PowerShell SSH Remoting Linux to Windows

Setup PowerShell SSH Remoting in PowerShell 6

With PowerShell version 6, Microsoft introduced PowerShell Remoting over SSH, which allows true multiplatform PowerShell remoting between Linux, macOS and Windows. PowerShell SSH Remoting creates a PowerShell host process on the target machine as an SSH subsystem. Normally, PowerShell remoting uses WinRM for connection negotiation and data transport, however WinRM is only available on Windows based machines.

There are also some downsides to it. SSH-based remoting doesn’t currently support remote endpoint configuration and JEA (Just Enough Administration). It is also important to understand, that this is not just another PowerShell SSH client.

Use SSH Transport with PowerShell Remoting

To use PowerShell remoting with SSH you can use the same cmdlets, you know from PowerShell remoting with WinRM.

  • New-PSSession
  • Enter-PSSession
  • Invoke-Command

There are 3 new parameters for these cmdlets, if you are using PowerShell SSH remoting.

  • -HostName (Instead of -Computername, you define the SSH target)
  • -UserName (Instead of -Credentials you use the -UserName parameter)
  • -KeyFilePath (If you are using SSH key authentication you can use the -KeyFilePath parameter to point to the key file)


Install or Update PowerShell 6 on Windows 10

How to Install and Update PowerShell 6

Today Windows 10 and Windows Server 2019 ship with Windows PowerShell 5.1 as the default version. PowerShell Core 6 is a new edition of PowerShell that is cross-platform (Windows, macOS, and Linux), open-source, and built for heterogeneous environments and the hybrid cloud. PowerShell 6 today is a side by side version next to Windows PowerShell 5.1. That means on Windows you cannot just upgrade to PowerShell 6, you will need to install it, same as on Linux and macOS. This blog post shows you how simple you can install PowerShell 6 or update PowerShell 6, if you have already installed it, on Windows 10, Windows Server 2019 or Linux.

One great example of how cross-platform PowerShell can work, check out my blog post: How to set up PowerShell SSH Remoting

Of course, you can find excellent documentation out there on Microsoft Docs. However, Steve Lee (Microsoft Principal Software Engineer Manager in the PowerShell Team) shared some one-liner, which helps you quickly install and update PowerShell 6.

Install PowerShell Core 6

Before showing you the one-liner option to install PowerShell 6, I want to share with you the documentation to install PowerShell Core 6 on different operating systems like Windows, macOS, and Linux.



Updated PowerShellGet and PackageManagment

Update PowerShellGet and PackageManagement

Since I am just setting up a new work machine, I wanted to share some information how you can update PowerShellGet and PackageManagement to the latest version. This will give you the usual bug fixes and performance enhancements. Since you don’t get the latest version in Windows PowerShell nor PowerShell Core, you will need to update it manually.

PowerShellGet is a PowerShell module with commands for discovering, installing, updating and publishing the PowerShell artifacts like Modules, DSC Resources, Role Capabilities and Scripts. For example you use PowerShellGet to install the Azure PowerShell module, or other modules.

PowerShellGet module is also integrated with the PackageManagement module as a provider, users can also use the PowerShell PackageManagement cmdlets for discovering, installing and updating the PowerShell artifacts like Modules and Scripts.

How to update PowerShellGet and PackageManagement

Updating to the latest version of PowerShellGet and the PackageManagement module is simple. Since both modules are part of the PowerShell Gallery, you can update them using a couple of simple commands.

You can find both modules in the PowerShell Gallery:

First lets check which versions of the modules you have available. If you use Update-Module, it will automatically load PowerShellGet and PackageManagement and list them as loaded PowerShell modules. Of course you can also use Get-Module -ListAvailable.

PowerShell Modules PowerShellGet and PackageManagement

As you can see, In my default installation, I got PowerShellGet version 1.6.7 and PackageManagement 1.1.7.2. If you have a look at PSGallery, you will see that these are pretty old versions and that there are newer available.

To get the latest version from PowerShell Gallery, you should first install the latest Nuget provider. You will need to run PowerShell as an Administrator for all  the following commands.

If you run PowerShell 5.0 or newer, you can install the latest PowerShellGet using the following command. PowerShell 5.0 is included in Windows 10, Windows Server 2016, Windows Server 2019, any system with WMF 5.0 and 5.1 or a system running PowerShell 6.

Two quick tips, first of, you will need to set the execution policy to RemoteSigned to allow the new module to run. Secondly in some cases you will need to use the -AllowClobber parameter to install the updated version of the module.

You can then use Update-Module to get newer versions:

Updated PowerShellGet and PackageManagment

After that you will see the latest versions of PowerShellGet and PackageMangement available

If you run older versions of PowerShell you can check out the full documention on the PowerShell Docs. I hope this blog post helps you to update PowerShellGet and benefit from the latest versions. If you have any questions, please let me know in the comments.
