无论是IPC客户端和IPC服务器如何调用共享的远程接口(类继承MarshalByRefObject的)进行通信,而不必把接口类里面注入的应用? 例如,如果我把接口类在被注入到我的目标进程注入库项目,我的注入应用程序不能引用该接口。

由于EasyHook提交66751 (绑EasyHook 2.7阿尔法),它似乎并不可能得到远程接口的实例同时在客户端(即过程发起您的DLL注入)和服务器( 注入的进程中运行你的注入DLL)。
这是什么意思?
那么,在FileMon的和的ProcessMonitor实例中,注意如何共享远程接口( FileMonInterface
,嵌入在Program.cs
,对于菲莱蒙 ,和DemoInterface ,在其自己的文件,为的ProcessMonitor )被放置在注入组件。 FileMonInterface
是在FileMon的项目。 DemoInterface
是在项目的ProcessMonitor。
为什么不是其他回合? 为什么不把FileMonInterface
项目FileMonInject,并把DemoInterface
在ProcMonInject? 因为这时的界面将不再给调用应用程序(FileMon和的ProcessMonitor)访问。
究其原因是因为EasyHook内部使用:
RemotingConfiguration.RegisterWellKnownServiceType(
typeof(TRemoteObject),
ChannelName,
InObjectMode);
这种远程调用允许客户打电话给你的(服务器)接口,但服务器本身(你的应用程序)不能调用它。
解决方案
相反,使用:
// Get the instance by simply calling `new RemotingInterface()` beforehand somewhere
RemotingServices.Marshal(instanceOfYourRemotingInterfaceHere, ChannelName);
我所做的是增加一个重载EasyHook的RemoteHook.IpcCreateServer()接受做NET远程处理我的新“办法”。
它的丑陋,但它的工作原理:
更换整个IpcCreateServer方法(从支架来支撑)用下面的代码。 这里有所示的两种方法。 一个是更详细的过载。 第二个是“原始”的方法调用我们的超载。
public static IpcServerChannel IpcCreateServer<TRemoteObject>(
ref String RefChannelName,
WellKnownObjectMode InObjectMode,
TRemoteObject ipcInterface, String ipcUri, bool useNewMethod,
params WellKnownSidType[] InAllowedClientSIDs) where TRemoteObject : MarshalByRefObject
{
String ChannelName = RefChannelName ?? GenerateName();
///////////////////////////////////////////////////////////////////
// create security descriptor for IpcChannel...
System.Collections.IDictionary Properties = new System.Collections.Hashtable();
Properties["name"] = ChannelName;
Properties["portName"] = ChannelName;
DiscretionaryAcl DACL = new DiscretionaryAcl(false, false, 1);
if (InAllowedClientSIDs.Length == 0)
{
if (RefChannelName != null)
throw new System.Security.HostProtectionException("If no random channel name is being used, you shall specify all allowed SIDs.");
// allow access from all users... Channel is protected by random path name!
DACL.AddAccess(
AccessControlType.Allow,
new SecurityIdentifier(
WellKnownSidType.WorldSid,
null),
-1,
InheritanceFlags.None,
PropagationFlags.None);
}
else
{
for (int i = 0; i < InAllowedClientSIDs.Length; i++)
{
DACL.AddAccess(
AccessControlType.Allow,
new SecurityIdentifier(
InAllowedClientSIDs[i],
null),
-1,
InheritanceFlags.None,
PropagationFlags.None);
}
}
CommonSecurityDescriptor SecDescr = new CommonSecurityDescriptor(false, false,
ControlFlags.GroupDefaulted |
ControlFlags.OwnerDefaulted |
ControlFlags.DiscretionaryAclPresent,
null, null, null,
DACL);
//////////////////////////////////////////////////////////
// create IpcChannel...
BinaryServerFormatterSinkProvider BinaryProv = new BinaryServerFormatterSinkProvider();
BinaryProv.TypeFilterLevel = TypeFilterLevel.Full;
IpcServerChannel Result = new IpcServerChannel(Properties, BinaryProv, SecDescr);
if (!useNewMethod)
{
ChannelServices.RegisterChannel(Result, false);
RemotingConfiguration.RegisterWellKnownServiceType(
typeof(TRemoteObject),
ChannelName,
InObjectMode);
}
else
{
ChannelServices.RegisterChannel(Result, false);
ObjRef refGreeter = RemotingServices.Marshal(ipcInterface, ipcUri);
}
RefChannelName = ChannelName;
return Result;
}

public static IpcServerChannel IpcCreateServer<TRemoteObject>(
ref String RefChannelName,

return IpcCreateServer<TRemoteObject>(ref RefChannelName, InObjectMode, null, null, false, InAllowedClientSIDs);
}
而已。 这就是你需要改变。 你不必改变IpcCreateClient()。
这里是你将如何使用新的重载方法:
假设你有
public class IpcInterface : MarshalByRefObject { /* ... */ }
为您的共享远程接口。
创建它的一个新的实例,并保存其引用。 您将使用这与你的客户沟通。
var myIpcInterface = new IpcInterface(); // Keep this reference to communicate!
这里是你如何创造了前远程通道:
ipcServer = RemoteHooking.IpcCreateServer<IpcInterface>(ref IpcChannelName, WellKnownObjectMode.Singleton, WellKnownSidType.WorldSid);
这里是你会如何现在创建一个远程通道:
ipcServer = RemoteHooking.IpcCreateServer<IpcInterface>(ref IpcChannelName, WellKnownObjectMode.Singleton, myIpcInterface, IpcChannelName, true, WellKnownSidType.WorldSid);
不要忘了...
我得到了这个解决方案这个StackOverflow的职位 。 请务必做,因为他说,并覆盖InitializeLifetimeService返回NULL:
public override object InitializeLifetimeService()
{
// Live "forever"
return null;
}
我觉得这是应该避免了客户端失去了远程接口。
用途
现在,而不是被迫把你的远程接口文件在同一目录下注入的项目,你可以为你的接口文件创建一个特定的库。
该解决方案可能是共同的知识,那些具有NET远程处理这样的经验,但我什么都不知道它(可能已经使用了Word界面错在这个岗位)。
