<![CDATA[QNetworkAccessManager: How to send data/file from ftp connection]]>I try to send data/file to current directory( folder that I want) from windows to Linux ?
For this Firsltyi I tried to download some file from Linux.
Here is my code:

QUrl url("ftp://192.168.100.70/root/coming.txt");
  url.setUserName("admin");
  url.setPassword("admin");
  url.setPort(21);
  QNetworkRequest request(url);
  manager=new QNetworkAccessManager(this);
  reply = manager->get(request);
  connect(reply, SIGNAL(readyRead()), SLOT(downloadReadyRead()));
  connect(reply, SIGNAL(finished()), SLOT(downloadFinished()));
  qDebug()<<reply->readAll();

and secondly I tried Qt's example download manager and tried:

QNetworkRequest request(url);
  QByteArray applicationUserName = "admin";
  QByteArray applicationUserPassword = "admin";
  request.setRawHeader("Username",applicationUserName);
  request.setRawHeader("Password",applicationUserPassword);
  currentDownload = manager.get(request);
  connect(currentDownload, SIGNAL(downloadProgress(qint64,qint64)),
          SLOT(downloadProgress(qint64,qint64)));
  connect(currentDownload, SIGNAL(finished()),
          SLOT(downloadFinished()));
  connect(currentDownload, SIGNAL(readyRead()),
          SLOT(downloadReadyRead()));

But it returns me:
Failed: Logging in to 192.168.100.70 failed: authentication required

But when I try to connect from fileZilla with this authentication everything is ok.
Do you have any suggestion to me.
What I really want to do is: I want to upload my files into directories that I want from Windows to Linux by ftp connection (exactly like fileZille, almost same but I want to choose ip and path in my code as a hardcode )

I will be plesuare for any help and suggestion.

I got

Downloading ftp://admin:admin@127.0.0.1/root/coming.txt...
[###    ]      0.0 bytes/sec
Succeeded.

Verify the connection stuff saved/specified in your working FileZilla connector. For example, it might be using a different port. Anyway, check that out to make certain your code is trying to do the same.

FTP should accept username and password in the url.
But your first code snippet seems not having right design.
So I think you should use the qt example, but set the username and password in the url as in the first method.

request.setRawHeader("Username",applicationUserName);
request.setRawHeader("Password",applicationUserPassword);
