Simple sniffing and cracking(Scanning Wireless networks )

The first thing to do is looking out for a potential target. The aircrack-ng suite contains airodump-ng for this - but other programs like Kismet can be used too. Prior to looking for networks, you must put your wireless card into what is called “monitor mode”. Monitor mode is a special mode that allows your computer to listen to every wireless packet. This monitor mode also allows you to optionally inject packets into a network. Injection will be covered later in this tutorial.
