Force Disconnect

[Phreak]

Is it possible, if I have a TCPListener running, and it has multiple connections to it; to force disconnect one of the connections?

Example:

 

Billy, Jimmy, and Tommy all just connected to it (in that order), and Billy didn't supply the correct syntax for logging on (potential hacker); is there a way to have the TCPListner or something, disconnect that specific connection?

You call the Close method of the TcpClient object returned by TcpListener.AcceptTcpClient.

Now you lost me, call the Close method of the TCPClient on the server application that is created by the TCPListner.AcceptClient? Pardon my asking how I would do that? Or do you know of somewhere that goes over this topic?

Well, the TcpClient object that is returned is passed to a Client object from my Client class.

 

Dim x As New Client(mobjListener.AcceptTcpClient)

 

So I made the Client class inherit from TcpClient, and when my Disconnected event was raised (I raised it), the client object is passed to it, and I call the Close method, however it doesn't disconnect. Here is that code:

 

Private Sub OnDisconnected(ByVal sender As Client)
       sender.Close()
       UpdateStatus("Disconnected")
       mcolClients.Remove(sender.ID)
   End Sub

 

Any other ideas? Anyone?
