Notes on bootstrapping Raspberry Pi OS. This blog post is written in the heavy influence of a cold. Take care with your copy and pasting. No more information at the point.

Bootstrap Raspberry Pi Zero 2 W with Ubuntu using cloud-init. OTG configured as network card, WiFi, ssh-keys from GitHub and zram swap enabled. All examples are made to be run on a Fedora Desktop. Adjust scripts if you use another distro.

From Wikipedia: WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks (VPNs), and was designed with the goals of ease of use, high speed performance, and low attack surface.

Are you, as I, suffering from Detected Hardware Unit Hang in the kernel log from an e1000e network card? How do you notice it. A transfer goes to zero bytes for around 10 seconds, then restarts, then goes to zero, then restarts and so on…

I’ve tried to ditch Dropbox for a long time. But the need for synchronizing folders between my computers have held me back. Syncthing solves this for me. It’s decentralized syncrhonization between all my units, including my phone, without the need to go through a 3rd party server.

Excerpt from Syncthings homepage: Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it’s transmitted over the Internet.

The router firmware Tomato, see previous post RT-N66u with Tomato by Shibby firmware, can act as an OpenVPN server.

Using open Wi-Fi access points can be very useful and necessary, but it is inherently insecure. Using the router as an OpenVPN server can increase your privacy and security when you are on the go. By creating an encrypted VPN connection back home to the router, you don’t only get protection from nosy eavesdroppers but you get access to all your equipment behind the router at home as well.

This is a part of my personal notes. Use this information at your own risk. If you are uncertain or don’t know what you are doing. Do not proceed.

Asus RT-N66U is a Linux based wireless router. The stock firmware can be a bit limiting for the more advanced user. If you want better QoS, OpenVPN or just more control over the network I recommend installing Tomato by Shibby firmware.

Download the latest version of the firmware from Tomato by Shibby. Look for Asus RT-N66u 64k in the version folder in K26RT-N repository.
