Kismet is a wireless network detector / sniffer which can give you a vast amount of information about wireless networks. Wireless network security flaws are well documented but often very hard for the common person to understand. I will be showing you how to use kismet with out even having to install Linux, or compile kismet.
First you need to proceed to remote-exploit.org and download and burn their Auditor CD. (IF you don’t know how to burn an ISO image, go to Google). This version of Linux doesn’t install or modify your hard drive; it will boot from the CD and use a Ram Drive (On your Memory).
Auditor is not only a great tool for testing wireless network security with kismet but it also has many other computer security tools on it as well.
Client Window
Next, to start Kismet proceed to the Linux version of the start menu, and press Auditor.
Now proceed to the wireless /scanning/kismet tools/kismet.
Once you click on Kismet it will ask you for a default location to place the Kismet log files for analyzing later, just press the desktop or temp file.
Now I will show you how to use Kismet. When kismet initially opens you will see a greenish box with numbers and network names (If any are near you) clicking away don’t be overwhelmed. (Also I can’t show you how to use kismet if you don’t have the correct wireless adapter, get an ORINICO Gold Classic Card off EBAY.) The Orninco gold classic card will be automaticly detected by auditor linux.
The Kismet columns will show the wireless networks SSID (Name), Type of device (Access point, gateway) Encryption or no Encryption, an IP range and number of packets. Kismet will pick up hidden networks with SSID broadcast Disabled also, Netstumbler will not.
Now Press H, to bring up the Help Menu. This will give the nuts and bolts on how to use kismet. If you tab down to the network you are auditing and press “C”, Kismet will show you all the computers that are using that wireless access point / gateway. This Kismet screen will show you the clients MAC address, Manufacture of Wireless Adapter, IP address range and traffic.
Kismet: Help Menue
Now to get out of that screen press “Q”. Tab Down on the Main Kismet Screen to another SSID and press “I”. This Kismet window will show detailed information about the wireless network. The Kismet detail screen will show the type of network (Infrastructrure / Adhoc), signal strength, channel, encryption type, and much more.
Kismet will also give you sound alerts when new wireless networks are discovered or security alerts or suspicious clients are in range. Suspicious clients would be people like you who are using Kismet or Networkstumbler. Unlike you these could be Wardrivers looking for venerable networks to hack into.
Kismet Alert Page
You can prevent War drivers from discovering your wireless network by performing a proper site survey which will help limit signal bleed off to unneeded areas. You should write down the suspicious MAC address and keep an eye on your access logs. If the War Drivers are really stupid just look out your window and look for cars with weird antennas.HA HA HA.
Kismet is more than just a tool to discover wireless networks; it can be used in conjunction with other tools to crack WEP/WPA. Many websites will claim that WEP can be cracked in less that five minutes. This is only half the truth because it could take many hours,days,months to gather enough packets to crack. Good luck and have fun learning the more advanced applications of kismet.

Wireless Network Security: How to Use Kismet
December 13th, 2009Setting up a Network — Wired or Wireless?
November 19th, 2009
To Wire or Not to Wire
Wireless networks are en vogue, but your installation won’t be successful unless you chose the right type of network and set it up properly. Wired networks require that each computer be connected via a wire to a central location, called a switch or hub. This often involves installing cables through walls and ceilings and can present a challenge for anyone.
If the computers in your home or office are all within 500 feet of each other, a wireless network might be for you. A wireless network has no cables. It can connect computers on different floors of a building or even across the street. Aside from the obvious benefit of not having wires, wireless networks are more convenient since the setup, configuration, and reconfiguration can often be done within minutes, without extensive planning.
Wireless networks, however, are not as fast as wired networks. If you play computer games or want to view streaming video or other high-speed multimedia, a wireless network might not have enough capacity. But, if you just want to check e-mail and view web pages, a wireless network is a good choice. To install a wireless network, you need a Wireless Access Point and a wireless network card for each computer. You will need to buy a wireless network card for each desktop computer, although most newer laptops come equipped with one.
Security is not a large concern in a wired network, since someone would have to physically connect to a wired network to break in. In wireless networks, a car parked outside with a laptop could easily connect to your network if you don’t have proper security in place. To prevent this from happening, encrypt your wireless network connections, or set a password to access the network, or do both.
Do It Yourself or Call a Professional?If you decide to use a wired network, consider whether you will install it yourself or hire a professional. If you have a small number of computers that are all situated very close to one another, you may be able to buy pre-assembled network cables and connect them yourself. If you need to wire multiple floors and lay wire through ceilings and walls, you need a professional installation. If you go this route, it is best to begin with a floor plan of your office or home, determine what your current needs are, and consider how the network design can be adapted to future needs. A professional installer should be familiar with EIA/TIA standards, local wiring and electrical codes, and making custom cables. Network cabling professionals are often judged by the neatness of their work, because sloppy cabling is more apt to deteriorate over time, harder to manage, and poses more of a fire risk.
Having a wireless network or a wired network is not mutually exclusive. Many small offices have a wired network in addition to one or more wireless networks, depending on their needs. Wireless networks are continuing to get faster, more secure, and less expensive. Wired networks will continue to coexist with wireless networks, often in the same homes and offices.
