>Description:
Duplicate packets appear when either machine belonging to one session are in promiscous mode
and using wi0 (Orinoco Gold 802.11b wireless cards in my case), this behaviour has also been
observed on OpenBSD and NetBSD
>How-To-Repeat:
Just put either side of the wireless link or cards connected to an AP in promiscous mode
and ping the other machine that is also using a wireless card. the more machines are in promiscoui s mode the more DUP you get.
