\fBarpspoof\fR [\fB-i \fIinterface\fR] [\fB-t \fItarget\fR] \fIhost\fR
.SH DESCRIPTION
.ad
.fi
\fBarpspoof\fR 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.
.LP
Kernel IP forwarding (or a userland program which accomplishes the
same, e.g. fragrouter(8)) must be turned on ahead of time.
.SH OPTIONS
.IP "\fB-i \fIinterface\fR"
Specify the interface to use.
.IP "\fB-t \fItarget\fR"
Specify a particular host to ARP poison (if not specified, all hosts
on the LAN).
.IP \fIhost\fR
Specify the host you wish to intercept packets for (usually the local
gateway).
