New Post: PortForwading Bug

Hi,

I detected a problem when using PortForwading.

The first time, the tunneling is working properly, but after closing, the forwading rule is still working,

 ' RENCI
    Dim client As SshClient
    Dim port As ForwardedPortLocal

    Public Sub SSHDisconnect(ByRef _client As SshClient, ByRef _port As ForwardedPortLocal)
        _port.Stop()
        _client.Disconnect()
        _client.RemoveForwardedPort(_port)
    End Sub

I use this sequence for open:

 Public Function SSHConect(ByRef _client As SshClient, ByRef _port As ForwardedPortLocal, _SSHIPserver As String, _SSHPortServer As Integer, _SSHForwardIP As String, _SSHForwardPort As Integer) As Boolean
        If (Not IsNothing(_client)) Then
            If (_client.IsConnected) Then
                '_port.Stop()
                '_client.RemoveForwardedPort(_port)
                _client.Disconnect()
            End If
        End If
        SSHConect = False
        _client = New SshClient(_SSHIPserver, _SSHPortServer, "userssh", "1111aA")

        _client.KeepAliveInterval = New TimeSpan(0, 0, 30)
        _client.Connect()
        _client.SendKeepAlive()


        If _client.IsConnected Then
            Try
                _port = New ForwardedPortLocal("127.0.0.1", _SSHForwardPort, _SSHForwardIP, _SSHForwardPort)
                _client.AddForwardedPort(_port)
                _port.Start()

                If (_port.IsStarted) Then
                    SSHConect = True
                Else
                    SSHConect = False
                End If

            Catch ex As Exception
                MessageBox.Show(ex.ToString())
                SSHConect = False
            End Try
        End If
    End Function

When connection is established first time is possible to SELECT from SQLServer database without problems.

_port = New ForwardedPortLocal("127.0.0.1", 14444, _SSHForwardIP, 1433)
and _port.IsStarted is True

After close connection and open to another SSH server, the first portforwading rule is still running, and the next rule doesn't works.

This is the state for second time with connecting to a new ssh server ip, connected state is true.



Any idea how to repair??
