Close an SSH Tunnel

See more Socket/SSL/TLS Examples

Demonstrates Socket.SshCloseTunnel, which closes the SSH tunnel opened by SshOpenTunnel and terminates its forwarded channels.

Dim success As Boolean
success = False

Dim socket As New 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 = False) Then
    System.DebugLog(socket.LastErrorText)
    Return
End If

//  Authenticate the SSH session before opening forwarded channels.
//  The SSH password should come from a secure source rather than being hard-coded.
Dim sshPassword As String
sshPassword = "mySshPassword"
success = socket.SshAuthenticatePw("sshUser",sshPassword)
If (success = False) Then
    System.DebugLog(socket.LastErrorText)
    Return
End If

//  Close the SSH tunnel and terminate its forwarded channels.  This does not affect unrelated SSH
//  objects or connections.
success = socket.SshCloseTunnel()
If (success = False) Then
    System.DebugLog(socket.LastErrorText)
    Return
End If

System.DebugLog("SSH tunnel closed.")
