Hmm - isn't a socket a combination of an IP address and a port? So if 
the socket is broken, then and it doesn't matter if the packet is sent with 
UDP or TCP - one would expect the service to be broken too? 

It's a "Unix domain socket" a socket?

class DatagramClient {
    public static void main(String argv[]) {
	if (argv.length!=2) {
	     System.out.println("java DatagramClient <hostname> <port#>");
	     return;
	}
	try {
	    int port = Integer.parseInt(argv[1]);
	    InetAddress in = InetAddress.getByName(argv[0]);
	    // InetTuple tup = new InetTuple(in, atoi(argv[1]);
	    DatagramSocket s = new DatagramSocket();
	    byte buf[] = new byte[10];
	    for (int i=0; i<buf.length; ++i) buf[i] = (byte)i;
	    DatagramPacket dp = new DatagramPacket(buf, 10, in, port);
	    s.send(dp);
	    s.close();
	} catch (Exception e) {
		System.out.println("Something bad happened.");
	}
    }
}
