This is very nice. Thanks for the good options!

Excellent summary of useful Linux commands for checking services! That was exactly what I needed for my own problem.

vi /etc/services
vi /etc/rc.d/
vi /etc/init.d/
vi /path/to/service-startup-scripts/can-be/elsewhere/too

Thanks, already know all that stuff though, I've spent some twenty years on Unix, but some of the new linux specific commands are new to me.
