever you invoke that function, the Cheetah parser will substitute the function with the snippet of code contained in the my_partition file.

7.6 Using Koan #

Whether you are provisioning guests on a virtual machine or reinstalling a new distribution on a running system, koan works in conjunction with Cobbler to provision systems.

7.6.1 Using Koan to Provision Virtual Systems #

If you have created a virtual machine profile as documented in Section 7.3, “Adding a Profile to Cobbler”, you can use koan to initiate the installation of a virtual guest on a system.

For example, create a Cobbler profile with the following command:

root # cobbler add profile --name=virtualfileserver \
  --distro=sles12-x86_64-server --virt-file-size=20 --virt-ram=1000

This profile is for a fileserver running SUSE Linux Enterprise Server 12 with a 20 GB guest image size and allocated 1 GB of system RAM.

To find the name of the virtual guest system profile, run the following koan command:

root # koan --server=hostname --list-profiles

This command lists all the available profiles created with cobbler profile add.

Start creating the image file and the installation of the virtual guest system:

root # koan --virt --server=cobbler-server.example.com \
  --profile=virtualfileserver --virtname=marketingfileserver

The command specifies that a virtual guest system be created from the Cobbler server (hostname cobbler-server.example.com) using the virtualfileserver profile. The virtname option specifies a label for the virtual guest, which by default is the system's MAC address.

Once the installation of the virtual guest is complete, it can be used as any other virtual guest system.

7.6.2 Using Koan to Reinstall Running Systems #

koan can replace a still running system with a new installation from the available Cobbler profiles by executing the following command on the system to be reinstalled:

root # koan --replace-self --server=hostname --profile=name

This command, running on the system to be replaced, will start the provisioning process and replace its own system using the profile in --profile=name on the Cobbler server specified in --server=hostname.

7.7 Building ISOs with Cobbler #

Some environments might lack PXE support. The cobbler buildiso command provides functionality to create a boot ISO image containing a set of distributions and kernels, and a menu similar to PXE network installations. Define the name and output location of the boot ISO using the --iso option.

Note: ISO Build Directory

Depending on Cobbler related systemd settings (see /usr/lib/systemd/system/cobblerd.service) writing ISO images to public tmp directories will not work.

root # cobbler buildiso --iso=/path/to/boot.iso

The boot ISO includes all profiles and systems by default. Limit these profiles and systems using the --profiles and --systems options.

root # cobbler buildiso --systems="system1,system2,system3" \
  --profiles="profile1,profile2,profile3"

Note

Building ISOs with the cobbler buildiso command is supported for all architectures except the z Systems architecture.

8 Virtualization #

Abstract#

SUSE Manager allows you to autoinstall and manage Xen and KVM VM Guests on a registered VM Host Server. To autoinstall a VM Guest, an autoinstallable distribution and an autoinstallation profile (AutoYaST or Kickstart) need to exist on SUSE Manager. VM Guests registered with SUSE Manager can be managed like “regular” machines. In addition, basic VM Guest management tasks such as (re)starting and stopping or changing processor and memory allocation can be carried out using SUSE Manager.

The following documentation is valid in the context of traditional clients. Salt minions must be treated differently: autoinstallation is still not supported and libvirt hosts are supported read-only.

8.1 Autoinstalling VM Guests

8.1.1 Requirements on SUSE Manager
8.1.2 VM Host Server Setup
8.1.3 Autoinstalling VM Guests

8.2 Managing VM Guests

8.2.1 Displaying a VM Guest's Profile
8.2.2 Starting, Stopping, Suspending and Resuming a VM Guest
8.2.3 Changing the CPU or RAM allocation of a VM Guest
8.2.4 Deleting a VM Guest

Warning: Limitation to Xen and KVM Guests

Autoinstalling and managing VM Guests via SUSE Manager is limited to Xen and KVM guests. SUSE Manager uses libvirt for virtual machine management. Currently, virtual machines from other virtualization solutions such as VMware* or VirtualBox*, are recognized as VM Guests, but cannot be managed from within SUSE Manager.

8.1 Autoinstalling VM Guests #

With SUSE Manager you can automatically deploy Xen and KVM VM Guests using AutoYaST or Kickstart profiles. It is also possible to automatically register the VM Guests, so they can immediately be managed by SUSE Manager.

8.1.1 Requirements on SUSE Manager #

Setting up and managing VM Guests with SUSE Manager does not require special configuration options. However, you need to provide activation keys for the VM Host Server and the VM Guests, an autoinstallable distribution and an autoinstallation profile. To automatically register VM Guests with SUSE Manager, a bootstrap script is needed.

8.1.1.1 Activation Keys #

Just like any other client, VM Host Server and VM Guests need to be registered with SUSE Manager using activation keys. Find details on how to set up activation keys at Book “Getting Started”, Chapter 5 “Registering Clients”, Section 5.2 “Creating Your Keys”. While there are no special requirements for a VM Guest key, at least the following requirements must be met for the VM Host Server activation key.

VM Host Server Activation Key: Minimum Requirements #

Entitlements: Provisioning, Virtualization Platform.
Packages: rhn-virtualization-host, osad.
If you want to manage the VM Host Server system from SUSE Manager (e.g. by executing remote scripts), the package rhncfg-actions needs to be installed as well.

8.1.1.2 Setting up an Autoinstallable Distribution #

To autoinstall clients from SUSE Manager, you need to provide an “autoinstallable distribution”, also referred to as autoinstallable tree or installation source. This installation source needs to be made available through the file system of the SUSE Manager host. It can for example be a mounted local or remote directory or a “loop-mounted” ISO image. It must match the following requirements:

Kernel and initrd location:
RedHat / Generic RPM #
- images/pxeboot/vmlinuz
- images/pxeboot/initrd.img
SUSE #
- boot/arch/loader/initrd
- boot/arch/loader/linux
The Base Channel needs to match the autoinstallable distribution.

Important: Autoinstallation package sources

There is a fundamental difference between RedHat and SUSE systems regarding the package sources for autoinstallation. The packages for a RedHat installation are being fetched from the Base Channel. Packages for installing SUSE systems are being fetched from the autoinstallable distribution.

As a consequence, the autoinstallable distribution for a SUSE system has to be a complete installation source (same as for a regular installation).

Procedure 8.1: Creating Autoinstallable Distribution #

Make sure an installation source is available from a local directory. The data source can be any kind of network resource, a local directory or an ISO image (which has to be “loop-mounted”). Files and directories must be world readable.
Log in to the SUSE Manager Web interface and navigate to Systems › Autoinstallation › Distributions › Create Distribution.
Fill out the form Create Autoinstallable Distribution as follows:
Distribution Label
Choose a unique name for the distribution. Only letters, numbers, hyphens, periods, and underscores are allowed; the minimum length is 4 characters. This field is mandatory.
Tree Path
Absolute local disk path to installation source. This field is mandatory.
Base Channel
Channel matching the installation source. This channel is the package source for non-SUSE installations. This field is mandatory.
Installer Generation
Operating system version matching the installation source. This field is mandatory.
Kernel Options
Options passed to the kernel when booting for the installation. There is no need to specify the install= parameter since it will automatically be added. Moreover, the parameters self_update=0 pt.options=self_update are added automatically to prevent AutoYaST from updating itself during the system installation. This field is optional.
Post Kernel Options
Options passed to the kernel when booting the installed system for the first time. This field is optional.
Save your settings by clicking Create Autoinstallable Distribution.

To edit an existing Autoinstallable Distribution, go to Systems › Autoinstallation › Distributions and click on a Label. Make the desired changes and save your settings by clicking Update Autoinstallable Distribution.

8.1.1.3 Providing an Autoinstallation Profile #

Autoinstallation profiles (AutoYaST or Kickstart files) contain all the installation and configuration data needed to install a system without user intervention. They may also contain scripts that will be executed after the installation has completed.

All profiles can be uploaded to SUSE Manager and be edited afterwards. Kickstart profiles can also be created from scratch with SUSE Manager.

A minimalist AutoYaST profile including a script for registering the client with SUSE Manager is listed in Appendix C, Minimalist AutoYaST Profile for Automated Installations and Useful Enhancements. For more information, examples and HOWTOs on AutoYaST profiles, refer to SUSE Linux Enterprise AutoYaST (https://www.suse.com/documentation/sles-12/book_autoyast/data/book_autoyast.html). For more information on Kickstart profiles, refer to your RedHat documentation.

8.1.1.3.1 Uploading an Autoinstallation Profile #

Log in to the SUSE Manager Web interface and open Systems › Autoinstallation › Profiles › Upload New Kickstart/AutoYaST File.
Choose a unique name for the profile. Only letters, numbers, hyphens, periods, and underscores are allowed; the minimum length is 6 characters. This field is mandatory.
Choose an Autoinstallable Tree from the drop-down menu. If no Autoinstallable Tree is available, you need to add an Autoinstallable Distribution. Refer to Section 8.1.1.2, “Setting up an Autoinstallable Distribution” for instructions.
Choose a Virtualization Type from the drop-down menu. KVM and Xen (para-virtualized and fully-virtualized) are available. Do not choose Xen Virtualized Host here.
Scroll down to the File to Upload dialog, click Browse to select it, then click Upload File.
The uploaded file will be displayed in the File Contents section, where you can edit it.
Click Create to store the profile.

To edit an existing profile, go to Systems › Autoinstallation › Profiles and click on a Label. Make the desired changes and save your settings by clicking Create.

Note: Editing existing Kickstart profiles

If you are changing the Virtualization Type of an existing Kickstart profile, it may also modify the bootloader and partition options, potentially overwriting any user customizations. Be sure to review the Partitioning tab to verify these settings when changing the Virtualization Type.

8.1.1.3.2 Creating a Kickstart Profile #

Note

Currently it is only possible to create autoinstallation profiles for RHEL systems. If installing a SUSE Linux Enterprise Server system, you need to upload an existing AutoYaST profile as described in Section 8.1.1.3.1, “Uploading an Autoinstallation Profile”.

Log in to the SUSE Manager Web interface and go to Systems › Autoinstallation › Profiles › Create New Kickstart File.
Choose a unique name for the profile. The minimum length is 6 characters. This field is mandatory.
Choose a Base Channel. This channel is the package source for non-SUSE installations and must match the Autoinstallable Tree. This field is mandatory.
Choose an Autoinstallable Tree from the drop-down menu. If no Autoinstallable Tree is available, you need to add an Autoinstallable Distribution. Refer to Section 8.1.1.2, “Setting up an Autoinstallable Distribution” for instructions.
Choose a Virtualization Type from the drop-down menu. KVM and Xen (para-virtualized and fully-virtualized) are available. Do not choose Xen Virtualized Host here.
Click the Next button to continue to Step 2.
Select the location of the distribution files for the installation of your VM Guests. There should already be a Default Download Location filled out and selected for you on this screen. Click the Next button to continue to Step 3.
Choose a root password for the VM Guests. Click the Finish button to generate the profile.
This completes Kickstart profile creation. After completing Step 3, you are taken to the newly-created Kickstart profile. You may browse through the various tabs of the profile and modify the settings as you see fit, but this is not necessary as the default settings should work well for the majority of cases.

8.1.1.3.3 Adding a Registration Script to the Autoinstallation Profile #

A VM Guest that is autoinstalled does not get automatically registered. Adding a section to the autoinstallation profile that invokes a bootstrap script for registration will fix this. The following procedure describes adding a corresponding section to an AutoYaST profile. Refer to your RedHat Enterprise Linux documentation for instructions on adding scripts to a Kickstart file.

First, provide a bootstrap script on the SUSE Manager:
1. Create a bootstrap script for VM Guests on the SUSE Manager as described in Book “Getting Started”, Chapter 5 “Registering Clients”, Section 5.4.1 “Generating a Bootstrap Script”.
2. Log in as root to the konsole of SUSE Manager and go to /srv/www/htdocs/pub/bootstrap. Copy bootstrap.sh (the bootstrap script created in the previous step) to e.g. bootstrap_vm_guests.sh in the same directory.
3. Edit the newly created file according to your needs. The minimal requirement is to include the activation key for the VM Guests (see Section 8.1.1.1, “Activation Keys” for details). We strongly recommend to also include one or more GPG keys (for example, your organization key and package signing keys).
Log in to the SUSE Manager Web interface and go to Systems › Autoinstallation › Profiles. Click on the profile that is to be used for autoinstalling the VM Guests to open it for editing.
Scroll down to the File Contents section where you can edit the AutoYaST XML file. Add the following snippet at the end of the XML file right before the closing </profile> tag and replace the given IP address with the address of the SUSE Manager server. See Appendix C, Minimalist AutoYaST Profile for Automated Installations and Useful Enhancementsfor an example script.
```
<scripts>
  <init-scripts config:type="list">
    <script>
      <interpreter>shell </interpreter>
      <location>
        http://192.168.1.1/pub/bootstrap/bootstrap_vm_guests.sh
      </location>
    </script>
  </init-scripts> 
</scripts>
```
Important: Only one <scripts> section allowed
If your AutoYaST profile already contains a <scripts> section, do not add a second one, but rather place the <script> part above within the existing <scripts> section!
Click Update to save the changes.

8.1.2 VM Host Server Setup #

A VM Host Server system serving as a target for autoinstalling VM Guests from SUSE Manager must be capable of running guest operating systems. This requires either KVM or Xen being properly set up. For installation instructions for SUSE Linux Enterprise Server systems refer to the SLES Virtualization Guide available from https://www.suse.com/documentation/sles-12/book_virt/data/book_virt.html. For instructions on setting up a RedHat VM Host Server refer to your RedHat Enterprise Linux documentation.

Since SUSE Manager uses libvirt for VM Guest installation and management, the libvirtd needs to run on the VM Host Server. The default libvirt configuration is sufficient to install and manage VM Guests from SUSE Manager. However, in case you want to access the VNC console of a VM Guest as a non-root user, you need to configure libvirt appropriately. Configuration instructions for libvirt on SUSE Linux Enterprise Server are available in the SLES Virtualization Guide available from https://www.suse.com/documentation/sles-12/book_virt/data/book_virt.html available from http://www.suse.com/documentation/sles11/. For instructions for a RedHat VM Host Server refer to your RedHat Enterprise Linux documentation.

Apart from being able to serve as a host for KVM or Xen guests, which are managed by libvirt, a VM Host Server must be registered with SUSE Manager.

Make sure either KVM or Xen is properly set up.
Make sure the libvirtd is running.
Register the VM Host Server with SUSE Manager:
1. Create a bootstrap script on the SUSE Manager as described in Book “Getting Started”, Chapter 5 “Registering Clients”, Section 5.4.1 “Generating a Bootstrap Script”.
2. Download the bootstrap script from susemanager.example.com/pub/bootstrap/bootstrap.sh to the VM Host Server.
3. Edit the bootstrap script according to your needs. The minimal requirement is to include the activation key for the VM Host Server (see Section 8.1.1.1, “Activation Keys” for details). We strongly recommend to also include one or more GPG keys (for example, your organization key and package signing keys).
4. Execute the bootstrap script to register the VM Host Server.
Once the registration process is finished and all packages have been installed, enable the osad (Open Source Architecture Daemon). On a SUSE Linux Enterprise Server system this can be achieved by running the following commands as user root:
```
systemctl stop rhnsd
systemctl disable rhnsd
```
```
systemctl enable osad
systemctl start osad
```
Important: osad Together with rhnsd
The rhnsd daemon checks for scheduled actions every four hours, so it can take up to four hours before a scheduled action is carried out. If many clients are registered with SUSE Manager, this long interval ensures a certain level of load balancing since not all clients act on a scheduled action at the same time.
However, when managing VM Guests, you usually want actions like rebooting a VM Guest to be carried out immediately. Adding osad ensures that. The osad daemon receives commands over the jabber protocol from SUSE Manager and commands are instantly executed. Alternatively you may schedule actions to be carried out at a fixed time in the future (whereas with rhnsd you can only schedule for a time in the future plus up to four hours).

8.1.3 Autoinstalling VM Guests #

Once all requirements on the SUSE Manager and the VM Host Server are met, you can start to autoinstall VM Guests on the host. Note that VM Guests will not be automatically registered with SUSE Manager, therefore we strongly recommend to modify the autoinstallation profile as described in Section 8.1.1.3.3, “Adding a Registration Script to the Autoinstallation Profile”. VM Guests need to be registered to manage them with SUSE Manager. Proceed as follows to autoinstall a VM Guest;.

Important: No parallel Autoinstallations on VM Host Server

It is not possible to install more than one VM Guest at a time on a single VM Host Server. When scheduling more than one autoinstallation with SUSE Manager make sure to choose a timing, that starts the next installation after the previous one has finished. If a guest installation starts while another one is still running, the running installation will be cancelled.

Log in to the SUSE Manager Web interface and click the Systems tab.
Click the VM Host Server's name to open its System Status page.
Open the form for creating a new VM Guest by clicking Virtualization › Provisioning. Fill out the form by choosing an autoinstallation profile and by specifying a name for the VM Guest (must not already exist on VM Host Server). Choose a proxy if applicable and enter a schedule. To change the VM Guest's hardware profile and configuration options, click Advanced Options.
Finish the configuration by clicking Schedule Autoinstallation and Finish. The Session Status page opens for you to monitor the autoinstallation process.

Note: Checking the Installation Log

To view the installation log, click Events › History on the Session Status page. On the System History Event page you can click a Summary entry to view a detailed log.

In case an installation has failed, you can Reschedule it from this page once you have corrected the problem. You do not have to configure the installation again.

If the event log does not contain enough information to locate a problem, log in to the VM Host Server console and read the log file /var/log/up2date. If you are using the rhnsd, you may alternatively immediately trigger any scheduled actions by calling rhn_ckeck on the VM Host Server. Increase the command's verbosity by using the options -v, -vv, or -vvv, respectively.

8.2 Managing VM Guests #

Basic VM Guest management actions such as restarting or shutting down a virtual machine as well as changing the CPU and memory allocation can be carried out in the SUSE Manager Web interface if the following requirements are met:

VM Host Server must be a KVM or Xen host.
libvirtd must be running on VM Host Server.
VM Host Server and VM Guest must be registered with SUSE Manager.

All actions can be triggered in the SUSE Manager Web interface from the Virtualization page of the VM Host Server. Navigate to this page by clicking the Systems tab. On the resulting page, click the VM Host Server's name and then on Virtualization. This page lists all VM Guests for this host, known to SUSE Manager.

8.2.1 Displaying a VM Guest's Profile #

Click the name of a VM Guest on the VM Host Server's Virtualization page to open its profile page with detailed information about this guest. For details, refer to Book “Reference Manual”, Chapter 2 “Systems”, Section 2.2 “Systems”.

A profile page for a virtual system does not differ from a regular system's profile page. You can perform the same actions (e.g. installing software or changing its configuration).

8.2.2 Starting, Stopping, Suspending and Resuming a VM Guest #

To start, stop, restart, suspend, or resume a VM Guest, navigate to the VM Host Server's Virtualization page. Check one or more Guests listed in the table and scroll down to the bottom of the page. Choose an action from the drop-down list and click Apply Action. Confirm the action on the next page.

Note: Automatically restarting a VM Guest

Automatically restarting a VM Guest when the VM Host Server reboots is not enabled by default on VM Guests and cannot be configured from SUSE Manager. Refer to your KVM or Xen documentation. Alternatively, you may use libvirt to enable automatic reboots.

8.2.3 Changing the CPU or RAM allocation of a VM Guest #

To change the CPU or RAM allocation of a VM Guest navigate to the VM Host Server's Virtualization page. Check one or more Guests from the table and scroll down to the bottom of the page. Choose an action from the Set drop-down list and provide a new value. Confirm with Apply Changes followed by Confirm.

The memory allocation can be changed on the fly, provided the memory ballooning driver is installed on the VM Guest. If this is not the case, or if you want to change the CPU allocation, you need to shutdown the guest first. Refer to Section 8.2.2, “Starting, Stopping, Suspending and Resuming a VM Guest” for details.

8.2.4 Deleting a VM Guest #

To delete a VM Guest you must first shut it down as described in Section 8.2.2, “Starting, Stopping, Suspending and Resuming a VM Guest”. Wait at least two minutes to allow the shutdown to finish and then choose Delete Systems followed by Apply Action and Confirm.

9 Inventorying vCenter/vSphere ESXi Hosts with SUSE Manager #

9.1 Introduction
9.2 Requirements
9.3 Permissions and Roles Overview
9.4 Adding New Users and Assigning Roles
9.5 Inventorying vCenter/vSphere ESXi Hosts

9.1 Introduction #

With the release of SUSE Manager 3, foreign virtual hosts (e.g. vCenter and vSphere ESXi) may be inventoried using the Virtual Host Manager. From the vSphere Client you can define roles and permissions for vCenter /vSphere ESXi users allowing vSphere objects and resources to be imported and inventoried by SUSE Manager. Objects and resources are then displayed as foreign hosts on the SUSE Manager Systems › Virtual Systems page.

The following sections will guide you through:

Requirements
Overview of permissions and roles
Adding vCenter and vSphere ESXi hosts to SUSE Manager

9.2 Requirements #

The following table displays the default API communication port and required access rights for inventorying objects and resources.

Ports / Permissions	Description
443	Default port that SUSE Manager uses to access the ESXi API for obtaining infrastructure data
read-only	All vCenter/ESXi objects and resources that should be inventoried by the Virtual Host Manager should be at least assigned the read-only role. Mark objects and resources with no-access to exclude them from the inventory.

9.3 Permissions and Roles Overview #

The following section will guide you through assigning user permissions and roles in vCenter/ESXi.

A user is someone who has been authorized access to an ESXi host. The Virtual Host Manager (located on the SUSE Manager server) will inventory ESXi data defined by assigned roles and permissions on a user account.

For example: The user John has been assigned the read-only access role to all servers and datacenters in his company with one exception. Johns account has been assigned the no-access role on the company's Financial Database server . You decide to use Johns user account and add the ESXi host to SUSE Manager. During the inventory the Financial Database server will be excluded.

Keep user access roles in mind when planning to add ESXi hosts to SUSE manager. It is important to understand that SUSE Manager will not inventory any objects or resources assigned with the no-access role on any user account.

Tip: User Roles/Permissions

When planning to add new ESXi hosts to SUSE Manager, ask yourself the following question:

Have users assigned to a host been provided with the required roles and permissions for objects and resources that should be inventoried by SUSE Manager?

9.4 Adding New Users and Assigning Roles #

See the official vSphere documentation on adding new users and assigning roles.

Authentication and User Management

9.5 Inventorying vCenter/vSphere ESXi Hosts #

The following procedure will guide you through inventorying a VSphere ESXi host with SUSE Manager.

From the SUSE Manager Web UI select Systems and then Virtual Host Managers from the left navigation bar.
From the upper right corner of the Virtual Host Managers page select Add VMware-based Virtual Host Manager.
From the Add a VMware-based Virtual Host Manager page fill the following fields with your ESXi host data:
- Label: Custom name for your Virtual Host Manager
- Hostname: FQDN or host IP address
- Port: Default ESXi API port
- Username: ESXi user
  Important
  Remember that only objects and resources which match a users defined role will be inventoried. Set the users role on objects and resources you want inventoried to read-only
- Password: ESXi users password
Click the Add Virtual Host Manager button.
From the Virtual Host Managers page select the newly added Virtual Host manager.
From the Virtual Host Managers Properties page select Refresh data from this Virtual Host Manager.
Important
If you do not refresh the data from a new Virtual Host Manager, host data will not be inventoried and therefore will not be displayed under Systems › Virtual Systems.
View inventoried ESXi host objects and resources by selecting Systems › Virtual Systems.

10 spacecmd Reference #

10.1 Introduction #

The following section will help you become more familiar with the spacecmd command-line interface. This interface is available for SUSE Manager, Satellite and Spacewalk servers. spacecmd is written in Python and uses the XML-RPC API provided by the server.

What can spacecmd do for me? #

Manage almost all aspects of SUSE Manager from the command line with spacecmd
Tab completion is available for all commands
Single commands can be passed to spacecmd without entering the interactive shell (excellent for shell scripts)
May also be accessed and used as an interactive shell
Advanced search methods are available for finding specific systems, thus removing the need to create system groups (nevertheless groups are still recommended)
Complete functionality through the Spacewalk API. Almost all commands that can be executed from the WebUI can be performed via the spacecmd command-line

10.2 Configuring spacecmd #

The following section provides configuration tips for spacecmd.

10.2.1 Setup Spacecmd Credentials #

Normally spacecmd prompts you for a username and password each time you attempt to login to the interactive shell. Alternatively you can configure spacecmd with a credentials file to avoid this requirement.

Procedure 10.1: Creating a spacecmd Credentials File #

Create a hidden spacecmd directory in your home directory and set permissions:
```
mkdir ~/.spacecmd
chmod 700 ~/.spacecmd
```
Create a config file in ~/.spacecmd/ and provide proper permissions:
```
touch ~/.spacecmd/config
chmod 600 ~/.spacecmd/config
```
Edit the config file and add the following configuration lines. (You can use either localhost or the FQDN of your SUSE Manager server):
```
[spacecmd]

server=FQDN-here

username=username-here
password=password-here
```
Check connectivity by entering spacecmd as root:
```
# spacecmd
```

10.2.2 spacecmd Quiet Mode #

By default spacecmd prints server status messages during connection attempts. These messages can cause a lot of clutter when parsing system lists. The following alias will force spacecmd to use quiet mode thus preventing this behavior. Add the following line to your ~/.bashrc file:

alias spacecmd='spacecmd -q'

10.2.3 spacecmd Help #

spacecmd help can be access by typing spacecmd -h --help

Usage: spacecmd [options] [command]

Options:
  -u USERNAME, --username=USERNAME
                        use this username to connect to the server
  -p PASSWORD, --password=PASSWORD
                        use this password to connect to the server
  -s SERVER, --server=SERVER
                        connect to this server [default: local hostname]
  --nossl               use HTTP instead of HTTPS
  --nohistory           do not store command history
  -y, --yes             answer yes for all questions
  -q, --quiet           print only error messages
  -d, --debug           print debug messages (can be passed multiple times)
  -h, --help            show this help message and exit

As root you can access available functions without entering the spacecmd shell:

# spacecmd -- help

10.3 Troubleshooting #

This section provides troubleshooting solutions when working with spacecmd

10.3.1 Creating a Distribution With spacecmd Sets Localhost Instead of FQDN #

The support article associated with this issue may be located at:https://www.suse.com/support/kb/doc/?id=7018627

Situation

When creating a distribution with spacecmd it will automatically set localhost as the server name instead of the FQDN of SUSE Manager. This will result in the following kernel option being written:

install=http://localhost/ks/dist/<distributionname>

Resolution

Set the FQDN in $HOME/.spacecmd/config like the following:

test:~/.spacecmd # cat config
[spacecmd]
server=test.mytest.env
username=admin
password=password
nossl=0

Cause

This problem may be experienced if $HOME/.spacecmd/config has been created and the server name option was set to localhost.

10.4 spacecmd Functions #

The following sections provide descriptions for all documented spacecmd commands. Each command is grouped by the function prefix. Keep in mind that all commands may also be called using scripts and passed to spacecmd as stand-alone commands.

10.4.2 api #

The following API command and its options are available for calling the XML-RPC API directly. Calling the API directly allows you to use the latest features in SUSE Manager from the command-line using spacecmd as a wrapper for stand-alone commands or used from within scripts.

Note: Use the api Command for Access to Latest Features

spacecmd is the traditional tool for spacewalk. It functions out of the box with SUSE Manager but you should know that latest features (for example, Salt) are often excluded from traditional spacecmd command-line tool. To gain access to the latest feature additions call api api.getApiCallList from within spacecmd to list all currently available API commands formatted in json. You can then call these commands directly.

api

Call XML-RPC API with arguments directly.

usage: api [options] API_STRING

options:
  -A, --args  Arguments for the API other than session id in comma separated
              strings or JSON expression
  -F, --format   Output format
  -o, --output   Output file

examples:
  api api.getApiCallList
  api --args "sysgroup_A" systemgroup.listSystems
  api -A "rhel-i386-server-5,2011-04-01,2011-05-01" -F "%(name)s" \
      channel.software.listAllPackages

10.4.3 clear #

Clears the terminal screen

10.4.4 clear_caches #

Clear the internal caches kept for systems and packages

usage: clear_caches

10.4.5 configchannel_ #

The following spacecmd commands are available for use with configuration channels.

configchannel_addfile

Creates a configuration file.

  -d path is a directory
  -s path is a symlink
  -b path is a binary (or other file which needs base64 encoding)
  -t SYMLINK_TARGET
  -f local path to file contents

  Note re binary/base64: Some text files, notably those containing trailing
  newlines, those containing ASCII escape characters (or other charaters not
  allowed in XML) need to be sent as binary (-b).  Some effort is made to auto-
  detect files which require this, but you may need to explicitly specify.

configchannel_backup

Backup a configuration channel.

usage: configchannel_backup CHANNEL [OUTDIR]

OUTDIR defaults to $HOME/spacecmd-backup/configchannel/YYYY-MM-DD/CHANNEL

configchannel_clone

Clone configuration channel(s).

A.4 Syncing SUSE Manager Repositories from SCC (mgr-sync)

A.5 Configuring SUSE Manager's Database (smdba)

A.5.1 Control Options
A.5.2 Starting and Stopping the Database

In addition to the SUSE Manager Web interface, SUSE Manager offers two command line tools for managing system configuration files: the Configuration Client and the Configuration Manager. There is a complementary Actions Control tool used to enable and disable configuration management on client systems. If you do not yet have these tools installed, they can be found in the SUSE Manager Tools child channel for your operating system (package names are: rhncfg-client, rhncfg-manager, and rhncfg-actions).

Note: Tip

Whenever a configuration file is deployed via SUSE Manager, a backup of the previous file including its full path is stored in the /var/lib/rhncfg/backups/ directory on the affected system. The backup retains its filename but has a .rhn-cfg-backup extension appended.

A.1 Actions Control (`mgr-actions-control`) #

The Actions Control (mgr-actions-control) application is used to enable and disable configuration management on a system. Client systems cannot be managed in this fashion by default. This tool allows SUSE Manager administrators to enable or disable specific modes of allowable actions such as: deploying a configuration file on the system, uploading a file from the system, using the diff command to find out what is currently managed on a system with what is available, or running remote commands. These various modes are enabled/disabled by placing/removing files and directories in the /etc/sysconfig/rhn/allowed-actions/ directory. Due to the default permissions of the /etc/sysconfig/rhn/ directory, Actions Control has to be run by someone with root access.

A.1.1 General command line options #

There is a manpage available, as for most command line tools. First, decide which scheduled actions should be enabled for use by system administrators. The following options enable the various scheduled action modes:

--enable-deploy: Allow mgrcfg-client to deploy files.
--enable-diff: Allow mgrcfg-client to diff files.
--enable-upload: Allow mgrcfg-client to upload files.
--enable-mtime-upload: Allow mgrcfg-client to upload mtime (file modification time).
--enable-all: Allow mgrcfg-client to do everything.
--enable-run: Enable running scripts.
--disable-deploy: Disable deployment.
--disable-diff: Prohibit diff use.
--disable-upload: No file uploads allowed.
--disable-mtime-upload: Disable mtime upload.
--disable-all: Disable all options.
--disable-run: No scripts allowed to run.
--report: Report whether modes are enabled or disabled.
-f, --force: Force the operation without asking first.
-h, --help: Show help message and exit.

Once a mode is set, your system is ready for configuration management through SUSE Manager. A common option is mgr-actions-control --enable-all.

A.2 Configuration Client (`mgrcfg-client`) #

As the name implies, the Configuration Client (mgrcfg-client) is installed on and run from an individual client system to gain knowledge about how SUSE Manager deploys configuration files to the client.

The Configuration Client offers these primary modes: list, get, channels, diff, and verify.

A.2.1 Listing Config Files #

To list the configuration files for the machine and the labels of the config channels containing them, issue the command:

mgrcfg-client list

The output resembles the following list (“DoFoS” is a shortcut for “D or F or S”, which means “Directory”, “File”, or “Something else”(?)):

DoFoS   Config Channel      File
F      config-channel-17   /etc/example-config.txt
F      config-channel-17   /var/spool/aalib.rpm
F      config-channel-14   /etc/rhn/rhn.conf

These configuration files apply to your system. However, there may be duplicate files present in other channels. For example, issue the following command:

mgrcfg-manager list config-channel-14

and observe the following output:

Files in config channel 'config-channel-14'
/etc/example-config.txt /etc/rhn/rhn.conf

You may wonder why the second version of /etc/example-config.txt in config-channel-14 does not apply to the client system. The rank of the /etc/example-config.txt file in config-channel-17 was higher than that of the same file in config-channel-14. As a result, the version of the configuration file in config-channel-14 is not deployed for this system, therefore mgrcfg-client command does not list the file.

A.2.2 Getting a Config File #

To download the most relevant configuration file for the machine, issue the command:

mgrcfg-client get /etc/example-config.txt

You should see output resembling:

Deploying /etc/example-config.txt

View the contents of the file with less or another pager. Note that the file is selected as the most relevant based on the rank of the config channel containing it. This is accomplished within the Configuration tab of the System Details page. Refer to Book “Reference Manual”, Chapter 2 “Systems”, Section 2.3 “System Details” for instructions.

A.2.3 Viewing Config Channels #

To view the labels and names of the config channels that apply to the system, issue the command:

mgrcfg-client channels

You should see output resembling:

Config channels:
Label                   Name
-----                   ----
config-channel-17       config chan 2
config-channel-14       config chan 1

The list of options available for mgrcfg-client get:

--topdir=TOPDIR: Make all file operations relative to this string.
--exclude=EXCLUDE: Exclude a file from being deployed with get. May be used multiple times.
-h, --help: Show help message and exit.

A.2.4 Differentiating between Config Files #

To view the differences between the config files deployed on the system and those stored by SUSE Manager, issue the command:

mgrcfg-client diff

The output resembles the following:

rhncfg-client diff
--- /etc/test
+++ /etc/test 2013-08-28 00:14:49.405152824 +1000
@@ -1 +1,2 @@
This is the first line
+This is the second line added

In addition, you can include the --topdir option to compare config files with those located in an arbitrary (and unused) location on the client system, like this:

# mgrcfg-client diff --topdir /home/test/blah/
/usr/bin/diff: /home/test/blah/etc/example-config.txt: No such file or directory
/usr/bin/diff: /home/test/blah/var/spool/aalib.rpm: No such file or directory

A.2.5 Verifying Config Files #

To quickly determine if client configuration files are different from those associated with it via SUSE Manager, issue the command:

mgrcfg-client verify

The output resembles the following:

modified /etc/example-config.txt /var/spool/aalib.rpm

The file example-config.txt is locally modified, while aalib.rpm is not.

The list of the options available for mgrcfg-client verify:

-v, --verbose: Increase the amount of output detail. Display differences in the mode, owner, and group permissions for the specified config file.
-o, --only: Only show differing files.
-h, --help: Show help message and exit.

A.3 Configuration Manager (`mgrcfg-manager`) #

The Configuration Manager (mgrcfg-manager) is designed to maintain SUSE Manager's central repository of config files and channels, not those located on client systems. This tool offers a command line alternative to the configuration management features in the SUSE Manager Web interface. Additionally, some or all of the related maintenance tasks can be scripted.

To use the command line interface, configuration administrators require a SUSE Manager account (username and password) with the appropriate permission set. The username may be specified in /etc/sysconfig/rhn/rhncfg-manager.conf or in the [rhncfg-manager] section of ~/.rhncfgrc.

When the Configuration Manager is run as root, it attempts to pull in needed configuration values from the Red Hat Update Agent. When run as a user other than root, you may have to change the ~/.rhncfgrc configuration file. The session file is cached in ~/.rhncfg-manager-session to avoid having to log in for every command.

The default timeout for the Configuration Manager is 30 minutes. To alter this, add the server.session_lifetime option and a new value to the /etc/rhn/rhn.conf file on the server running the manager, for example set the time out to 120 minutes:

server.session_lifetime = 120

The Configuration Manager offers these primary modes: add, create-channel, diff, diff-revisions, download-channel, get, list, list-channels, remove, remove-channel, revisions, update, and upload-channel.

Each mode offers its own set of options, which can be displayed by issuing the following command:

mgrcfg-manager mode --help

Replace mode with the name of the mode whose options you want to see:

mgrcfg-manager diff-revisions --help

Find a list of options for the add mode in Section A.3.2, “Adding Files to a Config Channel”.

A.3.1 Creating a Config Channel #

To create a config channel for your organization, issue the command:

mgrcfg-manager create-channel channel-label

If prompted for your SUSE Manager username and password, provide them.

Once you have created a config channel, use the remaining modes listed above to populate and maintain that channel.

A.3.2 Adding Files to a Config Channel #

To add a file to a config channel, specify the channel label and the local file to be uploaded:

mgrcfg-manager add --channel=channel-label /path/to/file

In addition to the required channel label and the path to the file, you can use the available options for modifying the file during its addition. For instance, you can alter the path and file name by including the --dest-file option in the command:

mgrcfg-manager add --channel=channel-label \
  --dest-file=/new/path/to/file.txt/path/to/file

The output resembles the following:

Pushing to channel example-channel
Local file >/path/to/file -> remote file /new/path/to/file.txt

The list of options available for mgrcfg-manager add:

-c CHANNEL --channel=CHANNEL: Upload files in this config channel.
-d DEST_FILE --dest-file=DEST_FILE: Upload the file as this path.
--delim-start=DELIM_START: Start delimiter for variable interpolation.
--delim-end=DELIM_END: End delimiter for variable interpolation.
-i, --ignore-missing: Ignore missing local files.
-h, --help: Show help message and exit.

Note

By default, the maximum file size for configuration files is 128KB. If you need to change that value, find or create the following line in the /etc/rhn/rhn.conf file:

web.maximum_config_file_size=128

Change the value from 128 to whatever limit you want in kilo bytes.

A.3.3 Differentiating between Latest Config Files #

To view the differences between the config files on disk and the latest revisions in a channel, issue the command:

mgrcfg-manager diff --channel=channel-label --dest-file=/path/to/file.txt \
/local/path/to/file

You should see output resembling:

--- /tmp/dest_path/example-config.txt config_channel: example-channel revision: 1
+++ /home/test/blah/hello_world.txt 2003-12-14 19:08:59.000000000 -0500

-d DEST_FILE, --dest-file=DEST_FILE: Upload the file at this path.
-t TOPDIR, --topdir=TOPDIR: Make all files relative to this string.
-h, --help: Show help message and exit.

A.3.4 Differentiating between Various Versions #

To compare different versions of a file across channels and revisions, use the -r flag to indicate which revision of the file should be compared and the -n flag to identify the two channels to be checked. Refer to Section A.3.11, “Determining the Number of File Revisions” for related instructions. Specify only one file name here since you are comparing the file against another version of itself. For example:

mgrcfg-manager diff-revisions -n=channel-label1 -r=1 \
  -n=channel-label2 -r=1 \
  /path/to/file.txt

The output resembles the following:

--- /tmp/dest_path/example-config.txt 2004-01-13 14:36:41 \

A.4 Syncing SUSE Manager Repositories from SCC (`mgr-sync`) #

mgr-sync is the new tool replacing mgr-ncc-sync. mgr-sync must be used, if SUSE Manager is connected to SUSE Customer Center (SCC). With mgr-sync you add or synchronize products and channels. It also enables and refreshes SCC data. This tool requires that SCC is enabled by running mgr-sync enable-scc first.

mgr-sync has a new command structure using sub-commands similar to git or osc. For a complete list of command line option, see the mgr-sync manpage (man mgr-sync). Basic actions are:

mgr-sync enable-scc

mgr-sync list channel(s)|product(s)|credentials
mgr-sync add  channel(s)|product(s)|credentials
mgr-sync delete  credentials

mgr-sync refresh [--refresh-channels] [--from-mirror MIRROR]

Here are some usage examples. List channels:

mgr-sync list channels

Add a channel:

mgr-sync add channel LABEL

List products:

mgr-sync list products

Add a product:

mgr-sync add product

Refresh the data:

mgr-sync refresh

Refresh the data and schedule reposync of all installed vendor channels:

mgr-sync refresh --refresh-channels

mgr-sync now requires username/password of a “SUSE Manager administrator”. Most of the functions are available as a public API now.

List SCC credentials:

mgr-sync list credentials

Add new SCC credentials:

mgr-sync add credentials

To add SCC primary credentials:

mgr-sync add credentials --primary

There can be one primary credential only. This is username/password used first when retrieving the list of available channels and packages.

Delete SCC credentials:

mgr-sync delete credentials

A.5 Configuring SUSE Manager's Database (smdba) #

SUSE Manager provides the smdba command for managing the installed database. It is the successor of db-control, which is not supported anymore.

The smdba command works on local databases only, not remote. This utility allows you to do several administrative tasks like backing up and restoring the database, everything from creating, verifying, and restoring backups to obtaining the database status, and restart the database if necessary. The smdba command supports postgresql; and Oracle databases.

Find basic information about smdba in the smdba manpage.

Note: Restart Spacewalk Services When Connection is Lost

If you have stopped or restarted the database, it can happen that the Spacewalk services lost their connections. In such a case, run the following command:

spacewalk-service restart

A.5.1 Control Options #

Depending on the database installed, smdba provides several subcommands:

Example A.1: Available Options on a Machine with an Oracle Database #

C Minimalist AutoYaST Profile for Automated Installations and Useful Enhancements #

The following AutoYaST profile will install a SUSE Linux Enterprise Server system with all default installation options including a default network configuration with DHCP. After the installation is completed, a bootstrap script located on the SUSE Manager server will be executed in order to register the freshly installed system with SUSE Manager. You need to adjust the IP address of the SUSE Manager server, the name of the bootstrap script and the root password according to your needs in the following lines:

<user>
 ...
 <username>root</username>
 <user_password>linux</user_password>
</user>

   <product>$c_product</product>
   <product_dir>/</product_dir>
  </listentry>
...
 </add_on_products>
</add-on>

Replace channel-label and distribution-label with actual labels such as sles11-sp1-updates-x86_64 and sles11-sp2-x86_64 (the distribution label must correspond to the Autoinstallable Distribution!), and set the variables ($c_server, etc.) according to your environment. For information about variables, see Book “Reference Manual”, Chapter 2 “Systems”, Section 2.12.6.1 “ Autoinstallation > Distributions > Variables ”.

Important: Add the Updates Channel

It is required to add the updates tools channel to the <add-on> AutoYaST snippet section. This ensures your systems are provided with an up-to-date version of libzypp. Without the inclusion of an updates channel you will encounter 400 errors. See the following example where the (DISTRIBUTION_NAME) is replaced with the name of the autoinstallation distribution created previously in Systems › Autoinstallation › Distributions

The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.

The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none.

The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words.

A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque".

Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only.

The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text.

A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to this definition.

The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License.

2. VERBATIM COPYING #

You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.

You may also lend copies, under the same conditions stated above, and you may publicly display copies.

3. COPYING IN QUANTITY #

If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.

If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.

If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.

It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.

4. MODIFICATIONS #

You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:

Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission.
List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement.
State on the Title page the name of the publisher of the Modified Version, as the publisher.
Preserve all the copyright notices of the Document.
Add an appropriate copyright notice for your modifications adjacent to the other copyright notices.
Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below.
Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice.
Include an unaltered copy of this License.
Preserve the section Entitled "History", Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled "History" in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence.
Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the "History" section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission.
For any section Entitled "Acknowledgements" or "Dedications", Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein.
Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles.
Delete any section Entitled "Endorsements". Such a section may not be included in the Modified Version.
Do not retitle any existing section to be Entitled "Endorsements" or to conflict in title with any Invariant Section.
Preserve any Warranty Disclaimers.

If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles.

You may add a section Entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties--for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.

You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.

The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version.

5. COMBINING DOCUMENTS #

You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers.

The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work.

In the combination, you must combine any sections Entitled "History" in the various original documents, forming one section Entitled "History"; likewise combine any sections Entitled "Acknowledgements", and any sections Entitled "Dedications". You must delete all sections Entitled "Endorsements".

6. COLLECTIONS OF DOCUMENTS #

You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.

You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document.

7. AGGREGATION WITH INDEPENDENT WORKS #

A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an "aggregate" if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document.

If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate.

8. TRANSLATION #

Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail.

If a section in the Document is Entitled "Acknowledgements", "Dedications", or "History", the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title.

9. TERMINATION #

You may not copy, modify, sublicense, or distribute the Document except as expressly provided for under this License. Any other attempt to copy, modify, sublicense or distribute the Document is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

10. FUTURE REVISIONS OF THIS LICENSE #

The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/.

Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation.

ADDENDUM: How to use this License for your documents #

   Copyright (c) YEAR YOUR NAME.
   Permission is granted to copy, distribute and/or modify this document
   under the terms of the GNU Free Documentation License, Version 1.2
   or any later version published by the Free Software Foundation;
   with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
   A copy of the license is included in the section entitled “GNU
   Free Documentation License”.

If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the “with...Texts.” line with this:

   with the Invariant Sections being LIST THEIR TITLES, with the
   Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.

If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation.

If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
