Capture Wireless Traffic

Using Tcpdump

tcpdump -i <interface> -s 0 -nne 'wlan type <type> subtype <subtype>'Note older versions of tcpdump and wireshark capture filter dosn't support the "wlan" keyword, just use "type <type> subtype <subtype>"

Sniffing wireless in monitor mode, ignore beacon's
tcpdump -i <interface> -s 0 -nne '(type mgt or type ctl or type data) and (not type mgt subtype beacon)'
