Okay Alan, I've had 3 or 4 folks over the last 36 hours claim that X is
its own forwarding agent, why am I even using ssh? saying I'm not
needing ssh at all.
So, where can I find the definitive tut on doing this because our
attempts are failing? What I was able to find on the xorg web pages
last night was up to 3 major versions out of date. I need a tut that
deals with X11R7 and up. Is there such a thing? My google-fu is
Cheers, Gene Heskett
