​ARRL Awards 2018 Microwave Development Award to AREDN Team


​The ARRL announced that The Amateur Radio Emergency Data Network (AREDN) project team was named as recipient of the 2018 ARRL Microwave Development Award for its initiatives to utilize Amateur Radio’s microwave bands. These included extending the network’s high-speed multimedia capabilities from solely 2.4 GHz to 900 MHz, 3 GHz, and 5.8 GHz, and adding 802.11n protocol to improve data throughput. The Board also acknowledged the efforts of the many AREDN implementation groups around the country who are building networks based on this technology and who stand ready to utilize them to serve the needs of their communities in times of disaster.

​AREDN Project Announces Strategic Changes

AREDN forms a non-profit corporation to ensure continuity

The project saw the need for more formal governance and as a result, took the strategic step of organizing as a non-profit corporation.  This will help protect the user-community investments in mesh networking by setting up the framework for long-term resource management, research, and development. 

Our mission is still focused on providing the Amateur Radio Community with software, education, and support to enable them to aid public safety, emergency response and disaster relief agencies with high-speed multimedia data networks.

Continuing to rely on the financial support of a few individuals is not a sustainable means of supporting the project. Without more widespread support, the community’s growing investment in network equipment and relationships with served agencies is at risk. We expect to obtain contributions primarily from the ham community. We plan to use these funds to cover operating expenses such as web site hosting, setup a test and validation lab, obtain associated test equipment, and address the costs of promoting the project through various marketing channels. We plan to consider grants to fund worthy implementations of AREDN infrastructure as our resources may allow.

Installation Instructions for Mikrotik Devices


Download the Mikrotik .bin and the .elf file from downloads.arednmesh.org location:

  •  elf  :  this is the image to boot the mikrotik device with.  It only uses RAM on the device (which is lost with a power cycle and still boots with Mikrotik OS)
  • .bin :  once the device is booted with the .elf image and running,  copy this up to /tmp and type a command that will update the flash with AREDN, so it then boots AREDN on a power cycle.
 
The procedure is very different and it is the opposite of a Ubiquiti installation.  Opposite in that with Ubiquiti, the device is a tftp server and the tftp client is run on the laptop to send up the image.  With Mikrotik, the device is a tftp client and the laptop has to be configured to run a tftp server (also dhcp and bootp server)  on a linux or windows machine.    This is all done by a program called dnsmasq (it has all 3 servers).  
 

Linux procedure:

 
  1. Create a directory on your laptop /tftp ...

​AREDN 3.16.2.0 Release Notes


The AREDN Development team has incorporated significant security improvements and fixes to sustain the 3.16.x.x release line. 
The changes in the 3.16.2.0 release addresses: 

  • OLSR security vulnerabilities.  Mesh nodes were prone to attack or unintended consequences through access to OLSR information plugins on ports 9090, 2004, and 2006, commonly used to crawl the network to create map information.  Nodes could become unstable and/or unresponsive.   Please note that all prior versions of AREDN and BBHN firmware are affected.

  • OLSR instability.   Removal of the OLSR “httpinfo” plugin and the corresponding “OLSR Status” button on the status page.   The httpinfo plugin is not written to scale sufficiently to the larger mesh networks and cause OLSR to crash-restart.   Access to OLSR information is available using the jsoninfo plugin on port 9090 across the network.  Enter the following URL in a browser window to display the OLSR information: http://localnode:9090/all.    This command may not work in all browsers.  ...

Request to Testers for Release Candidate 3.16.2.0RC1


The AREDN development team has completed significant improvements to the current stable firmware. Several security fixes are now in place.
The changes in this release include:

  • Security vulnerabilities in various OLSR plugins are fixed. Please note that all prior versions of AREDN and BBHN firmware are affected

  • Removal of the OLSR “httpinfo” plugin and the corresponding “OLSR Status” button on the menu. If you need to get the OLSR data, use the OLSR jsoninfo plugin on port 9090

  • Added device protection from bricking if running AirOS 5.6+ when updating to AREDN.  Now you can simply TFTP AirOS back onto the device and downgrade properly before upgrading to AREDN

You can download the 3.16.2.0RC1 firmware here

Please report any issues to the AREDN GitHub and indicate that your issue is on v3.16.2.0

Operational Notes for AREDN™ 3.15.1.0

Before flashing a Ubiquiti device that is running or has been running AirOS version 5.6, please run the AREDN U-Boot Test program below before attempting a firmware load or upgrade.
 
We have developed the following utility to help you determine if your device is compatible, as well as being able to take a BACKUP of your node’s critical partitions
 
Download and run the AREDN U-Boot Test Setup Program.   If the test results in a "GOOD/GOOD" result, then you may proceed to load the appropriate AREDN firmware onto it. 

If the test results are "BAD," then you should do the following:
 

  1. Backup your device partitions using the AREDN U-Boot Test program.
  2. Use the AirOS GUI to downgrade to AirOS v5.5.x. 
  3. Re-run the AREDN U-Boot Test program and look for a "GOOD/GOOD" test.
  4. If "GOOD/GOOD", you can safely use the AirOS GUI install AREDN firmware....
