[PLUG] X Forwarding Problem

[Casey Bralla <MailList@NerdWorld.org>]

I'm trying to run remote X applications, something I have done lots of times 
in the distant past.  I discovered that ssh has added a few more security 
features, which I think I have delt with.  Here is an example of the error 
I'm getting:

RemoteComputer ~ # xclock
Error: Can't open display:




So ssh appears to be setting up port forwarding properly.  I have added the 
line "xhost +" to my .xinitrc to allow foreign screens to be used.  I don't 
see anything obvious in the logs



Anybody have any ideas where to look for a solution?
