[x3d-public] python, node web servers listen on all interfaces

[John Carlson]

Just a note to follow up:

node and python web servers listen on all interfaces without careful setup.  Thus you shouldn’t start a node or python web server without looking
carefully looking at how to configure it for localhost only.

$ python3 -m http.server
Serving HTTP on 0.0.0.0 port 8000 ...
