ZENworks Configuration Management - imaging, PXE and DHCP
By Martin Buckley
ZENworks imaging can use the Preboot eXecution Environment - PXE - to start its imaging engine.
When the imaging server components (TFTP server, Imaging engine, Proxy DHCP) are running on the same server as the DHCP server there are certain configuration changes that need to be made.
Read the ZCM10 documentation for more.
Three steps to happiness - I'll document this for Windows; SLES is broadly similar.
- set the Proxy DHCP to run correctly
- set Proxy DHCP to start automatically
- add DHCP option tag 60 to the DHCP scope
Setting Proxy DHCP to co-exist with the local DHCP server
Edit %ZENWORKS_HOME%\conf\preboot\novell-proxydhcp.conf
Change the line: LocalDHCPFlag to
LocalDHCPFlag = 1
Setting Proxy DHCP service to start automatically.
From the Services Control Panel:
Click on Start:
From the command line:
sc config "novell proxy dhcp service" start= auto
[SC] ChangeServiceConfig SUCCESSnet start "novell proxy dhcp service"
The Novell Proxy DHCP Service is starting.
The Novell Proxy DHCP Service started successfully.
Adding DHCP option tag 60
From the command line:
netsh
dhcp server
add optiondef 60 ClassID STRING 0 PXEClient
Next add the new option to the scope; either per scope or globally for the server:
Now you should be set. Test PXE booting from a client machine - and you should be happy.
As a bonus - on multi-NIC or multi-homed machines - you do need to specify the listening IP address in the configuration files for the Preboot services.

Off topic---
Martin, I love your posts and anxiously look forward to them. Would you consider doing a post on the current version of ZCM and what environments you can and can't deploy it in? Also, could you post something (on your blog or this one) about the 10.1 update and how it deploys (or doesn't) through system update?

You will love imaging using

You will love imaging using PXE... Until... You find that it the imaging part of ZCM and Zen7 has poor hardware support that Novell is SLOW to update... Its a pain to have to add your own drivers... I think this comment from Novell customer in the imaging forums that sparked a massive thread says it all
"Novell has managed to make updating of drivers in Zen Imaging so
complicated and frustrating that it is quickly becoming a worthless
product."
Even with a new version of Zen its still rubbish
