B4J Question [Solved]FTP Download file from IONOS Hidrive

[schimanski]

Does anyone have experience with IONOS FTP? I have enabled the FTP protocol, but unfortunately I can't access the files. Do I need to use a different configuration?

Private Sub B4XPage_Created (Root1 As B4XView)
    FTP.Initialize("FTP", "sftp.hidrive.ionos.com", 22, "[email protected]", "xxxxxx")
    FTP.UseSSL=True
    FTP.TimeoutMs=5000
    FTP.List("/")
End Sub

Sub FTP_ListCompleted (ServerPath As String, Success As Boolean, Folders() As FTPEntry, Files() As FTPEntry)
    Log(ServerPath)
    If Success = False Then
        Log(LastException)
    Else
        For i = 0 To Folders.Length - 1
            Log(Folders(i).Name)
        Next
        For i = 0 To Files.Length - 1
            Log(Files(i).Name & ", " & Files(i).Size & ", " & DateTime.Date(Files(i).Timestamp))
        Next
    End If
End Sub

if is set UseSSL to true, i get this exception:

(SSLException) javax.net.ssl.SSLException: Unsupported or unrecognized SSL message

Without setting UseSSL to true

(SocketTimeoutException) java.net.SocketTimeoutException: Read timed out

with setting UseSSLExplicit to true on port 21:

(ConnectException) java.net.ConnectException: Connection refused: connect

The configurations of the IONOS Hidrive FTP from the manual:

Bezeichnung	SFTP	FTPS
Server	sftp.hidrive.ionos.com	ftp.hidrive.ionos.com
Benutzername	Ihr HiDrive-Benutzername	Ihr HiDrive-Benutzername
Passwort	Ihr HiDrive-Passwort	Ihr HiDrive-Passwort
Port	22	21 (explizit mit TLS-Verschlüsselung)

It is no problem, to use it with Filezilla.

You should connect to the server ftp.hidrive.ionos.com instead of sftp.hidrive.ionos.com. and port set to 21
ftps is not sftp.

Thanks you, for your answer. I tried different configurations. With the following, the ListCompleted is success, but the list of folder and files are always emty, even if I specify the directories explicitly:

    FTP.Initialize("FTP", "ftp.hidrive.ionos.com", 21, "[email protected]", "xxxxx")
    FTP.UseSSLExplicit=True
    FTP.TimeoutMs=5000
    FTP.List("\")
    
End Sub

Sub FTP_ListCompleted (ServerPath As String, Success As Boolean, Folders() As FTPEntry, Files() As FTPEntry)
    Log(ServerPath)
    If Success = False Then
        Log(LastException)
    Else
        Log(Folders.Length)
        Log(Files.Length)
        For i = 0 To Folders.Length - 1
            Log(Folders(i).Name)
        Next
        For i = 0 To Files.Length - 1
            Log(Files(i).Name & ", " & Files(i).Size & ", " & DateTime.Date(Files(i).Timestamp))
        Next
    End If
End Sub

Have you tried to use passivemode?

[B4X] Tip: Always set FTP.PassiveMode to True

I've just wasted an hour trying to understand why a desktop program that I'm using for many months failed to upload a file to a FTP server. I realized that the only thing that was recently changed is that B4J was running with Java 10. Mistakenly I assumed that it is related to IPv6 handling (the...

The same result.

the ListCompleted is success, but the list of folder and files are always emty, even if I specify the directories explicitly:

It has worked

The same result.

try doing

FTP.List(".")

 

[schimanski]

That's it. I hadn't thought of it. Thank you. That's the code:

    FTP.Initialize("FTP", "ftp.hidrive.ionos.com", 21, "[email protected]", "xxxxxx")
    FTP.PassiveMode=True
    FTP.UseSSLExplicit=True
    FTP.TimeoutMs=5000
    FTP.List(".")

and here the result:

.
2
0
public
users

Perfect!
