ARPSPOOF(8)							   ARPSPOOF(8)

NAME
       arpspoof - intercept packets on a switched LAN

SYNOPSIS
       arpspoof [-i interface] [-c own|host|both] [-t target] [-r] 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.

       -c own|host|both
	      Specify which hardware address t use when restoring the arp con‐
	      figuration;  while cleaning up, packets can be send with the own
	      address as well as with the address of the host. Sending packets
	      with  a  fake  hw	 address can disrupt connectivity with certain
	      switch/ap/bridge configurations, however it works more  reliably
	      than  using  the	own address, which is the default way arpspoof
	      cleans up afterwards.

       -t target
	      Specify a particular host to ARP poison (if not  specified,  all
	      hosts on the LAN). Repeat to specify multiple hosts.

       -r     Poison  both  hosts (host and target) to capture traffic in both
	      directions.  (only valid in conjuntion with -t)

       host   Specify the host you wish to intercept packets for (usually  the
	      local gateway).
