[Fink-users] ssh/ForwardX11/DISPLAY problem
I just upgraded my office machine to Jaguar and am no longer able to run X-apps from home due to X-forwarding problems. I've set ForwardX11 to yes in both /etc/ssh_config and (after installing openssh from fink) in /sw/etc/ssh/ssh_config. I've also tried logging in with ssh -X [EMAIL PROTECTED] However, echo $DISPLAY on my work machine gives the message: DISPLAY: undefined variable I'm stumped. And now I'm going back to the office to finish up some things. :-( --- This sf.net email is sponsored by: See the NEW Palm Tungsten T handheld.

in /sw/etc/ssh/sshd_config and /etc/sshd_config X11Forwarding yes all other values as installed. Another possible culprit (I need to check) are the MATLAB-installed changes to X11R6 under Jaguar. I did a re-install of X11R6 while at work tonight; I'll try it out again when I get home to see if things behave. After I get some sleep, that is.

Thanks. Neither than nor my Matlab X11R6 patch idea seemed to have any effect.

Welcome to Darwin!
So it looks like it's trying to set up X11 forwarding, but the DISPLAY
variable remains unset.
I wonder if some parameter in the Jaguar network/sharing preferences may
be to blame. I can
remote log in, but the DISPLAY variable is still missing.

Now that I read your message, I think my fix isn't valid. You also need
to
make sure you restart sshd after editing the file (or 'kill -HUP' it to
have it re-read the config file) and then do some hunting by starting
ssh
with some -v's like: ssh -v -v -v [EMAIL PROTECTED]

Re: [Fink-users] ssh/ForwardX11/DISPLAY problem
Stupid questions are often the most valuable; yes, I did check that DISPLAY was set on my home machine (I can never get "client" and "Server" straight in my head, but I think this is the server, the physical display, and DISPLAY is set to :0 [localhost:~] hodelas% echo $DISPLAY :0 [localhost:~] hodelas% ssh $cube [EMAIL PROTECTED]'s password: Last login: Sun Nov 3 15:32:43 2002 from adsl-157-133-20 Welcome to Darwin!

.cshrc only souces /sw/bin/init.csh, so I'm at a loss of where else to
look.

And now that I think about it, doesn't ssh check your environment and
execute your shell commands? Make sure something else isn't hosing your
DISPLAY.

I'll do a system reboot later once I clear out some weekend batch jobs. I'm guessing this is the culprit. Thanks very much to you, M. Costabel, and M.
