Hands-On Enterprise Automation with Python

By: Bassem Aly

Overview of this book

Hands-On Enterprise Automation with Python starts by covering the set up of a Python environment to perform automation tasks, as well as the modules, libraries, and tools you will be using. We’ll explore examples of network automation tasks using simple Python programs and Ansible. Next, we will walk you through automating administration tasks with Python Fabric, where you will learn to perform server configuration and administration, along with system administration tasks such as user management, database management, and process management. As you progress through this book, you’ll automate several testing services with Python scripts and perform automation tasks on virtual machines and cloud infrastructure with Python. In the concluding chapters, you will cover Python-based offensive security tools and learn how to automate your security tasks. By the end of this book, you will have mastered the skills of automating several system administration tasks with Python.

Handling IP addresses and networks with netaddr

Working and manipulating IP addresses is one of the most important tasks for network engineers. Python developers provide an amazing library that can understand the IP addresses and work on them, called netaddr. For example, assume you developed an application and part of it is to get the network and broadcast address for You can do that easily via two built-in methods inside the modules called network and broadcast respectively:

In general, netaddr provides support for the following features:

Layer 3 addresses:

  • IPv4 and IPv6 addresses, subnets, masks, prefixes
  • Iterating, slicing, sorting, summarizing, and classifying IP networks
  • Dealing with various range formats (CIDR, arbitrary ranges and globs, nmap)
  • Set-based operations (unions, intersections, and so on) over IP...
