Again sent earlier. Thanks for the intervening comments about
vulnerabiliteis and versions.
A lot of issues and suggestions have been made and raised. My brief
response is that yes, according to nmap and my intention I had port 23,
for ssh (I moved it) and port 5900 open and the rpc port, I think. I'm
going by memory.
Theoretically the only pinhole in the ISP router firewall was port 23.
To use port 5900, you had to use an ssh tunnel.
My web server is on another machine. Since I only use it for
development, I don't leave it up.
My actual web pages are hosted externally on a vendor's box.
My experience with the upgrade treadmill is that it is a waste of time.
By its own admission (if a concept can have that) the new versions will
have issues and you need to upgrade. If the issues with an older
version don't affect you, then it is perfectly fine to use it. Why
upgrade and risk the fact that the new issues will affect your use case.
The developers for Fedora 13 were no smarter or dumber than the
developers who are writing Fedora 36. Or pick your distro of choice.
The issue with an older release is that nifty new things come out and
you can't really use them. But, if you run a VM with a recent version
of the distro, you can use them just fine.
The other issues is that if you are getting vendor support, they can
only reasonably commit to supporting a limited number of versions.
This is AMD hardware from '06.

"There are two ways of constructing a software design. One way is to
make it so simple that there are obviously no deficiencies. And the other
way is to make it so complicated that there are no obvious deficiencies."
