Bug? Already logged in. (code=530)

Question

Hello,

On some ftp-servers i got the error message, on others not. The code is ervy time the same:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Ftp As New EnterpriseDT.Net.Ftp.FTPConnection

Ftp.Timeout = 120
Ftp.ConnectMode = EnterpriseDT.Net.Ftp.FTPConnectMode.PASV
Ftp.ServerAddress = "x.x.x.x"
Ftp.ServerPort = "21"
Ftp.UserName = "xxx"
Ftp.Password = "xxx"

Try
Ftp.Connect()
Ftp.Login()
Catch ex As Exception
MsgBox(ex.Message)
End Try
Ftp.Close()

End Sub

Is there any solution? thx.

Hi Bruce

Could you please enable logging (see Developer's Guide) and post the relevant parts of the log?

I added the debug code in this way:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Ftp As New EnterpriseDT.Net.Ftp.FTPConnection

Dim log As Logger = Logger.GetLogger(GetType(Form1))
Logger.CurrentLevel = Level.DEBUG
log.AddAppender(New FileAppender("d:\test_ftp.log"))

log.Info("start")

Ftp.Timeout = 120
Ftp.ConnectMode = EnterpriseDT.Net.Ftp.FTPConnectMode.PASV
Ftp.ServerAddress = "x.x.x.x"
Ftp.ServerPort = "21"
Ftp.UserName = "xxx"
Ftp.Password = "xxx"

Try
Ftp.Connect()
Ftp.Login()
Catch ex As Exception
MsgBox(ex.Message)
End Try
Ftp.Close()
log.Info("end")
End Sub




The Result-Log contains:

Answer 3

With FTPConnection there is auto login by default, so after Connect() you don't need to call Login().
