Thanks.

That is preferable. That is actually why I made the change. So that no
editing or setting or properties was needed by default, unless you
needed a set different from the public defaults.

Yes, making this as easy as possible for anybody running the tests, so
in principle you don't have to changed or edited anything was the goal.

So the real changes are just to use one standard (echo) port to make it
easier to switch hosts. Make cname.sh not use a hardcoded host. And then
set the defaults so that they work for everybody out of the box against
a set of publicly available machines. Then only people needing to do
tests against non-public machines have to change any settings.
