Create LXC Templates [Chuck Nemeth]
Create LXC Templates [Chuck Nemeth]
Create LXC Templates Every time inspiration struck or I saw a blog post with something I wanted to try, it was frustrating and time consuming to get the base operating system set up to the way I like it before proceeding with the project.

Mount share only if connected to Tailscale - Linux - Tailscale
Sorry for the delayed response, hope it helps. Documenting anyway as it might help others as well. The idea is to have a systemd target (tailscale-online.target) that we ensure is enabled if and only if tailscale is up and vice versa. To do that write and enable tailscale-dispatcher.timer: [Unit] Description=Checks for tailscale state and syncs with `tailscale-online.target` BindsTo=tailscaled.service After=tailscaled.service [Timer] OnBootSec=0 OnUnitInactiveSec=10 AccuracySec=1 [Install]...

Installing NixOS on a Raspberry Pi 3B | Eisfunke
I installed NixOS on a Raspberry Pi 3B. Here’s a write-up on the process, the problems I encountered and what I learned. Let me tell you: the Pi’s boot process is weird. Also it’s too slow to even evaluate my NixOS config so I had to build and deploy it remotely, and some other fun stuff.

The Power of Zero-Trust Architecture: Building a Secure Internal Network with Nebula
The Power of Zero-Trust Architecture: Building a Secure Internal Network with Nebula
Imagine if we could establish a level of trust that in our network, we can verify with certainty that a computer really is who it says it is. By bringing mutual authentication and trust into networking, we can better make security decisions on when connections should be allowed. This can enable our services to talk to each other securely over the global internet, and reduce the dependence on a a trusted perimeter.
