Overview of this book

This Learning Path highlights major aspects of Python network programming such as writing simple networking clients, creating and deploying SDN and NFV systems, and extending your network with Mininet. You’ll also learn how to automate legacy and the latest network devices. As you progress through the chapters, you’ll use Python for DevOps and open source tools to test, secure, and analyze your network. Toward the end, you'll develop client-side applications, such as web API clients, email clients, SSH, and FTP, using socket programming. By the end of this Learning Path, you will have learned how to analyze a network's security vulnerabilities using advanced network packet capture and analysis techniques. This Learning Path includes content from the following Packt products: • Practical Network Automation by Abhishek Ratan • Mastering Python Networking by Eric Chou • Python Network Programming Cookbook, Second Edition by Pradeeban Kathiravelu, Dr. M.

Serving HTTP requests from your machine


You would like to create your own web server. Your web server should handle client requests and send a simple hello message.

How to do it...

Python ships with a very simple web server that can be launched from the command line as follows:

This will launch an HTTP web server on port 8080. You can access this web server from your browser by typing http://localhost:8080. This will show the contents of the current directory from where you run the preceding command. If there is any web server index file, for example, index.html, inside that directory, your browser will show the contents of index.html. However, if you like to have full control over your web server, you need to launch your customized HTTP server.

Listing 4.2 gives the following code for the custom HTTP web server:

#!/usr/bin/env python
