I reinstalled my fileserver machine with FC2. Previously, on the RH9 install, I had it set up so that I could ssh onto another machine in my house, type the name of a graphical program, such as 'kmail&', and the GUI would appear automatically on my local screen. Now that I have re-installed, it won't work.

I did a xhost +ip1, but after doing that, it still won't work (Can't open display error). I used to be able to do this without any changes on the remote box, I didn't even have to set up the DISPLAY variable at all. It just worked tunneling the app over SSH.

Any idea what I might have done to allow this behavior?

I looked at my /etc/ssh/ssh_config, and have this:

Host *
ForwardX11 yes

as the options not commented out.

Thanks,

hmm, but I think it's just a command-line argument in ssh? so it should go like this:

[somebody@somewhere]$ ssh -X someplace
somebody@someplace's password:
[somebody@someplace]$ kmail &

and that's it. so just start ssh with the -X argument (big X means "enable X forwarding", small x means "disable X forwarding" I think) and you should be fine....

that's, at least, what

man ssh

has to say about this.
