TCP Ping

In this session we will attempt to build a server that can send and receive messages over TCP.

We will have to learn how to use Erlang modules from Elixir; get familiar with the Erlang documentation; learn about the :gen_tcp module.

Task

• Create a server using :gen_tcp.listen (active: false, and in binary mode) that accept a connection using :gen_tcp.accept and echo messages send to it. Connect to it using :gen_tcp.connect and send messages using :gen_tcp.send.

• Create a TCP server wrapped in a GenServer that listen to messages using active: true

• Create a ping server that reply with pong
