Debian iptables

kingcomein · 10-26-2005, 02:15 AM

When i type "iptables -L" under command line that login as root.
It displayed below messages:

Note: /etc/modules.conf is more recent than /lib/modules/2.2.20-idepci/modules.dep
modprobe: Can't locate module ip_tables iptables v1.2.11: can't initialize iptables table 'filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

What should I do?

thx....

Hi,

What do you want to do ?
Install a firewall ?
Then install guarddog, sets iptables for you with
a gui.

# apt-get install guarddog

cheers

I want to set up the iptables.

I solve the above problem by updated the kernel.

But i have any other problem, how to save the change after i set the iptables rules?

I used the command:

"iptables-save -c" <---- but cannot work after i reboot the debian once.

"/etc/init.d/iptables save active" <----- it displayed "Bad argument 'save'"

have anyone know how can i do ?

I used

Code:

iptables-save > /etc/my-iptable-rules

and the load on boot with

Code:

iptables-restore < /etc/my-iptable-rules

You need create a bash script with an editor and then save the script as say rc.firewall in either /etc or /etc/init.d/.
Having saved the script cd to the directory and do chmod 700 ./rc.firewall . To get it running at boot time and say you saved it in /etc/init.d then do from a console;

ln -s /etc/init.d/rc.firewall /etc/rc2.d/S89rc.firewall. Now you need to do this in the runlevels rc3.d -> rc5.d so use the up arrow key so the line appears again and use the back arrow key and just change the runlevel from 2 to 3.

TigerOC - just a comment a good explanation for loading up the firewall at boot, but shouldn't the firewall be initiated a little earlier, before any network services such as Apache, MySQL, etc. would be started?
