Edit CSF's main config file located at /etc/csf/csf.conf and disable
FASTSTART by editing FASTSTART = “1” to FASTSTART = “0”. Once the change
is made restart CSF's rules by running the following command:
csf -r
After this, check both services and if any of them has not started
automatically you can now restart them manually by using the systemctl
command like this:
systemctl start csf.service
systemctl start lfd.service
