Sometimes we may require to remove APF from the server. Here is a guide which shows how to remove APF completely from the server.

Stop the firewall first
service apf stop
/bin/rm -rfv /etc/apf
Remove the cron for APF
/bin/rm -fv /etc/cron.daily/fw
/bin/rm -fv /etc/init.d/apf
lastly disable at startup
chkconfig apf off

This should remove APF completely from the server as we removed the APF daemon, cron and files.

While installing APF on your VPS you get the following error :

# apf -r
apf(28442): {glob} status log not found, created
apf(28463): {glob} flushing & zeroing chain policies
apf(28463): {glob} firewall offline
apf(28500): {glob} activating firewall
apf(28551): {glob} unable to load iptables module (ip_tables), aborting.
apf(28500): {glob} firewall initalized
apf(28500): {glob} !!DEVELOPMENT MODE ENABLED!! – firewall will flush every 5 minutes.

You need to configure the APF for your VPS.

nano -w /etc/apf/conf.apf

modify
SET_MONOKERN=”0″

to
SET_MONOKERN=”1″

Restart APF

apf -r
