Howdy,

I seem unable to be able to detect network traffic in promiscuous mode. In searching for the traffic to and from another computer, all I get, no matter what I do on the other computer is something like the following:



sudo tcpdump -nnvvtei wlan0 | grep -i 192.168.1.112
tcpdump: listening on wlan0, link-type EN10MB (Ethernet), capture size 65535 bytes

Ad nauseum. I don't know what other details you need, or what might be wrong, but I'd appreciate any help I can get.
