(AutoIt) Multiple Hop SSH to SFTP

Demonstrates how to SFTP through an intermediate SSH server (multiple hop). The scheme looks like this:

Application => ServerSSH1 => ServerSFtp

The ConnectThroughSsh method is added in Chilkat version 9.5.0.55 to accomplish this task.

$oSsh1 = ObjCreate("Chilkat.Ssh")

; Hostname may be an IP address or domain name:
Local $sHostname = "192.168.1.111"
Local $sPort = 22

; Connect directly to the 1st SSH server:
Local $bSuccess = $oSsh1.Connect($sHostname,$sPort)
If ($bSuccess <> True) Then
    ConsoleWrite($oSsh1.LastErrorText & @CRLF)
    Exit
EndIf

; Authenticate using login/password:
$bSuccess = $oSsh1.AuthenticatePw("myLogin","myPassword")
If ($bSuccess <> True) Then
    ConsoleWrite($oSsh1.LastErrorText & @CRLF)
    Exit
EndIf

; Connect through the 1st SSH connection to reach a 2nd SSH server (for SFTP)
; Note: Any number of connections may be simultaneously tunneled through a single
; existing SSH connection.
$oSftp = ObjCreate("Chilkat.SFtp")

; Connect to some SSH/SFTP server through ssh1.
$bSuccess = $oSftp.ConnectThroughSsh($oSsh1,"sftp.someremoteserver.com",22)
If ($bSuccess <> True) Then
    ConsoleWrite($oSftp.LastErrorText & @CRLF)
    Exit
EndIf

; Authenticate with the SFTP server. 
$bSuccess = $oSftp.AuthenticatePw("myLogin","myPassword")
If ($bSuccess <> True) Then
    ConsoleWrite($oSftp.LastErrorText & @CRLF)
    Exit
EndIf

; After authenticating, the SFTP subsystem must be initialized:
$bSuccess = $oSftp.InitializeSftp()
If ($bSuccess <> True) Then
    ConsoleWrite($oSftp.LastErrorText & @CRLF)
    Exit
EndIf

; Upload from the local file to the SSH server.
; Important -- the remote filepath is the 1st argument,
; the local filepath is the 2nd argument;
Local $sRemoteFilePath = "hamlet.xml"
Local $sLocalFilePath = "c:/temp/hamlet.xml"

$bSuccess = $oSftp.UploadFileByName($sRemoteFilePath,$sLocalFilePath)
If ($bSuccess <> True) Then
    ConsoleWrite($oSftp.LastErrorText & @CRLF)
    Exit
EndIf

ConsoleWrite("Success." & @CRLF)

; Close the connection with the SFTP server.(This closes the the tunnel through ssh1.)
; The connection with ssh1 is still alive, and may be used for more connections.
