@node Overview
@chapter Overview of @command{macchanger}
The GNU @code{macchanger} utility helps to view and manipulate the MAC
address of network interfaces.
@node Features
@chapter Features
@itemize @bullet
@item Set specific MAC address of a network interface
@item Set the MAC randomly
@item Set a MAC of another vendor
@item Set another MAC of the same vendor
@item Set a MAC of the same kind (eg: wireless card)
@item Reset MAC address to its original, permanent hardware value
@item Display a vendor MAC list (more than 17000 items) to choose from
@end itemize
@node Invoking macchanger
@chapter Invoking macchanger
The program accepts the following options.
@table @samp
@item -h
@cindex @code{-h}
@itemx --help
@cindex @code{--help}
Print a usage message briefly summarizing these command-line options
and the bug-reporting address, then exit.
@item -V
@cindex @code{-V}
@itemx --version
@cindex @code{--version}
Print the version number of @command{macchanger} to the standard output stream.
This version number should be included in all bug reports.
@item -s
@cindex @code{-s}
@itemx --show
@cindex @code{--show}
Print the current MAC address and exit. This is the default action when no
other option is specified.
@item -e
@cindex @code{-e}
@itemx --ending
@cindex @code{--ending}
Change the MAC address setting the same hardware vendor as the current.
@item -a
@cindex @code{-a}
@itemx --another
@cindex @code{--another}
Change the MAC address setting a random vendor MAC of the same
kind. For example, if it's a wireless card, @command{macchanger} will
set another wireless MAC address.
@item -A
@cindex @code{-A}
Change the MAC address setting a random vendor MAC of any kind.
@item -r
@cindex @code{-r}
@itemx --random
@cindex @code{--random}
Set fully random MAC address: Any kind and any vendor.
@item -p
@cindex @code{-p}
@itemx --permanent
@cindex @code{--permanent}
Reset MAC address to its original, permanent hardware value.
@item -l
@cindex @code{-l}
@itemx --list[=@var{keyword}]
@cindex @code{--list}
Print known vendors. If a key is spefified, @command{macchanger} will
print only vendor that matches the string.
@item -b
@cindex @code{-b}
@itemx --bia
@cindex @code{--bia}
When setting fully random MAC pretend to be a burned-in-address. If not used,
the MAC will have the locally-administered bit set.
@item -m
@cindex @code{-m}
@itemx --mac=@var{XX:XX:XX:XX:XX:XX}
@cindex @code{--mac}
Set a specific MAC address. Each XX must be an hexadecial value (00 to
FF).
@end table
@node Examples
@chapter Example invocations
The simple case is that you just want change the hardware address of
the first ethernet network interface for a fully random one:
# @samp{macchanger -r eth0}
Long options are supported. The following change the MAC address for
another one of the same kind (for example, wireless):
# @samp{macchanger -a wifi0}
To execute this examples, the interface must be down, otherwise
@command{macchanger} will be exit with an error message.
