Sure will, but it's called a packet filter, not a sniffer. I think a
generally accepted characteristic of a sniffer is that it captures
packets not intended for it off the wire, as opposed to packets flowing
through it, a' la packet filtering routers.
And at least the Novell LANalyzer product goes beyond passivity: it will
do load generation by spewing packets and will also replay captured packet
streams back onto the wire. Or at least, my version does, but since it
doesn't exist, according to Novell, I may be a figment of my own
imagination....
