Re: Wireless SSID discovery

Hi Andrew,

I know you have got some answers that point you in the right direction, 
but for the record, some APs use the 'hide SSID' function to remove the 
SSID from the beacon frames, but they still include it in the probe 
replies (i.e. Netstumbler will still catch it). A passive scanner such 
as Kismet would have to wait until a client probed or associated or 
reassociated to the AP. Other APs will also remove the SSID from the 
probe responses, or not respond to probes at all (the early Intel APs 
did this by default, their out-of-the-box SSID was 101).

Hiding the SSID is false security, any person one step higher than a 
kiddie will be able to get it from sniffing one way or another. It can 
also affect the network's performance.

Best regards,
