Red Hat Bugzilla – Bug 199296
Need documentatio on how to make X11 server listen to port 6000 for incoming X11 displays

Description of problem: Refer to bug #197964. 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. Could you tell me exactly how you turned on listening on your workstation? Version-Release number of selected component (if applicable): 2.6.15-1.2054_FC5 How reproducible: On demamd, this is the default X11 behaviour for a new Fedora Core 5 installation. Steps to Reproduce: 1. Refer to bug #197964. 2. 3. Actual results: X11 is not listening to port 6000. There are no man pages or other documetation to explain how to actually get it to work. Expected results: Allow incoming X11 displays from other workstations. Additional info:
This is already reasonably documented in the manpages that accompany the Xorg X server, and xdm. If you find the X.Org documentation inadequate however, you can file a documentation enhancement request to X.Org if you like at http://bugs.freedesktop.org If you're using GNOME or KDE, you'll need to consult their documentation instead as GDM and KDM have their own configuration files/syntax, and that is not part of the X.Org X11 implementation. If there are deficiencies in the GNOME/KDE documentation, you may want to direct a request to the GNOME or KDE projects as well. There's nothing inherently operating system distribution specific about how this works as far as the X.Org bits go - we ship it with the X.Org defaults essentially. If you're asking for Fedora specific documentation on how to do this, you're best discussing it on the fedora-devel mailing list and possibly contributing something to the Fedoraproject Wiki (or encouraging others to assist perhaps). Closing as NOTABUG however, as I do not find the X.Org documentation on this inadequate.
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.
