"Put the interface in monitor mode. No packets are transmitted, and received packets are discarded after bpf(4) processing." Now, using ifconfig ath0 monitor up does not seem to be doing that. By using ifconfig ath0 debug monitor up I get the following (presented in abbreviated form) -------------------------------- ath0: begin active scan ath0: sending probe_req to ff:ff:ff:ff:ff:ff on channel xx (this repeats for all channels) during this you get an occasional ath0: received probe_resp from xx:xx:xx:xx:xx:xx rssi xx and ath0: received beacon from xx:xx:xx:xx:xx:xx rssi xx ath0: macaddr bssid chan rssi rate flag wep essid - yy:yy:yy:yy:yy:yy yy:yy:yy:yy:yy:yy y y y y y y + xx:xx:xx:xx:xx:xx xx:xx:xx:xx:xx:xx x x x x x x ath0: sending auth to xx:xx:xx:xx:xx:xx on channel xx ath0: receiving auth from xx:xx:xx:xx:xx:xx rssi xx ath0: sending assoc_req to xx:xx:xx:xx:xx:xx on channel x ath0: received assoc_resp from xx:xx:xx:xx:xx:xx on channel x ath0: associated with xx:xx:xx:xx:xx:xx ssid "x" channel x start xx --------------------------------- Why does it do this, in "monitor mode". Knowing the above man page description. Once it associates, it stays there. No scanning is done. Am I missing something?
