  I would suggest not explaining basic networking.  Since I work with
FreeRADIUS && UDP networking daily, you should presume that I have some
minor understanding of it.

  No.  That is not how networking works.

  I explained.  Did you read and/or understand it?

  And "man netstat" might be useful, too.

  In any case, this list is not the place to discuss netstat, or why you
