I can use one machine to start an X11 forwarded client on another. I did this to start gnome-terminal on a Ubuntu Server 16.04 from a Kubuntu 16.04 desktop by using
ssh -Y -f 192.168.0.89 gnome-terminal This works. Then I look at that gnome-terminal's environment and DISPLAY and SSH_CLIENT variables are properly set: DISPLAY=localhost:10.0 SSH_CLIENT=192.168.0.215 38634 22 Then I look for listeners on TCP port #6010 as is implied by the above DISPLAY envar: $ netstat -anl4 Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN tcp 0 0 192.168.0.84:22 192.168.0.215:38542 ESTABLISHED tcp 0 0 192.168.0.84:22 192.168.0.215:36110 ESTABLISHED udp 0 0 0.0.0.0:68 0.0.0.0:* No such listener. I did this same sort of ssh connection from my desktop Kubuntu to a Raspberry Pi running Raspbian and the rpi has a listener as I would expect it to. I believe this lack of a listener for the ssh on the remote machine to allow X11 clients to connect back to the server through "screen :10" is what is missing. In in /etc/ssh/sshd_config on the target Ubuntu 16.04 server machine I have this for X11 forwarding configuration: $ cat /etc/ssh/sshd_config | grep -i x11 X11Forwarding yes X11DisplayOffset 10 I have always been able to get this to work with previous Ubuntu releases (14.04, the 15.x series, etc.). This is something specific to changes in Xenial. It looks like the release notes (https://launchpad.net/ubuntu/xenial/+source/openssh/+changelog) include some changes for this area of ssh. Maybe the fix for this (http://www.openssh.com/txt/x11fwd.adv) partially borked ssh's X11 forwarding mechanism? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to evince in Ubuntu. https://bugs.launchpad.net/bugs/1573300 Title: ssh -X X11 forwarding doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/evince/+bug/1573300/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
