How to run a script at system startup?
 

I have a script file (for starting a service) that I would like the system to run when it boots. What should I do to achieve that?

My Linux box is Debian Sarge.

Thank you!

Here's my notes on using my firewall script for Debian based systems like Knoppix or Feather:

Save the firewall script as /etc/init.d/firewall.

Important: Set the permissions for root to read, write and exec. Also, read and exec for group and others.

Something like chmod 755 /etc/init.d/firewall aught to do it.

Type: update-rc.d firewall defaults 99
