Same problem when running `reboot`, which I'd say is even more important for automation. Port 2204 is forwarding to a qemu VM running Utopic, port 2207 is running Vivid:
jderose@jgd-kudp1:~$ ssh root@localhost -p 2204 reboot jderose@jgd-kudp1:~$ echo $? 0 jderose@jgd-kudp1:~$ ssh root@localhost -p 2207 reboot Connection to localhost closed by remote host. jderose@jgd-kudp1:~$ echo $? 255 jderose@jgd-kudp1:~$ -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1429938 Title: stopping ssh.service closes existing ssh connections To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1429938/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
