#163: WSL 2 Networking
How do you access WSL 2 Virtual Machines remotely? I'll show you how WSL2 networking works and I'll also show you how to configure the proxy service on your Windows 10 computer to allow connections to your WSL virtual machines. I'll also explain the configuration of the Windows Firewall.
WSL 2 changes the way networking is configured compared to WSL 1. You need to enable proxy of traffic and you need to permit the traffic through the Windows firewall.

#159: Docker Websites On Windows 10 Nice! (WSL 2)
Want to learn how to leverage Docker containers on WSL 2 running on Windows 10? In this video I show you how to get multiple Docker containers running on WSL 2 and interact with them. It's amazing how easy it is to get multiple websites up and running on Docker using WSL 2 on Windows 10.
WSL2 is part of Windows 10, version 2004 which was released in May 2020. Rather than using a translation or compatibility layer between Linux and Windows which was used in WSL 1, WSL 2 uses virtual machine technology to allow you to run a real Linux kernel directly on Windows 10. This also allows you to run Docker within Ubuntu running on Windows 10.

Learn how to get Kali Linux installed and running on WSL 2 on a Windows 10 computer. I'll also show you how to install applications like nmap and get a GUI working with Kali Linux. By default, when you install Kali Linux with WSL 2, you won't have a GUI, but in this video I'll show you how to get that installed and configured. Go from zero to hero with Kali Linux on WSL 2.

#157: Retro 10base5 Thicknet And 10base2 Thinnet Network
This is a working example of the stuff that you read about in books. The retro network from the 1970s and 1980s. See how these networks actually worked with this fully working demonstration of 10base5, 10base2 and 10baseT. I am accessing the Internet from Windows 3.11 and Windows 98 computers connected via transceivers to a 10base5 network. These cables are also known as thicknet and thinnet. Bob Metcalfe invented Ethernet in the 1970s and it has changed the world.
This is the birth of ethernet - 10base5. Then came 10base2 and then 10base t. You should know a bit of the history of networking if you are studying for your CompTIA network+ or Cisco CCNA certifications. You may even be a CCNP and have not seen these ethernet networks in your lifetime. Learn about transceivers, vampire taps and the other old technologies used in past Ethernet networks.
This is a classic example of retro computing using a true retro network from years ago. This is before the days of lan parties when retro gaming was big using retro games such as doom.
See how the original Ethernet actually worked with Terminators, Vampire Taps, Network Interface Cards (NICs) drop cables, Attachment Unit Interfaces (AUI), Medium Attachment Units (MAU), transceivers, BNC connectors, Thicknet 10base5 cabling, 10base2 cabling and more!
Robert Bob Metcalfe developed Ethernet in the 1970s. This is a working version of that 10base5 network.

#156: Windows Terminal Finally!
Microsoft have released a free, tabbed terminal application that allows you to use PowerShell, Command Prompt, Linux, SSH and much more! This is a great application and I think it replaces all those old or expensive options on the market! No need to use Putty anymore for SSH or Telnet. No need to pay huge amounts of money for other applications unless you really need specific functionality. Fantastic to now see an OpenSource Terminal application released in 2020.
It's so easy now to have a tabbed application that supports Powershell, Command Prompt, Azure, WSL 2, SSH, Telnet and other applications.
Windows Terminal supports a lot of customization - you can change fonts, colors, background images and a whole bunch of other options.
wsl2 is a fantastic Microsoft Windows 10 development: You can run Linux directly on Windows using the windows subsystem for linux. In this video I demonstrate ubuntu 20.04 and 18.04 using wsl2.
