Re: No response from localhost with "allow-query { any; };"

Hi Axel,

the `nc` commands you used for testing neither proves that
it’s that specific `named` listening on that port nor DNS
daemon at all.  FWIW it could be a dummy UDP/TCP server
and you would not know.

First you need to use a tool from your operating system
to check what is listening on those ports, and then use
`dig` (or other DNS debugging tool) to send actual DNS
queries.
