Command line tools for simple IEEE Std 1722.1-2013 messages Copyright 2014 By J.D. Koftinoff Software, Ltd. www.jdkoftinoff.com jeffk@jdkoftinoff.com

Overview

This source package when compiled builds the following command line tools:

  • avdecc - general message generation
  • avdecc-discover - trigger discover of entities
  • avdecc-read-descriptor - read a specific descriptor from an entity
  • avdecc-get-control - get a control's value from an entity
  • avdecc-set-control - set a control value on an entity

Getting the Source Code

git clone https://github.com/jdkoftinoff/avdecc-cmd.git --recursive
cd avdecc-cmd

Using avdecc-cmd as a library in your program

Linux

  • Add the directories jdksavdecc-c/include and include to your compiler's include path
  • Add all C files from jdksavdecc-c/src and src to your project

Mac OS X

  • Add the directories jdksavdecc-c/include and include to your compiler's include path
  • Add all C files from jdksavdecc-c/src and src to your project
  • Link libpcap to your project by passing -lpcap on the linker command line

Usage

All programs need either root/administrator access or the appropriate capability set to access raw ethernet frames via the desired ethernet driver.

All programs have the following common first 3 parameters:

  1. verbosity - A number either 0, 1, or 2
  2. timeout_in_ms - The number of milliseconds to wait for a response
  3. network_port - The ethernet port to use

For example, running avdecc-discover on linux:

avdecc-discover 2 1000 eth0

or on Mac OS X:

avdecc-discover 2 1000 en0
