Kismet is an 802.11 layer-2 wireless network detector, sniffer, and intrusion detection system. It will work with any wireless card that supports raw monitoring (rfmon) mode, and can sniff 802.11a/b/g/n traffic. It can use other programs to play audio alarms for network events, read out network summaries, or provide GPS coordinates. This is the main package containing the core, client, and server.
Meant to be run inside the Kismet IPC framework.
Start the Kismet server, using the wireless interface as the capture source (-c wlan0) and use the external GPSD option (–use-gpsd-gps):
