• Managing a fleet of NixOS Part 2 - A KISS design

  Let's continue my series trying to design a NixOS fleet management.

• Local peer to peer binary cache with NixOS and Peerix

  There is a cool project related to NixOS, called Peerix. It's a local daemon exposed as a local substituter (a server providing binary packages) that will discover other Peerix daemon on the local network, and use them as a source of binary packages.

  Peerix is a simple way to reuse package already installed somewhere on the network instead of downloading it again. Packages delivered by Peerix substituters are signed with a private key, so you need to import each computer public key before being able to download/use their packages. While this can be cumbersome, this also mandatory to prevent someone on the network to spoof packages.

  Perrix should be used wisely, because secrets in your store could be leaked to others.

• nsupdate - update failed: REFUSED - Dan Langille’s Other Diary

  A while back, the https://www.freebsddiary.org/topics.php#opteron – the colo facility was purchased and the new owners are not interested in donating services to open source projects.

  That host also acted as a DNS host for all my domain. I pressed a small VPS into service. It handled the query services fine, but updates were sluggish. It took a few hours for it to catch up to Let’s Encrypt renewals.

  To be fair, this $5 box does a decent job as an external monitoring host.

  Over the weekend, I configured another host as a name server.

  Monitoring proved it never lagged with updates.

• Getting Home Assistant running in a FreeBSD 13.1 jail - Dan Langille’s Other Diary

  Home Assistant is not friendly for plain installs. It seems designed for containers or running everything out of pip install. That, in itself, is a disturbing trend I’ve seen on several projects (what? you’re not running a git cloned image?).

  I’ve seen reports of people running containers etc. However, I want to run this on FreeBSD. I don’t want to muck about with installing containers etc. If containers are the only way for a project to run, you’re doing it wrong.

  I tried recently and eventually succeeded after several failures. Open source should not be this difficult. The devs seem unware of the problems. A previous attempt in June involved an Ansible playbook. After terrible install this past Tuesday night, I’m going to amend that playbook.

• How To Install VeraCrypt on Linux Mint 21 - idroot

  In this tutorial, we will show you how to install VeraCrypt on Linux Mint 21. For those of you who didn’t know, VeraCrypt is free open-source disk encryption software for Windows, macOS, and Linux. The software can create a virtual encrypted disk that works just like a regular disk but within a file. It can also encrypt a partition or the entire storage device with pre-boot authentication.

  This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of a VeraCrypt encryption tool on Linux Mint 21 (Vanessa).
