​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.

AREDN code repositories on GitHub

The AREDN source code repositories are now accessible on GitHub at https://GitHub.com/aredn/aredn_ar71xx .   GitHub is one of the largest open source hosting services with over 40 million users.   Anyone with basic knowledge of Linux and git can now compile AREDN images and contribute changes.   If you have a background in application or firmware development, the hurdle to get started and contribute to the ham community is now much lower.

GitHub also includes an issue tracking feature to capture feature requests, bug reports, and other issues.  This immediately replaces our former defect tracking tool (Bloodhound).
 

​AREDN GitHub Activity

The GitHub setup is intended to jump AREDN forward to stay current, and benefiting from, the 1000+ developers of Linux and OpenWrt releasing a steady stream of advancements and fixes.    AREDN is now based on this stream.  By staying current, our community is able to focus on those features unique to the ham community.

The OpenWrt group produces a major release each year followed by 3 or 4 point releases in successive months.   The latest release candidate was published in June 2018 with a final release targeted in July.

hAP ac lite 5GHz LAN Access Point


Joe AE6XE reports that the  Nightly Build available on Nov 28, 2018 will now include capability to use both wireless cards in the hAP ac lite device.  The 2GHz is the Mesh RF and now the 5GHz is a standard part 15 Access Point bridged with the LAN network.   This means that LAN mesh devices can be both on wifi and physically on the Ethernet port, both allocated the IP addresses assigned for the LAN network.   

For now, the 5GHz channels overlapping Doppler Radar are not selectable -- the "DFS" channels.   This will be an add on later to integrate in these channels. 

The code changes that make this possible, also make the following capability readily doable and are in the pipeline for the nightly build:

1) Activating the Nanostation XM devices' secondary Ethernet port to be standard AREDN functionality (and daisy chain devices with poe passthough).
2) Ability to enable/disable the following for single wireless card devices -- only one active on the wireless at a time or both disabled:
     a) mesh RF as we know today
     b) LAN Access Point for...

Improved Capability on XW Device Ports

 

Full functionality of both ports on Nanostation M2 and M5 XW units is now available.

Joe AE6XE found a way to remove the limitations noted in the forum thread.   Both Ethernet ports on the Nanostation M2/M5 devices are now configured and working without limitations.  This code will be available after tonight's build on Nov 22, 2018.  Text included in the AREDN GitHub README:

The following devices have enhanced Ethernet port usage.

  • NanoStation M5 XW
  • NanoStation M2 XW

A single CAT5 cable to the device could be plugged into ether the 'main' or 'secondary' port with standard port functionality. Both ports can be used interchangeably and simultaneously with LAN devices on both ports at the same time. POE PassThough can be turned on in Advanced Settings to power IP cameras or other mesh nodes. It is passive' POE, which means whatever voltage you supply the M5 XW with, that voltage is passed though to the secondary port and device.  It could be between about 10....

California Hams Provide Fire Videos


Local amateur radio operators are responding to the recent and ongoing fires in California in many ways. Several of these hams have built a high-speed multimedia AREDN mesh network which was used to deliver live streaming video of the fires in progress.

In Ventura County, Orv Breach W6BI, Paul Straus WD6EBY and Ben Kuo AI6YR installed high-definition cameras in their portion of the growing Southern California AREDN network. They were able to figure out how to send to live video stream across the mesh network to then Internet and finally to YouTube for public access.

Ben AI6YR reports that their mesh network stayed operational even when the Spectrum cable, Internet access and phone system went down across the region. People were able to use the mesh network to keep updated on emergency information.

Ham Radio 2.0 Interviews AREDN Developers

Jason KC5HWB continues to produce a great series of ham radio videos on YouTube. In Episode 159, Jason interviews Joe AE6XE and Darryl K5DLQ from the AREDN development team. They describe the many improvements in the latest AREDN release version 3.18.9.0 and talk about the development process. They discuss the expanded list of supported devices which now includes the newer Ubiquiti AIrMax models and several units from Mikrotik.Joe and Darryl tell the viewers about our plans to provide a Raspberry Pi firmware installer which is being developed by K6RUN.

​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.  ...
