   I have a script which runs fping on a bunch of servers and writes
   a timestamp for any host that answers.  It's run every minute from
   cron on our loghost.  Another script watches the results and sends
   me an IM if any of my boxes fails to respond for 3 minutes.

   I can put up a tarball if anyone's interested.
