Not working on Windows

[albsantosandres]

Dear colleague, I am trying to run your OSNMA code using the following SW:

• Windows 10 Pro
• Python 3.10.0, 3.10.6 and 3.10.7
• Data source: Galmon I properly download the dependencies in the requirements.txt file ... but I always get the following output (even waiting 30min) with no additional information . However my brother succeeded to get authentication information with a MAC. Have you got similar problems?

_``` _H:\osnma\OSNMA-master\live_galmon_run>python run.py Running using GALMON live data. INFO - Start status COLD_START

WARNING - Cannot compute Padding length: Missing attribute NB_DP INFO - Public Key 2 read. Start status WARMSTART

Hello!

Thank you for your interest on the software!

Have you tried running the custom_run folder? It comes already configured with an SBF file. If that runs, then the problem is probably related only with the galmon input.

If that's the case, can you try running this command in the command line?

nc 86.82.68.237 10000

I don't know the equivalent tool for windows (it is called netcat on linux). It basically opens a TCP connection with the host serving the galmon data.

If you don't see a bunch of characters printed on the console, that means your network is not able to access galmon.

If you see characters printed on the console, then I would ask you to uncomment these two lines in the galmon input file and show me what you get :) (you can also do that right away if you are not comfortable with running the previous netcat commad)

Happy new year!

Just another question: are you running from the last release or have you clonned the repo?

I did some changes to improve the galmon input that I haven't added to any release, so I would recommend you to test it with the cloned repository

Hi again, Thanks a lot for your prompt reply. Find below my answers: 1) The custom_run works properly and I can see the authentication outputs. 2) I have tried a telnet command (equivalent to nc) to the indicated IP and port and it works properly as I can see binary data output. 3) In the previous try, I download the zip. Now I cloned the repo but it still fails. 4) Requested output after uncommented lines:

During handling of the above exception, another exception occurred:

For the provided error, It sounds to be a Windows issue when managing the socket. Maybe I will try using Linux.....

[Algafix]

Thank you for checking it!

It seems an easy-to-reproduce error, maybe windows doesn't like the socket.MSG_WAITALL . I'll configure the windows VM and work on a fix this weekend :)

Hello! I just pushed a fix for the galmon input.

Let me know if it works for you :)
