CSF (Config Server Firewall) Installation

Installation is quite straightforward:

rm -fv csf.tgz
wget http://www.configserver.com/free/csf.tgz
tar -xzf csf.tgz
cd csf
sh install.sh

You should not run any other iptables firewall configuration script. For
example, if you previously used APF+BFD you can remove the combination (which
you will need to do if you have them installed otherwise they will conflict

sh /etc/csf/remove_apf_bfd.sh

That's it. You can then configure csf and lfd in WHM, or edit the files
directly in /etc/csf/*

csf is preconfigured to work on a cPanel server with all the standard cPanel
ports open. It also auto-configures your SSH port if it's non-standard on

You should ensure that kernel logging daemon (klogd) is enabled. Typically, VPS
servers have this disabled and you should check /etc/init.d/syslog and make
sure that any klogd lines are not commented out. If you change the file,
remember to restart syslog.

See the readme.txt file for more information.

Removing csf and lfd is even more simple:

cd /etc/csf
sh uninstall.sh
