"ps axuf" should make it easy to associate ssh server processes to the programs that you are using over ssh and "netstat -alpn" should tell you which tcp ports these server processes are talking to. If you then run "netstat -alpn" on the client side you can figure out which client uses the port associated with the "frozen" connection. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
[debian] ssh hangs
a long time ago i used to experience frequent hangs with ssh connections, when using that infamous dropbear. after i while i got fed up and replaced that crippled thing with a full good sshd, which worked well until a few weeks ago. but with an upgrade of sshd a few weeks ago the exact same issue was introduced again, after a few lines of output the ssh shell freezes and there's nothing to be done excpet killing -- and that's not that easy since i usually have several connections open and there's no easy way to determine which one is the frozen one. so, 1.5 questions: - what happens? i never found any log entries shedding light. does anyone else experience that? - is there a way to make ssh connections easily distinguishable with ps or so? ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
