Question:

Cannot connect to IPSwitch WS_FTP (SFTP) using chillkat version 9.5.0.68

Sep 05 '17 at 08:44

I'm having a problem to connect to the IPSwitch SFTP Server.

This is the sample code i'm using in my program.

success = sftp.Connect(hostname, port)

It return false when it reach the line above.

                Dim port As Integer
                Dim hostname As String
                hostname = tempArrUrl(2) 'ftpServer
                port = CInt(strPort)

                '  Load a .ppk PuTTY private key.
                Dim puttyKey As New Chilkat.SshKey()
                Dim ppkText As String = puttyKey.LoadText(puttyloc)

                '  "secret" is the actual password for the above PPK.
                puttyKey.Password = puttyPW
                success = puttyKey.FromPuttyPrivateKey(ppkText)
                If success <> True Then
                    log.fErrorLog(sftp.LastErrorText & "-SFTPTest -  Failed to Load Putty Key - " & trackNo)
                End If

                '  Connect to an SSH/SFTP server
                ***success = sftp.Connect(hostname, port)***
                If success <> True Then
                    log.fErrorLog(sftp.LastErrorText & "-SFTPTest -  Failed toConnect to Server - " & trackNo)
                End If

Answer

Please post the hostname or IP address and port number (if different than 22) so that I can reproduce the problem (or send the hostname/IP to support@chilkatsoft.com).

Answer

I'm using localhost as hostname with port number 22 for testing on local pc.
