#155: Windows Terminal And WSL 2 Tips
You can now run Docker on Windows easily with the Windows Subsystem for Linux 2 (WSL 2). Get started learning Docker and Linux! It's even supported on Windows 10 home version.
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.

#153: Building A Retro 1970s Network
Time for a real working retro network with 10base5, 10base2, Windows 3.11 and Windows 98. 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!
It's really hard to work with these old types of Ethernet - especially 10base5. In this video I use a retro computer - an Amstrad 386 laptop to ping sites on the Internet like google.com across a Thicknet and Thinnet coaxial cabling network.
It's a retro network, but it really helps you learn about why terminators where important, about CSMA/CD, cables and other Ethernet technologies. This is one of multiple videos in my Retro Networking series.

#152: WSL 2 Getting Started
The Windows Subsystem for Linux 2 (WSL 2) is here. It's now easy to get started with Linux and integrate Ubuntu 20.04 LTS quickly from within 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.

#150: CML FAQs: Wireshark, passwords, Docker and more.
How do you capture packets in CML? Is Wireshark available? Is Docker supported? What are devices passwords? How do I add interfaces to devices? These are some of the questions I answer in this video.
Cisco CML-P (VIRL 2) is here: Learn how to download, install and configure Cisco CML-P (VIRL 2) in my series of videos. The new version of Cisco VIRL allows you to create virtual Cisco networks using just your Web browser. You don't have to use a thick client or any other software - everything is included and everything is easy to use.
The new version of Cisco VIRL 2 is one of your best options for CCNA, CCNP and CCIE Labs. VIRL 2 has multiple advantages over other platforms such as GNS3 or EVE-NG. VIRL 2 supports an HTML5 web client and contains all the Cisco IOS images. You don't have to use a thick client like you do with GNS3. You don't have to follow a convoluted process to get Cisco images working like you do with EVE-NG.
You don't have to try to find images as they are all included as part of your VIRL subscription and by simply mapping an ISO drive to your virtual machine you can immediately start using all Cisco IOS images in your topologies.
VIRL2 is also an official Cisco product - that means that you don't have to worry about any legal issues with regards to running Cisco IOS images on your laptop. This is an official Cisco product that is supported by Cisco. By paying your yearly subscription fee of $199, you can use Cisco IOS images such as IOSv, IOSvL2, ASAv, NX-OSv and others without any worries. VIRL 2 has everything you need to get started.
Cisco have made massive changes to their certification programs and it is fantastic to see the new version of VIRL in action.

#146: Free CCNP 350-401 ENCOR Complete Course: 6.4: REST APIs Part 6
This is a FREE complete CCNP 350-401 ENCOR Course. In this video I show you how to use Python and a REST API to create and delete multiple interfaces on a Cisco IOS XE router using the built in REST API.
It's important that you learn both REST APIs and Python for the ENCOR exam as well as the real world.
I will be covering all the topics in the Cisco CCNP ENCOR exam in this course. I want to make this content practical and it will include a lots of labs and demonstrations to help you better understand topics on the exam.
