An Introduction to GraphViz
Using dot, twopi and NEATO to create graphics is not difficult. The three utilities were made according to the UNIX philosophy: they are easy to use, they do one thing well and the only requirement for using them is a simple text editor.
Graphical tools that make use of dot, twopi and NEATO languages for making graphs exist as well, but I still prefer the command line. The presented tools can be used for simple graphs as well as for complex graphs.

In modern computer systems, privacy and security are mandatory. However, connections from the outside over public networks automatically imply risks. One easily available solution to avoid eavesdroppers’ attempts is SSH. But, its wide adoption during the past 21 years has made it a target for attackers, so hardening your system properly is a must.
Additionally, in highly regulated markets, you must comply with specific operational requirements, proving that you conform to standards and even that you have included new mandatory authentication methods, such as two-factor authentication. In this ebook, I discuss SSH and how to configure and manage it to guarantee that your network is safe, your data is secure and that you comply with relevant regulations.Get the Guide
