.SH NAME
arpspoof
\-
intercept packets on a switched LAN
.SH SYNOPSIS
.na
.nf
.fi
\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).
.SH "SEE ALSO"
dsniff(8), fragrouter(8)
