ConfigServer software
Many of our Technical Support Analysts recommend that you use ConfigServer Security & Firewall (CSF), a free product that ConfigServer provides. CSF contains a stateful packet inspection (SPI) firewall, a login and intrusion detection mechanism, and a general security application for Linux servers.
CSF does not function with the firewalld utility. If you install CSF, you must remove the firewalld utility. To do this, run the yum remove firewalld command.
To install CSF, perform the following steps:
-
Log in to your server as the
rootuser via SSH. -
Run the
cd /rootcommand to change to the root directory. -
Run the following command to download CSF:
wget https://download.configserver.com/csf.tgz -
Run the
tar -xzf csf.tgzcommand to decompress the downloaded file. -
Run the
cd csfcommand to change directories. -
To begin the CSF installation, run the
./install.cpanel.shcommand.
To configure CSF, use WHM’s ConfigServer Security & Firewall interface (WHM » Home » Plugins » ConfigServer Security & Firewall). The installation script should enable the correct ports in CSF, but we recommend that you confirm this on your server.
After you configure CSF, you must disable testing mode. To take CSF out of testing mode, perform the following steps:
-
Click Firewall.
-
Change the value of Testing from
1to0. -
Click Change.
- In cPanel servers: Code: cd /etc/csf
- sh uninstall.sh.
CSF does not function with the firewalld utility. If you install CSF, you must remove the firewalld utility. To do this, run the yum remove firewalld command.
