Connect Azure Cloud Shell to Virtual Network vNet

Posted in Cloud, Containers, Microsoft, Microsoft Azure, PowerShell

As you know, Azure Cloud Shell is a great management tool to manage your Azure resources. Azure Cloud Shell is an interactive, authenticated, browser-accessible shell for managing Azure resources. It provides the flexibility of choosing the shell experience that best suits the way you work, either Bash or PowerShell. You can learn more about Azure Cloud Shell here. If you wanted to manage Azure resources such as Azure virtual machines (VMs), you needed to connect to a public IP address of a virtual machine, which really didn’t work in all scenarios. With the latest update, you can now connect Azure Cloud Shell to an Azure virtual network (vNet). With the new method, you can now deploy the Azure Cloud Shell container within your virtual network (vNet), which now allows you to use PowerShell remoting, SSH, or other command-line tools such as kubctl using private IP addresses.

Requirements

Before you can use Cloud Shell in your own Azure Virtual Network, you will need to create some resources to support this functionality.

Virtual Network – The virtual network in which the resources are located you want to manage or the network that peers with a virtual network where your Azure resources are.
Subnet – In that virtual network you will need a dedicated subnet to host Cloud Shell containers.
Network profile
Azure Relay – An Azure Relay allows two endpoints that are not directly reachable to communicate.
Storage Account – The storage account needs to be accessible from the virtual network that is used by Cloud Shell.

There are also some considerations you need to be aware of, such as currently supported Azure regions during the preview, Azure Relay adds additional cost and slower startup speed of Cloud Shell containers. You can learn more about the requirements here.

Connect Azure Cloud Shell to a virtual network

To make the deployment easy, there are Azure Resource Manager templates available to deploy the necessary network and storage resources. In my step by step guide, I already have a virtual network deployed within my subscription with the resources I manage. If you don’t have that yet, and you want to try this out, you will need to create a resource group and a virtual network.

Simply the deploy the following two templates:

Deploy Azure Cloud Shell Network ARM template

You can get the Azure Container Instance OID by running the following command:

Get-AzADServicePrincipal -DisplayNameBeginsWith 'Azure Container Instance'

Also, make sure that the subnet ranges are part of the address range in your virtual network.

Reconnect Cloud Shell

If you have used Azure Cloud Shell before, you will need to reconnect that to the specific resources. You can simply run the command “cloudrive unmount” or “dismount-cloudrive”.

After that you can reconnect your Cloud Shell and select the isolated network option. Keep in mind this feature is currently in preview, and only available in West US and West Central US.

Connect Azure Cloud Shell to virtual network

This will then take a moment to deploy.

Requesting a container

After the Cloud Shell container is deployed within the virtual network, you can now start using private IP addresses within that virtual network or virtual networks that are peered.

SSH into Azure VM with Private IP address from Cloud Shell

I hope this blog gives you a short overview of how you can integrate Cloud Shell in your private Azure virtual network. If you have any questions, feel free to leave a comment.

Install Intel NUC Windows Server 2019 Network Adapter Driver

Posted in Cloud, Hardware, Hyper-V, Microsoft, Server Core, Windows Server, Windows Server 2019

As you know, I am using an Intel NUC as my Windows Server lab machine, where I run Windows Server 2019 and Hyper-V on. Many people asked me about how you can install the Intel NUC Windows Server 2019 Network Adapter driver because there are no Windows Server 2019 drivers for it. My blog reader, Michael Williams, shared how you can install the Windows Server 2019 Network adapter drivers on the Intel NUC 8th generation.

Here are the simple steps you can follow to install the Intel NUC Windows Server 2019 Network Adapter Driver:

Download the latest PROWinx64.exe for Windows Server 2019 from Intel including drivers for the Intel® Ethernet Connection I219-V
To manually install the network drivers, extract PROWinx64.exe to a temporary folder – in this example to the C:\Drivers\Intel\ folder. Extracting the .exe file manually requires an extraction utility like WinRAR or others. You can also run the .exe and it will self-extract files to the %userprofile%\AppData\Local\Temp\RarSFX0 directory. This directory is temporary and will be deleted when the .exe terminates.
The driver for the Intel I219-V network adapter can be found in the C:\Drivers\Intel\PRO1000\Winx64\NDIS68.
Extracted Network Drivers for Windows Server 2019 – Intel NUC PROWinx64
Open Device Manager right click on Ethernet Controller and select Update Driver.
Device Manager Update Driver Ethernet Controller – Intel NUC Windows Server 2019 Driver
Select “Browe on my computer for driver software”, and select “Let me pick from a list of available drivers on my computer”, now you can select Network Adapter.
Update Driver
Click on “Have Disk…” enter the following path “C:\Drivers\Intel\PRO1000\Winx64\NDIS68.”

Driver Location
Now select Intel Ethernet Connection I219-LM (The I219-V version is not shown)
Select the Intel Ethernet Connection I219-LM
And you are done.

Huge thank you again to Michael Williams for sharing that with us. I hope this short blog post provides you a step by step guide on how you can install Windows Server 2019 Network adapter drivers on the Intel NUC. If you have any questions, feel free to leave a comment.

Connect Ubiquiti UniFi Dream Machine to Azure VPN

Posted in Cloud, Hardware, Microsoft, Microsoft Azure

A couple of days ago I got a Ubiquiti UniFi Dream Machine, which is an all-in-one device with an access point, 4-port switch, and a security gateway. After the basic setup, I wanted to connect my Ubiquiti UniFi Dream Machine USG to an Azure VPN Gateway (Azure Virtual Gateway), using Site-to-Site VPN. In this blog post, I am going to show you how you can create a site-to-Site (S2S) VPN connection from your Ubiquiti UniFi Dream Machine to Azure Virtual Network Gateway.

Azure Virtual Network Gateway and Connection

I already have a virtual network in Azure with the address space 10.166.0.0/16, and I also deployed the Azure Virtual Network Gateway connected to that vNet. The next thing I did was to add a connection to the gateway.

Azure VPN Connection

You need the following:

Name for the connection
Set Connection type to Site-to-site (IPSec)
Create a local network gateway (basically the configuration of your local VPN gateway.
Define a shared secret

Configure Ubiquiti UniFi Dream Machine VPN connection

Now you can switch to your UniFI Dream Machine, which has an UniFI USG integrated. Under settings go to Networks and click on Create new Network.

UniFi Network Azure VPN

Here you configure the following:

Name of your VPN connection
VPN Type Manuel IPSec
Remote Subnets which is the Azure vNet address space (in my case 10.166.0.0/16)
Peer IP which is the public IP address of the Azure virtual network gateway
Local WAN IP
the pre-shared key (shared secret)
IPSec Profile: Customized
Key Exchange Version: IKEv2
Encryption: AES-256
Hash: SHA1
DH Group: 2

After that, the VPN will connect and the status of your Azure virtual network gateway connection will change to connected.

Dream Machine Azure VPN Connection

You can now reach your Azure virtual machine using the private IP address range.

Connected Azure VPN

I hope this was helpful and show you how you can connect a Ubiquiti Unifi Dream Machine (USG) to an Azure Virtual Network using a site-to-site VPN connection. If you want to learn more about Azure Virtual Network Gateways check out the following documentation:

Find your Windows 10 IoT Core device on the network

Posted in Cloud, Hardware, Microsoft, Microsoft Azure, PowerShell, Web, Windows, Windows 10, Windows IoT, Work

If you have done the setup of your Windows 10 IoT Core device you can see the name and the IP address on the default app using a HDMI output. If you don’t have a display connected to your device, Microsoft as a cool tool for you to find your device on the network.

When you download the Windows 10 IoT Core Image you also have a installer file called “WindowsDeveloperProgramForIoT.msi”. This installer installs you a tool called Windows 10 IoT Core Watcher, which will discover your Windows 10 IoT Core devices on the network.

You can also open some options directly from that tool:

This is needed for the next steps in this blog series. If you want to know more about Microsoft and Windows IoT check out my first blog post: Microsoft and the Internet of Things.
