Open Source Wireless Hacking

AirFart is a wireless tool created to detect wireless devices, calculate their signal strengths, and present them to the user in an easy-to-understand fashion. It is written in C/C++ with a GTK front end. Airfart supports all wireless network cards supported by the linux-wlan-ng Prism2 driver that provide hardware signal strength information in the "raw signal" format (ssi_type 3). Airfart implements a modular n-tier architecture with the data collection at the bottom tier and a graphical user interface at the top.

WifiScanner is a tool that has been designed to discover wireless node (i.e access point and wireless clients). It is distributed under the GPL License.
