Ok dynamic DNS for local IPv6 is gonna get tossed on for now

Not quite done with IPv6 yet. Things to look at next include:

* Assign IPv6 to Kubernetes cluster pods/services
* BGP v6
* Configure external-dns to create AAAA records
* Map traffic inbound to the services without anti-patterns

(This will not be finished before I start work on the storage section of the mini rack)

URLs should be able to include HTTP verbs and headers.

They say "URLs define the "what" not the "how"" but protocol prefixes, file extensions, and query parameters are part of the how and yet they all exist in the URL.

Leaving HTTP verbs and headers out of URLs was an arbitrary decision.

📢 OWASP Ottawa June 2025 Meetup 📢

Join us in person at the University of Ottawa for our next OWASP Ottawa meetup on June 18, 2025, as we explore the human side of cybersecurity.

⏰ Time: 6:00 PM EST – Arrival, setup & pizza 🍕
6:30 PM EST – Technical Talks
📍 Location: 150 Louis-Pasteur Private, University of Ottawa, Room 117
🎙️ Talk: “Hacking the Human Firewall: Insights from Social Engineering Corporations”
👥 Speakers: Kyle Falcon, PhD, Ahmed Shah, Mathieu Quirion, and Kevin Tremblay – Security & GRC Analysts at Malleum

Despite all the advanced tech, humans remain the weakest link in cybersecurity. This talk will dive into real-world social engineering campaigns and will discuss:

When was the last time you have played with KDE Connect?

You've never heard of that? Let me enlighten you. KDE Connect is a suite of very handy Network tools, to get the maximum out of the transfer and the control of data & programs between your KDE computer and your Androids.

It is in fact so versatile that even if your KDE computers are not connected, you can still do a lot of things between your Androids which are running the network software suite.

There are so many things you can do you should just download it yourself and put it on your Androids

A few highlights are transferring files between your devices in a transparent manner where no company like Google can snoop anything

Controlling media players from 1 device through all the others.

Getting notifications between different devices and even getting output, graphical output from different devices on others.

Controlling your Android with a mouse from a KDE Connect computer

The list goes on

Note:
If you're running a Linux distro with a running firewall, you have to make sure that your firewall has all the ports open for KDE connect. There are examples of the ports needed, in the docs.
I also have them {for {g}ufw}

@mrencyclopedia meanwhile professional gear (i.e. #networking) comes in 3 flavours:

1. "You won't notice me in your fancy office! Feel free to paint over me if you do so anyway..."

2. "This is PRO GEAR SPEC! Where are the Rack Nuts? Also gimme redundant power please..."

3. "I'm RUGGED af! Shove me into your filthy edge cabinet, hook me up to your janky power, old custom industrial equipment and don't worry about fans, cuz I got none... Muhahaha!"

Ok not bad, I think I've got dnsmasq working how I want, I'll migrate it tomorrow

Previously I felt stuck with bind as the primary be cause I wanted to configure records via external-dns, terraform, and DHCP. Dnsmasq can only do it via DHCP.

The new structure has dnsmasq performing DNS/DHCP, but forwarding requests to the cluster's DNS server. I have cut down the number of static DNS records so I'm just skipping terraform, I'll manage the single config file via git.

I haven't started working out how to do ipv6 DHCP/DNS just yet, but I see some useful options in dnsmasq

Can anyone explain to me why I get my full gigabit Ethernet speeds (900 down/up) when I have WiFi turned off, but if I have wired Ethernet with WiFi turned on, it drops to 200/250?
