Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I've used sshd on a number of different operating systems, but only with Fedora have I had an X forwarding issues. I've configured the sshd_config file to allow for X forwarding. Whenever I try to run a graphical program on my Fedora server, it either just doesn't work or it says something like "could not initialize the graphical user interface".
I've looked at everything in the sshd_config file, and I can't seem to find the problem.
What is the output of "echo $DISPLAY" on your local computer? What is the output of "echo $DISPLAY" on the remote computer when you log in through SSH? Does your problem occur with only some programs, or all X programs?
Don't have a solution to your problem, but I just ssh'd into my FC5 box from SuSE 10.1 with X forwarding and ran a couple apps (tvtime blew up BTW... was worth a try, lol.) So it works for me. I have firewall and selinux disabled though, if that makes any difference.
I've configured the sshd_config file to allow for X forwarding.
Well, if it seems to be working for everyone else (even with firewall and selinux enabled) then it's likely something you did to the sshd_config file, IMHO. I didn't have to do anything to it for X forwarding to work.
Well, the first time I tried to get X working, I was using the original configuration. By saying I configured it to allow X forwarding, I really meant that the config file said X forwarding was enabled.
