  So... what did you try?  What was the result?

  We're not mind readers or magicians.  If your question is "I did stuff, but it didn't work".  The only real response is "do different stuff".

  If you post detailed questions which explain things, we can give detailed answers.

  As for the debug output...

  No, that is NOT what the documentation says to do.  Go read raddb/sites-available/coa

  This is fully documented.

  You will note that the server doesn't actually *do* anything.  There's no output that it's processing the packet, running modules, etc.  This should be a strong hint that the configuration is completely broken.

  Read the documentation.  Do what it says.  It will work.
