ARPSPOOF(8)                                           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  accom-
       plishes  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)
