You can follow the story as a step-by-step tutorial, while running every serverN.py examples at the same time they say they run them and then use telnet and/or netcat like they say they use it in the story. If you really want to understand this it'll be easy enough, connect to irc.libera.chat, join say ##linux or even better #networking and ask any question that comes to mind. I'd advise anyone to do it; this little story is one of a kind.
