.TH DNSSPOOF 8
.ad
.fi
.SH NAME
dnsspoof
\-
forge replies to DNS address / pointer queries
.SH SYNOPSIS
.na
.nf
.fi
\fBdnsspoof\fR [\fB-i \fIinterface\fR] [\fB-f \fIhostsfile\fR] 
[\fIexpression\fR]
.SH DESCRIPTION
.ad
.fi
\fBdnsspoof\fR forges replies to arbitrary DNS address / pointer queries
on the LAN. This is useful in bypassing hostname-based access controls,
or in implementing a variety of man-in-the-middle attacks.
.SH OPTIONS
.IP "\fB-i \fIinterface\fR"
Specify the interface to use.
.IP "\fB-f \fIhostsfile\fR"
Specify the pathname of a file in hosts(5) format. Only one hostname
allowed per line (no aliases), although hostnames may contain
wildcards (such as \fI*.doubleclick.net\fR).
.IP "\fIexpression\fR"
Specify a tcpdump(8) filter expression to select traffic to sniff.
.LP
If no \fIhostsfile\fR is specified, replies will be forged for all
address queries on the LAN with an answer of the local machine's IP
address.
.SH FILES
.IP \fI/usr/share/dsniff/dnsspoof.hosts\fR
Sample hosts file.
.SH "SEE ALSO"
