AREDN Announces Release of Second Beta, v3.15.1.0b2

 
On July 3rd the AREDN Project posted a second beta release of its upcoming v3.15.1.0 software.  It can be found through the Experimental Builds link on the Software Downloads page.  While you are encouraged to download it and report any issues, direct support for this release is currently only provided to AREDN Beta Testers.  Due to the potentially unstable nature of beta software, it should not be deployed in production networks.

If you are already on 3.15.1.0b01, then you can easily use the OTA (Over the Air) "keep settings" upgrade!  Joe (AE6XE) did his first 5+mile remote-over-RF upgrade and saved an afternoon and a long uphill hike (This was on a Ubiquiti 3Ghz node).  We've had some great feedback on the "part 97 only" channels where they have significantly improved link quality results

In addition, these are 'clean' image upgrades that minimize memory usage.  Whenever  'patch' files are used on nodes, this is a memory additive process.  In other words, a replaced file still has old file on the node in addition to the new the file.  These BOTH consume precious system memory.   The OTA upgrade, on the other hand, behaves as if you did a TFTP "clean" image load, but also pulls the config file settings across the upgrade!  It's a VERY COOL timesaver.

For those of you with tunnels, you will need to go into the Admin interface...

​AREDN Team at Ham-Com 2016

The AREDN team will be present at Ham-Com 2016 in Irving, Texas on June 10 and 11. 

At 12:00 noon on Friday in room 4, Conrad KG6JEI will present an overview of the Amateur Radio Emergency Data Network project and how it can help you meet the growing need to  transmit large amounts of data efficiently over Amateur Radio. The talk will be followed by a discussion and workshop at which team members will demonstrate various aspects of the current software.

We plan to run the workshop again on Saturday. We are scheduled to be in Room 9 again from 13:00 to 14:50.

We are looking forward to seeing you there and answering your questions.

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.
  5. ...

Operational Notes for AREDN™ 3.0.2

 

Inter-mesh Tunneling

VTUN can be real useful in connecting mesh islands across non-mesh networks, such as the Internet or other private IP networks.

For instructions on setup and configuration, see the article on AREDN.org

Additional things to remember when using tunnels:

  • The OLSR protocol runs over the tunnel, so mesh networks on the other end of the tunnel appear to be directly connected to your local mesh.
  • Only the Client or Server may be installed on any given node.
  • Nodes still running 3.0.0 which are connected via RF to a tunnel server or client may not be able to access the Internet at their local node unless they update to 3.0.2.
  • Internet gateway traffic across the tunnel is blocked by design.   It is a decision for the local mesh Administrators to coordinate if it is appropriate or not for their local users to have an advertised internet gateway.   A tunnel, if the only path of connection, may be used to divide nodes on a mesh and isolate who has and does not have Internet access.   To avoid routing failures, if a given mesh...
