127.0.0.2 address appearing out of nowhere!

Question

I made a trivial console-based chat application to learn RMI and the callback feature. It works when I run it at the same computer, but when I start the server part on the linux box and then try to connect to it with the client part (by specifying the server address 192.168.1.103 as argument) from windows i get this exception:
java.rmi.ConnectException: Connection refused to host: 127.0.0.2; nested excepti
on is:

...so where does this 127.0.0.2 address come from?! I can ping the machines from each other and the firewall on the linux is off. Java on both machines is java SE6
here are my interfaces:
public interface ServerInt extends Remote {
    public void addClient(ClientInt client) throws RemoteException;
    public void removeClient(ClientInt client) throws RemoteException;
    public void publish(String clientID, String msg) throws RemoteException;
public interface ClientInt extends Remote {
    public void notify(String msg) throws RemoteException;
    public String getID() throws RemoteException;
}and here are the main classes that manages objects which implement my remote interfaces (ClientImpl and ServerImpl):
public class ServerMain {
    /** Creates a new instance of ServerMain */
    public ServerMain() {
     * @param args the command line arguments
    public static void main(String[] args) {
        ServerImpl server = new ServerImpl();
        try {
            LocateRegistry.createRegistry(1099);
            ServerInt stub = (ServerInt)UnicastRemoteObject.exportObject(server, 0);
            Registry registry = LocateRegistry.getRegistry();
            registry.bind("MyServer", stub);
            System.err.println("Server ready");
        } catch (Exception ex) {
            ex.printStackTrace();
public class ClientMain {
    /** Creates a new instance of ClientMain */
    public ClientMain() {
     * @param args the command line arguments
    public static void main(String[] args) {
        String host = args[0];
        String clientName = args[1];
        ClientImpl client = new ClientImpl(clientName);
        try {
            Registry registry = LocateRegistry.getRegistry(host);
            ServerInt localStub = (ServerInt) registry.lookup("MyServer");
            UnicastRemoteObject.exportObject(client,0);
            localStub.addClient(client);
            BufferedReader keyboard = new BufferedReader(new InputStreamReader(System.in));
            String userInput = "";
            while(!userInput.equals("quit")){
                userInput = keyboard.readLine();
                localStub.publish(clientName, userInput);
            localStub.removeClient(client);
            UnicastRemoteObject.unexportObject(client, false);
            System.out.println("Connection to Server closed");
        } catch (Exception ex) {
            ex.printStackTrace();
}EDIT: the server is started with java -classpath D:/Java/ -Djava.rmi.server.codebase=file:D:/Java/ callback.ServerMain
and to connect with a client:
java -classpath D:/Java/ callback.ClientMain serverAddr myNick

Sry I was away for the weekend; so the machine's hostname is "revers"; here is what's inside the /etc/hosts file:
# hosts This file describes a number of hostname-to-address
# mappings for the TCP/IP subsystem. It is mostly
# used at boot time, when no name servers are running.
# On small systems, this file can be used instead of a
# "named" name server.
# Syntax:
# IP-Address Full-Qualified-Hostname Short-Hostname
127.0.0.1 localhost
# special IPv6 addresses
::1 localhost ipv6-localhost ipv6-loopback
fe00::0 ipv6-localnet
ff00::0 ipv6-mcastprefix
ff02::1 ipv6-allnodes
ff02::2 ipv6-allrouters
ff02::3 ipv6-allhosts
127.0.0.2 revers revers
Btw I tried the app with another 2 pcs in another network, vista + xp and it worked fine.
