New Registration Procedure and Functionality

The new registration procedure helps customers to manage their systems with Novell's infrastructure. Once registered, packages and patch sources suitable for the current system are automatically detected and made available to the package management system (zmd). Register as part of the installation procedure, using the YaST module, or with the suse_register command.

The registration procedure transfers zmd's unique device identifier to Novell's registration Web service. To determine the appropriate packages and package sources, information about the hardware architecture, operating system, and version is also sent. The current time zone is transmitted then used to select a source mirror site in your area.

To provide maximum flexibility, Novell's Web service asks for required parameters depending on the needs of the registration procedure. The following local commands may be run to determine the needed information:

PRIVACY: To allow for maximum customer privacy, the procedure can be configured to deny optionally requested parameters. It is still possible to register, but the experience may be less user-friendly because many human readable system parameters will not be displayed. If you do not register, the underlying system will continue to work. However, the registration service cannot provide the online update configuration unless registration is performed to pass mandatory information, including product, operating system type and version, and CPU type.

If you send only the mandatory information, your system is configured for getting online updates from an appropriate source. If you have a purchased version of SUSE Linux, you can send optional information to register for your installation support. Sending the optional information for SUSE Linux Enterprise products gives access to a wide range of additional features. See the Novell Web site for details.

German Support Contact Information

The phone numbers for the Free and Advanced Support in Germany are incorrect in the Start-Up manual, Chapter 9.7. Use the following numbers:

Online Update Configuration

If you skip Online Update Configuration during the installation and perform it later, you cannot see update packages listed in YaST even if ZENworks (rug or Software Updater) shows them. As a work-around after running the Online Update Configuration, run rug refresh as root from the command line, which lets YaST know about the update catalog.

AppArmor's Default Profiles

This release of SUSE Linux Server ships with Novell AppArmor, which can protect your applications from software exploits. AppArmor protection can be enabled via the AppArmor control panel, which is located in YaST under Novell AppArmor.

The AppArmor profiles included with SUSE Linux have been developed in conjunction with our best efforts to reproduce how most users will use their software. The profiles we have provided will work unmodified for many users—however, some users will find our profiles too restrictive for their environments.

If you discover that some of your applications do not function as you expected, you may need to use the AppArmor Update Profile Wizard in YaST (or use the aa-logprof command line utility) to update your AppArmor profiles. You may place all your profiles into learning mode with the following:

aa-complain /etc/apparmor.d/*

When a program generates many complaints, the system's performance will be degraded; to mitigate this, we recommend periodically running the Update Profile Wizard (or aa-logprof) to update your profiles even if you choose to leave them in learning mode. This will reduce the number of learning events logged to disk which will improve the performance of the system.

Add-On CD-ROM with Binary-Only Software

SUSE Linux comes with an add-on CD-ROM (CD6) that contains binary-only software. On this CD-ROM, find, for example, the firmware for WLAN cards such as Intel Centrino or an alternative Java engine.

Include the add-on medium by activating the "Include Add-On Products from Separate Media" option in the YaST installation type dialog at the beginning of the installation or update.

Firefox com Suporte Pango

On some computers, Firefox with Pango support enabled is very slow. The performance seems to depend on the X server. Set MOZ_DISABLE_PANGO=0 if you want to switch on font rendering for your environment anyway:



Notes to the Translated Manuals (es, fr, it, ja, zh_CN, and zh_TW)

The English, German, and Czech manuals are the mandatory reference if the contents of a language version differs from the English text due to late software changes. Here is the list of noteworthy differences in the Start-Up manual:


Updating Software Packages

To apply security updates and install additional software packages, use the ZENworks updater applet for KDE and GNOME, which replaces SUSEwatcher. The ZENworks updater helps monitor available patches. The Online Updater from within the YaST Control Center is an alternative for updating software that uses the package manager interface.

For automatic update, use rug, which replaces the YaST Online Update (YOU) in cron tables.

For more information about the ZENworks updater, see the PDF online documentation on the first installation medium (docu/en/applying_patches.pdf). More information about rug is available in the SUSE Linux Start-Up Manual.

Preparing for Remote Update

Before starting a remote update (for example, with VNC), make sure that the firewall of your system is configured accordingly. Use YaST to open the ports that are required to access your system remotely. Start the YaST Control Center. Then click "Network Services" -> "Remote Administration" and select "Allow Remote Administration". If necessary, activate "Open Port in Firewall".

Read the YaST help text for more information.

Configuring the FTP Server (vsftpd)

Starting with SUSE Linux 10.1, the vsftpd FTP server can be configured to run independently or using the xinetd superdaemon. The default is now for independent use—in previous versions, the default was to use xinetd. To run it with xinetd, enable the service in the xinetd configuration file (/etc/xinetd.d/vsftpd) and set the following option line in /etc/vsftpd.conf:


A actualizar para MySQL 5.0

SUSE Linux comes with MySQL 5.0. As with every major release update, it is strongly recommended to perform a backup of the MySQL table files and create an SQL dump beforehand. After the update, /etc/init.d/mysql automatically executes mysql_fix_privilege_tables. Refer to for more information and detailed instructions.


A instalação é descrita no Guia de Arranque.

About Contents of DVD and CD-ROM Media

SUSE Linux can be installed from either the DVD or a set of CD-ROM media. However, not all packages fit on the CD-ROMs. Only those users install most often are included. Find an overview listing the differences at

If your system lacks a DVD drive and you need a certain package, either put the DVD in another machine connected with your network and mount it remotely for installation or use YaST to select a public FTP server as an installation source.


Using the Hardware Compatibility List

If you encounter nonfunctional hardware, check the Hardware Compatibility List at The list also offers tips on how to get certain hardware working, including information about third-party drivers for hardware, such as video cards.

Detecting Laptops Properly

Because some laptops cannot be detected properly, the Laptop Selection is not enabled automaticaly. To add the laptop selection, start the YaST software package management and select "Laptop Selection" manually. If NetworkManager is not set up by default on your laptop, configure it manually during the network configuration.

sudo without X Forwarding

For security reasons, sudo no longer does X forwarding. If you want to start an X program such as YaST that requires root permissions, either become root first using su or call it through ssh as follows:

ssh -X -l root localhost yast2

ATI Radeon Support: radeon versus radeonold Driver

With X.Org 6.9, the latest radeon driver is included, which supports nonrectangular MergedFB, RN50/ES1000 chips, VIVO, and BIOS hotkeys among other features. Our customers have been waiting for this impatiently for quite some time. Because several of these features touch very low level parts of the driver and customers have experienced problems with some chipset revisions, we also ship the version of the radeon driver already available on SUSE Linux 10.0 as a fallback with a reduced feature set—for example, it does not support DRI ("3D"). This old driver is called "radeonold". This old driver is not supported, because it is no longer actively developed.

If you encounter problems with the radeon driver, switch to the "radeonold" driver, which can be configured using SaX2. On a console prompt, enter sax2 -m 0=radeonold for configuration.

X Configuration: Dual Head Support with i830 Chipsets

With some older i830 chipsets, dual head support for the X Window System is not available. Deactivate the dual head setting in the YaST hardware configuration dialog when installing SUSE Linux or manually run SaX2 (sax2) after installing SUSE Linux to deactivate dual head.

JogDial Support on Sony Laptops

Because the sonypi kernel module does not work on recent Sony laptops, automatic loading of this module has been disabled. If you know that this kernel module does not cause trouble on your laptop, add sonypi to MODULES_LOADED_ON_BOOT in /etc/sysconfig/kernel.

Changes with Kernel Modules

The following kernel modules are no longer available:

The following kernel module package was changed internally:

For technical reasons, it was necessary to drop support for Ralink WLAN cards. The old driver no longer works with kernel version 2.6.16 and the new version is not yet stable enough. We intend to release an update as soon as the new version is stable enough.

Find additional drivers in the kmp packages. For background information, see

A Desactivar o Serviço de Powersave

On some machines, CPU frequency scaling can cause hangs when the machine is idle or when powersaved starts. In these cases, disable the powersave daemon at the installation with POWERSAVE=off as a boot parameter.

Quando este parâmetro não é fornecido no arranque inicial do CD de instalação, o powersaved deve ser desactivado posteriormente utilizando chkconfig powersaved off.

APIC de IO e Local

APIC de IO e Local para a arquitectura de 32-bit x86 mudou. Um APIC de IO e Local (I/O Advanced Programmable Interrupt Controller) é uma substituição capaz de fazer SMP para controladores de interrupção de PC's. Os sistemas SMP e todos os sistemas uniprocessador recentes têm um controlador deste tipo.

Até agora, o APIC de IO e Local estava desactivado por pré-definição em sistemas uniprocessador, e tinha de ser manualmente activado pela utilização do parâmetro "apic" de kernel. Agora, este é executado por pré-definição, e pode ser manualmente desactivado. Para sistemas de 64-bit, o APIC encontra-se sempre activado por definição.

Se experimentar problemas com dispositivos que não funcionem correctamente, pode aplicar manualmente as seguintes opções de configuração:

Definições de ulimit

As definições de ulimit podem ser configuradas em /etc/sysconfig/ulimit. Por pré-definição, apenas dois limites são alterados em relação às pré-definições do kernel:

Estes limites 'soft' podem ser sobrepostos pelo utilizador, com o comando ulimit. O limites 'hard' podem apenas ser sobrepostos pelo utilizador root.

Os valores foram escolhidos de forma conservadora com o objectivo de evitar grandes fugas de processos que têm trabalhado anteriormente. Se não existem processos que legitimamente consumam muita memória, defina os limites para um valor inferior, por forma a proporcionar uma protecção acrescida contra processos em fuga. Os limites são por processo e por isso não são uma protecção efectiva contra utilizadores maliciosos. Os limites são pensados para proteger contra uma utilização excessiva e acidental de memória.

Para configurar diferentes limites dependendo do utilizador, utilize a funcionalidade pam_limits e configure /etc/security/limits.conf. O pacote ulimit não é necessário para tal, mas ambos os mecanismos podem ser utilizados em paralelo. Os limites configurados em limits.conf sobrepõem-se às pré-definições globais do pacote ulimit.

Unlocking CD and DVD Drives and Ejecting Media

On SUSE Linux 10.1 a new mounting mechanism replaces the submount system used earlier. This new mechanism does not unmount media automatically, but on hardware request. Some devices, most notably older CD drives but also some new drives with broken firmware, do not send this signal. To eject the media on such devices, select Eject in the context menu (opened by right-clicking) of the device in "My Computer" or select Eject in the context menu of the device icon on the desktop.
