When you log in on the server, what are the XAUTHORITY and DISPLAY environment
variables set to?  What output do you get if you run ssh with the "-v" option
when logging in?

Comment 2 Mike A. Harris 2002-05-30 03:14:11 UTC

ssh X11 forwarding works for me ok.  I'd say this bug is a transient issue
of some sort or local config problem.

Comment 3 Alexander Kanevskiy 2002-05-30 12:45:32 UTC

By default on new openssh in sshd_config X11UseLocalhost set to yes. 
So, then app want connect - it try connect to $hostname (usually to real
ip on ethernet/etc...), but sshd bind to localhost:7xxx port.
