OES2 DHCP - How to add a Manual IP address assignments to novell-dhcp configuration

This document (7003452) is provided subject to the disclaimer at the end of this document.


Novell Open Enterprise Server 2 (OES 2) Linux


How to add a Manual IP address assignments to novell-dhcp configuration.


Using iManager to create manual host entries:

Launch iManager > Select DHCP (OES Linux) > Select Host > Create Host > Select the Service > Select the Subnet > Fill in the Host Name, Host IP Address, Client Identifier, MAC Type, and MAC Address > click Create.

This results in that manual host information being stored in eDir.

When the Novell DHCP daemon starts up (rcnovell-dhcp start) it reads the manual host information from eDir and writes it to the /var/log/dhcp-ldap-startup.log file.
This file is a text file that gets overwritten with the information from eDir when the DHCP daemon starts up.

The entry will look something like this:

host <WindowsNetBIOSNameHere> {
hardware ethernet 00:1d:22:05:1e:8a;
default-lease-time 2147483647;
option dhcp-client-identifier 00:1d:22:05:1e:8a;

These manual assignments must be outside the range of any dynamic pools.

If the manual assignment falls within the range of a dynamic pool the address may get handed out dynamically.

Best practice is to set aside enough addresses at the beginning of the subnet to be used for manual assignments and define dynamic pools after those addresses.

In the case where you already have a dynamic pool with manual addresses that would land within the range of that dynamic pool, the dynamic pool will need to be redefined and broken up into multiple dynamic pools that do not include the manual

Your existing manual assignments are:, and cannot change.
Your subnet is,
The pools can be defined as follows: and -, and -

Additional Information

If there are manual assignments existing in dynamic pools those manual addresses may get handed out dynamically.
When this happens you may see in the dhcpd.log file the following error information:

Dynamic and Static leases present for
Remove host declaration <hostname> or remove from the dynamic address pool for

These will probably be followed by a DHCP Request and a DHCP Ack where the manual IP address is being dynamically handed out.
