This is a tiny TCP stack implemented in pure Ruby, for fun and learning, inspired by @jvns.
Julia wrote a blog called: What happens if you write a TCP stack in Python?, and I saved it to my Pocket and then moved it to Chrome bookmark folder called "Call me maybe", but never touched it ever since.
Recently, I decided to give it a try and implement a tiny tcp stack in Ruby language.
There is an example in
examples/get_page.rb, you could open it and update the
FAKE_IP_ADDRESS and the webpage you would like to get. Then, just run it in your terminal:
bundle install sudo ruby examples/get_page.rb
I run it with Ruby 2.2.2 on Linux. There is an issue of
PacketFu gem to get it working on Mac OS X.
I wrote a blog about some details of this fun project, go check it out Write a TCP Stack in Ruby.
