AREDN at SCALE 20x


For the last few years, AREDN has had a booth on the expo floor at SCALE, the Southern California Linux Expo.  It's happening again at the 20th annual SCALE, March 9th through 12th (https://www.socallinuxexpo.org/scale/20x), at the Pasadena Convention Center.  The Expo runs from Friday afternoon until Sunday afternoon, and the AREDN booth will be manned with knowledgeable AREDN users, including Tim KN6PLV, one of the principal AREDN developers. The booth dudes will be happy to chat about all things AREDN with you!

AREDN is derived from OpenWRT, which is a Linux "distribution". As you get into AREDN networking, it's helpful to know a bit more about Linux.  SCALE will be holding Linux training classes on both Saturday and Sunday.  After installing Linux on your computer of choice, a professional trainer from the Linux Foundation will guide you through the basics of Linux and system administration.

If you're interested, you can register for the training class when you register for SCALE itself.  Don't wait too long; the classes tend to fill up quickly.

Be sure to say hello to Orv W6BI and Tim KN6PLV.

Devices added back into the nightly build after recent big OpenWrt update:

  • Mikrotik LDF 5
  • Ubiquiti AirRouter

Bug fixes

  • Fixed WAN VLAN detection on hAP
  • Fixed idle tunnel quality check
  • Fixed IBSS (Independent Basic Service Set) problem on 2.4GHz

  • Fixed PowerBridge M upgrade

Enhancements

  • Merged openwrt release 22.03.3
  • Added a maximum timeout for service checks
  • Made the default country HX (HAM)
  • Improved the quality of the scan output
  • Improved idle tunnel quality measurement
  • Provided better error feedback when upgrades fail
  • Tagged those devices which must be reinstalled.   (The NAND layout for a few Mikrotik devices has changed sufficiently that they cannot be easily upgraded and must be reinstalled from scratch.)

Over and above the neighbor status states of pending, active , etc., new states of "hidden" and "exposed" have been added.  

Because the nodes talk amongst themselves, your node knows...

Release notes for AREDN nightly build 2017 and later

 

Nightly build 2017 is based on the latest OpenWRT release, version 22.03.2. (The current AREDN production release is based on OpenWRT 19.07 from January 2020). 

There are significant changes in this nightly build:

  • All devices have been moved to the ath79 device tree (no more ar71xx).

  • The ipq40xx device tree has been added.

  • Each device now has its own image file.

  • Some filenames have been changed.

 

As a result devices need to be tested carefully, at least initially.

 

The most current status on nightly builds can be found in the README file here:

http://downloads.arednmesh.org/snapshots/readme.md

 

While this release has been tested on more than 90% of device types active on AREDN networks, it could not be tested on everything and support for some devices is either untested or not readily available. If you need a nightly build that’s missing please let us know and we will add it if possible (but you will need to provide hardware for development and testing).
