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.

Release notes for recent AREDN nightly builds

The AREDN devs continue to crank out changes to the AREDN code base.  Here's a summary of what's been happening in the recent nightly builds:

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
  • Enabled  negative channels for 2.4 GHz 802.11ac devices
  • Fixed negative channels not beaconing.
  • 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...
