One question that I've been meaning to ask and this seems to be close to
being on-topic:  If you're running a sniffer in promiscuous mode on a 
network that is linked together via a switch (as opposed to a hub), will
you still be able to passively capture all packets from all boxes on the
net?  Or is that one of the purposes of the switch - to ensure privacy?
Is there any way around this?
