Go into linux directory that has the files you want to serve.
Start the webserver in the directory of the files you want to expose:
$ python3 -m http.server 8321
Test it from another machine by using a web browser and going to the hostname:port:
http://some-host-name.duckdns.org:8321
To persist the webserver after you log out of the shell, use nohup:
$ nohup python3 -m http.server 8321 &
