Building a war-drive kit
Footprinting : locating APs
- passive: listening to AP broadcasts
- active: transmitting client beacons in search of AP responses
- cards (802.11.b, 11.g) -- choose the software first
- Antennas (e.g. HyperLink Tech)
- NetStumbler (set SSID to ANY) active mode. Counter-measure: set AP not to reply to probes.
