+ | |||
+ | When running in the default mode (no ESSIDs) or with the -P parameter, the -C option can be used to enable beacon broadcasting of the ESSIDs seen by the directed probes. This allows one client which is probing for a network to result in a beacon for the same network for a brief period of time (the -C parameter, which is the number of seconds to broadcast new probe requests). This works well when some clients are sending directed probes, while others listen passively for beacons. A client which does directed probes results in a beacon which wakes up the passive client and causes the passive client to join the network as well. This is especially useful with Vista clients (which listens passively for beacons in many cases) which share the same WiFi? network as Linux/Mac OS X clients which send directed probes. | ||
