I am wanting to set up a single logging point on my home network that logs URLs and search terms to monitor teenagers... um... activity.
I was thinking of setting up a computer between the cable modem and the router, which would capture all network traffic. The upside would be no need for arp spoofing, the downside would be you would lose specific device information for if the traffic was on a wireless tablet vs wired PC.
I have played with Kali a little, and while there are some cool things like driftnet, urlsnarf, and arpspoof, they all seem to be to target a single device, and seems most tutorials are for creating wireless hotspots.
With thousands of tools available, I am not sure where to start on this, where I am wanting basically a consolidated browser history from all devices on the network.
I have a PC with a 4 port GB network card and an SSD available with Kali installed. Is my plan of putting it between the router and modem good, or should I stick with arp spoofing past the router? The router is a Linksys 1200AC.
