FOSS Weekly #24.14: Homelab Special Edition (and Discussing XZ Backdoor in Linux)

FOSS Weekly #24.14: Homelab Special Edition (and Discussing XZ Backdoor in Linux)

This is a special FOSS Weekly edition as it focuses on Homelab. Wondering what is a homelab? Basically, it's a dedicated computer(s) set up which resides in your home and serves various open source software on your local network. So, you run your own cloud storage, media server and a lot more.

What is a Homelab and Why Should You Have One?
Having a homelab setup has multiple advantages. Learn what it is and why you should consider a homelab for yourself.

That's the simplest of the homelab. There is no limit to what you can do with a homelab. Just browse through the r/homelab subreddit and you'll be amazed at what your peers are doing with their homelab.

In my opinion, when you have been using Linux on your personal computer for long and start wondering what should I do next, the homelab is the answer. Not only you get control over your data, you also enhance your skills. It could also help you reduce electronic waste by putting older hardware to some good use.

We are already covering tutorials on Raspberry Pi and local AI set up. You'll be seeing more educational material on homelabs regularly on It's FOSS.

Based on the feedback I received from the previous newsletter, it seems a good majority of It's FOSS readers want regular recommendation on Android FOSS apps.

💬 Let's see what else you get in this edition:

  • The XZ Utils backdoor almost causing havoc.
  • Proxmox wasting no time in saving users from VMware.
  • And other Linux news, videos and, of course, memes!
  • This edition of FOSS Weekly is supported by Netdata.

🏠💻 Homelab! Sweet Homelab!

By now, you have some idea about what a homelab is. How do you get started with setting your own?

If you can spend some money, you can get Raspberry Pi or any other single board computer. However, recently, I got an excellent 'plug and play' Homelab device in the form of ZimaBoard.

If you don't have the budget, you can use older computers and servers for this purpose. If you have one lying around in your house, good. Otherwise, you may try getting a used one from eBay like websites in your country.

Once you have got the hardware, it's time for the operating system. Now, you may install lightweight Linux distributions or simply go with server distros. But I think it will be easier if you try an operating system specially crafted for Homelab. Here are my recommendations:

If you are a bit experienced, you can have a rather advanced homelab setup using virtualization tools like Proxmox. My colleague Helder prefers this method. Here's a good learning resource on Proxmox, if you are interested.

Getting Started With Proxmox
A tutorial searies that covers everything from installing and upgrading Proxmox to using it for creating and managing VMs.

When you are running too many services in your homelab, it may become difficult to manage them. This is where dashboard software come into the picture.

You have enough information now to plan your own homelab (if you want it). Happy homelabbing 😄


📰 Linux news


🧠 What we’re thinking about

Talk of this week/month/year/decade is the very sophisticated supply chain attack to install a backdoor in XZ utility to compromise Linux servers running SSH.

How? The attacker gained trust by contributing to the project and became one of the main developers. He pushed some hidden malicious code which gets activated only in certain cases and impacts the SSH connections. And thus compromising the integrity of a Linux server.

The thing is that since it was all open source and hence it got detected by a Microsoft Engineer who noticed a 0.5 second delay with SSH.

Intriguing, isn't it? Imagine if XZ Utils was a proprietary tool. This would have probably never been discovered.

🧑‍🤝‍🧑 FOSSverse corner

Many FOSSers, including me, have been discussing the extent of the xz backdoor. You are encouraged to give your opinions too!

Xz utility had backdoor
Some of you might have come across the current hot topic in Linux world right now. The compression utility xz was backdoored in the recent versions and that too by one of its developers. He even tried pushing for the backdoored version to be included in the upcoming Ubuntu 24.04 and Fedora 41.
