Hello Alan,

Here is my rbfeeder.ini (key, latitude and longitude redacted):

Code Select Expand

[client]
lat=MASQUE
lon=MASQUE
alt=353
network_mode=false
log_file=/var/log/rbfeeder.log
key=MASQUE
sn=EXTRPI736563

[network]
mode=beast
external_port=30005
external_host=127.0.0.1

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

[dump978]
#dump978_enabled=true

Thank you for your help.

Hello Alan,

Following the AirNav support link (Trixie guide by abcd567), here is what I checked on my Raspberry Pi 4, Raspberry Pi OS Trixie, rbfeeder 1.0.17, network_mode=false:

- python3 3.13.5; "import asyncore" works (python3-pyasyncore 1.0.2-3 installed).
- mlat-client 0.2.13+trixie1 is installed from the repository (not compiled by me); no package on hold.
- /usr/bin/mlat-client --help runs normally.
- No error related to mlat, asyncore or Traceback in journalctl -u rbfeeder, and nothing about mlat in /var/log/rbfeeder.log.
- The only error at service start was ExecStartPre setfacl status=203/EXEC (acl was not installed). I installed acl: now status=0/SUCCESS. No change for MLAT.
- I tried [mlat] with autostart_mlat=true and mlat_cmd=/usr/bin/python3 /usr/bin/mlat-client; then both commented out; then enable=true. After each rbfeeder restart (waited 5 minutes), "ps aux" shows only dump1090-rb (started with --mlat --forward-mlat --gnss). No mlat-client process is ever started.
- Position (lat, lon, alt=353) is set in rbfeeder.ini and on the website. Station serial EXTRPI736563.

Questions: is MLAT perhaps not enabled for my station on the server side? Which exact condition makes rbfeeder start mlat-client? Is there a debug option to make rbfeeder log why it does not start it?

Thank you for your help,didou

MLAT is enabled when you add your exact lat/lon and altitude on the grid of your map

I have very little Linux knowledge but note that your mlat on the ini file is different from the one shown by the reply previous to yours, it reads

[mlat]
#autostart_mlat=true
#mlat_cmd=/usr/bin/mlat-client
enable=true

Try changing yours to that

Hopefully abcd will note the conversation and help out
