netcat is a tool for reading and writing data over network connections using the TCP and UDP protocols. Its mission is to become a reliable tool for other applications and scripts that need to connect to the network. In this way the user can know in detail the traffic that enters his machine as well as the traffic that leaves it.

The application also acts as a debugging and scanning tool and the basic operation of this software is basically developed in three steps:

  1. Step 1: creation of a socket to connect to a server or to act as a server.
  2. Step 2: sending everything that enters through the socket.
  3. Step 3: take out through the standard output everything that is received by the socket.
