efeu - HomePlug AV Packet Reflector



efeu - HomePlug AV Packet Reflector


efeu [options]


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.


-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.


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.


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.


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 ˆC or ˆZ 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 ˆC or ˆZ at the console.

# efeu -v -i eth4 > efeu.log
