/* Its just a simple rfmon mode sniffer
i hope my C is at last a bit better then in my
early days :-).
This works only with cisco wireless cards with an rfmon
able driver and not with wifi stuff.
Btw. did i mention that i hate C?
To compile use:
- gcc wlan-sniffer.c -o wlan-sniffer -lpcap
-
- use it like this:
- wlan-sniffer interface
+ gcc sniffer.c -o wlan-sniffer -lpcap
