Re: Sniffing on a switch

[Mikael Kuisma <kuisma () ping se>]

Actually, you inject false ARP entries into the two end systems 
communication
through the switch, redirecting the IP packages, so the end systems 
sends them
to you instead of each other. You can then "sniff" them, and re-send them to
the intended recipient.
