 /* 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
