Really Simple Echo Server

As the title says, this code implements a really simple TCP echo server running on ports 3000 for sending and
3001 for listen. Written in Node.js in about 10 minutes

• To Run
  node echoserver.js

• Add your IP Address to the allow list
  echo “127.0.0.1” >> iplist

• To Test
  Open 2 terminal windows, use nc to connect to the ports:
  nc localhost 3000
  nc localhost 3001

What you type in window 1 wil be written out on terminal 2

Enjoy everyone :)
