Startup services
 

The distro I am using has an Xinetd and a bunch of rc.d files. I am trying to get a program to run at startup but I am not sure how to start. Could some one point me in a good direction so I can figure out how to make programs run on startup?

Thanks

:smash:

Had to use the gif!

add whatever file you want to /etc/rc.local and it will load on startup. if you're talkign abuot services and similar, you want to enable them properly using sysvinit or somethign like that

I thought thats how you do with the old init.d file not the xinit.d. I do not have an rc.local but rather
rc0.d
rc1.d
rc2.d
rc3.d
rc4.d
rc5.d
rc6.d

I could be completely wrong but I thought with the intro of xinitd.d everything changed?

Either way thanks for replying

Ahh ok I have it all figured out.

Anybody who needs anytype of help on runlevels and how linux starts up programs on boot should read this, its great!

I have been searching all day and this was a gold mine!

Quoted from the above mentioned article:

"Links beginning with a capital "S" are to be started, whenever the system is entering the given runlevel.

"Links beginning with a capital "K" are to be stopped whenever leaving that runlevel."

Now, the following is my /etc/init.d/rc file, script used to start/stop the services as needed:

********** START /etc/init.d/rc ************************
#! /bin/sh
#
# rc This file is responsible for starting/stopping
# services when the runlevel changes.
#
# Optimization feature:
# A startup script is _not_ run when the service was
# running in the previous runlevel and it wasn't stopped
# in the runlevel transition (most Debian services don't
# have K?? links in rc{1,2,3,4,5} )

***********************end***********************

Now, I'm aware my scripting is far from the best but like I understand the script, it'll run the kill scripts in the *new* runlevel? This seems wrong for me, as I understood it like the article said, and then I tried it that way - and for the first time in dunno how long - my trusted debian linux crashed on me when switching levels.

Any/all help *very* welcome.

PLEASE PLEASE PLEASE do NOT drag up long dead threads. thanks.
