Ok :

On the client side I have the following in my ~/.ssh/config
    Host redoaksw.com
        User        redoaksw
        ForwardX11  yes
        Compression yes
        Protocol    2

When I login I get : 

$ ssh redoaksw.com
redoaksw@redoaksw.com's password:
/usr/X11R6/bin/xauth: not found

You have new mail.

TERM is 'cygwin' on the local machine and the .login switches it to
'xterm' and then exec's bash (which sets the prompt up among other
things).


On the server side /etc/ssh/sshd_config includes :

    X11Forwarding yes
    X11DisplayOffset 10


The funny thing is it is working now for that host (after several
restarts of the X server), but it is no longer working for the Solaris
box at school that used to work just fine.  The config on both sides
is the same (except for hostname).  Actually, once I logged out and
logged back into that FreeBSD box it can no longer connect either.
Weird.

Summary : 
    X forwarding works for the first login to FreeBSD box after
        restarting X server, doesn't work for any subsequent logins.
    X forwarding isn't working at all logging into Solaris, but it
        used to (the last time I used it on that system).
    

BTW, do you know of an image viewing program that would be on a
FreeBSD system?  'xv' 'gimp' and 'eog' are all not found in the PATH.

Thanks,
