[Mono-list] Remoting betweem Mono and MS .NET

I'm using MS.NET 1.1.4322.573 and mono build from mono-daily package from
yesterday (20040621). Your sample application works fine (Server running on
FC1 with mono, client on WIN2003 Server with MS.NET). What version of mono
do you use?
Anyway, are you sure, that you pass the right address as a parameter to the
client? I get this sort of exception, when the the server application is not
running at all (or is running somwhere else as defined by the parameter
passed to the client).

I run a remoting server on Linux, and try to use it from the Windows
Here is my code:

common interface, build as a separate assembly ================== namespace
    public interface ITest{
        string SayHello();

================== Client

using System;
using System.IO;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;

namespace ProofOfConcepts{    
    class Client{
        ITest ar;
        public Client(string host, int port, string endPoint){
            HttpChannel channel = new HttpChannel(0);
            MarshalByRefObject obj = 
                (MarshalByRefObject) RemotingServices.Connect(
                    "http://" +  host + ":" + port + "/" + endPoint);
            ar = (ITest) obj;

        public string SayHello(){
            return ar.SayHello();
        public static void Main(string[] args){
            Client client = new Client(args[0],  60000, "MyEndPoint");
================== Server
using System;
using System.IO;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;

namespace ProofOfConcepts{

    public class AssemblyCache : MarshalByRefObject, ITest{
        public string SayHello(){
            return "hello";
    class RemotingServer{
        public RemotingServer(object obj){
            HttpChannel channel = new HttpChannel(60000);
            MarshalByRefObject mobj = (MarshalByRefObject) obj;
            RemotingServices.Marshal(mobj, "MyEndPoint"); 
        void Listen(){
            Console.WriteLine("Press Enter to exit...");
            Console.ReadLine( );
        public static void Main(){
            AssemblyCache ar = new AssemblyCache();
            RemotingServer rServer = new RemotingServer(ar);

Here is what I get running the client:

Unhandled Exception: System.Net.WebException: The underlying connectio n was

My Mono version is 0.95,  MS .NET version 1.1.4322
