Ubuntu Kismet - An 802.11 wireless network detector, sniffer, and intrusion detection system

Kismet is a 802.11b wireless network sniffer. It is capable of sniffing using almost any supported wireless card using the Airo, HostAP, Wlan-NG, and Orinoco (with a kernel patch) drivers.
Can make use of sox and festival to play audio alarms for network events and speak out network summary on discovery. Optionally works with gpsd to map scanning.

Kismet identifies networks by passively collecting packets and detecting standard named networks, detecting (and given time, decloaking) hidden networks, and infering the presence of nonbeaconing networks via data traffic.


Install Kismet in Jaunty

sudo apt-get install kismet

Configuring Kismet

First you need to configure kismet.conf file from your terminal use the following command to open

sudo gedit /etc/kismet/kismet.conf

Change the following options
Uncomment the line #suiduser=your_user_here and add your username that you use to login to Ubuntu.

suiduser=ruchi

Next you want to change is the “source=none,none,addme” line. This is where you will add your supported wireless card information.

Some Examples

If you are running Alfa wifi change

source=none,none,addme

to

source=rt8180,mon0,alfa

If you are running Atheros AR5001X+ card change

source=none,none,addme

to

source=madwifi_ag,wifi0,madwifi

If you are running Intel 2100 driver

source=none,none,addme

to

source=ipw2200,eth1,wifi

Useful Notes

If you don’t know your relevant network driver, view the Kismet Readme and scroll down to the section “12. Capture Sources”.
If you don’t know your interface name, use iwconfig to find your wireless interface.
Save and Exit the file
Before starting kismet, you need to put your wireless adapter into monitor mode.

Some Examples
Run alfa wifi card in monitor mode

sudo airmon-ng check kill alfa & sudo airmon-ng start alfa

Run Atheros AR5001X+ card in monitor mode

sudo wlanconfig ath0 destroy
sudo wlanconfig ath0 create wlandev wifi0 wlanmode monitor

Finally start Kismet from the terminal using the following command

sudo kismet
