Not really too practical though, since you'd have to see the client from all 3 transcievers. You'd also have to map out the distance/signal strength in order to accurately superimpose a map (also consider differences in obstructions.) And, different radios have different power... Plus, wifi's range is not all THAT fantastic... so even if you have the client on all three transcievers, the area they could be in is fairly limited, especially if we're only talking about one floor. If you're concerned about security... what the hell am I talking about... you're running OpenBSD, no, wait, it's a FANTASTIC OS even without the security stuff which is really just a product of excelence... Lock that network down and use authpf =). Some sort of authenticated gateway... wonder if anything else can do that besides pf. Meh. Travers Buda
