Is there a way to sniff packets encrypted with WPA(2)?

Question

I was reading about the recent FireSheep tool. People are saying that it is fine to sniff WPA/2 PSK networks because if you have the PSK, you can decrypt anyone's traffic.

I am wondering if there are any sniffers that actually decrypt and sniff in real time, that would actually allow that sort of attack?

Answer 1

Sure, probably the best known being Wireshark. It's free too!
