Environment
Novell ZENworks Configuration Management 11.3 Appliance
Imaging
Situation
Deployed the ZENworks 11.3 virtual appliance
The novell-proxydhcp service is started
PXE booting fails with one of the following errors:
TFTP.....
PXE-E32: TFTP open timeout
PXE-E53: No boot filename received
The novell-proxydhcp service is started
PXE booting fails with one of the following errors:
TFTP.....
PXE-E32: TFTP open timeout
PXE-E53: No boot filename received
Resolution
Disable the firewall on the ZENworks Appliance:
- Right click the desktop and select: Open in Terminal
- Enter the command: yast2
- Double click: Services and Security > Firewall
- Click: Stop Firewall Now
- Click: Disable Firewall Automatic Starting
- Click: Next > Finish
Cause
The firewall is started by default on the ZENworks Appliance. This
prevents the necessary communication for the PXE process even after
the novell-proxydhcp service has
been started.
Additional Information
The operating system firewall should not be running when using PXE
imaging. Please refer to the following note from TCP and UDP Ports Used by ZENworks Primary
Servers :
UDP Port 13331 - "Used by the zmgpreboot policy, but will not work across firewall because it opens random UDP port for each PXE device."
