using ftpWebRequest with an error: the remote server returned error 530 not logged in

Question

I am trying to use the ftpWebRequest in c# my code is

// Get the object used to communicate with the server.
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://192.168.20.10/file.txt");
            request.Method = WebRequestMethods.Ftp.UploadFile;

            // This example assumes the FTP site uses anonymous logon.
            request.Credentials = new NetworkCredential("dev\ftp", "devftp");

            // Copy the contents of the file to the request stream.
            StreamReader sourceStream = new StreamReader(@"\file.txt");
            byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
            sourceStream.Close();
            request.ContentLength = fileContents.Length;
            request.UsePassive = true;
            Stream requestStream = request.GetRequestStream();
            requestStream.Write(fileContents, 0, fileContents.Length);
            requestStream.Close();

            FtpWebResponse response = (FtpWebResponse)request.GetResponse();

            Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription);

            response.Close();

and I get an Error in request.GetRequestStream(); the error is: the remote server returned error 530 not logged in if I try to go in to a browser page and in the url I write ftp://192.168.20.10/ the brows page is asking me for a name and password, I put the same name and password and I see all the files and folders in the ftp folder.

Answer 1

Shouldn't the line:

request.Credentials = new NetworkCredential("dev\ftp", "devftp");

be:

request.Credentials = new NetworkCredential("dev\\ftp", "devftp");

or:

request.Credentials = new NetworkCredential(@"dev\ftp", "devftp");

I have to believe this may be causing your issues because the \f is a form feed character.

Faced the same issue, here's my solution:

request.Credentials = new NetworkCredential(
    usernameVariable.Normalize(),passwordVariable.Normalize(),domainVariable.Normalize());

Hope it helps.

Answer 3

I found out that when connecting via .NET/C# to a FTP-server some characters are not "valid". After setting the login credentials to only contain letters and numbers [a-Z0-9] it worked to log in.

That Worked! Thanks – Mickeymicki

Answer 4

Just remove the double quote from username or password because sometimes $ sign in username or password causes problem. Its good to use single quote every time.

Don not post the same answer to several question. It is probably better then to mark them as duplicate of each other. – Tether

Answer 5

If you assume anonymous logon do not set network credentials. this was the root of my problems.
