ARPSPOOF(8)

NAME

arpspoof - intercept packets on a switched LAN

SYNOPSIS

arpspoof [-i interface] [-t target] host

DESCRIPTION

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.

OPTIONS

-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).

SEE ALSO

dsniff(8), fragrouter(8)
