[Bug 497781] [NEW] sshd stop on two SIGHUP
Public bug reported: When you send two SIGHUP to sshd (to reload it configuration), sshd simply die. How to reproduce: 1)start an sshd server if you do killall -s SIGHUP sshd. The server restart successfully. 2) To kill sshd with SIGHUP, run killall -s SIGHUP sshd killall -s SIGHUP sshd i.e. run two killall -s SIGHUP sshd at the same time. 3) # ps waux | grep sshd root 19265 0.0 0.0 3352 820 pts/10 S+ 15:42 0:00 grep sshd No sshd running :( I think it's because the second SIGHUP happend before sshd finished his startup. Their is not problem running several killall -s SIGHUP sshd we a little delay (like the time to press up arrow and enter). But two SIGHUP at the same time cause sshd to die nearly everytime. This is an issues because afaik SIGHUP is sent by networking script (ifup ?) when an interface have an IP. On a server with 3 static IP, the sshd process get killed this way. No sshd, not possible to do an ssh on that server. Rebooted the server and everything get fine. ** Affects: openssh (Ubuntu) Importance: Undecided Status: New -- sshd stop on two SIGHUP https://bugs.launchpad.net/bugs/497781 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. -- 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
