Hey Group,
(The search engine seems to be down so I looked manually over
the past few month and couldn't find anything).
I just reinstalled freebsd in a lab that I support and X11
forwarding from ssh doesn't seem to work anymore. The client and
servers are 4.4-RELEASE and X is XFree86-4.1.0_10 built out of the
ports about a week or so ago. Each machine has the exact same
version.
When I try to do X11 forwarding this is what I get (trimmed
verbose output appended) You can see that I have X11 forwarding enable
on both the ssh client and server.
I now have some very students :(
Any help would be greatly appreciated.
