Fedora Core 5 enabling X11 port 6000

By default, a new Fedora Core 5 installation has the X11 server set up for "-nolisten tcp", which prohibits incoming X11 displays from other workstations on port 6000. I would like to turn on X11 port 6000 to allow incoming X11 displays.

Modifying the /etc/X11/xdm/kdmrc file to comment out the entries for ServerArgsLocal and ServerArgsRemote is not enough. After a reboot
that didnt change the situation. I tried setting them to "-listen tcp" with no luck. I cant find any man pages on the topic. Can anyone tell me exactly how to turn on listening on port 6000 on Fedora Core 5?

I eventually found that gdmsetup is used to configure the X11 server. On the Security Tab, you need to turn off the "Deny TCP connections" option. Then you add port 6000 to the firewall, reboot and you can receive incoming X11 displays.
