arpspoof - intercept packets on a switched LAN
arpspoof [-i interface] [-t target]
host
arpspoof redirects packets from a target host (or all hosts) on the LAN
intended for another host on the LAN by forging ARP replies. This is an
extremely effective way of sniffing traffic on a switch.
Kernel IP forwarding (or a userland program which accomplishes the
same, e.g. fragrouter(8)) must be turned on ahead of time.
- -i interface
- Specify the interface to use.
- -t target
- Specify a particular host to ARP poison (if not specified, all hosts on
the LAN).
- host
- Specify the host you wish to intercept packets for (usually the local
gateway).
