Forward X11 multiple ssh sessions

doublejoon · 04-19-2007, 02:27 PM

I am trying to ssh to box B from box A (my local box), then ssh to box C from box B.

I want to forward X11 from box C to display on box A (my local box

This is what I tried

Code:

ssh -Y boxB

then

Code:

ssh -Y boxC

I tried to run firefox on boxC to display on boxA

Is this possible?

Yes it is possible

I generally use "ssh -X user@server.example.com app_name" to forward an X application to my desktop from another box

I know about the -X option. Maybe I didn't ask the question clearly enough

I basically want to forward X11 thru a 3rd ssh session.

1) ssh -X or -Y from my box to a box "B",
2) Then ssh -X or -Y from box "B" to box "C"
3) start up a gui app on box "C" and have it display on my box

And I answered that yes it's possible
On every ssh server, check that the $DISPLAY is correctly set to a localhost:10.0 or something that looks similiar.

Hi Doublejoon

I am trying to get this to work, but without any success , getting "gtk warning cannot open display ", do you get the same error.

I can ssh from A to C but cannot get X apps working on the local machine, I have Xserver installed and have X11 forwarding enabled(running cygwin on A and B), linux on the remote machine (C)

If you have any luck, post on the thread

Thanks
