Why do i get a RMI ConnectException ?

Question

i have a simple client server application where the server class is implemented by
a class called AgentA, as shown below. Agent A will provide a form to the client when the getForm() method is invoked by the client. the program runs fine on my PC at home which runs on windows xp, but it doenst run on linux.
/**SERVER CLASS*/
import java.rmi.server.UnicastRemoteObject;
import java.rmi.Naming;
import java.rmi.RMISecurityManager;
import java.rmi.RemoteException;
import java.net.MalformedURLException;
import java.rmi.*;
public class AgentA extends UnicastRemoteObject implements HasDataInterface {
     /** exports object, to allow it to receive incoming client requests*/
     public AgentA()throws RemoteException{
          super();
          System.out.println("Creating server Object");
/** returns an input form to the client when invoked */
     public void getForm() throws RemoteException{
          System.out.println(" get form");
/** instantiates the input form, where the form is a simple
gui type form
          Form f = new Form();
public static void main(String args[]){
     try{
          AgentA ag= new AgentA();
/**this line doesnt work properly i think*/
          Naming.rebind("rmi://138.37.94.101:5577/Server",ag);
               System.out.println("Server Ready");     
          catch(Exception e){
               System.out.println("error : " + e.getMessage());
          System.out.println("finish");
The Server program (Agent A) prints 'finish' but never terminates.
Ive tried to use the folowing replacements:
Naming.rebind("rmi://:5577/Server",ag);
Naming.rebind("rmi://ip address:5577/Server",ag);
i have also tried using the bind() method instead but this doesnt make any differnce.
Naming.rebind("rmi://ip address:5577/Server",ag);
i get this error when i compile my client class
Connection refused to host: 138.37.94.101; nested exception is:
java.net.ConnectException: Connection refused
I would very much appreciate if some one could put me out of my misery!!!

Sorry for not mentioning it before, but at the moment for simplicity reasons i am running the client and server program on the same PC. So the form at the moment will be displayed to me, as the server and client programs are on the same machine. Obviously i need to change this in the future. I randomly chose port 5577, as this was a port unused on my linux machine which is running over a network. The default port 1099 was already in use, so i chose 5577. I am still baffled why the Naming call isnt working on linux. I thought that the Naming call's format was as follows :
Naming.rebind("protocol//host:port/objectname", object);
where objectname is a simple String name to uniquely identify each object in the registry .
I hope this will help provide enough information for someone to help me in my moment of crisis!
