PowerShell cmdlet Test-NetConnection not available - powershell

Question

I noticed that the cmdlet Test-NetConnection was not installed on Server 2012. Since Server 2012 comes with PowerShell version 3 so I thought it might help to update to the latest version 5.1.
I did the update but the cmdlet Test-NetConnection is still not available.
Only Test-Connection is present, but I need Test-NetConnection to test ports.
How can I get Test-NetConnection now?

Answer 1

The availability of many cmdlets is tied to the Windows version, not the PowerShell version. If you can't upgrade your Windows version you can't have Test-NetConnection.
You could use a commandline port scanner like nmap or scanline for port tests, or you could connect to the port(s) yourself:
function Test-Port($server, $port) {
$client = New-Object Net.Sockets.TcpClient
try {
$client.Connect($server, $port)
$true
} catch {
$false
} finally {
$client.Dispose()
}
}

Answer 2

$ipaddress = "serverName"
$port = "portNum"
$connection = New-Object System.Net.Sockets.TcpClient($ipaddress, $port)
if ($connection.Connected) {
Write-Host "Success"
} else {
Write-Host "Failed"
}
