#
# Basically, this script check for each process in the PROCS directive
# and sends an email if the process has been down for 5 min to $EMAIL.  It 
# sends a repeat page every 30 minutes.
#
#
# Note, if you remove a process from $PROCS, please ensure all /tmp/.*$PROC*
# files are removed.

PROCS="syslogd klogd sshd inetd smbd nmbd named dhcpd mysqld nfsd master"
