The only problem with this ploy, of course, is that myself (along with
many other people) take great joy in shutting off RPC whenever possible.
So, yeah, portmon is a great "substitute" or workaround (after all,
we're really only concerned that particular services are responding at
reasonable levels more than anything else).

Along the same lines:

     Anyone come up with an SSH monitor, perhaps?  Yeah, portmon works
here but you can only tell that it's answering and that it's returning
the right identification string; but what happens if it's handoff to
login doesn't work right?  Anyone take it that far (ie. no login
prompt) yet?
