Hello Cant get my head around this:

Has it something to do with Python version and event handling or anything else. Best regards

What happens if you run adsbcot manually? and if you're using a custom config, can you share that?

Jun 27 '23 16:06 ampledata

I disabled the service and ran: adsbcot This is what happened. (I'm running on Rocky Linux 8)

[root@localhost ~]# adsbcot 2023-06-28 09:43:05,926 pytak INFO - CoT_URL Dest: udp://239.2.3.1:6969 2023-06-28 09:43:05,926 pytak INFO - Run: <class 'pytak.classes.CLITool'> 2023-06-28 09:43:05,930 pytak INFO - Run: <class 'pytak.classes.TXWorker'> 2023-06-28 09:43:05,930 pytak INFO - Run: <class 'pytak.classes.RXWorker'> 2023-06-28 09:43:05,930 pytak INFO - Running <class 'adsbcot.classes.ADSBWorker'> 2023-06-28 09:43:05,930 pytak INFO - Complete: <Task finished name='Task-4' coro=<ADSBWorker.run() done, defined at /usr/local/lib/python3.11/site-packages/adsbcot/classes.py:146> exception=FileNotFoundError(2, 'No such file or directory')> Task exception was never retrieved future: <Task finished name='Task-4' coro=<ADSBWorker.run() done, defined at /usr/local/lib/python3.11/site-packages/adsbcot/classes.py:146> exception=FileNotFoundError(2, 'No such file or directory')> Traceback (most recent call last): File "/usr/local/lib/python3.11/site-packages/adsbcot/classes.py", line 189, in run inotify.add_watch( File "/usr/local/lib/python3.11/site-packages/asyncinotify/init.py", line 450, in add_watch raise e File "/usr/local/lib/python3.11/site-packages/asyncinotify/init.py", line 447, in add_watch wd = _ffi.libc.inotify_add_watch(self.fd, bytepath, mask) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/asyncinotify/_ffi.py", line 24, in check_return raise OSError(errno, os.strerror(errno)) FileNotFoundError: [Errno 2] No such file or directory: PosixPath('/run/dump1090-fa')

I guess in this case it just uses defaults? Not any config parameters?

Jun 28 '23 07:06 taksalo

Hey @taksalo. The default behavior is to read decoded ADS-B data from the filesystem at /run/dump1090-fa/aircraft.json. See: https://adsbcot.readthedocs.io/en/latest/config.html

To change this location, or to use another method to read the ADS-B data, you'll need to set the FEED_URL parameter, see: https://adsbcot.readthedocs.io/en/latest/config.html#example-configurations

Ok thank you very much for the help so far. I'm running dump1090 on the same server and tried [adsbcot] COT_URL = udp://239.2.3.1:6969 FEED_URL = http://127.0.0.1:30002

Seems to be working better, output is now [root@localhost ~]# adsbcot -c /etc/adsbcot.ini 2023-06-30 10:11:44,650 pytak INFO - CoT_URL Dest: udp://239.2.3.1:6969 2023-06-30 10:11:44,650 pytak INFO - Run: <class 'pytak.classes.CLITool'> 2023-06-30 10:11:44,651 pytak INFO - Run: <class 'pytak.classes.TXWorker'> 2023-06-30 10:11:44,651 pytak INFO - Running <class 'adsbcot.classes.ADSBWorker'> 2023-06-30 10:11:44,651 pytak INFO - <class 'adsbcot.classes.ADSBWorker'> polling every 3s: http://127.0.0.1:30002 2023-06-30 10:11:44,652 pytak INFO - Run: <class 'pytak.classes.RXWorker'>

I will try to get the TAK server to view the CoT messages. Havent got so far yet.

Ok, I think you might be confused about the FEED_URL parameter. Currently you're using http://127.0.0.1:30002, however, the 30002 port should use a URL like: tcp+raw://127.0.0.1:30002 or tcp+beast://127.0.0.1:30002.

Jul 02 '23 21:07 ampledata

Ok, thanks again. Since I didnt install with raw or beast support I will try using:

FEED_URL = http://localhost:8080/data/aircraft.json or the json file if i can locate it.
