SSH Tunneling of X protocol from noninteractive session

Mihai Osian

I cannot use -X or -Y option, because I have to run *noninteractivelly* from computer C to display M. I plan to sumbmit script like

export DISPLAY=C:1 xterm -e gdb myexecutable

while there is a open tunnel from C:6001 to M:6000.

It is because C is a 50 nodes cluster and I need to run debuging job in a parallel enviroment. I don't sit on front of the C, but at terminal M, it is 1000 km away 700 miles. Normally, you have to prepare script on C, submit the script using PBS system and when the cluster is free usually imediatelly the job starts. When the job starts, I would like it to open terminal with the debugger on my computer M and I can start to debug interactivelly. I was doing that, but there is a firewall now and I don't know how to work it out.

flag.

It should be listening. The X is running withusr-X11R6-bin-X vt7 -authvar-lib-xdm-authdir-authfiles-A:0-qCOhba I can go to another machine, point display to M:0.0 and open a terminal. How can I recognise on which port does it listen (it should be 6000 normally). netstat -a gives me this line: tcp 0 0 *:x11 *:* LISTEN

Any idea?
