Kismet is an 802.11 layer2 wireless network detector, sniffer, and intrusion detection system. Kismet will work with any wireless card which supports raw monitoring (rfmon) mode, and can sniff 802.11b, 802.11a, and 802.11g traffic.

Kismet identifies networks by passively collecting packets and detecting standard named networks, detecting (and given time, decloaking) hidden networks, and inferring the presence of nonbeaconing networks via data traffic.
kismet supports logging to the wtapfile packet format (readable by tcpdump and ethereal) and saves detected network informat as plaintext, CSV, and XML. kismet is capable of using any GPS supported by gpsd and logs and plots network data.

kismet is divided into three basic programs, kismet_server kismet_client and gpsmap


kismet handles automatically starting kismet_server and kismet_client.
kismet is installed as suid-root by default. It will drop privs to the user specified in kismet.conf immediately after binding and configuring the capture source.


kismet_server captures, dissects, and logs packets and GPS data. It is capable of running in `headless' mode with no display. Multiple clients (on multiple computers) can be connected to a single server.

Set the initial channel for a channel source (source:channel)
Forcibly enable the channel hopper
Forcibly disable the channel hopper
Set the title used for the %t field of the logfile template (Default: Kismet)
Disable all logging
Use an alternate config file
Override capture source lines (type,interface,name). Refer to kismet.conf(5) for more information. Multiple capture source options can be specified for multiple sources. All sources provided here are automatically enabled unless an enable list is also supplied.
Comma-separated list to override what capture sources are enabled.
Override logging types, comma separated (dump, cisco, weak, csv, xml, gps)
Override maximum packets logged per file
Override sound option and run in quiet mode
Override GPS host:port
Override port to listen on for clients
Override list of client IPs or network/mask blocks (comma separated) allowed to connect
Run in silent mode (no console status information)
Override server name for this instance of Kismet

kismet_client is a ncurses and panels interface which connects to the server and displays detected networks, statistics, network details, etc.

Use an alternate config file
Use an alternate UI config file
Override sound option and run in quiet mode
Override server host:port
Attempt to automatically restablish the connection if the server terminates
Override UI type (curses, panel)
Override list of columns to display (comma seperated)

gpsmap reads GPS and Network XML datafiles and plots networks on downloaded maps or user-supplied images (such as satellite photos).
