I am interested in being able log packets going over a unsecured wireless network. Specifically, I want to see HTTP POST / GET requests and responses going between the router and computers on the network. Which software do people use for this? I am running OSX and I have a RT73 chipset USB wireless card that supports passive mode.

Is there a way to do this over WEP encrypted networks (provided I know the key) as well?

I would recommended Wireshark which will track any traffic on a particular network card.

From a Wireless router perspective I am not aware of any software that can do this unless the router itself is linux based in which case you can use tcpdump

If you know the WEP or WPA password for the wireless network, you can see (and sniff) all the traffic on it. WEP/WPA only prevent users who don't know the password from seeing the traffic; once you know the password it's all open to you. – Barry Brown Aug 22 '09 at 19:37
thank you, i have used wireshark in the past, but i had no idea it was this powerful. worked perfect : ) – unknown Aug 23 '09 at 3:05

A program like AirMagnet will allow you to sniff directly from your wireless adapter, even if you aren't connected to the networks.

A program like WireShark will allow you to sniff any network you are connected to.
