Now, we will access Ubuntu via PowerShell on Windows Server 2016.

Install OpenSSH in Windows 2016.

Follow the link below to download OpenSSH-Win64-8.9.10.msi. Then double click to install OpenSSH.

https://github.com/PowerShell/Win32-OpenSSH/releases/tag/v8.9.1.0p1-Beta

An OpenSSH folder is created under C:\Program Files\OpenSSH directory.

We create a PS session from Windows Server 2016 to Linux Ubuntu (ubuntu-desktop.cisa.local) via OpenSSH.

$session = New-PSSession -HostName ubuntu-desktop.cisa.local -UserName tung -SSHTransport

The error message happens because the cmdlet doesn’t find the ssh.exe file.

To solve the issue:

Add the OpenSSH path into environment variable and restart Windows 2016 server

OR copy ssh.exe to C:\Windows and C:\Windows\System32 directory.

Establish a PS connection to Linux Ubuntu via OpenSSH.

$session = New-PSSession -HostName ubuntu-desktop.cisa.local -UserName tung -SSHTransport
Enter-PSSession $session
Invoke-Command -Session $session -ScriptBlock {Get-Process}
Invoke-Command -Session $session -ScriptBlock {ip a}
Invoke-Command -Session $session -ScriptBlock {netstat -antp}
