Hi, list,
I think we're missing this information (about --parachute, --pid-file,
--parachute and --panic-script) in the user guide, don't we?
Below is the possible init.d script which we could add to contrib:
#!/bin/sh
MBUNI=/home/menulis/mbuni
BINDIR=$MBUNI/bin
PIDFILES=$MBUNI/run
CONF=$MBUNI/etc/mmsc.conf
MP=mmsproxy
MR=mmsrelay
test -x $BINDIR/$MP && test -x $BINDIR/$MR || exit 0
case "$1" in
start)
echo -n "Starting MMSC: mmsproxy"
$BINDIR/$MP --daemonize --parachute --pid-file $PIDFILES/$MP.pid -- $CONF
sleep 1
echo -n " mmsrelay"
$BINDIR/$MR --daemonize --parachute --pid-file $PIDFILES/$MR.pid -- $CONF
echo "."
;;
stop)
echo -n "Stopping MMSC: mmsrelay"
kill `cat $PIDFILES/$MR.pid`
sleep 1
echo -n " mmsproxy"
kill `cat $PIDFILES/$MP.pid`
echo "."
;;
reload)
# We don't have support for this yet.
exit 1
;;
restart|force-reload)
$0 stop
sleep 1
$0 start
;;
*)
echo "Usage: $0 {start|stop|reload|restart|force-reload}"
exit 1
esac
exit 0

Hi,
why always go a complicated way?? Did you read userguide?? Just use
something like this:
bearerbox --daemonize --parachute
smsbox --daemonize --parachute
This will start bearerbox and smsboxc as daemon and also start parachute
process (watcher). If box then crashed parachute process will restart
child process automatically.
Thanks,
Alex
