Mastering Python Networking - Second 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 this second edition of Mastering Python Networking, 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 book begins by reviewing the basics of Python and teaches you how Python can interact with both legacy and API-enabled network devices. As you make your way through the chapters, you will then learn to leverage high-level Python packages and frameworks to perform network engineering tasks for automation, monitoring, management, and enhanced security. In the concluding chapters, you will use Jenkins for continuous network integration as well as testing tools to verify your network. By the end of this book, you will be able to perform all networking tasks with ease using Python.

A more declarative framework

You woke up one morning in a cold sweat from a nightmare you had about a potential network security breach. You realized that your network contains valuable digital assets that should be protected. You have been doing your job as a network administrator, so it is pretty secure, but you want to put more security measures around your network devices just to be sure.

To start with, you break the objective down into two actionable items:

  • Upgrading the devices to the latest version of the software, which requires:
    1. Uploading the image to the device.
    2. Instructing the device to boot from the new image.
    3. Proceeding to reboot the device.
    4. Verifying that the device is running with the new software image.
  • Configuring the appropriate access control list on the networking devices, which includes the following:
    1. Constructing the access list on the device.
    2. Configuring...
