ssh timeout

[Howard, Chris]

You can kill a child process after a certain time
has elapsed.

So, you would have a parent shell script start
up the ssh script and put it in the background (&).
Then call sleep for some
number of seconds.  When it wakes up if the
child is still running ('kill -0 $pid')
then you send it a kill signal ('kill -9 $pid').
Use a file in /tmp for the child to pass back results
to the parent process if it succeeds.

Or, I think you could use a timeout signal
in a perl script.

Or, I think you could have the remote machine
use ssh to put its information  onto a central
monitoring machine periodically using cron or
similar.  Then your monitoring program would
just look at that centralized information and
not do an ssh at all.
