Can't open X apps when ssh'd in?

BrianK · 12-01-2005, 11:06 PM

On my old computer running RH7.3, if I ssh into my file server, I can open an emacs session, no problem. On my new computer running Suse9.3, I can't seem to get it to work. I've tried setting the DISPLAY env var to <my_ip>:0.0 once I've logged into the file server, but still only get the non-x version of emacs. I know the server is forwarding X because it works on my old machine.

What should I be doing that I'm not?

Thanks.

Instead of manually setting your DISPLAY variable, why not try ssh with the -X switch?

Code:

ssh -X user@ipaddress

If you are sure X11 Forwarding is enabled, then maybe the above command will work...

or -Y with modern versions of OpenSSH

that a standard command which usually work without problems.

just change on your server in /etc/ssh/sshd_config the "X11Forwarding" to "yes".
and after you login over ssh, do not change DISPLAY because it is already set.

I am working pretty often this way.

Both of those options worked. I didn't know about the -X option, which worked fine. However, by changing X11 forwarding to "yes" on the client machine (in my case, the Sus9.3 box), X finally started going through... I thought that setting only mattered on the server.
... assuming the thing I'm connecting to is the server and the thing I'm connecting from is the client.

Thanks!
