Working on this question and have no idea where to start.

The directions say that we are supposed to examine the source code and sample method located at this website:

https://firstmonday.org/ojs/index.php/fm/article/view/528/449

Next we are to read this information located on this website:

https://www.securitynik.com/2014/04/covert-channels-communicating-over-tcp.html

Questions:

How does this code work?

How could you recreate the sample?

Can you expand on the project?

What are the most important concepts from this code?

Please include URLs with your response so I can learn.

Our teacher does not approve of us using Wikipedia - please do not reference this website.

Thank you for your time.
