WaveStumbler is console based 802.11 network mapper for Linux. It reports the basic AP stuff like channel, WEP, ESSID, MAC etc. It has support for Hermes based cards (Compaq, Lucent/Agere). It still in development but tends to be stable.

It consist of a patch against the kernel driver, orinoco.c which makes it possible to send the scan command to the driver via the /proc/hermes/ethX/cmds file. The answer is then sent back via a netlink socket. WaveStumbler listens to this socket and displays the output data on the console.
