[NTLUG:Discuss] X over SSH again...

[Cameron, Thomas]

Hrm...

I *am* confused.  If I'm on host foo and I ssh into the host bar, when I run "env | grep DISPLAY," it says foo:0.0.  In other words, $DISPLAY is set to the machine I'm sitting in front of, not the host I'm ssh'ing into.

What does /etc/hosts look like?  Are you using dhcp to get your ip address?
