#5 Add port option to check_by_ssh

[Joe Formoso]

We usually have sshd running as a daemon, but we
also have it running on a nonstandard port out of
inetd for administrative purposes. Thus, we had to
make a minor patch to check_by_ssh to take a port
argument, and figured we'd pass it along on the off
chance other Netsaint users might find it useful
