How to start IPTABLES script automatically on boot.

[Gunman1982]

I am sorry, it was a typo error, i have S24HAL and S24dhcdbd?
Yet, it didn't work, my script did execute?

Yes you can have different scripts with the same number, its just an order on boot the lowest numbers are executed first and if multiple same bumbers exists I guess they execute in alphabetical order, anyway it should execute.
Make sure your script is executable 'chmod 755 /etc/init.d/iptables' and the first line in your script is '#!/bin/bash'
You can check /var/log/messages to see if there are maybe errors regarding your script.

Is there anyway to run the scripts in the RC directories without rebooting.

You can switch between runlevels with the help of the 'init' command. To make sure switch to runlevel 1 'init 1' and then back to 3-5 'init 3', 'init 4' or 'init 5'

ok. I have changed the permissions of the file and created links as required. and the first line in the script is #!/bin/bash

Let me check the /var/log/messages and get back to you.

If if you want to add run level scripts -- with debian the proper way to do it is with the update-rc.d executable. I would recommend this way rather than creating a bunch of symbolic links and such. It takes care of adding to the appropriate run levels and supplies the links.

Here are some examples:

This is good information. I will try this today and get back to you.

Thanks

update-rc.d <name of script> defaults

this will make links as per below:

root@alice:/root# update-rc.d firewall.sh defaults
