我在 linux 上运行 tcp 服务器，虽然我可以在该服务器上运行 php -f test.php，但我需要从 Windows 客户端执行此操作并返回结果。php 客户端脚本如下所示：

$Host = "192.168.2.70"; 
$Port = 8189;

$Socket = socket_create(AF_INET, SOCK_STREAM, 0) or die ("Error \n ".socket_strerror());
$Result = socket_connect($Socket, $Host, $Port) or die ("Error \n ".socket_strerror(socket_last_error()));

$message = 'CMD1;1;5;0;F;20130426;'."\n";

socket_write($Socket, $message, strlen($message)) or die ("Error \n ".socket_strerror());
$Result = '';

while($buf = socket_read($Socket, 2048 )) {
$Result = $Result.$buf;
}   

socket_close($Socket);
$handle = fopen ('./test.xml', "w");  

fwrite($handle, $Result, strlen($Result));  
fclose($handle);  

?>

和我喜欢的 C# 客户端：

IPAddress ipAddress = IPAddress.Parse("192.168.2.70");
IPEndPoint remoteEP = new IPEndPoint(ipAddress,8189);

Socket sender = new Socket(AddressFamily.InterNetwork, 
                SocketType.Stream, ProtocolType.Tcp );

            try {
                sender.Connect(remoteEP);
                Console.WriteLine("Socket connected to {0}",sender.RemoteEndPoint.ToString());
                byte[] msg = Encoding.ASCII.GetBytes("'CMD1;1;5;0;F;20130426;'.'\n';");
                int bytesSent = sender.Send(msg);

                // Receive the response from the remote device.
                int bytesRec = sender.Receive(bytes);
                Console.WriteLine("Echoed test = {0}",
                Encoding.ASCII.GetString(bytes,0,bytesRec));

不幸的是，它已连接但返回未知命令消息。PHP 脚本在本地工作正常，但来自 Windows 客户端的 C# 不能，有什么提示吗？无法在 linux 中调试服务器代码。

谢谢
