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

common interface, build as a separate assembly
==================
namespace ProofOfConcepts{
    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);
            ChannelServices.RegisterChannel(channel);
            MarshalByRefObject obj = 
                (MarshalByRefObject) RemotingServices.Connect(
                    typeof(ProofOfConcepts.ITest),
                    "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");
            Console.WriteLine(client.SayHello());
        }
    }
}
================== 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);
            ChannelServices.RegisterChannel(channel);
            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);
            rServer.Listen();
        }
    }
}
==================

Here is what I get running the client:


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

My Mono version is 0.95,  MS .NET version 1.1.4322
