Learning Python Networking - Second Edition

By: José Manuel Ortega, Dr. M. O. Faruque Sarker, Sam Washington

Overview of this book

Network programming has always been a demanding task. With full-featured and well-documented libraries all the way up the stack, Python makes network programming the enjoyable experience it should be. Starting with a walk through of today's major networking protocols, through this book, you'll learn how to employ Python for network programming, how to request and retrieve web resources, and how to extract data in major formats over the web. You will utilize Python for emailing using different protocols, and you'll interact with remote systems and IP and DNS networking. You will cover the connection of networking devices and configuration using Python 3.7, along with cloud-based network management tasks using Python. As the book progresses, socket programming will be covered, followed by how to design servers, and the pros and cons of multithreaded and event-driven architectures. You'll develop practical clientside applications, including web API clients, email clients, SSH, and FTP. These applications will also be implemented through existing web application frameworks.

Chapter 10, Programming with Sockets

  1. socket.accept() is used to accept the connection from the client. This method returns two values, client_socket and client_address, where client_socket is a new socket object that's used to send and receive data over the connection.
  2. socket.sendto(data, address) is used to send data to a given address.
  3. The bind(IP,PORT) method allows you to associate a host and a port with a specific socket, for example, server.bind(("localhost", 9999)).
  4. The main difference between TCP and UDP is that UDP is not connection-oriented. This means that there is no guarantee that our packets will reach their destinations, and there is no error notification if a delivery fails.
  5. socket.connect_ex(address) is used for implementing port scanning with sockets.
  6. RawCap.exe.
  7. socket.socket (socket.AF_INET6, socket.SOCK_STREAM).
  8. There is a module called selectors...
