Open a Forwarded Channel through an SSH Tunnel

See more Socket/SSL/TLS Examples

Demonstrates Socket.SshNewChannel, which opens a port-forwarded channel through an authenticated SSH tunnel to a destination host and port, populating a Socket with the connected channel.

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

set socket = CreateObject("Chilkat.Socket")

'  Connect to the SSH server and initialize an SSH tunneling session.  Port 22 is conventional but
'  not required.
success = socket.SshOpenTunnel("ssh.example.com",22)
If (success = 0) Then
    outFile.WriteLine(socket.LastErrorText)
    WScript.Quit
End If

'  Authenticate the SSH session before opening forwarded channels.
'  The SSH password should come from a secure source rather than being hard-coded.

success = socket.SshAuthenticatePw("sshUser",sshPassword)
If (success = 0) Then
    outFile.WriteLine(socket.LastErrorText)
    WScript.Quit
