How to use SSH over PowerShell Remoting

From PowerShell 6 and later SSH can be supported over PowerShell remoting which can use it on Windows or Linux as well.

SSH remoting will do basic PowerShell session between Windows and Linux.

In order to create an SSH connection over a PowerShell remoting you must use the following commands including the new parameter -Hostname instead of Computername.

The prerequisites to establish an SSH Connection over a Powershell Remoting is to install the Powershell 6 or higher and OpenSSH Client and Server to allow remote connection to and from the computer.

Note that if you want only to establish SSH connections from a specific machine you can install only the OpenSSH Client.

But if you want remote connection to and from the machines then you should install both(Server/client).
