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