If you want 802.11 header monitor interface is the only way (at least to my knowledge), you can use 2 VIF's one for connection and one for monitoring. Most chipsets support this. > > 2.

You can use pcap API's, but you still need the monitor interface (use 2VIF's as above) http://wireless.kernel.org/en/users/Documentation/packetspammer -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
