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)
