DatagramSocket.connect

Hi,

I am trying to find whether a server is running on the remote machine on a specified port.

When the remote server is unreachable, the DatagramSocket.connect(InetAddress, int) always returns without even throwing exception. Even the method DatagramSocket.isConnected also returns true.

socket.connect(hostname, port);

if(!this.socket.isConnected()) {

throw new Exception("Could not connect to Remote server !");

}

socket.send gives me an "ICMP Port Unreachable" exception

Is this how DatagramSocket.connect behaves ?

How can I find whether any valid server is running a remote machine using DatagramSocket ? Is it possible ?
