1.4.6 PXE Booting Fails Due to Incorrect Host Name Configuration

If the Spacewalk server was installed without a fully-qualified domain name (FQDN), or a name that cannot be resolved in DNS, Spacewalk creates invalid PXE boot configuration files.

You can validate that Cobbler is configured correctly by checking that the IP address used in the ks= parameter in the /var/lib/tftpboot/pxelinux.cfg/default file is correct.

To reconfigure a Spacewalk server after installation:

  1. Edit the /etc/cobbler/settings file and change all instances of incorrect host names, such as localhost.localdomain.

  2. Restart Spacewalk by running spacewalk-service restart.

  3. Resynchronise Cobbler by running cobbler sync.
