Network Associates Sniffer PRO – SnifferPro

This sniffer is aimed at generating LAN statistics, not directly to snort the contents of the traffic, but it helps us to investigate the traffic itself, which protocols are the most used, what traffic is there between which PC's and which PC's, Usage Statistics… GOOD, Like almost all sniffers, the important thing is that it controls the traffic that passes through it, that is, by your network card(s); so the ideal is to put it connected to the PC (where the Sniffer Pro is installed) to the router by a network card (with crossed cable, or whatever), and enable routing between the two network cards, si no sabes a que me refiero me puedes preguntar)
