\_ make a crontab entry:

Note that this crontab entry and 'ping ... -i30' are *not* the same
'30'.  crontab means 30 minutes, ping means 30 seconds.

In the FWIW department, I've before added a happy little sound wrapper
to the ping output...made it easy to tell when the flaky DSL of the
company of the time would come back to life.  :-)
