Soren, I just now re-read your original description, and I see this: debug1: Killed by signal 15.
That suggests that your *client* ssh is being killed. The sshd debug supports that: debug3: fd 9 is O_NONBLOCK debug1: Setting controlling tty using TIOCSCTTY. Received disconnect from 10.115.0.105: 11: disconnected by user Is it possible there is something on your local machine killing ssh's for some reason? You said they get killed at the same exact time.. maybe a cron job? Also re the pid file being present but ssh in stop/waiting.. if that pid is running sshd, then you have hit bug #531912 by accidentally using /etc/init.d/ssh instead of the upstart start/stop commands. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/716310 Title: ssh connections disconnects automatically -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
