OpenWrt Overview

Introduction

  • The intended audience of this page is someone who is familiar with Linux but new to the OpenWrt world.
  • OpenWrt is a very popular project that allows you to build your own Linux based firmware which you can use on embedded devices.
  • There are pre-built firmware available for many hardware models.
  • You can also compile your own custom firmware using the SDK (Software Development Kit)
  • Without duplicating existing documentation you can visit the project's website here: https://openwrt.org

OpenWrt with MESHdesk and APdesk

  • MESHdesk and APdesk makes use of OpenWrt.
  • It simply adds three additional items to it.
    1. The MESHdesk package.
    2. The MESHdesk Luci application.
    3. Some additional files e.g. a custom banner and logo.
  • Although we will cover these items later again when we do hands-on compiling, going through them in the overview will make things a bit more familiar later on.

MESHdesk package

  • OpenWrt follows the same pattern as most other Linux distributions where it has a package manager (opkg) that is used to install software onto the device.
  • This package manager also takes care of dependencies.
  • Packages can be installed after the device is flashed and running with OpenWrt or it can included during compile time to be part of the firmware.
  • We will compile our own OpenWrt firmware that have the MESHdesk package included later on.
  • When you build your own OpenWrt firmware you make use of the OpenWrt SDK (Software Developer Kit).
  • The OpenWrt SDK allows you to:
    • Select the specific device you want to build firmware for.
    • Select the packages you want to include with the firmware.
    • Include your own additional files with the firmware.
  • This is exactly what we will be doing later on.

MESHdesk Luci package

  • OpenWrt can work fine without any web interface.
  • There is however a web interface available called Luci which is an add-on to plain OpenWrt.
  • The firmware which you can download from the OpenWrt website has it included by default.
  • The nightly builts of the development branch however do not have it included.
  • Luci has various sub items e.g. modules, applications, themes etc.
  • We will add an application to Luci (the MESHdesk Luci Application)
  • This application will allow someone to enable or disable central management of the OpenWrt device using the Luci web interface.
