Active FTP Connection

Hello,

I currently have a project that will require me to exchange files via FTP. I have to run both a client and server, and both will need to utilize active FTP. I have read up on FTP, and believe I have a fairly good understanding of active vs passive. It would appear that my client will have to issue a PORT command, informing the server as to which data port to connect to. From what I have read, typically the data port on the client is the command port +1. How would I find what port a connection is open? What I have is:

private static Socket CommandSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);        private static Socket DataSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);        private static int DataPort;        public static void SendFile()        {            string RemoteHost = "192.168.1.44";            int RemotePort = 21;            IPAddress RemoteServerIP = IPAddress.Parse(RemoteHost);            IPEndPoint RemoteServerCmdEP = new IPEndPoint(RemoteServerIP, RemotePort);            try            {                Debug.Print("Starting Connection");                CommandSocket.Connect(RemoteServerCmdEP);                Debug.Print("Connected");            }

I know that I am connecting to port 21 on the remote end, but how can I see which port on the ND is utilized to make that connection? I assume that is will be somewhere in CommandSocket.LocalEndpoint, but I cannot seem to find it.

Thanks,

Brandon

i read somewhere the netduino doesent accept multiple connections (only one at a time)

- does it allready work for you ? (the ftp stuff with 2 connections)

The netduino does support multiple connections with it's onboard ethernet. I know the wifly driver doesn't though. Maybe that's why you thought so?

idk where i got that, thx 4 info.
