Does anyone know of a good way to detect people "sniffing" on the network? IE a
program that will detect a machine running in promiscuous mode?

I was wondering the same thing when I read a clause prohibiting the use of network cards in promiscuous mode in the CMU network use policy. I asked some computer security people I knew about this and their response was that it is not possible to detect if a network card is in promiscious mode unless you have access to the machine it's in - i.e., that you can look at ifconfig on that machine.

<STUPID QUESTION>

What is the range of sniffing? I.E. can the "sniffer" sniff past switched
networks? What is the "range" of sniffing?

Thanks
