From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Calling all Linux enthusiasts! Help us create a comprehensive guide to Linux firewalls and security! (lemmy.dbzer0.com)

Hello fellow Linux enthusiasts!

As many of you know, Linux can be a powerful and flexible operating system, but it can also be daunting for new users, especially when it comes to securing their systems. With the abundance of information available online, it's easy to get overwhelmed and confused about the best practices for firewall configuration and basic security.

That's why I reaching out to the Linux community for help. I am looking users who are willing to share their expertise and write a comprehensive guide to Linux firewall and security.

The goal of this guide is to provide a centralized resource that covers the following topics:

Introduction to Linux firewalls (e.g., firewalld, ufw, etc.)
Understanding basic security principles (e.g., ports, protocols, network traffic)
Configuring firewalls for various scenarios (e.g., home networks, servers, VPNs)
Best practices for securing Linux systems (e.g., password management, package updates, file permissions)
Troubleshooting common issues and errors
Advanced topics (e.g., network segmentation, SELinux, AppArmor)

I am looking for a well-structured and easy-to-follow guide that will help new users understand the fundamentals of Linux firewall and security, while also providing advanced users with a comprehensive resource for reference.

If you're interested in contributing to this project, please reply to this post with your experience and expertise in Linux firewall and security. We'll be happy to discuss the details and work together to create a high-quality guide that benefits the Linux community.

Thank you for your time and consideration, and im looking forward to hearing from you!

Arch on a server, that's gonna be fun lol

There aren't many distro with a base system as tiny as Arch. It's not a bad choice at all. It's on my server since many years, working perfectly reliable. Everything except the base system is inside Podman containers. Why not?

Not necessarily saying it's a bad idea, especially with everything running within podman it's probably even quite awesome. It just feels like it's a lot more tedious to fix in the case that something got messed up. Still, not a bad idea generally, as long as you know what you're doing ^^

After using many different distros, I feel everywhere a little incompetent when trying to fix simple issues.

Arch Linux for some reason always makes things easy and easy fixable in case things go bad.
