Wardriving a act for searching and locating the access points (APs), as discussed on the wardriving article about the importance of wireless sniffer. These tools use to find out the wireless network, just like netstumbler for windows and Kismac for MAC, there is a Kismet for Linux. Purpose is same to sniff the wireless LAN and try to get maximum information about that network.

Kismet is a wireless network detector and sniffer and it works with any wireless card (NIC card) which supports raw monitoring mode.
Kismet identifies networks by passively collecting packets and detecting networks, which allows it to detect (and given time, expose the names of) hidden networks and the presence of non-beaconing networks via data traffic.

The single need to run Kismet is Linux OS, this may be a Ubuntu, backtrack or any other, however it can be applicable on windows but this time we consider only Linux, you can get Kismet from here and the second way is via terminal, open terminal and type,

sudo apt-get install kismet

Kismet Tutorial

After installation you need to configure Kismet now open terminal and type exactly.

sudo gedit /etc/kismet/kismet.conf

Now create the username for login to Kismet window,

suiduser=your_username_here

Now at this stage you have to tell the kismet about the source of wireless adapter to use. The command is

source=type,interface,name

and in my case

source=prism,wlan0,hostap

If you don’t know your relevant network driver, view the Kismet Readme and scroll down to the section “12. Capture Sources”. Now start Kismet by the following command.

sudo kismet
