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.

Building a network scanner with Python

Python tools provide many native modules and support for working with sockets and TCP/IP in general. Additionally, Python can use the existing third-party commands available on the system to initiate the required scan and return the result. This can be done using the subprocess module that we discussed before, in Chapter 9, Using the Subprocess Module. A simple example is using Nmap to scan a subnet, as in the following code:

import subprocess
from netaddr import IPNetwork
network = ""
p = subprocess.Popen(["sudo", "nmap", "-sP", network], stdout=subprocess.PIPE)

for line in p.stdout:

In this example, we can see the following:

  • At the beginning, we imported the subprocess module to be used in our script.
  • Then, we defined the network that we want to scan with the network parameter...
