Rbfeedr with piaware

kmm0000 · December 1, 2023, 8:53pm

Why does running rbfeedr with piaware results in much higher message rate in skyaware / tar1090?

caius · December 2, 2023, 11:39am

It’s feeding messages back into dump1090 so they are being counted twice. I’m not sure what causes it exactly but there’s something about the rbfeeder setup that can cause it. Double check for it connecting back to the input port of dump1090 in the rbfeeder config.

Not really seeing much in the rbfeeder.ini

network_mode=true
[network]
mode=beast
external_port=30005
external_host=localhost

[mlat]
autostart_mlat=true
#mlat_cmd=/usr/bin/python3.9 /usr/bin/mlat-client

And the S/N, key, lat, long, elevation

I did notice rbfeeder opens ipv4 connection on 30005

A possiblity is malfunctioning mlat-client supplied and installed from RB24 repository by command sudo apt install mlat-client.

To test, uninstall it by command sudo apt purge mlat-client, then REBOOT Pi and check if the excessive high message rate has normalized.

If you find that removal of the RB24 supplied mlat-client has solved the problem, then do NOT reinstall it by command sudo apt install mlat-client. Instead build and install it from source-code yourself. It is very easy and takes only few minutes:

sudo apt update 
sudo apt install -y git curl build-essential debhelper python3 python3-dev dh-python  

git clone https://github.com/mutability/mlat-client.git  
 
cd mlat-client  
sudo dpkg-buildpackage -b   

cd ../  
sudo dpkg -i mlat-client_*.deb

Next put mlat-client built by you on hold, so that it does NOT get replaced by RB24 supplied mlat-client during update/upgrade:

sudo apt-mark hold mlat-client 

sudo reboot

What I thought would be a quicker test

I stopped mlat-client

Confirmed it was off Active: inactive (dead) since Sat 2023-12-02 09:47:19 EST; 6min ago

No change in the high message rate

stopped rbfeeder on the the piaware host where I’m seeing the high message count, it drops back to normal.

Installed rbfeeder on another host that’s not running any other adsb apps and pointed it to the piaware host.

Instant jump in messages on the piaware host when I start rbfeeder on the other host.

There’s clearly some output loop going on.

Piaware I believe uses 30005 for host data source?. If rb feeder is opening that too, and spitting mlat results out of if you could expect a similar outcome

Is one of the reasons the likes of fr24 told everyone not to feed them if they do others. As multiple clients can share the same

Time to check the fa cmline and ensure it’s the sole source and switch off some of the rb options.

Perhaps it is requesting Mode A/C data?

kmm0000 · December 3, 2023, 9:33am

Bingo.

That lead me to this thread - Dump1090 - Message rate too high in Skyaware - #32 by wiedehopf

Confirmed mode a/c messages with jq < /run/dump1090-fa/stats.json ‘.total.local’
disabled mode a/c in piaware-config.txt allow-modeac no
restarted dump1090-fa and rbfeeder, no more high message rate in skyaware/tar1090

For package install of dump1090-fa added EXTRA_OPTIONS=“–no-modeac-auto”
