Well, you say "of course", but it wasn't obvious to me at all. I
saw the server listening on port 30525, as I configured it to do,
so my assumption was that I could simply connect to that port, as
with any other Inet service. (Even though the host/port:db syntax
is a bit weird compared to host:port/db, but it's still pretty
good compared to other data source names, or connection strings.)

Unable to complete network request to host "localhost".
Failed to locate host machine

And this error message isn't exactly leading you to the issue..
