The AREDN simplified firmware filename standard has been changed to the default OpenWRT convention to leverage data files created at build time for future automation of firmware selection.
When installing this firmware release, from prior firmware versions, you may get an error message similar to
“This filename is NOT appropriate for this device.“
“This device expects a file such as: aredn-3.22.1.0-main-ef2d605-ubnt-nano-m-xw-.*sysupgrade.bin”
“Click OK to continue if you are CERTAIN that the file is correct”
Ensure that you are loading the correct file by referring to the downloads page, then safely ignore the warning. Once this release is loaded, this error message will never occur again.
When the size of the hostname and service advertisements exceeded the size of a single network packet, only IP addresses would be known. The...
"PARDEN" the interruption! October's Meshoween network test was so successful that, we've decided to celebrate with another one at the end of the year. We'll celebrate New Nodes Eve and then Happy Mesh Year!
Seriously, this is an opportunity to stress the network again after the router storm mitigation patch has time to promulgate throughout the network. Meshoween also revealed an issue with the performance of the Mesh Status page when the node count got high. Both these patches were published in nightly builds in early November. If your node's running a nightly build later than that, you should be good to go.
The WWL - "World Wide Linkup" will start at 000Z on 1/1/2022 (afternoon of the 31st for the U.S.) and last at least 4 hours. If you've brought up a tunnel that you don't normally use, feel free to drop it anytime after 4 hours.
So crank up those tunnels and be on the lookout for network wierdnesses.
We are considering how the future version of AREDN mesh network software might affect the use of the Meshchat application.
Please help us by responding to the Meshchat poll here.
Note - this report is written from a Southern California perspective. Depending on your location, as they say YMMV!
During the test the node count on the linked networks locally rose to around 1,090. N2MH's N2MH-Hub saw 1428, most likely a record for an AREDN network.
Observations:
As we hoped, network storms never appeared from our West Coast point of view, and none have been reported to date. Network traffic was not substantially higher than normal. Using KN6PLV's Mesh Monitor, messages per second were averaging about 600 before the test. During the test it hovered closer to 700. Most of the increase in traffic was due to OLSR routing broadcasts, which each node has to handle.
As we expected, older devices struggled. Many wound up with a load significantly greater than 1 (which is a full load for a single-CPU device like these), indicating their CPUs were struggling to keep up with their pending processes. Ssh'ing into a few of them and running top showed that with node counts around 1,000, loads of around 4-5 were seen.
Things we didn't expect:
While the slower nodes struggled with displaying UI pages, they were usually still able to pass traffic. But occasionally that older hardware bogged down so much that it couldn't. Perhaps some effort should be made to prioritize traffic handling...
