(VB.NET) SCP Upload to a Specific Remote Directory

Demonstrates how to upload a file using the SCP protocol (Secure Copy Protocol over SSH). The file is uploaded to a specific remote directory. It can be either a path relative to the HOME directory of the SSH user account, or an absolute path on the remote filesystem. Obviously, in both cases the SSH user account must have permission to create or overwrite a file in the specified directory.

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:
success = ssh.AuthenticatePw("myLogin","myPassword")
