How I do run gnome app and let it run via SSH even after SSH closed

remote accessssh

I found that, exporting DISPLAY=:0.0 and starting a gnome app (xclock) would run on remote machine. The issue , when i log out of SSH, the xclock closes on the remote machine. I wanted it run there until i quit or kill it from remote machine itself. Is there way achieve it ?.

If I understand your question correctly, the X Server is on the remote machine. Then you just need to filter the HUP signal with nohup.

Another nice command is screen which lets you reconnect to older sessions. Its worth a look when you often use SSH.

I found the problem. Setting DISPLAY manually to localhost:0 is not working, because the XServer does not listen to TCP connections (default Ubuntu 10.04 configuration).

However, setting

export DISPLAY=:0

does the trick.

X over SSH and xauth not working

Your error message "Can't open display: 192.168.0.76:0.0" doesn't sound like SSH X11 forwarding is in use. Instead, programs on the remote host are trying to connect directly to C1, which won't work for quite a few reasons (Xorg does not listen for TCP connections by default; your firewall blocks them; the Xauth data was not sent correctly...) If X11 forwarding was in effect, then $DISPLAY would point back at the same machine (localhost), and the display number would start at :10.

First, check the $DISPLAY value on C1, and make sure clients on C1 can connect to the X server.

Then retry the connection C1→S1 using ssh -X -v -v S1 and make sure there are no error messages regarding X11 forwarding; it might be disabled on the server. (If you connect with PuTTY, then Ctrl+rightclick the console and select "Event Log".)

To see the server logs, add LogLevel DEBUG2 to /etc/ssh/sshd_config and restart sshd.
