if there's no server running that's listening on port XXXX, then
the OS has nowhere to forward any connection request to. That
triggers the ¡°actively refused¡± response from the OS.
Anthropomorphically, It's as if you've gone to some street address
and asked to speak to someone who doesn't live there.
For security reasons, the reply is usually exactly the same
whether the required server/d?mon is not installed, is not
running, or the server/d?mon is running, but the request has been
blocked for some reason.

Thanks Robin,
So it's not the server app that's "actively
refused" the request but the OS the app is running on. I'll
bear that in mind when I next drill down into my remote
