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 dont know how to burn an ISO image, go to Google). This version of Linux doesnt 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 dont be overwhelmed. (Also I cant show you how to use kismet if you dont 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.

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.

Today cycle computers can do much more than just track the speed, distance and amount of time each ride takes. However there are certain other features than many of these devices now have included within them and we are going to be taking a look at just what some of these are.

heart monitor
This is ideal if you are someone who likes to know exactly what rate their heart is working at whilst they are out riding. No longer do you have to carry the additional weight of a heart rate monitor on your body instead you can let the computer do it for you. Those computers which come with a built in heart rate monitoring system then allows for additional space on your handlebars, and yet still provides the user with this essential information.

gear information
If you want to know exactly what gear you are in when out for a ride then choose one which comes with this feature as it will display through out the ride what gear you are in on the screen in front of you.

Cadence
This feature enables the rider to see at what speed they are pedalling and by being able to see this a rider is then able to choose the right gear which will then prevent them from placing to much pressure on their muscles and joints. The easier a person finds it to pedal then the much longer they will be able to ride for. one cycle computer which features this is the Vetta V100 wireless cadence kit.

Split Screen
If you are someone who wants to spend less time whilst out riding having to press buttons in order to see certain statistics or features on your device then why not choose one which comes with a split screen. These particular models then allow you to see not just the speed at which you are traveling but also your cadence as well. There are even some models which include the option for being able to display 4 functions on the screen on your handlebars.

Altimeter
If you are someone who happens to live in an area which is full of various altitudes then purchase a cycle computer which includes this particular feature within the device. This will then allow you to track the altitude at which you are currently traveling and also help to show where you have gained or loss altitude throughout the ride.

Certainly if you are looking for a cycle computer which contains the above features along with such other ones as wireless, thermometer, freeze frame memory and dual bike memory then it may be worth investing in the Vetta V100 wireless cadence kit.
