This might sound strange but I need to disable mlat (but keep everything else)

[tgo]

How do I do this, RB mlat doesn't play nice with other feeders so I need to lose the RB mlat and reinstall the more friendly one.


my rbfeeder.ini shows this

[mlat]
autostart_mlat=true
#mlat_cmd=/usr/bin/python3.5 /usr/bin/mlat-client

How would I go about just uninstalling/removing RB mlat?

I dont see why the mlat client causes issue, plenty of users have it working and are feeding other trackers without issues, hopefully some one familiar with Pi's will come along and assist

In the meantime have a read at https://forum.radarbox24.com/index.php?topic=101771.0

Change true by false as shown below

[mlat]
autostart_mlat=true  false
#mlat_cmd=/usr/bin/python3.5 /usr/bin/mlat-client

Save file.
Restart rbfeeder

sudo systemctl resrart rbfeeder 

[tgo]

Thanks, although I notice that this seems to think I'm on python 3.5, when I'm on 3.7 (or whatever the latest is)

#mlat_cmd=/usr/bin/python3.5 /usr/bin/mlat-client

The above line of code is commented-out (it starts with # ).
This means this line will be ignored during execution.

I also have raspbian buster which has python 3.7
To use this command, I did two things:
(1) Deleted #
(2) changed 3.5 to 3.7
(3) Saved file /etc/rbfeeder.ini
(4) Restarted rbfeeder
sudo systemctl restart rbfeeder

Thanks for that, so if it's commented out, what function does it serve when it's not, and what runs in its place when it's commented out.

Fantastic question and something I'm wondering myself as I try to troubleshoot my own MLAT issues. Sorry to bump an old thread, but can someone answer this question? Might end up helping me, too. :)

What MLAT issues are you having Jackal

Hi,

I think that python script located in /usr/bin/mlat-client should be modified by maintainers at the very 1-st line:

Code: [Select]

#!/usr/bin/python3.7
IMHO it should be just:

Code: [Select]

#!/usr/bin/python3
to avoid statically defined Python version. If Python will go higher version in the future, then the /usr/bin/mlat-client will know what to do :)

RaspberryPi OS has got symlinks (I'm still on "Buster" since RB doesn't support Bullseye yet):

1. /usr/bin/python - which links to symlink @python2 which links to python2.7 binary
2. /usr/bin/python3 - which links to python3.7 binary

mlat-client starting script is located in /etc/init.d directory

BTW, does anyone know when RB will upgrade their feeder to Debian Bullseye version?... ;)

i dont know the answer to your query but there is a workaround avilable to get the feeder working with Bullseye.  See https://forum.radarbox24.com/index.php?topic=105631.0

Modifying the mlat line is not necessary as the mlat line is commented out (i.e. starts with a # ) and therefore ignored during execution.

Actually it is the mlat-client which has the python version hard-coded, and uses that version of python.

Please note that mlat-client package for each distro (Stretch,  Buster,  or Bullseye) is built on that distro, and when installed & run, selects version of python suitable for that particular distro, and won't work on another distro.


The correct version of pyhon3 is automatically selected by the mlat-client as follows:

On Stretch,  it uses pyrthon 3.5
On Buster,  it uses pyrthon 3.7
On Bullseye,  it uses pyrthon 3.9

If you run command "sudo systemctl status rbfeeder", you will find following lines in the output:

ON STRETCH:
CGroup: /system.slice/rbfeeder.service
           ├─508 /usr/bin/rbfeeder
           └─596 /usr/bin/python3.5 /usr/bin/mlat-client --input-type dump1090 --input-connect 127.0.0.1:32457 --server mlat1.rb24.com:40900


ON BUSTER:
CGroup: /system.slice/rbfeeder.service
           ├─508 /usr/bin/rbfeeder
           └─596 /usr/bin/python3.7 /usr/bin/mlat-client --input-type dump1090 --input-connect 127.0.0.1:32457 --server mlat1.rb24.com:40900


ON BULLSEYE:
CGroup: /system.slice/rbfeeder.service
           ├─508 /usr/bin/rbfeeder
           └─596 /usr/bin/python3.9 /usr/bin/mlat-client --input-type dump1090 --input-connect 127.0.0.1:32457 --server mlat1.rb24.com:40900


The mlat-client is installed from Radarbox24 repository by following command

sudo apt install mlat-client   

There are two versions of mlat-client in Radarbox24 repository (1) for Stretch (2) for Buster.  The apt checks the version of OS,  and installs the matching version of mlat-client.  As RB24 have not yet released their rbfeeder for Bullseye, their repository not yet has mlat-client for Bullseye.

For ease of users, I have built mlat-client on Bullseye and uploaded it to Github. Those who install on Bullseye the rbfeeder which is meant for Buster, using workaround posted by me, can download and install mlat-client for Bullseye from here:
