To be honest, I dont know how you would do it on only 3 of them. Because if your computer that is doing the sniffing has anything hooked up at all to the transmit side.....collisons....broadcast from the sniffing box.....attenuation (hope that is spelled right) issues....
I do it with 2 nics and bond them together and the way they are connected to the box that is sniffing; it wont allow them to transmit. They are only connected to 2 and 6 on both nics. Which should only allow to receive. If someone else has any thoughts....throw them on here because I would like to know. As far throughput issues....have not seen any. I kept the twists as tight as possible. Keeping the loss to a minimum.
