java - Issue with DSCP marking using setTrafficClass and WireShark -

-

I'm trying to mark DSCP values ​​using setTrafficClass. My servers and clients are installed on two separate machines and I am able to print the cost of DSCP but I can not see it in WireShark. I have gone online through some posts but nothing helped, I am using Windows 7 Professional Any help would be appreciated. Thanks!

I am testing to see how this can be done. Here is the client code:

Try { socket socket = new socket (edit, 2345); Socket.setTrafficClass (10); PrintWriter = New PrintWriter (socket.getOutputStream (), true); Out.println ("Current DSCP Price:" + socket.getTrafficClass ()); Out.close (); Socket.close (); } Hold (exception e) {e.printStackTrace (); }}

Server: 

  try {serverSocket serverSocket = new ServerSocket (1234); Socket ClientSocket = serverSocket.accept (); BufferedReader = New in BufferedReader (New InputStreamReader (clientSocket.getInputStream ())); String fromClient = in.readLine (); Println (fromClient); in.close (); ClientSocket.close (); ServerSocket.close (); } Hold (exception e) {e.printStackTrace (); }}   
 In the console on server side: Current DSCP value: 10  
 My server code and client are on different machines. I  
 I see I:  
 Differential Services Areas: 0x00 (DSCP 0x00: Default; ECN: 0x00: NT-ECT (not ECN-worthy transport))  
 I expect to see a change in wirehark And I only see the default value of zero.   
 
 
 The last time I worked with DSCP values ​​in Java, due to a bug in JVM,  java.net.preferIPv4Stack  The system property had to be set to  true . OVERTHERWARE DSCP PRICES Javascript Despite working in the socket API, the built-in socket will not be set on.  
 In addition to this, you may have to call the  setTrafficClass  before adding the socket, it can not work after a connection on some platforms.  
  java -djava Net.preferIPv4Stack = true ...

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
