Starting a new thread because this observation is not intended to help with the "stealth" testing of port 113 from just above.
Nevertheless, it seems to me (an ordinary, everyday user) that to understand, at a user level, the business of internet security one must be an EXPERT on who are the EXPERTS! Frankly, I can't tell anymore.
I have no recommendations. I have no solutions.
And I don't know enough to know whose guidance to follow. All in all, a very frustrating situation for me and many other "ordinary, everyday users."
