What you need for this book

This book assumes a good level of experience with Linux operating systems and an intermediate knowledge of the Bash shell, and since there will be some chapters dealing with Nagios monitoring and Slack messaging, basic understanding of networking concepts is required.

A simple Linux installation is required with really low specifications, as even the Nagios plugin can be tested without requiring the actual installation of the monitoring system. So, this is the minimum configuration required:

CPU: single-core
Memory: 2 GB
Disk space: 20 GB

For this book, you will need the following software:

Linux operating system: Debian 8
Nagios Core 3.5.1
OpenSSH 6.7p1
rssh 2.3.4

Internet connectivity is required to install the necessary service packages and to try out some of the examples.

Zarrelli

Giorgio Zarrelli is a passionate GNU/Linux system administrator and Debian user, but has worked over the years with Windows, Mac, and OpenBSD, writing scripts, programming, installing and configuring services--whatever is required from an IT guy. He started tinkering seriously with servers back in his university days, when he took part in the Computational Philosophy Laboratory and was introduced to the Prolog language. As a young guy, he had fun being paid for playing games and write about them in video game magazines. Then he grew up and worked as an IT journalist and Nagios architect, and recently moved over to the threat intelligence field, where a lot of interesting stuff is happening nowadays. Over the years, he has worked for start-ups and well-established companies, among them In3 incubator and Onebip as a database and systems administrator, IBM as QRadar support, and Anomali as CSO, trying to find the best ways to help companies make the best out of IT. Giorgio has written several books in Italian on different topics related to IT, from Windows security to Linux system administration, covering MySQL DB administration and Bash scripting.
