Hi Kim,

Yes it is the pix. We had this issue years ago. I can't remember exactly what
solved the problem.

The issue is that the Pix will remove the xlate entry after an hour or 2.( if
you want to remain connected without typing for 2 hours instead of 30
minutes).

Or enable keepalives in sshd.

cheers

Re: ssh server behind pix timeout [In reply to]

timeout xlate hh:mm:ss
timeout conn hh:mm:ss

The xlate timeout should always be longer than the connection timeout.
I usually go for 4:00:00 for the xlate and 3:00:00 for the conn. I seem
to remember some recent PIX's having a timeout value of 00:05:00 for one
of those two.
