DNSSPOOF(8)

NAME
dnsspoof - forge replies to DNS address / pointer queries

SYNOPSIS
dnsspoof [-i interface] [-f hostsfile] [expression]

DESCRIPTION
dnsspoof 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.

OPTIONS

-i interface
    Specify the interface to use.

-f hostsfile
    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 *.doubleclick.net).

expression
    Specify a tcpdump(8) filter expression to select traffic to sniff.

If no hostsfile is specified, replies will be forged for all address queries on the LAN with an answer of the local machine's IP address.

FILES

/usr/local/lib/dnsspoof.hosts
    Sample hosts file.

SEE ALSO
dsniff(8), hosts(5)
