Login as the root user to SSH and run the following commands to install CSF:

# <span class="crayon-e">wget </span><span class="crayon-v">https</span><span class="crayon-o">:</span><span class="crayon-c">//download.configserver.com/csf.tgz</span>
# tar -xzf csf.tgz
# cd csf
# sh install.sh


If you would like to disable APF+BFD (which you will need to do to avoid conflicts):

# sh disable_apf_bfd.sh


Now, you can then configure csf and lfd in WHM, or edit the files directly in /etc/csf/*
To Configure the CSF Firewall
