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

Dim ssh As New Chilkat.Ssh

' Connect to an SSH server:
Dim hostname As String
Dim port As Integer

' Hostname may be an IP address or hostname:
hostname = "www.some-ssh-server.com"
port = 22

Dim success As Boolean = ssh.Connect(hostname,port)
If (success <> True) Then
    Debug.WriteLine(ssh.LastErrorText)

' Authenticate using login/password:

' in our SCP object.

' mode=0: Download all files
' mode=1: Download all files that do not exist on the local filesystem.
' mode=2: Download newer or non-existant files.
' mode=3: Download only newer files.  
'         If a file does not already exist on the local filesystem, it is not downloaded from the server.
' mode=5: Download only missing files or files with size differences.
' mode=6: Same as mode 5, but also download newer files.
