SSH X11 Forwarding...

[Wizard]

While we're discussing SSH, I'm trying to implement X11 Fowarding on a
Solaris 9 box, but can't seem to get it working. I can set my display under
telnet and X is redirected to my SGI box, but when I login using SSH, the
server errors with something like "Can't find display: " and there is no
display set. 1.) How do I set the display (I would guess 'setenv DISPLAY
ip:disp', as in telnet), and more importantly, 2.) What do I set it to
(obviously the IP won't work)?
Thanks,
Grant M.
