NAME

       efeu - HomePlug AV Packet Reflector

SYNOPSIS

       efeu [options]

DESCRIPTION

       Read  and reflect 802.3 Ethernet messages addressed to this host or the broadcast address.
       Do not display reflected frames.

       The program is one example of a simple packet listener.  Engineers and software developers
       can  extend  it  to  build  custom  sniffers  or  servers.   The  framework is present but
       additional features must be added.

       This program is part of the Qualcomm Atheros Powerline Toolkit.  See the plc man page  for
       an overview and installation instructions.

OPTIONS

       -e ethertype
              The  protocol (or ethertype) of interest expressed as a 16-bit hexadecimal integer.
              Prefix "0x" is optional.  This filters out frames having any other ethertype.   The
              default is ETH_P_802_2 as defined in if_ether.h.

       -i interface
              Names  the  host  ethernet  interface to watch.  The named interface, such as eth0,
              eth1 and so on, must be connected to a  HomePlug  AV  ethernet-to-powerline  bridge
              adapter to receive any HomePlug AV traffic.  The default interface is eth1.

       -q     Quiet mode.  Suppress the printing of the normal message descriptions on stdout.

       -t milliseconds
              Read  timeout  in milliseconds.  Values range from 0 through UINT_MAX.  This is the
              maximum time allowed for a response.  The default is 50 milliseconds.

       -v     Verbose mode.  Displays incoming frames in hexadecimal dump format on stdout.  This
              option is independent of option -a which prints VS_ARPC message text on stderr.

       -?, --help
              Print  program  help  summary  on  stdout.  This option takes precedence over other
              options on the command line.

       -!, --version
              Print program version information on stdout.  This  option  takes  precedence  over
              other  options  on  the command line.  Use this option when sending screen dumps to
              Atheros Technical Support so that they know exactly  which  version  of  the  Linux
              Toolkit  you are using.  See the HomePlug AV Specification for a description of all
              HomePlug AV message types.  See the Qualcomm  Atheros  INT6000  Firmware  Reference
              Manual for a description of Atheros Vendor Specific message types.

EXAMPLES

       The  following  command  monitors  the  default interface eth1 for HomePlug AV traffic and
       dumps detected frames on the console as they occur.  Terminate the foreground  process  by
       typing  ^C or ^Z at the console.  This program is usually run in a separate console window
       when performing other toolkit operations.

          # efeu

       The following command monitors host interface eth4 for incoming  HomePlug  AV  frames  and
       dumps writes them to file efeu.log.  Frames are printed in hexadecimal dump format because
       option -v is present.  Terminate the foreground process by typing ^C or ^Z at the console.

          # efeu -v -i eth4 > efeu.log
