Come on, folks, this discussion has gone beyond noise into the realms of absurdium. TDR's only work with coax. 10BaseT greatly complicates things. Furthermore a TDR only can find unauthorized taps. The original question did not say "how can I find unauthorized taps on my wire". It was "how can I detect a sniffer". These are two very different questions. So can we all please shut up about this topic and get back to the subject of the list? --Dave
