SwitchSniffer is a program that can scan your switched LAN for up hosts and can reroute and collect all packets without the target users' recognition. It can also detect the ¡®arpspoofer¡¯ program running on the network and block user definable sessions like firewall. If you use this program in tandem with any sniffer program, you can capture and see the users IDs and passwords on a switched network.
