Mastering Python Networking - Third Edition

By: Eric Chou

Overview of this book

Networks in your infrastructure set the foundation for how your application can be deployed, maintained, and serviced. Python is the ideal language for network engineers to explore tools that were previously available to systems engineers and application developers. In Mastering Python Networking, Third edition, you’ll embark on a Python-based journey to transition from traditional network engineers to network developers ready for the next-generation of networks. This new edition is completely revised and updated to work with Python 3. In addition to new chapters on network data analysis with ELK stack (Elasticsearch, Logstash, Kibana, and Beats) and Azure Cloud Networking, it includes updates on using newer libraries such as pyATS and Nornir, as well as Ansible 2.8. Each chapter is updated with the latest libraries with working examples to ensure compatibility and understanding of the concepts. Starting with a basic overview of Python, the book teaches you how it can interact with both legacy and API-enabled network devices. You will learn to leverage high-level Python packages and frameworks to perform network automation tasks, monitoring, management, and enhanced network security followed by Azure and AWS Cloud networking. Finally, you will use Jenkins for continuous integration as well as testing tools to verify your network.

The lab setup

The devices being used in this chapter are a bit different from the previous chapters. In the previous chapters, we were isolating a particular device to focus on the topic at hand. For this chapter, we will use a few more devices in our lab to illustrate the function of the tools we will be using. The connectivity and operating system information are important as they have ramifications regarding the security tools that we will show later in this chapter. For example, if we want to apply an access list to protect the server, we need to know what the topology looks like and which direction the client is making their connections from. The Ubuntu host connections are a bit different than what we have seen so far, so please refer to this lab section when you see the example later if needed.

We will be using the same Cisco VIRL tool with four nodes: two hosts and two network devices. If you need a refresher on Cisco VIRL, feel free to go back to Chapter 2, Low-Level Network...
