/// 12 May 2021, 11:00 am ////// Linux For Everyone///
Welcome back to the conclusion of my interview with System 76 Principal Engineer Jeremy Soller! In our 2nd hour, we cover everything from VR gaming to in-house laptops to the importance of firmware.
There's also a rather passionate rant about Audacity's now-infamous Pull Request #835.
Plus, a new Discovery of the Week, and a new rabbit hole: servers!

Doc Searls and Jonathan Bennett talk with Steven J. Vaughan-Nichols about what’s happening in technology journalism, with the open source world he knows perhaps better than any other journalist on the case, and with where he got started: in space and space technologies. (Bonus fact: Steven digs Starlink, and Jonathan is using it to participate in the show.)

- Open Letter: DistroWatch and Nitrux — For the better part of three years, we have remained silent about your ongoing efforts to affect people’s perception of our Linux distribution continuously. We have tried our best not to engage with your evident hostility and disregard to inform your viewers and visitors about correct facts of the Linux distributions you display on your website, especially ours. However, we have decided to take a stance. It is today, the 6th of May, that we gallantly demand you to stop.
- Uri’s Blog: Unpopular Opinion Penguin #3: The Empire Strikes Back — I’m here to take a look at the newest “review” that our lovely haters (let’s call them for what they are) at DistroWatch published on their website some weeks ago.
- DistroWatch.com: Nitrux
- Nitrux — Nitrux is a Linux desktop distribution directly based on Debian. It uses the Calamares installer and includes NX Desktop and NX Firewall on top of the KDE Plasma 5 desktop environment and MauiKit Applications.
- Meet Nitrux: The Most Beautiful Linux Distribution Ever?
- Nitrux on Twitter
- MauiKit — A free and modular front-end framework for developing fast and compelling user experiences.
- Kirigami UI Framework — Build beautiful, convergent apps that run on phones, TVs and everything in between.
- Changelog: Nitrux 1.4.0
- NX Desktop — NX Desktop is a customization layer for Plasma 5.
- AppImageHub — Here are 1200 apps (and counting) that you can run on Linux without installation.
- Installing other DEs in Nitrux — During last month’s release of Nitrux, we made available a minimal ISO to let users install Nitrux and also install a different desktop environment and a selection of applications than the ones we include by default.
- NX Software Center — A GUI to install and manage AppImages.
- Nitrux: pnx — pnx (lowercase; originally Pacman for Nitrux) allows users to install software from Linux distributions that use the Pacman package manager on other Linux distributions that don’t use it without interfering with the distributions default package manager.
- What’s Nitrux? The future. – with Uri Herrera
- Linux Spotlight – Uri Herrera of NitruxOS
- Feedback: PrivateBin — A minimalist, open-source online pastebin where the server has zero knowledge of pasted data. Data is encrypted/decrypted in the browser using 256 bits AES.
- PrivateBin Docker Setup
- Feedback: PIE Bin — Pre-Internet Encryption for Text.
- Feedback: CryptPad — CryptPad is the Zero-Knowledge real-time collaborative editor.
- CryptPad Installation Guide — This guide is about installing a public CryptPad instance available on the internet.
- Pick: TLP — Optimize Linux Laptop Battery Life.
- Pick: TLPUI — A GTK user interface for TLP written in Python.
- Fedora — TLP 1.3.1 documentation
In this episode Steve joins us again to discuss networking. Building on the knowledge from our last episode we dig further into ipv6 and other network technology!
— During The Show —
01:00 – VLAN question – Scott
- Management VLan is for admin not printers etc
- Set the switch to only allow access on the management VLan
- Use firewall rules to allow or deny cross VLan access
08:10 – Replace Unify with TP Link Omada? – Charlie
- Checking it out, will get back to you
09:00 – Just FYI problem accessing Wireguard tutorial – Paul
09:30 – What Router Should I buy? – Nik
12:15 IPv4
- Broadcast traffic – sends a packet to everyone, not forwarded by routers
- Broadcast Domain – Any computer that can hear a broadcast packet
- ARP Table – Table that matches switch port to mac address
- Computers also keep ARP Tables – Including Host Name, MAC Address, IP Address
- Rebooting a switch will cause it to rebuild the ARP Table
- Private IP Addresses – IPv4 Addresses set aside for internal networks
- RFC 1918
- NAT – Network Address Translation – Public IP <-> Private IP
- [IP Chicken](ipchicken.com)
- Router typically hands out DNS Server+IP Address+Hostname
30:00 IPv6
- IPv6 packet types
- Anycast
- Multicast
- Link-Local
- IPv6 Anycast – Send out a packet to an IP address, expecting multiple devices to have the same IP Address but only the closest responds
- IPv6 Multicast – Tries to only hit intended IP addresses
- Link-Local – Automatically assigned, non route-able, Required for IPv6
- Unique-Local – Private or Public route-able IP address
- Host bit of IPv6 identifies your device across networks
41:50 Reading IPv6
- First hextet = IANA Assigned prefix
- Second hextet = Your Geographical region
- Third hextet = Your ISP
-
Fourth hextet = Your Network
-
Leading zeros can be omitted
This IP:
FE80:0ED1:0098:000A:0000:0000:0AED
Can be expressed like this:
FE80:ED1:98:A::AED
-
IPv6 Loopback address
::0
48:00 Getting an address
- Computer sends an icmpv6 packet called a Router Solicitation
- The router responds with its information (with its Link Local address)
- Either the router generates an ipv6 based on the requesting computers MAC address OR the computer chooses its own IP address
- The computer sends a Neighbor Solicitation packet which is basically the computer attempting to ping a device on the network with its IP address to see if its chosen IP already exists
-
IPv6 you are on the internet by default unlike IPv4 in most setups
-
"Host" bits are based on your MAC address, which can be used for finger printing/tracking
Addressing
Address broken into hextets
