MDTM:Command not understood

Rohith

Hi,

I am trying to download file from our company's various FTP server's using QNetworkAccessManager by the help of signal

downloadProgress(qint64,qint64)

and all the server's contains authentication, So i have added signal

authenticationRequired(QNetworkReply*,QAuthenticator*)

to perfrom authentication and i also tried another method .

downloadUrl.setUserName("username");
downloadUrl.setPassword("password");
manager.get(QNetworkRequest(downloadUrl));

But i am facing the following errors for each of the server while trying to download from them

Server - 1

The Url is  QUrl( "ftp://(IP)/AA_v3.5.exe" )  
The Url is  QUrl( "ftp://(IP)/AA_v3.5.exe" )

But when i am trying with wget command i am able to download files successfully. Do i need to add anything more in order to avoid errors.

Thanks in advance,
