[Mono-list] Remoting

[Wilhelm Patrick]

I got the Remoting System running on Linux->Linux and Windows->Windows (with
MS.NET on Windows and mono on linux), but I got errors when trying
Windows->Linux or Linux->Windows.

Here's the Programm I use for testing:

//Listener.cs
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using NRemotingType;

namespace NRemotingTestServer
{
  public class Listener
  {
    public static void GoListening()
    {
      GoListening(13100);
    }

    public static void GoListening(int port)
    {
      ChannelServices.RegisterChannel(new TcpChannel(port));
      RemotingConfiguration.ApplicationName = @"RemotingTestServer";
 
RemotingConfiguration.RegisterActivatedServiceType(typeof(RemotableType));

      Console.WriteLine("Listening for requests on port {0}. Press Enter to
exit...",port);
      Console.ReadLine();
    }
  }
}

Any ideas what's wrong?

Thank you!
