Remote X applications work just fine, however you do have to make sure that you are configuring your system properly, and that there is no firewall blocking things in the middle in either direction. If you have trouble configuring things, you may wish to seek technical support help on one of the Red Hat and/or XFree86 mailing lists, where someone may be able to provide specific detailed help to the problem you are having. Closing as 'WORKSFORME'
I'm in a LAN without internal proxy or firewall. The same configuration was working between two RedHat9 boxes. Now, I changed one of them by a Fedora 1. The other one is www.cyberfenix.net, you can see. When the client (The Redhat 9 box) sends syn packets to the Xserver (The Fedora box), this answers only with TCP ZeroWindows packets, with the ACK and --->>> RST<<<--- flags set. Then the client tryes with syn packets again, several times and, finally, stops with error. Do you think that this is due a configuration problem? I dont think so.
>Do you think that this is due a configuration problem? I dont >think so. I realize, that in your frustration trying to get your particular problem solved, that you may personally believe that this is not a configuration issue, however I can assure you with 110% certainty that it very much is a configuration issue. Red Hat does not provide technical support via bugzilla, however you may contact your Red Hat technical account manager for support assistance if you have a technical support contract with Red Hat, and they may or may not be able to provide direct one on one technical support to help you configure your systems depending on the level of support that you have purchased. If you do not have a technical support contract with Red Hat, then other options you can explore include the Red Hat and XFree86 mailing lists as described above in my last comment. You may also wish to try searching the web on www.google.com or some other search engine. You can also search existing bug reports for users with similar problems, and see what their solutions were (if any). Nonetheless, this definitely is a technical support issue with respect to the configuration with your system, which may include firewall related problems, xdm/kdm/gdm display manager related problems, or options passed to (or not passed to) the X server at startup. It may also include other problems. Either way, we do not provide technical support in bugzilla, so I am unable to help you directly, other than what I've shared here.
