When IPv6 is enabled on Suse 9 (or JDS 3) it is not possible
to bind a ServerSocket to the local address.
App receives a "cannot assign requested address" error

Just in case.., test case is here:
============ TestCase ===========

import java.net.*;

public class TestServer {

 public static void main(String[] args) throws Exception {

   if (args.length != 2) {
     System.out.println("Usage: java TestServer <host_address_ipv6> <port>");
     System.exit(1);
   }

   System.out.println("Host Address="+args[0]);
   System.out.println("Port        ="+args[1]);

   ServerSocket ss = new ServerSocket();

   ss.bind(new InetSocketAddress(InetAddress.getByName(args[0]), 
  	Integer.parseInt(args[1])));

   System.out.println("ServerSocket Bound");

   ss.accept();
 }
}
java TestServer <host ipv6 address> <port>

for host use local link-local address of the host port 5555

Verify:

On success, the server socket will be bound to the specified address and port. O
n failure some exception will be thrown. For
SuSE Linux ES 9.0, following is thrown:

Exception in thread "main" java.net.BindException: Cannot assign requested addre
