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 = False

Dim socket As ChilkatSocket
socket.Initialize("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
    Log(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 = "mySshPassword"
success = socket.SshAuthenticatePw("sshUser", sshPassword)
If success = False Then
    Log(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
    Log(socket.LastErrorText)
    Return
End If

Log("SSH tunnel closed.")
