For a long period of time, the CLI was the only access method available to manage and operate network devices. Operators and administrators used to have SSH and Telnet to access the network terminal for configuration and troubleshooting. Python, or any programming language, has two approaches to communicating with devices. The first one is to use SSH or telnet the same as before and get the information, then process it. This method is called screen scraping and requires libraries that will be able to establish a connection to the device and execute a command directly on the terminal, and other libraries to process the returned information to extract useful data from it. This method often requires knowledge of additional parsing languages, such as regular expressions, to match the data pattern from the output and extract useful data from it...

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.
