[Bug 716310] Re: ssh connections disconnects automatically
Another observation : running this command : watch -n 1 date on two difference ssh-conntection to two different servers continously show the running date and time. The time is of cause offset by some amount of seconds (20 in my case). Based on that offset I can see that those two connections are dropped at the exact same time. I have also tried running sshd on an alternative port. I will post the log after this. -- 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/716310 Title: ssh connections disconnects automatically -- 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

[Bug 716310] Re: ssh connections disconnects automatically
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 Server Team, which is subscribed to openssh in ubuntu. https://bugs.launchpad.net/bugs/716310 Title: ssh connections disconnects automatically -- 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
