Cant get x apps to work on ssh?

Cant get x apps to work on ssh?

Post by Brian Wagene » Tue, 05 Dec 2000 11:07:23

I am trying to get ssh to work with x apps, but even though x forwarding is
on, it doesn't work.  Below is a debug session of me trying to connect back
to the same machine, so hopefully you can help me.

1. ssh -R from work to home and ssh from home to work

While I am at work I run:

While I am at home I run:

So I am now working from home.  The problem is that $DISPLAY is not
set.  This doesn't pose a problem yet because X forwarding is still
sending Xwindows to my home display.  The issue is: after I ssh to
work and then ssh to another network server the $DISPLAY variable is
set to the display of the original machine I ssh'd to and Xwindows are
now sent to it rather than home.

I don't know why $DISPLAY is not set on the original ssh but all I
want is for the windows from the second ssh'd to server to end up at
home.  Is the first problem the cause of the second?  More
importantly, how do I solve the second problem.

Thanks for any help.
