Create a file called 'ApprovedNodes' or copy the template file (ApprovedNodes.template) and on each line, insert all known/valid mac addresses that belong on your network. The script will check this file as reference for known mac addresses.

Once tested manual, set it up to run at your intended interval in cron.
