SSH Remote Edit File with Visual Studio Code

Remote Edit Files on Azure Linux VMs using VS Code

There are a lot of different ways to remote manage your Azure virtual machines using various tools and technics. In this blog post, I am going to show you how you can remotely edit files on Azure Linux virtual machines using Visual Studio Code. Visual Studio Code has a new Remote Development Extention which allows you to open any folder in a container, on a remote computer, or in the Windows Subsystem for Linux (WSL) and take advantage of the VS Code feature set. With the Remote – SSH extensions, you can easily browse and edit files on an Azure VM or any other system where you can connect using SSH.

Installation

As mentioned to edit the files on the Azure Linux virtual machine remotely, we are using the light-weight, cross-platform, opensource editor Visual Studio Code. You can download and install VS Code from the official website.

Visual Studio Code Remote Development Extension

In addition to Visual Studio code, we need to install the Remote – SSH extension, which comes with Remote Development Extension Pack. This also includes remote extensions for containers or the Windows Subsystem for Linux (WSL).

If you are running on a Windows 10 machine, you will also need to install the OpenSSH client on your machine. You can do that going through this blog post, or by running this command.

# Install the OpenSSH Client
Add-WindowsCapability -Online -Name OpenSSH.Client~~~~0.0.1.0

Azure VM connection using SSH

The Remote – SSH extensions currently only supports connecting to x86_64 Linux-based SSH servers using key-based authentication.

Optional: Create Azure Linux VM with key-based SSH authentication using the Azure CLI

Create Azure Linux VM Azure CLI SSH Keys DNS Name

If you want to try it out, and you haven’t set up a Linux VM SSH and key-based authentication. This Azure CLI command here helps you to create a new Azure virtual machine and sets up ssh keys as well as an optional unique Azure DNS name.

az vm create --resource-group demosshvm --name tomsVM --image UbuntuLTS --admin-username thomas --generate-ssh-keys --public-ip-address-dns-name tomsazurelinuxvm

In this example, you can use the public IP address or the Azure FQDN to connect to the Azure VM. If you have a VPN or Express Route set up, you can also use private IP addresses and DNS names. If you are using public IP addresses in production, make sure you are using a service like Azure Just in Time VM access.

Connect Visual Studio Code to Azure VM using SSH

After you have installed Visual Studio Code, the Remote – SSH extension, the SSH client and have a VM with key-based authentication, you can now easily connect. Open Visual Studio Code, on the bottom left, you see the Remote connection button. If you press it, you will find the remoting options. Select “Remote-SSH: Connect to Host…

Visual Studio Open Remote SSH Connection

This will ask you for the username and IP address or DNS name of the virtual machine. In my case, I am going to use the DNS name.

Visual Studio Code SSH Remoting Connection

 

After pressing enter, this will connect your Visual Studio Code environment to the Azure virtual machine.

Remote edit files on Azure Linux VMs using VS Code

You can start opening folders and files on the remote Azure Linux VM and begin browsing the file system. On the bottom left, you see the name or IP address of the machine you are connected with.

SSH Remote File System Visual Studio Code

You can also open files and start remote edit files on your Azure Linux VM. If you save the changes you made to the file, this is directly saved on the remote Azure virtual machine.

SSH Remote Edit File with Visual Studio Code

You get all the advanced VS Code features you know from your local Visual Studio Code like syntax-highlighting and more.

I hope this shows you an easy way to remotely edit files on your Azure Linux virtual machines using Visual Studio Code and SSH. If you have any questions, please let me know in the comments.



Copy files to Azure VM using PowerShell Remoting

Copy Files to Azure VM using PowerShell Remoting

There are a couple of different cases you want to copy files to Azure virtual machines. To copy files to Azure VM, you can use PowerShell Remoting. This works with Windows and Linux virtual machines using Windows PowerShell 5.1 (Windows only) or PowerShell 6 (Windows and Linux). Check out my blog post at the ITOpsTalk.com about copying files from Windows to Linux using PowerShell Remoting.

Prepare your client machine

Prepare the client machine to create PowerShell Remote connections to a specific remote VM.

Set-Item WSMan:localhost\client\trustedhosts -value "AZUREVMIP"

You can also enable remoting to all machines by using an asterisk.

Set-Item WSMan:localhost\client\trustedhosts -value *

Copy Files to Windows Server Azure VM

If you want to copy files to an Azure VM running Windows Server, you have two options. If you are copying files from Windows to Windows, you can use Windows PowerShell Remoting; if you are copying files from Linux or macOS to Windows, you can use the cross-platform PowerShell 6 and PowerShell Remoting over SSH.

Using Windows PowerShell Remoting

To copy files from a Windows machine to a Windows Server running in Azure, you can use Windows PowerShell Remoting.

Prepare the host (Azure VM) to receive Windows PowerShell remote commands. The Enable-PSRemoting cmdlet configures the computer to receive Windows PowerShell remote commands that are sent by using the WS-Management technology.

Enable-PSRemoting -Force

Now you can create a new PowerShell Remoting session to the Azure VM.

$cred = Get-Credential
 
$s = New-PSSession -ComputerName "AZUREVMIPORNAME" -Credential $cred

After the session was successfully created, you can use the copy-item cmdlet with the -toSession parameter.

Copy-Item .\windows.txt C:\ -ToSession $s

Some important notes

  • You need to configure the Network Security Group for the Azure VM to allow port 5985 (HTTP) or 5986 (HTTPS)
  • You can use PowerShell Remoting over Public Internet or Private connectivity (VPN or Express Route). If you are using the Public Internet, I highly recommend that you use https. I also recommend that you use Just-in-time virtual machine access in Azure Security for public exposed ports.

Using PowerShell Core 6 PowerShell Remoting over SSH

If you are running PowerShell Core 6, you can use PowerShell Remoting over SSH. This gives you a simple connection and cross-platform support. First, you will need to install PowerShell 6. After that, you will need to configure and setup PowerShell SSH Remoting together with OpenSSH. You can follow my blog post to do this here: Setup PowerShell SSH Remoting in PowerShell 6

Now you can create a new PowerShell Remoting session to the Azure VM.

$s = New-PSSession -HostName "AZUREVMIPORNAME" -UserName

After the session was successfully created, you can use the copy-item cmdlet with the -toSession parameter.

Copy-Item .\windows.txt C:\ -ToSession $s

Some important notes

  • You need to configure the Network Security Group for the Azure VM to allow port 22 (SSH)
  • You can use PowerShell Remoting over Public Internet or Private connectivity (VPN or Express Route). Exposing the SSH port to the public internet maybe is not secure. If you still need to use a public SSH connection, I recommend that you use Just-in-time virtual machine access in Azure Security.

Copy Files to Linux Azure VM

Copy File Windows to Linux using PowerShell Remoting

If you want to copy files to a Linux VM running in Azure, you can make use of the cross-platform PowerShell capabilities of PowerShell 6, using PowerShell Remoting over SSH. As for the Windows virtual machines, you will need to install PowerShell 6. Next, you will need to configure and setup PowerShell SSH Remoting together with OpenSSH. You can follow my blog post to do this here: Setup PowerShell SSH Remoting in PowerShell 6

After installing and configuring PowerShell Remoting over SSH, you can create a new PowerShell Remoting session to the Azure VM.

$s = New-PSSession -HostName "AZUREVMIPORNAME" -UserName

After you successfully connected to your Azure VM, you can use the copy-item cmdlet with the -toSession parameter.

Copy-Item .\windows.txt /home/thomas -ToSession $s

I hope this gives you an overview about how you can copy files to Azure VMs using PowerShell Remoting. If you have any questions, let me know in the comments.

How to Install Ubuntu in a Hyper-V Generation 2 Virtual Machine

If you want to install Ubuntu or any other Linux inside a Hyper-V Generation 2 Virtual Machine you need to do a simple change to the VM so you can install it from ISO.  If you create a Hyper-V Generation 2 Virtual Machine and try to start the Virtual Machine, the Virtual Machine will not boot from ISO. This is because of the Secure Boot feature, which is included in Hyper-V Generation 2 Virtual Machines and applies to all Linux operating systems running on Hyper-V.

How to Install Linux in a Hyper-V Generation 2 VM

Create a new Virtual Machine in the Hyper-V Manager

Create Ubuntu Hyper-V Generation 2 Virtual Machine

On the Hyper-V Virtual Machine Generation selection screen, choose Generation 2
