Hello Thank you very much for helping me. I have a perfectly good netfilter script that I run from the command line and everything works fine. I would like this script to run when I boot up the computer. I am having a lot of trouble finding quality resources on the net about this. There are great resources for learning how to use netfilter. However, when it comes to startup scripts, all the examples seem to be 25 pages long and incomprehensible or wnat me to completely rewrite the script I already have. Why can't I just tell the computer to run my script instead of the "Let the world in" script it runs at boot? Does anyone have any recommendations, resources or better yet, a good concise example for run level 3? Thank you very much Brian Bunnell --- Outgoing mail is certified Virus Free.
