The hardware layout I’ll be using is fairly simple. The Rpi 3 has built in interfaces for both wired and wireless connections. I’ll be using the wired connection as my packet sniffing port. It will not have any IP bound to it….

Do keep in mind that any plugins or templates that are not standard are not included in this backup.  This simply gives…
