Novell Doc: Novell ZENworks 7 Desktop Management Administration Guide

K.17 July 14, 2006 (Support Pack 1)

Many updates too numerous to mention here concerning the use of Linux servers in Preboot Services imaging are made to the Workstation and Server Imaging section of this Administration Guide. The following sections detail some of those changes.

Updates are made to the following guide sections:

K.17.1 Imaging Utilities and Components

The following changes are made in this section:

Location	Change
Section 63.5, Imaging Configuration Parameters (Settings.txt)	Removed the following information from the end of this section and replaced it with the new information contained in Section 67.0, Accessing IP Addresses for Devices Running Dual NICs: If you have problems obtaining an IP address for a workstation running dual NICs, put the following line in the settings.txt file: export VALIDATE_NIC=$PROXYADDR This line in the settings.txt file validates the NICs; you might notice a small performance decrease in the time it takes to obtain an IP address for the workstation.
Section 63.6.1, Initiating the Imaging Processes on Linux Imaging Servers	Added this section.

Section 63.5, Imaging Configuration Parameters (Settings.txt)

Removed the following information from the end of this section and replaced it with the new information contained in Section 67.0, Accessing IP Addresses for Devices Running Dual NICs:

If you have problems obtaining an IP address for a workstation running dual NICs, put the following line in the settings.txt file:

export VALIDATE_NIC=$PROXYADDR

This line in the settings.txt file validates the NICs; you might notice a small performance decrease in the time it takes to obtain an IP address for the workstation.

Section 63.6.1, Initiating the Imaging Processes on Linux Imaging Servers

Added this section.

K.17.2 Multicasting Images

The following changes are made in this section:

Location	Change
Initiating a Multicast Session from a Linux ZENworks Imaging Server	Added this section.

K.17.3 Preparing an Imaging Boot Method

The following changes are made in this section:

Location	Change
Section 55.3, Using the ZENworks Imaging Boot Disk Creator	Updated this section.
Section 55.4, Creating an Imaging Hard-Disk Partition	Updated this section.

K.17.4 Preparing a ZENworks Imaging Server

The following changes are made in this section:

Location	Change
Section 54.1, Imaging Server Prerequisites	Added the following bullet: Proxy DHCP server (Linux imaging servers only): To avoid confusion, the Proxy DHCP daemon (novell-proxydhcp) is installed, but not enabled. For PXE devices to be able to communicate with Preboot Services, this daemon must be started manually on at least one server on each network segment. Exactly how many servers and which specific servers should run this daemon is dictated by your network topology. As a rule of thumb, for every DHCP server deployed in your network, you should have a corresponding Proxy DHCP server.
