Wellenreiter is a wireless network discovery and auditing tool. Prism2, Lucent, and Cisco based cards are supported. It is the easiest to use Linux scanning tool. No card configuration has to be done anymore. The whole look and feel is pretty self-explaining. It can discover networks (BSS/IBSS), and detects ESSID broadcasting or non-broadcasting networks and their WEP capabilities and the manufacturer automatically. DHCP and ARP traffic are decoded and displayed to give you further information about the networks. An ethereal/tcpdump-compatible dumpfile and an Application savefile will be automaticly created. Using a supported GPS device and the gpsd you can track the location of the discovered networks.
