Firewall
 
Well I have apache and mysql set up and just thought about a fire wall, back in the day i used to use firestarter, I think that was about slackware 9. I am not very good at iptables though I do understand it is the way to go. If anyone knows an easy way to set up iptables (for dummies) or know of a good firewall for slackware 13.1, I would appreciate the help. I am sure after many hours of reading I could probably start to build some Iptables but I am just not secure enough in my abilites, currently.
I have done some research on the forums, but I want to make sure the information I am getting is up to date.

Thank you in advance to all helpful replies.

P.S. I really like the slackware community. It is one of the reasons I use it. Everyone here has no problems lending a hand to help out, those who have done their research.

Give Alien Bob's firewall generator a try. ( a lot of good stuff on Eric's site! :) )

Try using Alien Bob's firewall generator for slackware

GazL Beat me to it, lol ;)

GazL 04-28-2011 02:39 PM
lol. close one there. Could have gone either way daedra. ;)

Well I noticed that firewall generator, and just wanted to be sure, so of course I took the unanimous advice ;) set up using the script copied the generated script, chmod +x firewall after naming my script firewall, then ran firewall. whoa errors comming out the yin yan.
perhaps it was my chmod ???

You tried to start the firewall script as a non-root user?

Shao Lung 04-28-2011 02:58 PM
Alright I redid the firewall script from the given site, renamed it, ran it as su,,, no errors,,, so fixed thanks everyone.
Lesson learned run firewall as su. lol ;)

GazL 04-28-2011 03:05 PM
If you put the script in /etc/rc.d/rc.firewall then it'll be run on every boot automatically for you.

hot dang I was gonna build a script to run it. but that is even better. Much appreciated.

mRgOBLIN 04-28-2011 07:25 PM
You'll also need to make it executable... just sayin ;)

or reboot the machine ??

mRgOBLIN 04-29-2011 07:44 PM
I should explain a little better I think.

For the /etc/rc.d/rc.firewall script to be run at boot time it needs to be set executable or it will not be started.

Code:
chmod +x /etc/rc.d/rc.firewall
You can use that script to start it manually too (without the need to reboot) but a reboot is a good test to be sure it's working as expected.

Code:
iptables -vnL
will confirm that.
