FTPS / Implicit SSL

See more FTP Examples

Demonstrates how to connect using implicit SSL on port 990. The FTP component connects using SSL on port 990, which is the de-facto standard FTP SSL port. Not all FTP servers support implicit SSL. An alternative is to use AUTH SSL (also called AUTH TLS). VB.NET

Dim success As Boolean = False

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim ftp As New Chilkat.Ftp2

' If this example does not work, try using passive mode
' by setting this to True.
ftp.Passive = False
ftp.Hostname = "ftp.something.com"
ftp.Username = "test"
ftp.Password = "test"
ftp.Port = 990

' We don't want AUTH SSL:
ftp.AuthTls = False

' We want Implicit SSL:
ftp.Ssl = True

' Connect and login to the FTP server.
success = ftp.Connect()
If (success <> True) Then
    Debug.WriteLine(ftp.LastErrorText)
    Exit Sub
Else
    ' LastErrorText contains information even when
    ' successful. This allows you to visually verify
    ' that the secure connection actually occurred.
    Debug.WriteLine(ftp.LastErrorText)
End If


Debug.WriteLine("FTPS Channel Established!")

' Do whatever you're doing to do ...
' upload files, download files, etc...

success = ftp.Disconnect()
