100% Discount || FreeBSD 13.x – Mastering JAILS

Hello,

welcome to the ‘FreeBSD 13.x – Mastering JAILS’ course. The purpose of this course is to give a deep overview of what Jails are, and how to use them for building testing or production-ready environments. All this using a great BastilleBSD project.

What you’ll learn:

• Create FreeBSD lab environment for a safe Jails testings
• Get deeper understanding what Jails are
• Maintain Jails using BastileBSD
• Understand Jails networking
• Get some practice with Jails backups
• Use BastileBSD for maintaining multiple Jails environment in seamless way

What are FreeBSD Jails from Wikipedia:

“The jail mechanism is an implementation of FreeBSD’s OS-level virtualization that allows system administrators to partition a FreeBSD-derived computer system into several independent mini-systems called jails, all sharing the same kernel, with very little overhead. It is implemented through a system called jails, as well as a userland utility plus, depending on the system, a number of other utilities. The functionality was committed into FreeBSD in 1999 by Poul-Henning Kamp after some period of production use by a hosting provider and was first released with FreeBSD 4.0, thus being supported on a number of FreeBSD descendants, including DragonFly BSD, to this day.

The need for the FreeBSD jails came from a small shared-environment hosting provider’s (R&D Associates, Inc.’s owner, Derrick T. Woolworth) desire to establish a clean, clear-cut separation between their own services and those of their customers, mainly for security and ease of administration (jail(8)). Instead of adding a new layer of fine-grained configuration options, the solution adopted by Poul-Henning Kamp was to compartmentalize the system – both its files and its resources – in such a way that only the right people are given access to the right compartments.”

Topics covered in this course:
‘Mastering Jails’ course covers most of the Jails setup options available and required for running Jails in real live scenarios. The main topics include:

• Jails Essentials
• Creating a FreeBSD Lab environment
• Using BastilleBSD for managing Jails in many different ways
• Setting Jails networking in the right way
• BONUS: Running FreeBSD Jail on Raspberry PI

During the course, we build a lab environment with fresh FreeBSD installation and we setup Jails from the ground to a production-ready environment. We will practice working with Jails, backing them up, or do networking the right way. All this using a great BastilleBSD project.

Summary:

FreeBSD 13.x Mastering Jails course covers various topics related to using Jails to manage running different software packages in a secure way. Using Jails you can avoid security issues/holes in software packages you host on your system.
