Firewall Start at Boot

canuck_dude · 02-01-2007, 12:25 AM

Hey,

I made a firewall using iptables and have it in a shell script. How do I make the script execute at boot time so it gets automatically setup? I tried putting it in the /etc/rc.d/rc.local file but it always crashes my computer when I restart. I'm using Fedora Core 6.

First you should test the script before including it any start up scripts. Use your favorite text editor, enter the stuff, save and exit. From a shell make it executable using chmod, example

Code:

chmod 744 testscript

Then run the script and see what happens.

Might help if you posted the script in code box for us to review.

I've already tested script and there's nothing wrong with it.

Ok then, lets have a look at the rc.local with your script included.

Code:

#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
#

touch /var/lock/subsys/local

. /etc/rc.d/rc.firewall

Not sure why it would "crash" your system, but you don't need the (dot space) at the front of the line when you're running it from rc.local.

Cheers.
