• Error #2048: Security sandbox Violation

  I worked on it for almost 2 days now, solid with no luck.  Depletion of each article and the suggestion that I ran across, then I hope that the community can help!  In my quest for an answer to this, I hope he can serve a dual purpose and become useful information for other developers is going in this direction.  For some, you can see the contents and figure TL; DR, but I'm hoping to answer any question that might otherwise span multiple messages.

  The goal is to use a socket "binary" for communication between a Flash application and a custom socket server I'm working.  I soon discovered that you must have a file "crossdomain.xml" to the Flash Application communicate via sockets.

  I develop on Windows 7 64 bits, using Flash Professional CS6, Microsoft Visual Studio 2012 and hosting under IIS.

  Eventually I plan on hosting the Application Flash crossdomain.xml on a remote server, but in order to develop what I wanted to try and keep everything on a single development computer.

  My political module Socket server receives the request for the Flash Application and returns the correct answer.

  Incoming packets using Debug-> Debug Movie--> in Flash Professional:

  GET HTTP/1.1 crossdomain.xml

  Accept: text/xml, application/xml, application/xhtml + xml, text/html; q = 0.9, text/plain; q = 0.8, text/css, image/png, image/jpeg, image/gif; q = 0.8, application/x-shockwave-flash, video/mp4; q = 0.9, flv-application/octet-stream; q = 0.8, video/x-flv; q = 0.7, audio/mp4, application/futuresplash, * / *; q = 0.5

  Incoming packets by using control-> test movie-> in the browser:

  Accept-Language: en-US, en; q = 0.8

  The response that is returned:

  <? XML version = "1.0"? >

  <! DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd" > ""

  < cross-domain-policy >

  < allow-access-from ports = "" * "domain =" * "/ >"

  < / cross-domain-policy >

  At first I wasn't sure if it worked, until I pulled a copy of a violin and looked at the packages being requested and returned.  Initially I had more entries, but as I read more the crossdomain.xml I discovered all the inputs excluded would be lacking at current values so I started to take them off to test crossdomain.xml configurations, that I've run across.

  Return all the XML content through the socket connection did not work, I found out later that I had to create a HTTP header and then add the XML content.

  I was able to confirm the Application Flash Professional CS6 received the crossdomain.xml when I was running the Application in Debug Mode (debug->-> Debug Movie in Flash Professional) and the generated output the following warning:

  Warning: 127.0.0.1 domain does not specify a meta-policy.  'Master only' default meta-policy for the application.  This configuration is deprecated.  See http://www.adobe.com/go/strict_policy_files to solve this problem.

  I know that this is easily fixed by simply using a file as crossdomain.xml:

  <? XML version = "1.0"? >

  < ! DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd" > ""

  < cross-domain-policy >

  < site permitted-cross-domain-policies of control = "master only" / >

  < allow-access-from ports = "" * "domain =" * "/ >"

  < / cross-domain-policy >

  Source ActionScript code:

  private void EstablishConnection(): void {}

  var sock: Socket;

  Security.allowDomain("*");

  Security.loadPolicyFile ("http://127.0.0.1:843 / crossdomain.xml" "");

  socks = new Socket();

  sock.addEventListener (Event.CLOSE, closeHandler);

  sock.addEventListener (Event.CONNECT, connectHandler);

  sock.addEventListener (IOErrorEvent.IO_ERROR, ioErrorHandler);

  sock.addEventListener (SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);

  sock.addEventListener (ProgressEvent.SOCKET_DATA, socketDataHandler);

  sock.connect ("http://127.0.0.1", 8080 ");

  }

  private void closeHandler(event:Event):void {}

  trace ("closeHandler:" + event);

  }

  private void connectHandler(event:Event):void {}

  trace ("connectHandler:" + event);

  }

  private void ioErrorHandler(event:IOErrorEvent):void {}

  trace ("ioErrorHandler:" + event);

  }

  private void securityErrorHandler(event:SecurityErrorEvent):void {}

  trace ("securityErrorHandler:" + event);

  }

  private void socketDataHandler(event:ProgressEvent):void {}

  trace ("socketDataHandler:" + event);

  }

  When I run the Flash Application in debug mode, the following content is displayed in the output window:

  ioErrorHandler: [IOErrorEvent type = "ioError" bubbles = false cancelable = false eventPhase = 2 text = "error #2031: error Socket."] ["URL: http://127.0.0.1"]

  Warning: 127.0.0.1 domain does not specify a meta-policy.  'Master only' default meta-policy for the application.  This configuration is deprecated.  See http://www.adobe.com/go/strict_policy_files to solve this problem.

  securityErrorHandler: [SecurityErrorEvent type = "securityError" bubbles = false cancelable = false eventPhase = 2 text = "" error #2048: security sandbox violation: file:///C|/Source/FlashCS6/AS101.swf cannot load data from http://127.0.0.1:8080. ""]

  [UnloadSWF] C:\Source\FlashCS6\AS101.swf

  Debug the session is over.

  The "ioErrorHandler" is almost instantaneous on the output, while the "securityErrorHandler" takes maybe 10 to 15 seconds before it takes place.  I understand that this is due to the asynchronous nature of the Flash engine.

  When I'm not in the code in the debugger, I noticed that the request to load the policy file does not run as long as the Application is really trying to connect to the defined URL and port.  I think that might be the cause, but not sure.

  In an effort to make this work, I have:

  • Added the SWF and the project file to the global security settings
  • Publication parameters changed in the 'network access only '.
  • added " " http://127.0.0.1 "for Global security settings "
  • Under publication settings, enabled "permit debugging".
  • Adding the inbound and outbound rules in the firewall of Windows 7 to TCP 8080
  • Tried several configurations of crossdomain.xml
  • Check the rules of the "mms.cfg" to ensure that there is no blockage
  • Characteristics of record created and activated in 'mm.cfg', but the log files generated nothing more than what already appeared in Flash Pro CS6 exit window
  • '127.0.0.1' changed 'localhost', get the same results

  On the note of global security settings, I discovered that there are 2 separate places.

  • If you press 'Ctrl + Enter' and right-click your Flash application, "global security settings" here a dialog box of windows with the options that you can configure
  • There is another which is located at the following ADDRESS

  http://www.Macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.htm l #117502

  Do you need to put them both?  I did, in order to solve this.  I guess one comes into play on your local workstation and the other is based on the web only.

  I ran across some references to the Type of sandbox, which could cause potential problems of this kind.  In the trace, until the socket connections are made, I traced the current Type of the Sandbox and it was "localTrusted".

  Another article talked about using your public IP address from your ISP, instead of localhost or 127.0.0.1, but it defeats the purpose of local development.

  I know that the socket communication works on the workstation local, based on 2 trials.  The first being the LoadPolicyFile is run on a socket request and the second being, I tested the Server Socket with a non - Flash Client App communication.

  I am now at a loss and stuck in the mud.  Any help appreciated, and I hope it sheds some light to others going down this same road.

  Thank you.

  Well, the system is not perfect, but it does not work once you lubricate all moving parts with the right oil. =)

  I started by using a sample of Microsoft for asynchronous Server Socket to create a Client and a server, confirming that the system has worked.

  Link: http://msdn.microsoft.com/en-us/library/fx6588te.aspx

  To try to solve this problem, I discovered a policy + socket server written in java.  It's not pretty, but they have a warning on the page saying it is extremely poorly written, but it works.

  Link: http://efreedom.com/Question/1-2951030/AS3-Java-Socket-Connection-Live-Flash-Local-Java

  I had nothing to lose, so I created a restore point, installed the Java SDK and the Eclipse IDE for Java EE Developers.  Created a new project and hacked the sample to match the ports I used and hit 'Play', out of the Flash project and he displayed in a browser.  For the first time, I've witnessed events fire off to connect and close.  In shock now. Laughing out loud.

  After some trial and error with my server, I discovered what needed to change.  The first had to do with how being constituted "AddressFamily.  The order of the day was change the IP for IPEndPoint from a source of an AddressList object (see example of Microsoft) to "IPAddress.Any.  The last item was a bit strange, because the server did not seem to pick up all new connections until I set the listener with MaxConnections.

  Here is a screenshot of the final c# code where the changes have been made.

  IPHostEntry ipHostInfo = null;

  IPEndPoint localEndPoint = null;

  Try

  {

  ipHostInfo = Dns.GetHostEntry (Dns.GetHostName ());

  localEndPoint = new IPEndPoint (IPAddress.Any, _Port);

  _SocketListener = new Socket (localEndPoint.Address.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

  _SocketListener.bind (localEndPoint);

  _SocketListener.listen ((int) SocketOptionName.MaxConnections);

  ...

  It seems relatively simple, but all it takes is 1 config parameter incorrectly and the sails of server at a different level than where the Flash works.

  I founded the NPS server off the coast of the same design.  What I don't understand, is despite the design original not to recognize the connections on the server of a Flash, Flash application policy still caught crossdomain profile that was sent back across port 843.  The content is only available in the engine (a local file does not exist) and I was able to validate this function changes on the crossdomain content sent through and re - compile and restart the server for testing, I did.

  Error #2048 resulted from the Socket server not accepting the connection or to be available for connections.  Once I set the policy server that I was always getting error #2048 until I corrected the Socket server connections.  Initially, I had put a HTTP header to the content of the packet sent with the cross-domain policy, but later I deleted and only send the XML contents now.

  The design I had in mind of all work now.  Multiple connections and communication in real time via sockets.  I have no need for video or audio streaming, data only.  I hope this info helps anyone else who may face the same challenges.

  See you soon!

• Difficulty in communicating through TCP BIS-B socket

  I have tries to establish a TCP via BIS - B connection and run into some problems.  Before describing the situation, I just want to clarify:

  -We are members of the BlackBerry Alliance program;
  -We have received permission to use BIS-B;
  -L'application now works under direct TCP. and
  -L' sample application supplied with the BIS-B information kit works well on the device.

  So, it seems that the camera has access BIS-B and that our application should be able to connect through BIS-B without difficulty.  Previously, I have forwarded this issue to the Alliance but has been achieved here for support, so I will briefly the question not to mention that all aspects of BIS - B covered under the NDA.

  Here's the situation:

  The connection string that I use to create a TCP socket in our program the device server is:
  Socket://IP_ADDRESS:TCP_SERVER_PORT; BIS_B_CONNECTION_STRING

  Where:
  Ip_address is the IP address of the server, the connection program is made for;
  TCP_SERVER_PORT is the TCP port; and
  BIS_B_CONNECTION_STRING is provided to access BIS-B connection string.

  As with direct TCP, the SocketConnection object is created:
  (SocketConnection) Connector.Open (connString, Connector.READ_WRITE);

  Where connString is the above connection string.  Once the connector is created, threads separate send and receive support are started.

  To connect to the server, a packet of 76 bytes of data is written to the socket with OutputStream.write (byte [] b, int off, int len) and rinse with OutputStream.flush ().  Data are received on the server without problem and a 32-byte ACK packet is sent to the server to the device subsequently.

  Here is where the problem appears: the client application on the device never receives the data sent from the server.  Even if the socket has been established and data can be sent on this socket of the device to the server, not a single byte sent from the server to the device is received by the device.  However, when you use TCP direct to establish awareness, data are transmitted between the server and the device without problem.

  This leads me to conclude that one or both of the following ways are produced:

  (1) I'm not creates the socket correctly for a BIS - B connection.

  The examples in the documentation for BIS - B are all for HTTP connections and no demo code is provided to show how a TCP socket should be created.  It is quite possible, there is a minor adjustment for the BIS-B connection string which I am unaware or I create the socket incorrectly.

  (2) my BlackBerry service provider incorrectly configured their BIS-B network connections.

  My device is connected to TELUS and the situation I am facing to sounds a bit like the one described by this man in 2008:

  http://supportforums.BlackBerry.com/T5/General-BlackBerry-smartphone/TELUS-confirmed-BlackBerry-bis-...

  Given that the problem occurs when the data is passed from the server to the device, it seems possible that the IP addresses of device are not properly being NATted on the public address that the server transmits data.  I called people of the TELUS DNA to confirm the BIS-B service is available, but (as the related post described), which does not necessarily eliminate the possibility of a misconfigured NAT.

  So my questions to you people are:

  -If a TCP server program receives data from a device via BIS - B, does indicate that the BIS - B has been correctly established (and so the problem of receiving data server-device is specific to the device or carrier)?

  -J' I am doing something obviously wrong when establishing a TCP via BIS - B socket?

  -Are there a required additional parameter in the connection string (beyond those provided by the HTTP BIS-B connection example) which creates a TCP via BIS - B socket?

  Cause of the problem proved to be the use of InputStream.available () to check the amount of bytes available to entrants on the socket.

  Although InputStream.available () worked well for direct TCP (at least for CDMA Networks), the method returns always 0 when it receives on BIS - B bytes.  As a result, it appeared that the side Server-device of the TCP socket was not receiving data when in fact, the data were available for playback.  With the help of InputStream.read () instead, block and read each byte it received on the socket has resolved the problem.  Given that the incompatible features, I would recommend avoiding the use of InputStream.available ().

  For all those looking at the creation of BIS-B TCP taken in the future, here an answer to my original question:

  The connection string to use to create a TCP socket BIS - B is the same as that shown in the code examples in the RIM for an HTTP connection (examples of code and your BIS - B connection string are received once approval has been given to use BIS-B under the program of the Alliance).

  For example, if your connection string to create a direct TCP socket would be:

  Socket://IP_ADDRESS:TCP_PORT; deviceside = true

  where ip_address is the IP address of your server TCP program and port_tcp is the network port on which traffic is received by the server, you need to replace only the "; deviceside = true' part of your connection string with the string supplied by RIM for your BIS - B connection.  The resulting string would then serve to create a standard TCP socket, such as the following:

  (SocketConnection) Connector.Open (connString, Connector.READ_WRITE);

  where connString is your ' socket: / /... ". ' connection string.

• Communication I/O Stream socket operations

  Hello!

  I want to build a mechanism that opens a socket on a server connection and then independently send and receive messages to and from the server on this connection. My approach is like this: main thread I run a wire (ignition wire) which opens a StreamConnection (socket://iptro, deviceside = true) and get the DataInputStream and DataOutputStream objects out of it. DataInputStream using I create another thread (since reading and writing will be independent - you still wonder if it is possible) for the input data. I use then a mechanism of notification to use received data.

  DataOutputStream is then used to write operations...

  The problem I have:

  Writing seems to be fine as I can see the logs just before and after DataOutputStream writeUTF and hunting methods, but the AutoPlay fails a 'General' IOException. Now, I assumed this StreamConnection can handle the entrance / exit operations... If not, is there a way to do?

  Has anyone done this independent and operations?

• cRIO communication as a PLC with NOR-OPC-Server

  Hello

  I have the task to implement communication between multiple cRIO and NOR-OPC-server. The OPC OR server should act as a data manager for a complex interface.

  I tried the NO-OPC Server and I managed to communicate with the server OPC-NOR as OPC-Client in Windows using a server IO and shared Variables. But the task is to do it on a cRIO. I tried to open a data from a cRIO socket connection to the NOR-OPC-server using a specific URL by using "DataSocket select URL.vi." But as long I do not activate the simulation in the OPC Server - OR-I get errors on the data socket connection opening. If I activate the simulation, which is not the solution, I can write data without error, but the quick OR-OPC-Server Client sees no change for the data label.

  I have the feeling that I am not a good way to get this working. Is there anyone with experience with this? Is data taken one possible at all? It is possible at all? I have to put in place a cRIO-OPC-driver?

  Thank you.

• How to manage the threads for TCP communication?

  Hello

  I have a project to control two separate applications (C++ and LabView) and two of them are implemented as server. Another client program (C++) is used to control applications. Communication between them are implemented using TCP socket. The client program sends the message to start or stop tasks on servers. The client program also sends time (HH) with the message start and end to determine when to start or stop.

  Application in C++ (server): Listening to the request for the connection and when gets one, it creates a thread of communication allowing to manage this and listen again to another connection. Communication wire crossing of handles and messages when it receives a start or a stop message, it creates a thread of timer with the received time to trigger a task at the time specified. And after that he expects the client message. So, here, when the thread (communication, timer) is necessary, it is created.

  In LabView (server): I tried to create the same as the C++ server. But, in manual of LabView and other discussions of the forum, I got that LabView is multithreaded and it can be done with the help of the loop independent. So, I had to create four loops in a diagram:

  1. wait the new connection

  2 manage the communication for the already received connection

  3. start the timer

  4 stop the timer

  and they are executed at the beginning of execution and communication between them are managed using local variables. But, 2, 3 and 4th loop can handle only one connection and it can handle another if the current is closed. The C++ application can handle multiple connections by creating the thread when it is necessary, but not at the beginning of the application.

  Is there a better way to implement this in LabView?

  Is it possible to manage multiple connections and create the diagram node/block (such as a wire) dynamically as C++?

  Thank you.

  There are several ways to do so in modern LabVIEW and you should probably seek the Finder example for TCP examples. The classic is to transfer the refnum of connecting the listening loop in a communications loop that adds to an array of login credentials and then constantly iterates through this array to make the communication. He works on LabVIEW 4.0 perfectly for me even for applications with basic HTTP communication protocol. But you must make sure that the communication for a connection is not delaying his work for reasons that would delay the handling of other connections too, because they are really of course worked on sequentially. If you encounter an error, the connection ID is closed and removed from the table.

  The other is that create you a VI that makes your entire communication and ends on an error or when the order quite. Make this reentrant VI and then launch it through VI server as the instance home, passing the refnum of newly received connection form the listening loop. Then use the method to Run let start and operate as an independent thread.

  For all these, you should be able to find an example in the example Finder when searching for TCP.

• Disable a test socket when executing (Batch Mode)

  We had a model of batch processing with synchronization of batch.   I wonder if it is possible to completely disable one or more of the test socket when running.  I know that the opening screen allows you to choose which sockets are active, but in case something goes astray as the RS-485 communication is inadmissible, I would like to disable one or more at any time during the test.  Thank you in advance for all the ideas come you up with.

• UDP communication with microcontroller

  Hello

  I need to access a controller for some engines. The controller can be accesed by Ethernet. Unfortunately, I know very little such communications.

  So I worked by the UDP-examples of LabView provides. That helped a lot, however, some questions remain:

  What I don't understand is how I'm supposed to open a connection to the controller. In all the examples of LabView you still need to enter the Port number on the server and the ability to use vi. However with the microcontroller, I can't just enter a port number. I guess, that the microcontrroller already has some kind of a port and is similarly to the reciver.vi in the examples, but how can I find the port number or manipulate?

  I found documentation for the microcontroller. It is said that all commands to the microcontroller and the answers will be to send UDP-protocoll text encoded in UTF - 8. The orders correctly decoded will be responded with a package "ACK"and return to the "Commander".»

  The commands are the following:

  overall. Exit = ends the server

  overall. Socket = opens UDP-socket

  overall. IsConnected = responds with 0 or 1, if the port can be used

  global.getPort = returns the port number where the server is listening

  There are more of course. Some for setting up a gerneral I/O-Port and a lot more to move the motors of course. However, I think that the above is those that I need to open a connection.

  Of course, there are child of all that I need. I don't know how to use it. How is it I am destined to one of these commands sent to the controller without having a connection already?

  Do I have to sort of send orders 'everywhere', hope that this device is the only one who responds, ask for its port and then open a connection?

  I am really lost!

  Thanks for your help already!

  Hello

  Thank you very much to all those who helped.

  I managed to make it work, writing type of an own port scanner. The controller has been programmed to send a response to every shipment of order, I wrote a UDP server in LabView that would send a command to the controller that he had to answer. In the 'open UDP', I specified the IP address of my computer's ethernet card, which was connected to the microcontroller only via the crossover cable.

  The server sends the command to an unspecified IP (xFFFFFFFF). First of all to channel 1, then 2-port, etc... and waited for a response. In this way, that I have to know the IP address.

  In the end, the Port number is (of course) 1234.

  Thanks again for your time and all your ideas!

  Secure | (SSL): No. Socket error 11001 error number: 0x800CCC0D

  Hello

  Thanks for posting your question on the Forums of community of Microsoft.
   
  The socket 11001 error occurs when there is failure to post a link to a server to a client through the Internet. This translates the user unable to access a particular site or FTP over the Internet service.

  There are many reasons why a user may receive the socket error. This could mean that there is a change in the host name or has been misspelled. Often, a firewall may block access to the server.

  I suggest you to disable the firewall or antivirus and see if it works.

  Reference:

  Enable or disable Windows Firewall

  http://Windows.Microsoft.com/en-in/Windows-Vista/turn-Windows-Firewall-on-or-off
  Note: Turn off Windows Firewall might make your computer (and your network, if you have one) more vulnerable to damage caused by worms or hackers.

  Disable the anti-virus software

  http://Windows.Microsoft.com/en-in/Windows-Vista/disable-antivirus-software
  Important note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.
