X Forwarding Problem with ssh
Posted by lane
Recently I ssh’d into one of my servers using the command ’ssh -X hostname’ from the client. I then tried to launch an X11 application but received the error:
Gtk-WARNING **: cannot open display:
I then found the DISPLAY environment variable was blank. A little searching around and I found that the I needed the xauth program installed. A
yum install xorg-x11-xauth
on the server did the trick. Now when I ssh in using the -X option, X11 applications run fine.
