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.
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.
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.
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.
The inetd ‘super-server’ is a special application that ties incoming network connections to locally-run commands. While it is not a common part of deployments today, it still has potential to be useful in production environments, and definitely has a place in the future of FreeBSD.
FreeBSD can report on the health of the system and perform various routine maintenance tasks using its own built-in mechanism for periodically running scripts. Learn about the periodic system and how to find available scripts, write your own scripts and where and how to apply them.
Pot and Nomad are two tools intended to provide cluster provisioning on FreeBSD and replace tools like Docker and Kubernetes, which suffer from lack of sufficient support on FreeBSD. Read how in this article.
Let’s talk Dummynet! A traffic manager, bandwidth manager and link emulator, Dummynet is a powerful part of FreeBSD. Dummynet gives us the tools to control how traffic at bottlenecks is treated and can be used to make reservations on our hosts so they remain reachable when under high packet load.
Keeping systems secure and free of any vulnerabilities is an important task in any sysadmin’s or developer’s book. Fortunately, FreeBSD systems come with several tools to accomplish that task for both its Base System and installed 3rd party packages.
In this article, we will take a look at how these tools can help us efficiently manage security vulnerabilities in our FreeBSD systems
A lot of great papers have been written throughout the history of FreeBSD. For most of the features you see today in a modern FreeBSD Operating System there is a corresponding paper that was written during its development or after its inclusion to document its addition.
Today, we’re looking at two of our favourite papers, trying to highlight their contribution to the FreeBSD Operating System.
