APF installation

cd /usr/local/src/
wget http://www.rfxnetworks.com/downloads/apf-current.tar.gz
tar -zxvf apf-current.tar.gz; cd apf-*

You will get the following error when you try to restart/start apf every time.

apf(660): {glob} !!DEVELOPMENT MODE ENABLED!! – firewall will flush every 5 minutes.

This is because of the development mode enabled in APF configuration file. You can disable it by editing the configuration file.
Details from APF configuration file regarding development mode:

# !!! Do not leave set to (1) !!!
# When set to enabled; 5 minute cronjob is set to stop the firewall. Set
# this off (0) when firewall is determined to be operating as desired.
DEVEL_MODE=”1″

Edit the configuration file and set DEVEL_MODE=”0″, then restart APF using the command “apf -r“.
