A Short IPv6 Guide for Home IPv4 Admins

This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.

Let’s begin.

First of all, there are some concepts that one must unlearn from ipv4:

Concept 1

FAQ on the xz-utils backdoor (CVE-2024-3094)

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.

Summary

One's thousand day(s) celebration occurs every thousand days of a person's life. They are meant to be a recognition of getting this far, and are celebrated at the person's own discretion.

uConsole Notes

Batteries

I use two XTAR 16850-3500 cells and I get about 8h of active usage out of them.

Get GNOME Shell and GDM3

sudo apt install gnome-shell gdm3

There's some weird stuff in some server responses to /api/v1/instance and /api/v2/instance.

Here's some I've seen in the wild. Format is:

Heading with server type (e.g., "akkoma") and whether this was v1 or v2
Then the error when trying to parse the data
Then a list of all the servers that triggered the same parse error, with their reported version number

Some of these have been fixed in newer versions of the servers but the fixes haven't fully rolled out.
