• Possibility to choose the frequency (2.4 or 5GHz)
• Traffic filter by packets and/or host
• Capture all stations connected to specified AP
• Deauthentication of all stations or selected stations
• Capture station handshake
• Sniff traffic with tcpdump and save it in a pcap file

Dependencies :

• aircrack-ng
• dot11decrypt
• tcpdump

Examples :

   wpasnff -t BSSID+PSK -p http,pop3 -c -F

   wpasnff -t BSSID+PSK -p get,post  -v t192.168.1.1

   Use -h options to get more information

Before start the script you should capture information about BSSID and frequency(2.4 or 5) of the target AP. Airodump with --band option will help you.
