Re: More SSH Fun (X11 forwarding)



Hi Vineet, 

I appreciate the help, but I know that setting the DISPLAY doesn't work
either. 

I need to know what DOES work, or if this is a bug.

How did you get X11 working on Debian running OpenSSH 3.4p1? Did it
just magically work for you? Did you have to set something?
