I have been trying to fix an issue that I have with my RedHat 9 system. The system is connected via cable modem to RoadRunner, so it receives a DHCP IP. The DHCP client also provides a hostname. The hostname is NOT a FQDN so Gnome/GDM will not allow me to login when the system is set to the hostname provided by the DHCP client.
I am able to log in into KDE fine, so I am not dead in the water. I have tried a few different things. First I applied a startup script that seemed to change the hostname to the FQDN of the assigned DHCP IP. This failed to correct the problem with Gnome/GDM. Then I put a "local" HOSTNAME entry in one of the /etc/sysconfig configuration files, and added the host to /etc/hosts. So the hostname is of my choosing, but of course it is not a FQDN. At least this method allows Apache to run, but I can not login via Gnome/GDM. Google searches found this same problem many times, but I was unable to find a resolution. Any suggestions? Steve A.
