3     # Script to check that ihost is still running, and restart if necessary.

5     # You probably want to add this to a cronjob, say every 10 minutes:
6     # 0,10,20,30,40,50 * * * * /path/to/ihostchk.sh
7     # And if you find yourself getting e-mails, use the following instead:
8     # 0,10,20,30,40,50 * * * * /path/to/ihostchk.sh >/dev/null 2>&1
9     # NOTE: e-mails should only be sent if an error occurs, so the former is
10     # the best choice for a cronjob.
