[.NET Remoting] Mixing secure & unsecure channels
- by user305023
I am unable to use an unsecure channel once a secure channel has already been registered. The code below works only if on the client side, the unsecured channel is registered before.
Is it possible to mix secure and unsecure channels without any contraints on the registration order ?
using System;
using System.Collections;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
public class SampleObject : MarshalByRefObject
{
public DateTime GetTest() { return DateTime.Now; }
}
public class SampleObject2 : MarshalByRefObject
{
public DateTime GetTest2() { return DateTime.Now; }
}
static class ProgramClient
{
private static TcpClientChannel RegisterChannel(bool secure, string name, int priority)
{
IDictionary properties = new Hashtable();
properties.Add("secure", secure);
properties.Add("name", name);
properties.Add("priority", priority);
var clientChannel = new TcpClientChannel(properties, null);
ChannelServices.RegisterChannel(clientChannel, false);
return clientChannel;
}
private static void Secure()
{
RegisterChannel(true, "clientSecure", 2);
var testSecure = (SampleObject2)Activator.GetObject(typeof(SampleObject2), "tcp://127.0.0.1:8081/Secured.rem");
Console.WriteLine("secure: " + testSecure.GetTest2().ToLongTimeString());
}
private static void Unsecure()
{
RegisterChannel(false, "clientUnsecure", 1);
var test = (SampleObject)Activator.GetObject(typeof(SampleObject), "tcp://127.0.0.1:8080/Unsecured.rem");
Console.WriteLine("unsecure: " + test.GetTest().ToLongTimeString());
}
internal static void MainClient()
{
Console.Write("Press Enter to start.");
Console.ReadLine();
// Works only in this order
Unsecure();
Secure();
Console.WriteLine("Press ENTER to end");
Console.ReadLine();
}
}
static class ProgramServer
{
private static TcpServerChannel RegisterChannel(int port, bool secure, string name)
{
IDictionary properties = new Hashtable();
properties.Add("port", port);
properties.Add("secure", secure);
properties.Add("name", name);
//properties.Add("impersonate", false);
var serverChannel = new TcpServerChannel(properties, null);
ChannelServices.RegisterChannel(serverChannel, secure);
return serverChannel;
}
private static void StartUnsecure()
{
RegisterChannel(8080, false, "unsecure");
RemotingConfiguration.RegisterWellKnownServiceType(typeof(SampleObject), "Unsecured.rem", WellKnownObjectMode.Singleton);
}
private static void StartSecure()
{
RegisterChannel(8081, true, "secure");
RemotingConfiguration.RegisterWellKnownServiceType(typeof(SampleObject2), "Secured.rem", WellKnownObjectMode.Singleton);
}
internal static void MainServer()
{
StartUnsecure();
StartSecure();
Console.WriteLine("Unsecure: 8080\n Secure: 8081");
Console.WriteLine("Press the enter key to exit...");
Console.ReadLine();
}
}
class Program
{
static void Main(string[] args)
{
if (args.Length == 1 && args[0] == "server")
ProgramServer.MainServer();
else
ProgramClient.MainClient();
}
}
