Hi,
these are TCP client and server which can simply used for testing if a specific TCP port is open
This is the server side. It listens at port 4444
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | # Server$iPort = 4444$TCPListener = New-Object System.Net.Sockets.TcpListener($iPort)$TCPListener.Start();[byte[]]$ReadBytesBuffer = New-Object byte[] 65536# Here the code waits for an incoming connection$TCPServer = $TCPListener.AcceptTcpClient();write-host ("Connected from {0}" -f $TCPServer.Client.RemoteEndPoint.ToString())$TCPServerDataStream = $TCPServer.GetStream()do{ try { $iBytesRead= $TCPServerDataStream.read($ReadBytesBuffer , 0, $ReadBytesBuffer.Length) $TCPServerDataStream.Write([System.Text.Encoding]::Ascii.GetBytes('OK'),0,2) write-host ([text.encoding]::ASCII.GetString($ReadBytesBuffer ,0,$iBytesRead)) } catch { write-host ("Cannot read data from stream. Error: {0}" -f $_.Exception.Message) }}while($TCPServer.Connected)write-host "Connection closed"$TCPServerDataStream.Close()$TCPServerDataStream.Dispose()$TCPServer.Close()$TCPServer.Dispose()$TCPListener.Stop() |
And the client side
1 2 3 | [Net.Sockets.TCPClient]$TCPClient=New-Object System.Net.IPEndpoint ([ipaddress]::any,0)$TCPClient.Connect("localhost",4444) $TCPClientDataStream = $TCPClient.GetStream() |
Then you can send data multiple times from the client over the connection
1 2 | $Data = [System.Text.Encoding]::Ascii.GetBytes('Message to TCP Server') $TCPClientDataStream.Write($Data,0,$Data.length) |
Then close the connection
1 | $TCPClient.Close() |
