ConfigServer Security&Firewall; update breaks LFD

September 7th 2020

An update breaks LFD meaning no file exists at /usr/sbin/lfd. This is fixed by reinstalling the ConfigServer Security&Firewall product.

This can be done in WHM -> Terminal or through SSH by running the following commands:

cd ~

wget https://download.configserver.com/csf.tgz

tar -xzf csf.tgz

cd csf

./install.cpanel.sh

service lfd start

OR one-liner:

wget https://download.configserver.com/csf.tgz && tar -xzf csf.tgz && cd csf && ./install.cpanel.sh && service lfd start
