OK, I think I am losing or maybe have lost my mind. A couple days ago
Bruce gave me a long post with detailed instructions on how to work
through my remote display problem. Some how, some way, I have managed to
lost it before I got around to doing it. I have been up on the archive and
have searched for the "remote display" subject. I see a number of posts
from different people on a lot of different subjects from this month but
not my posts or any of the reply posts from Bruce, Pol or anyone else. Is
there a time delay before the posts go to archive?
It should be in the archive, but I don't see it either.
Bruce, If you would be so kind, could you please resend that detailed set
of instruction?
Here you go.
First, the server has to support X. In /etc/ssh/sshd_config you should have:
X11Forwarding yes
#X11DisplayOffset 10
X11UseLocalhost no
XAuthLocation /opt/xorg/bin/xauth (if Xorg is installed in /opt)
If a change is needed, reload sshd. (/etc/init.d/sshd reload)
On the client side:
~/.ssh/config
Host 192.168.1.22 (ip of remote or name is in /etc/hosts)
ForwardX11Trusted yes
ForwardX11 yes
========
If you run 'ssh -v remote', you should see
debug1: Requesting X11 forwarding with authentication spoofing.
Do NOT change DISPLAY. You do not need the xhost command either. The
sever will set DISPLAY to
remote:10.0
If you have multiple sessions, it will change to remote:11.0, 12, 13, etc.
That's what the default X11DisplayOffset above does.
Then just run something like xclock and it should come up on your client.
Note that gtk+3 based apps will not display properly. They don't look up
settings on the remote system and look horrible, although they do run. I
think they need something on the local system, but I have yet to figure
that out.
You can also troubleshoot the sshd daemon. You have to run on the remote
system '/usr/sbin/sshd -d' and it puts debug info to the screen and the
daemon does not go to the background. That's how I figured out that
XAuthLocation was needed.
