FreeBSD – Linux and FreeBSD Firewalls – Part 2
In the first article of this series, we covered the major differences between two types of firewalls platforms – either Linux or FreeBSD based and what the options are. In the second part, we go a bit deeper and discuss how egress filtering is done, and how tables and sets are built. Read more about it in our second write-up.
FreeBSD – Linux and FreeBSD Firewalls – Part 1
When it comes to choosing a firewall technology for your operating system, the options can be overwhelming. This is particularly true for Linux and FreeBSD, which offer multiple choices. In this article, we’ll take a closer look at four of the most popular firewall options for both systems: iptables, nftables, ipfw, and pf, to help you make an informed decision.
FreeBSD or Linux – A Choice Without OS Wars
Uncover the key differences between FreeBSD and Linux as we break down their features and use cases, helping users make well-informed decisions based on their specific requirements.
Accelerating Datacenter Energy Efficiency by Leveraging FreeBSD as Your Server OS
Explore how FreeBSD aids datacenter energy goals, promoting efficiency in design & operation, while supporting industry & government initiatives.
FreeBSD History – Understanding the Origins of DTrace
DTraceis a powerful tool for system administrators to diagnosis system issues without unduly impacting performance. DTrace became part of FreeBSD with the release of FreeBSD 7.1 in 2009—two years before Oracle began porting DTrace, and nine years before Oracle eventually solved the inherent CDDL vs GPL license conflict.
FreeBSD vs. Linux – Tracing and Troubleshooting
When troubleshooting a Linux or FreeBSD system, you need to be able to probe the system to find answers as to why it is behaving in a particular way. In this article, we’ll provide an overview of some of the basic tools and introduce the FreeBSD equivalents of common Linux tracing and troubleshooting tools.
Sysadmin Series – How to Catch a Bitcoin Miner
What first looked like some CPU oddity in a monitoring graph became a full-fledged hunt for a bitcoin miner. Figuring out what happened and how they were operating is part of the investigation. Collecting evidence to make a case soon became akin to a detective story.
Automation and Hacking Your FreeBSD CLI
The more we automate, the more we can save time and boost our productivity to higher levels. In this article we plan on looking at how to build more human-readable outputs in FreeBSD by leveraging tools like libxo to drive better output for automation APIs.
OpenZFS – Data Security vs. Integrity
Data security is about preventing data from being disclosed, ensuring that only the correct people can access it. Data integrity ensures the data is correct, that it has not become corrupt due to hardware failure or other issues. With ZFS, you can get both.
FreeBSD vs. Linux – 5 Factors When Considering FreeBSD vs Linux – Package Management
The popularity of package managers permeates all Unix distributions. Yet there are subtle differences in the approach that Linux vs. FreeBSD take in handling packages. How does Linux compare to FreeBSD’s way of managing packages? We have identified key points to consider in the software lifecycle management of both in the article below.
