A start and stop script for Linux already comes with ASSP and in most
configurations (single ASSP on 1 server) they are sufficient.
On my setup I have a watchdog for all the ASSP processes I'm running and
they rely on the start and stop script.
In the past I have had some ASSP's running simultaneously and after using
these scripts I've never had that again.
Please use them if you can make them of use:
/opt/ASSP/start
#!/bin/bash
#
# 'start' - Shell script to start ASSP
