Environment

The PowerShell script is as follows:

• Listen on local port 9999 through PowerShell.

$host_ip = "127.0.0.1";
$port = 9999;
$Listener = [System.Net.Sockets.TcpListener]$port;
$Listener.Start();
$result = netstat -ano -p tcp | findStr $port | Out-String;

Check whether the listener started successfully

• Check with a PowerShell command.
