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.

VyOS example

VyOS is a fully open source network OS that runs on a wide range of hardware, virtual machines, and cloud providers ( Because of its open source nature, it is gaining wide support in the open source community. Many of the open source projects are using VyOS as the default platform for testing. In the last section of the chapter, we will look at a quick VyOS example.

The VyOS image can be downloaded in various formats: Once downloaded and initialized, we can install the Python library on our management host:

(venv) $ pip install vymgmt

The example script,, is very simple:

#!/usr/bin/env python3
import vymgmt
vyos = vymgmt.Router('', 'vyos', password='vyos')
vyos.set("system domain-name")
