Hello,

I had that case on SLES11. I installed "xorg-x11-xauth" via yast, afterwards I could do a ssh -X -l root <remote> and then Display forwarding worked for me. I dont know how this behaves on 10.3.

There is no xorg-x11-xauth package on the 10.3. Too bad. Perhaps there is still some missing package. I so did not expect this. Timing for this could not be worse...

I have now verified that a working source computer (the machine I ssh from) fails against the host I want to run an X app from. When the ssh connection is made, the two machines must, it seems, agree on something before the ssh-from machine will set up the X port. It seems that is failing. So, perhaps there is something mussing on the system I ssh into that makes this not work. It is a rather scaled-down system. ssh is of course installed. Is there anything else that needs to be installed on the ssh destination for X forwarding to work?

...

Best regards,

Johannes Müller-Lahn

I am trying to run a remote X application on a 10.3 system. There is a problem connecting to the display from the system I ssh into. I do this all the time, and usually there is no problem. But I have a system that is not working and I do not know why. Perhaps I have forgotten a step in 10.3.

I have edited /etc/ssh/ssh_config on the system I ssh from, setting:

Host * ForwardAgent yes ForwardX11 yes ForwardX11Trusted yes

There is nothing in ~/.ssh/ that overrides this.

When I connect to another system with ssh, I would expect the DISPLAY variable to be something like localhost:11.0 But that is not the case. In addition, I would expect to see a port listener on the system I connect from, in this case on port 6011. There is no such thing.

I also tried the older method of setting DISPLAY on the remote system to refer to the system I want the app to display on. This does not work either. I ran xhost + on that system. Once again, I would expect to see a port listener on port 6000 that can be connected to from other than localhost. I do not see this.

Could there be something on the system I am ssh-ing to that keeps the DISPLAY variable from being set?

I am in a real bind as I did not expect this problem and need to run the app urgently! Any suggestions are appreciated!
