Installing and Configuring CSF Firewall
This
article demonstrates how to install and configure the CSF
(configserver) firewall. CSF can be used on a wide range of Linux
systems, including those running cPanel.
rm -fv csf.tgz
wget http://www.configserver.com/free/csf.tgz
tar zxf csf.tgz
cd csf
sh install.sh
If you have APF + BFD you will need to disable it, you can use the following to do so:
sh disable_apf_bfd.sh
To
configure CSF modify the config files in /etc/csf/ - or if you are
running WHM you can modify the CSF settings in there. By default CSF
opens the standard cPanel ports.
