Description of Problem:
    The code below operates under windwos but not Linux file is created, but it
is empty. 

    I think that the bug is in 'Credentials' because I can download files on
server without authentication(Login/Password). 

    With my code I was able to download a file on the server
"ftp://ftp-developpez.com/konflor/Latex/formation/FormationLatex.pdf"
anonymously. But on my local server when I want to download a file with a
loggin and a password, my stream "ResponceStream" is empty and there is no
error. My code works on windows and ftp server! My FTP server is not under
windows!


Sorry for my English I am french 




    Sub dl(ByVal remoteFile As String, ByVal localFile As String, ByVal
username As String, ByVal password As String) 


        '1. Create a request: must be in ftp://hostname format, 
        '   not just ftp.myhost.com 
        Dim URI As String = remoteFile 
        Dim ftp As System.Net.FtpWebRequest =  CType(FtpWebRequest.Create(URI),
FtpWebRequest) 

        '3. Settings and action 
        ftp.KeepAlive = False 

        'we want a binary transfer, not textual data 
        ftp.UseBinary = True 

        'Define the action required (in this case, download a file) 
        ftp.Method = System.Net.WebRequestMethods.Ftp.DownloadFile 

        '2. Set credentials 
        if not (username = "" andalso password = "") then 

                ftp.Credentials = New NetworkCredential( username, password) 
        end if 

        '4. If we were using a method that uploads data e.g. UploadFile 
        '   we would open the ftp.GetRequestStream here an send the data 

        '5. Get the response to the Ftp request and the associated stream 
        Using response As System.Net.FtpWebResponse = CType(ftp.GetResponse,
System.Net.FtpWebResponse) 

            Using responseStream As IO.Stream = response.GetResponseStream 

                'loop to read & write to file 
                Using fs As New IO.FileStream(localFile, IO.FileMode.Create) 

                    Dim buffer(2047) As Byte 
                    Dim read As Integer = 0 

                    Do 

                        read = responseStream.Read(buffer, 0, buffer.Length) 

                        fs.Write(buffer, 0, read) 

                    Loop Until read = 0 'see Note(1) 

                    responseStream.Close() 

                    fs.Flush() 

                    fs.Close() 

        End Using 



    End Sub         End Using 

                responseStream.Close() 

            End Using 

            response.Close() 

        End Using 



    End Sub
