[wplug] ssh with X forwarding not working.

[John Harrold]

I'm trying to ssh from computer A to computer B. Computer A is running
Redhat 9 and computer B is running Debian (sid). When I ssh from A to B I'm
using the following command:

 ssh -X user at B

On B the /etc/ssh/sshd_config file has:

 X11Forwarding yes

Yet, the X11 forwarding is not working giving me the following error when I
try to run xterm:

useer at B:$ xterm
xterm Xt error: Can't open display:


Now I can ssh from A to other computers and X11 forwarding works fine, so I
tend to believe that the problem is a configuration issue on the debian
machine. There is nothing in /etc/hosts.deny, so I don't believe tcp
wrappers are the problem. 

One solution would be to export my display, but since B is on one side of
the firewall and A is on the other, that isn't really an option. Once
again, I can ssh to other computers on the other side of the firewall and
X11 forwarding works fine.
