Do you have the sshd daemon enabled and running? If it is not running on the host you cannot access ssh to the host. -- Ken Schneider SuSe since Version 5.2, June 1998 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

works for me on 11.4, non-tumbleweed. -- phani. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

there are dozens of things that could be wrong. the sshd_config in /etc/sshd could be set to not allow X forwarding for some reason, if you did an inplace upgrade/overlay install and didn't change/reformat /home, you could have a keys mismatch in ~/.ssh/known_hosts (could nuke or edit the file and try again). those are the most likely things I can think of to try/fix. if you run xclock before you do the ssh command, does it work? this seems like a very odd thing to be doing. ssh -vvvv -X localhost might give some better clues as to what's breaking down. my default install of 11.4 (just downloaded and installed to a vm today) does not have sshd turned on by default, for some reason. -- Even the Magic 8 ball has an opinion on email clients: Outlook not so good. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I think if sshd wasn't running, the session wouldn't start and it wouldn't be possible to type the xclock command :) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It works fine for me. I use it all the time, with both 11.0 and 11.4 as well as many other versions and distros. In fact, I just did it on my work server from home to run xclock and xcalc. I also often use it to run yast2, wireshark and even browsers remotely. It just works. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I have the same problem with 11.4 but worked[s] fine in 11.2 ??? the output of `ssh -vvvv -Y localhost` appears: http://wahoo.no-ip.org/~pat/ssh.vvvv.txt I have had no luck :^( -- (paka)Patrick Shanahan Plainfield, Indiana, USA HOG # US1244711 http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 http://en.opensuse.org openSUSE Community Member Registered Linux User #207535 @ http://linuxcounter.net -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

So, there's some new useful information: it works for some people and it does not for some other. Just have to figure out what differs between the two cases. As far as sshd_config and ssh_config, they're the default, AFAIK. I have run "grep -i forward" on those files. In sshd_config, there is: X11Forwarding yes In ssh_config, there is: ForwardX11Trusted yes BTW, forgot to mention that I can use ssh -X on 11.4 to connect to SLES servers and run graphic apps. So this would lead me to believe there's a problem with the ssh server config on my station. However there's no difference between my own sshd_config and the one on a freshly installed laptop with 11.4. Same goes for ssh_config. Solution: Ok, found the cause: IPv6 was disabled on my 11.4. For some reason that upsets the ssh daemon, and it gave this error in /var/log/messages: error: Failed to allocate internet-domain X11 display socket. or, in DEBUG3 LogLevel: debug3: sock_set_v6only: set socket 8 IPV6_V6ONLY debug2: bind port 6010: Cannot assign requested address debug3: sock_set_v6only: set socket 8 IPV6_V6ONLY debug2: bind port 6011: Cannot assign requested address I have enabled IPv6 (although I don't use it) and ssh -X works now.

tks,
That would explain why it works for me. I use IPv6 and have never had a reason to disable it. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
