• DRAC5 "Error when reading the SSL socket connection"?

  Hello

  I have a BIOS of PowerEdge 1950 2.7.0 with DRAC 5 Firmware Version 1.65 (12.08.16).

  When you try to connect to 'Console' I get the error "Error when reading the SSL socket connection".

  I spoke the line "# jdk.tls.disabledAlgorithms = SSLv3, RC4, MD5withRSA, DH keySize.< 768"="" at java.security="" file="" but="" still="" the="">

  I use WIndows 10 with the latest FireFox.

  Thanks in advance,

  Asaf

  I found that these changes were necessary to connect to the DRAC 5 using Chrome and Java 8, rev card. 91:

  In Control Panel > Java > Security:

  1. check "Enable content of java in the browser.

  2. set the security level to "High".

  3. Add each DRAC IP to the list of exceptions

  In C:\Program Files (x86)\Java\jre1.8.0_91\lib\security\java.security):

  Remove MD5:

  jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024
  

  Remove SSLv3, RC4 and MD5withRSA:

• No Socket connection avaialbel

  Hello

  I met a strange on a BB (8820 OS 4.5 AT & T) behaviour when I tried to open the socket connection:

  I disconnected the WIFI device and then tried to open the socket of my application in several ways but non of them works even if I managed to browse the internet (GPRS is shown on main Ribbon of BB).

  I tried to use the following suffixes:

  (1); deviceside = false (for BES connection type)

  (2); deviceside = true (for direct TCP connection type)

  (3); deviceside = true; interface = Wi - Fi (for direct TCP connection with WLAN type)

  I checked the correct APN settings (same as written in 3 different sites) on the BB, but I keep getting error messages such as: timeout 120 sec, invalid tunnel name. When WIFI is connected to the socket is opened successfully and works, but without it, nothing happens.

  Another test I did, I read the link: http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800451/800563/What_Is...

  and tried to add the UID WAP2, I found in the device but I still have the connection timeout.

  Is there a way I can connect without WIFI in such situation?

  I discovered that I used the WAP2 incorrectly so that there was a valid WAP2 entry in full book

  I used it incorrectly and causing the failure of the connections.

• socket connection problem

  Hello

  Here is my code to open a client-side socket connection to a server running on the vmware host I don't know there works well (the server):

  #include
  #include
  #include
  #include
  #include

  int _socket;
  struct sockaddr_in name;

  bool connect (char * ip, int port)
  {
  _socket = socket (AF_INET, SOCK_STREAM, 0);
  If (_socket<>
  {
  Returns false;
  }
  struct hostent * host;
  struct in_addr addr = {0};
  addr.s_addr = inet_addr (ip);
  Host = gethostbyaddr ((char*) & addr, 4, AF_INET);
  Name.sin_family = AF_INET;    Name.sin_addr.s_addr = * ((unsigned long *)-> h_addr host);
  Name.sin_port = htons (port);
  If (bind (_socket, (struct sockaddr *) & name, sizeof (name)))
  {
  Returns false;
  }
  Listen (_socket, 1);
  _socket = accept (_socket, 0, 0);
  Returns true;
  }

  Connect ("127.0.0.1", 44444);

  When you call the connect() method is block on accept() (EEG open Server before the client does). So, I need to know if the question is:

  1_ on my customer code.

  or

  2_ vmware cannot connect to the host computer using the address of the local host computer.

  (or even both)

  You will appreciate all help.

  Thank you.

  After a lot a work around, I realize that the last three

  Methods include the specified address and get ready to listen and

  accept a connection from an unknown client. I mean, it's

  create a server, that is why it stops on the accept() method.
  For example, the code for one side of the client socket should look like this (or almost)

  (similar):

  bool open_connection (char * ip, int port)
  {
  _socket = socket (AF_INET, SOCK_STREAM, 0);
  If (_socket<>
  {
  Returns false;
  }
  struct hostent * host;
  struct in_addr addr = {0};
  addr.s_addr = inet_addr (ip);
  Host = gethostbyaddr ((char*) & addr, 4, AF_INET);
  Name.sin_family = AF_INET;
  Name.sin_addr.s_addr = * ((unsigned long *)-> h_addr_list host)

  [0]);
  Name.sin_port = htons (port);
  If (connect (_socket, (struct sockaddr *) & name, sizeof))

  (name)) )
  {
  Returns false;
  }
  Returns true;
  }

  Then, from the host and the Simulator on a socket connection I

  the same as that used for the loading of the appliction to it.
  One thing: when I try to establish a connection when my computer

  is connected to the internet both the binding and the connection,

• Maintenance of the Socket connections alive

  Hello developers,

  Please, I have problems to perpetuate a socket connection in my application for a long time. It seems to disconnect after a short (2 minutes) while especially if he's inactive.

  It happens that I have write an application with a Chat feature and for that, that I keep a socket connection Alive for the life - tme of my application. I tried stuff like Ping Server every minute, but then this is a leak of resources (Blackberry). Push BlackBerry is not an option (as I have other clients other than BB devices).

  Please someone know how I can fix this or suggest a different way to go about this?

  I agree with previos answering machine. The problem you have is push RIM invented.  I'm not aware of a way around that. If you cannot use the pusher, then you will have to keep alive and if your app will suffer battery drain and possibly additional costs related to data traffic.

  Some people have used email instead of push as a wau to notify the application that there is something to it: this requires a listener e-mail in the application process and eliminate these notification emails.

  If you do not use a living message of keep, then I think this quesiton becomes useless:

• Socket connection in the Simulator with MDS, but not on the curve

  Hello

  Working on an application using socket connections.

  SOC = (SocketConnectionEnhanced) Connector.open ("socket: / /" + address.ip_number + ":" + address.port_number + ";") deviceside = true");

  Proceed to use a DataInputStream and DataOutputStream to communicate.

  The server works, can transmit very well with the Simulator, but also another curve (not same model). (There is a small chance that deviceside = true has not been passed as a parameter when we tested on the curve, which would go through BES? This is probably still there however).

  IMHO, this means the places that the question could be one) how the code is implemented on the client phone or b) phones or their settings (have 4 curve 8530 s on the same CDMA network).

  -These phones have already activated in the last days, is there the chances that something is missing from the service book to allow socket connections? (I doubt that what I downloaded messenger ping I assume uses taken... and everything is fine).

  No authorization application that I put?

  Ideas! Please let your mind flow. Thank you!

  To all those who might find this thread after encountering the same problem:

  The issue was with the DataInputStream... available() was ALWAYS return zero, even if there are more bytes to read. This is our 8530 s curve 4 tests phones. Tried on another curve and "BOLD" and they did not have this problem.

  Use available() stopped and tried reading for much bigger than one of our packages will be (5000 bytes).

  Have some phones to test with 5.0.0.337 that they would not work with that.

  After the 5.0.0.1000 they all work perfectly.

  I read somewhere that the available() issue has to do with J2SE-> J2ME problems, something on a wrapper. This problem exists (or existed) with TSL/SSL apparently (sorry I can't find the thread I get this info, if someone really wants to see him answer and I'll get the link in the history of my browser of laptops).

  Hope this helps someone!

• I have a problem when you try to receive data using the socket connection.

  Hello

  I created a socket connection between a pc (sever, win32) and a blackberry (client) and I have only two questions:

  -When I send a string to the sever I get the unexpected result, I doubt if it's a problem of encoding between platforms.

  -When I try to receive data, (an array of char as a string object), the customer demand freeze (drawing and management of events, so basically the main UI thread), even if I did all the stuff of connection in a separate thread, until I have shut down the server and also no data is received.

  Thanks for your help.

  You treat on the thread of events.

  You have the following code:

  UiApplication.getUiApplication () .invokeLater (new Runnable() {}

  public void run() {}

  try {

  open_connection();

  .....

  Now invokeLater essentially tells the operating system that the associated executable must be run on the event Thread.  You need start a separate Thread.  Extend this Thread, add your code in the run() method, and then start the Thread with start(). (not run()).  Then you must run the networking of processing on a separate Thread.

  This will cause you problems updating the user interface.  Take a look at this help:

  http://supportforums.BlackBerry.com/T5/Java-development/update-a-screen-on-the-main-event-thread/TA-...

  Printing, this means that invokelater a separate Thread is a common misconception.  I recommend you to look at this:

  http://supportforums.BlackBerry.com/T5/Java-development/what-is-the-event-thread/Ta-p/446865

  In addition, I recommend that you take a look at the socketDemo which must be included as a sample-, otherwise you can find it on github:

• in the waking state socket connection problem

  Hi all.
  My app need update real-time security data, it should be able to run well even the switch of the PB in the waking state.
  The problem is that when PB passes to the waking state and more than an hour later, my application cannot send request for data to the socket server (initially he workd well), even when the PB get again enabled, the socket connection is also unnecessary.
  I did a test as follows:
  1, I added the "throttled" in the blackberry - tablet.xml
  2. I have add a few listiner event in the main class, but each of them can be fired in any time.

  QNXSystem.system.addEventListener(qnx.events.QNXSystemEvent.STANDBY,onDeactive);
  QNXSystem.system.addEventListener(qnx.events.QNXSystemEvent.ACTIVE,onActive);
  QNXSystem.system.requestResource(QNXSystemResource.NETWORKING);
  stage.addEventListener(Event.USER_IDLE,userIdle);
  stage.addEventListener(Event.USER_PRESENT,userPresent);
  stage.addEventListener(Event.ACTIVATE,onStageActive);
  stage.addEventListener(Event.DEACTIVATE,onStageDeactive);
  

  3, I put a clock to save information in / shared folder.it worked well in the waking state.

  Thanks for any response.

• Socket connection does not work with SIM network

  Hi all

  I created a socket connection. It works fine when I use the WiFi and iam able to download the data and get a correct answer successfully.   But when I use the network GPRS/SIM I get "Unauthorized response" as an answer. I already check with the default blackberry, here internet browser works very well.

  Can someone tell me why socket connection does not work when I use the SIM card network.

  If anyone knows about internal or the following BlackBerry setting that also tell me

  "Option-> advanced-> TCP Option.

• ON SOCKET CONNECTIONS

  Im trying to make an app that connects 2 o more blackberry without the use of BIS, internet or wifi!... .im trying to do as an intranet and this is possible through a Socket connection, but I don't know what kind of technology should I use, because they ' r 2 just a lot in the tutorials and I don't know which one is the best for what im trying to do, help please?

  Welcome to the forums.

  A Socket connection being basically a TCP/IP connection, I think that the use of sockets fails your condition:

  "without the use of BIS, internet or wifi.

  Given the capabilities of the BlackBerry device, I don't think that you can create a generic intranet using any communication of peer to peer on a BlackBerry smartphone.

  I think it would be useful for you to review some of the many tutorials so that you better understand the platform capacity.

• Problems with 9000 device establishing a socket connection?

  Edit again: still a problem, see Update 2 to end...

  My app works fine on 4.3 & 4.5, device and Simulator. Also works very well in the 4.6 Simulator. However, on the bold new we just acquired today, I can't do the blackberry establish a socket connection. As far as I can tell a call to Connector.open which has the form:

  String connUrl = "socket://:;deviceside=true";StreamConnection sc = (StreamConnection) Connector.open(connUrl);
  

  .. will never return! I set breakpoints after him in the file and I get nothing. There is no sign of a connection through to the other end. I put a breakpoint on the line with Connector.open so I know is to be worn, but if I click on 'no more' control is never returned to the jde debugger.

  I realize in Application 4.6 permissions have been moved around, but I've set manually the application has permission to connect to the internet. I tried to connect to a server, I know that the blackberry can access (e.g. www.google.com), I expect this to cause then an exception more than my application is obviously not HTTP... but nothing! No indication the Connector.open never call does not return. No exception seems also to be thrown, ControlledAccessException or other... can someone guess what might be happening here? It seems that it is a fundamental thing to do, I don't see what could have changed. My thread Manager program is still running behind all that (I see his messages to regular use of ram) isn't as all users of the application are overwritten or anything.

  My request is signed, I checked several times. I can also access the internet as usual from the blackberry browser. It is also interesting to note that, on the debugger to connect to the device, told me debugging information are missing about two - net_rim_cldc and net_rim_os modules if I remember correctly. Then, he said because of this "many debugging features will not work properly", but as far as I can see, willing or not, debug this connection is simply not be established, and yet no exception or anything is up. The above code is surrounded by try/catch that will catch java.io.IOExceptions and ControlledAccessExceptions, among others, but none of this code is already hit. And surely if it was some type of more exotic exception that I have no intention, I would like to at least get a popup on the screen tell me about an uncaught exception?

  Help would be greatly appreciated!

  UPDATE: standard Version, as soon as I had finished my half hour trying to get this thing to work and then wrote a post about the epic forum, he begins to work. Perfectly as I can tell. I guess it could have been a little temporary bad service from my supplier... Oh well anyway we are all good now...

  UPDATE 2: it appears when wifi connections aren't a problem, but if I turn off wifi problem remains. Any ideas?

  How long did you wait for an exception?  It must expire after 2 minutes if it is unable to connect.  Which way you make the connection?  You use the deviceside parameter?

  The BlackBerry has been activated on a BlackBerry Enterprise Server?  You have completed the information under Options, Advanced Options, TCP APN?  The BlackBerry shows 3G on the home screen (capital G)?

  You try to connect using the web port.
  A socket connection uses RIDC, which means you need to use the port of intradoc which 4444 in your case.
  So to change the port number in your connection to 4444 and it should work.

• socket connection - a reward for $30

  I am building an application that uses the socket connection. When the application runs, my desktop, it works fine, however when it is running on a remote server, I get the security sandbox violation: "cannot load data from serverName.com:portNumber."
  
  There is another application on the Adobe (posted by Josh Tynjala) lab that people have the same problem: http://www.zeuslabs.us/archives/6/connecting-to-aim-with-actionscript-3-sockets/
  
  Josh's response was: "you need to run the SWF to a location on your computer."
  
  Its application works well at the local level, but when I upload it to a remote server, I get: "cannot load data from aimexpress.oscar.aol.com:5190." Is it possible to get the socket connection to work on a remote server and not only on the desktop?
  
  I'll give you $30 (using western union or paypal) if someone can get Josh Tynjala application to work on the remote server.

• Problems with the socket connection

  Hello

  I am trying to connect to socket between blackberry and pc Simulator, so that blackberry and pc can talk back.

  However, I found that only the first data sent from blackberry can be received by server successfully.

  When the server tries to turn the blackberry, he failed.  (Survey net.rim.device.cldc.io.ippp.SocketBaseIOException: Connection Timed Out)

  And the blackberry cannot send data to the server successfully.

  I am using BlackBerry MDS Services and write the customer after the demonstration ConnectThread.

  When debug that code in my client side for real device, it can be connected with the server, can receive data.

  but in wireless its does not work, my client cant find the serversocket IP...

  So someone tell me how can I get these things for wireless...
