Hello!
I’m using EMX Dev. System. I want to make a FTP client uploading data from sd card to remote server. But when I’m trying to get a request stream from sever, program stops(no exceptions throwed). Here is my code:

string path = "ftp://147.32.200.115:1335/readme.txt";

FtpWebRequest ftpreq = (FtpWebRequest)WebRequest.Create(path);
            ftpreq.Method = WebRequestMethods.Ftp.UploadFile;

            ftpreq.Credentials = new NetworkCredential( "user","password");

 ftpreq.UsePassive = false;

 Stream testingsStream = ftpreq.GetRequestStream();// Here the problem begins

          
            FileStream readingStream = new FileStream("SD\\data\\readme.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite);
            int readed;
            byte[] buff = new byte[4096];
            do
            {

                readed = readingStream.Read(buff, 0, 4096);
                testingsStream.Write(buff, 0, readed);
            }
            while (readed != 0);

         
            readingStream.Dispose();
            testingsStream.Dispose();

Any ideas?
P.S.When I changed ftpreq.UsePassive=true NotSupportedException “This version does not support passive mode.” is being thrown. What could it be?

I think I know what it was. I have the FTP server remote and signals from my client in active mode are coming through routers, where my port server want to connect by command PORT is not allowed.

So the question is: When will be possible to EMX module to support passove mode?
