Your Comprehensive Guide to rc(8): FreeBSD Services and Automation

rc(8) Operating System

The FreeBSD rc(8) subsystem is a sensible & elastic services management framework which enables extension automation as well as customizable start/stop scripts for your services. It’s also deterministic – which means services always start in the same order every boot, a critically important feature in service critical environments. Take a deep dive into FreeBSD services and automation with this new article!

A Quick Look at the History of Package Management on FreeBSD

Pkgng became FreeBSD’s official package manager in FreeBSD 10 in 2014. Applications can be easily installed from either pkg—a system managing precompiled binary packages—or the ports tree, which automates building and installation of packages directly from their source code.

Deploying FreeBSD on Oracle Cloud

IoS Operating Systems

FreeBSD is the OS of choice for leveraging the most out of your Oracle Cloud deployment. Take advantage of the raw processing power the Ampere Altra has to offer and take the next step in evolving your infrastructure

From 0 to Bhyve on FreeBSD 13.1

FreeBSD has its own high-performance hypervisor called “bhyve”. Much like the Linux kernel’s KVM hypervisor, bhyve enables the creation and maintenance of virtual machines—aka “guests”—which run at near-native speed alongside the host operating system. Although bhyve got a later start than Linux KVM, in most ways it has caught up with its primary rival—and in some ways surpassed it.

Using Netgraph for FreeBSD’s Bhyve Networking

networking virtualization

FreeBSD 13 adds new support for a netgraph backend for virtual network devices under bhyve. Netgraph is a modular networking framework that allows for arbitrary stacking of protocols and transports, along with filtering, tunneling, redirection, inspection, injection and more—fast and feature-rich, netgraph is to networking what the geom layer is to disks and storage. This article provides a basic recipe to demonstrate some common netgraph syntax and use-cases.Why might you want to run CURRENT? If you have a large modified code base, or are building a product based on FreeBSD, CURRENT gives you a look into the future of FreeBSD. Running CURRENT will help you understand changes that are happening in the FreeBSD Operating System and it gives you an opportunity to see how your stack performs with new features.
In this article we will show how to build a CURRENT system with the debugging features disabled, and perform some benchmarks to test the impact debugging features have on performance.

Evaluating FreeBSD CURRENT for Production Use

The FreeBSD Operating System introduces new features in CURRENT, its main development branch. Snapshots of CURRENT are made available as installer images weekly.
Why might you want to run CURRENT? If you have a large modified code base, or are building a product based on FreeBSD, CURRENT gives you a look into the future of FreeBSD. Running CURRENT will help you understand changes that are happening in the FreeBSD Operating System and it gives you an opportunity to see how your stack performs with new features.

Part 2: Tuning Your FreeBSD Configuration for Your NAS

FreeBSD and OpenZFS

Building your own NAS isn’t just about having the right storage configuration. It starts with the right hardware, the right OS setup, and finally going through the right choice for your storage – OpenZFS. In this edition of our 4-part article series on how to build your own NAS we discuss about fine tuning your FreeBSD OS for excellent NAS performance.

Interacting with FreeBSD – Learning the Fundamentals of the FreeBSD Shell

The time of the CLI might seem over given the plethora of UIs these days, however, any experienced sysadmin knows just how necessary a powerful CLI like the FreeBSD shell can be. In FreeBSD 14, the default root shell is changing, and in this article we talk about the background and motivations for this change and what implications and advantages this change brings.

Controlling Resource Limits with rctl in FreeBSD

As an administrator, you may often need to limit the amount of system resources an individual uses. FreeBSD provides several methods to do just that. The rctl command can be used to provide an effective method for controlling resource limits or it can be used to set resource constraints on processes and jails. Find out how to configure and enforce your limits.

The FreeBSD Boot Process

Let’s talk about the FreeBSD boot process. It is very robust and complex, as it is well-thought. Find out what are the differences when you boot from UEFI or legacy BIOS, or from GPT and MBR partitioning schemes. Learn what happens when you use ZFS or UFS filesystem.
