I answered a very similar question just a post or 2 before yours.
There are various places and ways a program can get started at boot, but the
basics are:
/etc/rc
/etc/rc2
/etc/rc.d/*/*
/etc/rc2.d/*
/etc/inittab
try this - this looks at file names:
find /etc/rc* /etc/init* -name '*ctstart*'
and this - this looks inside the files:
find /etc/rc* /etc/init* -depth |xargs grep -l ctstart
It might be started indirectly though. Maybe some script reads a config file
which could be located anywhere on the system.
You just have to look for anything that isn't stock.
Try searching with the same commands above, but instead of "ctstart", try
other things like your initials, or some former emplyees initials, your
companies name, you customers companies name, anything you think might found
in comments in scripts or used as filenames or parts of filenames, etc.
Ultimately, the boot process starts with init, which reads /etc/inittab,
which tells it to start reading the rc scripts, which go on to read all
maner of things.
You could just drop back & punt and do it the brute force way. read
/etc/inittab and follow the same trail the system follows.
It's a pain but if you really can't find it, then that is the most "stop
guessing" garunteed approach.
any of these lines are suspect, and go from there.
awk -F : '!/^#/{if($3!="off") print $0}' /etc/inittab
In english that's any line that doesn't start with # and whose 3rd field is
anything but "off", is a possible starting point that might lead to the
script that starts your app.
Thy are all the lines that start anything at all.
also,
man init
man rc
