AREDN production release 3.22.6.0  is now available


AREDN production release 3.22.6.0 is now available.  This is the release you've been looking for :-)

Since the last production release, there have been 136 separate ‘pull requests’ in the AREDN github repository.   Those requests pulled these significant improvements and new features into the AREDN software:
1. The conversion from Perl programming to Lua is complete - the result is a significantly smaller, somewhat faster, code base.

2. Due to the recovered space in the image, tunnels are now always installed, so nothing needs to be done with them during future upgrades.

3. After this upgrade, future upgrades should be much more reliable, especially on low memory devices.

4. Tunnels will be prevented from accidentally connecting over the mesh.

Tunnels normally connect via the WAN interface, that being the point of the things. However, if the WAN interface on a node goes down for some reason (the tunnel server/client Internet fails) the node will select a new way to talk to the Internet by first routing over the Mesh. When this happens, tunnels could end up being routed partially over the mesh, which is bad because tunnels are also part of the mesh. So, we now prevent this by default by adding a firewall rule.


5. You can now adjust the poll rate for alerts....

Link Quality Manager (LQM)

 

Thanks to recent developments by Tim KN6PLV, we are introducing a new tool to help manage AREDN networks.

Nightly Build 1265 contains a number of improvements broadly called Link Quality Management. It’s designed to make the AREDN network more stable and improve the available bandwidth. Tests with these changes have shown improvements from modest to close to 200% in link throughput, tested end to end with iperf3.

Documentation is here

Nightly Build Reminder

The AREDN team greatly appreciates all of the testing of the nightly builds as they roll out and introduce the new code base and features. We are paying close attention to your reports of successes and problems found.

Just as a reminder:
IMPORTANT NOTE:  While AREDN encourages you to download, install and test the nightly builds and report any issues found,  DO NOT install them in any node that doesn’t have easy access (e.g., towers, water tanks or mountain tops).  By definition nightly builds are not to be considered production grade software.

AREDN Development Plan 2022


Following their recent code production release, AREDN has embarked on an ambitious development plan.  Here’s a basic overview of what is on their plate

Replace Perl code with Lua

The programming language for the user interface, services and many other functions is written in Perl.   The Perl libraries are very large and AREDN has embarked upon a project to replace it with Lua, a much lighter weight programming language designed to run in embedded devices.  

In steps, the team will update the “read-only” page to Lua: 

Main, Mesh Status, etc.

Then the read-write pages will be updated: 

  • Basic Setup     

  • Port Forwarding DHCP and Services     

  • Tunnel Server

  • Tunnel Client

  • Administration     

  • Advanced

  • Configuration

  • And some others

 

Resync with OpenWRT

Then the code base will be updated to OpenWRT 21.02.1.  Besides code enhancements and security fixes, it brings in:

  • ...

AREDN at Winterfest 2019


AREDN mesh networkers will be at the Winterfest 2019 in Vienna, VA on Sunday, March 24, 2019. The hamfst will be held at the Northern Virginia Community College Annandale Campus. Click here for directions.

A group led by Damon Schaefer K9CQB will be on hand to demonstrate equipment and answer your questions. Just look for the large AREDN banner at their table. His team plans to populate the booth with several masts bristling with equipment and 2 large monitors, one running an AREDN slideshow and one with a local mesh network for live demonstrations. 

Stop by and say hello!

The indoor exhibit space can accommodate 100 vendors and there are 150 paved outside tailgate spaces. Click here for more information.Admission for everyone, vendors and the general public, begins at 6 AM, Sunday. The admission fee is $10. For table and tailgating spaces, see the...
