Adding an application to auto-start on boot-time
 

Recently I installed Squid Proxy server. And I'm just SICK of starting it myself so my brother can surf the web.

How do I add that script?

Depends on your distribution. MOST *cough*notslackware*cough* use a simple system for controlling what gets started. Startup scripts start in /etc/init.d (/etc/rc.d/init.d/ for redhat). Then, depending on your runlevel # (see /etc/inittab), you create a symlink from /etc/init.d/scriptname to /etc/rc#.d/SXXscriptname where XX is a number that controls what order things are started in (be sure it starts after your network config!) (thats in /etc/rc.d/rc#.d/ on redhat)

Squid should have come with a script, if not, there is usually a skeleton script lying around in that init.d directory, or you can gut someone else's script and use that. Make sure the script is executable.

On most distros there's "chkconfig" which adds the script to a given runlevel for you. Also, most distros have a graphical chkconfig-like front-end where you can simply click something like "Enable" next to the service you which to have run at boot time.

I put it in /etc/rc.d/rc.local just make sure you put & after the path/command so it does it in the background. Took me a while to figure this out.

I found info on a message board about getting teamspeak and Q3 to work at the same time. I was told to add two lines to my start up script but I am not sure which script that is can anyone point me in the right direction? I am using Fedora core.
