Creating additional virtual hard disk (VHDX) for WSL2 with ext4 filesystem

Lines starting with # mean the commands have to be executed by root user under Linux shell (WSL distro). All other commands have to be executed under Windows-PowerShell as Administrator.

Make VHDX disk file and mount it under Windows

New-VHD support.vhdx -SizeBytes 25GB -Dynamic -BlockSizeBytes 1MB
Write-Output "\\.\PhysicalDrive$((Mount-VHD -Path support.vhdx -PassThru | Get-Disk).Number)"

How to setup a development environment where Git from WSL integrates with native Windows applications, using the Windows home folder as the WSL home and using Git from WSL for all tools.

Note if using Git for Windows, or any tool on the Windows side that does not use Git from WSL then there will likely be problems with file permissions if using those files from inside WSL.

Tools

These are the tools I use:

git (wsl) - Command line git from within WSL.
Fork (windows) - Git GUI (must be used with wslgit)
wslgit - Makes git from WSL available for Windows applications. Important! Follow the installation instructions and do (at least) the first optional step and then the Usage in Fork instructions.

Router logging to MQTT

This configuration sends all (or part of) your OpenWRT logs to a MQTT broker. I'm writing it up here for future reference.

I made this so I can keep track of wireless clients as they associate and disassociate with my home network. This way, my home automation setup can make decisions based on that information. :)

Installation

Setting up Qemu with a tap interface

There are two parts to networking within QEMU:

The virtual network device that is provided to the guest (e.g. a PCI network card).
The network backend that interacts with the emulated NIC (e.g. puts packets onto the host's network).

Example: User mode network

pass tools browserpass and qtpass using windows wsl wrappers

Inside wsl Alpine v3.12

sudo apk update
sudo apk add browserpass pass nano
cd ~/

Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096
