As Microsoft announced, SSH will be supported by PowerShell in Windows 10

This is a third-party solution called Posh-SSH. To use SSH in PowerShell, you must first install the Posh-SSH module from the PowerShell Gallery. It is required that Windows 10 is used, or that the Windows Management Framework 5 is installed.

Posh SSH can be installed from PowerShell as follows as Administrator.

Install-Module Posh-SSH
Get-Command -Module Posh-SSH
New-SSHSession -ComputerName "192.168.12.34" -Credential (Get-Credential)
Invoke-SSHCommand -Index 0 -Command "uname -a"

This makes it possible to execute commands on the Linux host and copy files.

Posh-SSH is a PowerShell module for automating tasks against the system using the SSH protocol (OpenSSH). The module supports only a subset of the capabilities defined in RFCs https://de.wikipedia.org/wiki/Secure_Shell.
