Well - what I "do" is my "newsreader" was written years ago on Linux
(mostly by Marek Novotny off of Usenet) which I had ported to Windows.
 
              telnet nntp.server.net 119

It's just a bunch of scripts which fetch articles and present them in a
gVim window (since it was originally written for vi editing on Linux).

That's one reason I treat everyone the same, which is I treat them the way
they treat me in the post I'm responding to, since I don't see headers.

The only way I know whom I'm conversing with is by the attribute line.

So people sometimes claim I am "mean" to them; but the reality is that I'm
just reflecting their attitude since I only know what they wrote to me.

That's why Frank, for example, says I'm nice to him sometimes, and not
others; but Frank doesn't realize it's HE who is inconsistent; not me.

When someone says something intelligent, that's all I see (as I don't
generally even look at the attribute line) - so I respond similarly.

If they say something stupid - well - that's all I see; hence that's why I
respond to them in the way that I do (I'm a mirror of their attitude).

I only see what THEY write; and I respond to them as they wrote to me.

Since the newsreader is just a bunch of telnet scripts, Marek wrote a way
to use encryption, which is where stunnel on Windows came in handy.
               telnet localhost 55563

That goes to Stunnel, but you MUST manually define the port ahead of time.
                stunnel.conf
                 [Mixmin]
                  client = yes
                  accept = localhost:55563
                  connect = news.mixmin.net:563
                  CAfile = ca-certs.pem
                  verifyChain = yes
                  checkHost = news.mixmin.net
                  OCSPaia = yes

I didn't write the scripts so I try to mess with them as little as possible
since they're been working for maybe two decades (not counting the years).

But if I had wanted to get rid of stunnel, I suspect I could change them to
use openssl since that doesn't require me to deal with the high ports.
  openssl s_client -connect news.mixmin.net:563

Anyway, the problem of Hyper-V locking up ports has been happening for a
couple of years, but it was hard to debug because not only did a reboot
always fix it, but nothing was ever using the ports since I wasn't using
Hyper-V. Hence the "solution" was to disable Hyper-V in my case.

If people need to use Hyper-V, then they *must* reserve ports they want to
use *ahead* of time since Winnat reservation is essentially random (AFAIK).

This is all very easy to do.
If you know that you need to do it.

Which is the reason for my public service warning to everyone else.
I'm always trying to help people as I'm one in a million that way.
