Socket TCP detecting disconnections

• Allowing my goal (cRIO) detect disconnection of LAN with host

  Dears

  I develop a standalone application using sbRIO (with RT VI and VI FPGA) and logging data to a host (Host VI) PC...

  the fact is that I need my RT goal to detect if a LAN disconnect has occurred (for example the host pc crashed), he should do a collection of certain data until the connection to the local network is retrieved...

  I don't know if there is something similar to ping between the RT and the host which is done periodically to check the connectivity?

  Help!

  Thanks in advance

  Why not sent a message of "pulse" every second. In this way, if the heart rate does not occur after a certain period, the collection of local data may occur.  Other messages can be sent to recover local data and restore the streaming data.

• Detect disconnect NetStream

  Hello

  When two instances of Flash Player are directly connected via NetStream, is there a way to know when the other has disconnected (for example, by closing her browser)? I see nothing in NetStatusEvent.info.

  Thank you

  Rob

  You should get a NetStream.Connect.Closed sent to the event of the NetConnection instance listener.  Event.info.Stream will be the flow of specific peer.

• TCP/IP visa write stop character

  Dear all,

  I did an application with LabView where I communicate to my instrument via RS232. I use the VISA command.

  This application works OK.

  Now, here's my problem, my instrument also have an ethernet interface, so I want to be able to communicate using TCP/IP socket.

  The problem is that I have not found in the properties of socket TCP/IP, an equivalent to the 'Mode' end for the Scriptures of the serial property.

  If I want my instrument understand that I send, I need to add a 0x0A character to the string sent. When I use the RS232 interface, this is done by "mode of end for the Scriptures.

  I would like to avoid manually adding a 0x0A when I connect by Ethernet in my entire program because it is quiet big.

  You have an idea?

  Thanks a lot for your help.

  Best regards

  The 'end' is defined in 488.2 as EOI which is actually one of the lines of control. This is why the help information are a little confusing for me. I know that with GPIB functions you can optionally add a LF or CR to the IDE and it is also something that can be set in MAX when you configure a GPIB card. According to me, the default value is not character and I looked for a VISA property that would do something similar, but did not find anything specific to change the character of 488 end. I was hoping that the stop character was the same thing but I don't think. I hope that someone with a deeper insight into the VISA will respond.

• Socket RAW InputStream.availalble () in stream wireless network always 0?

  For all BlackBerry networking expert out there.

  The explanation of the problem will be quite long, so I'll try to structure the message to facilitate navigation.

  Introduction

  Recently, we went from HttpConnection to raw sockets in our application.  It wasn't an easy decision (a lot of extra code had to be written and debugged) - it stemmed from the fact that on different devices HttpConnection behaves very differently and sometimes we would just hang out here for always trying to read something, although enough bytes was available in the buffers of the system (I have seen it with my own eyes; can develop if anyone is interested).  There are other reasons, but this has been the main.

  Previously working solution

  Once we went to the outlets and implemented our own HttpConnection (not me - someone to increase their knowledge in networks of BB did this), our problems have disappeared. In order to reduce the chance of getting stuck forever, we check InputStream.available () of the socket and, if there is always a thread. Sleep() 0, for some small interval (makes me cringe, but well, the user makes a call blocking!) then read just one byte (hoping that there might be something).  It worked for all trackball/touchcpad devices and all kinds of connections (SDM is a separate issue, but we managed)...

  New problem

  ... until we have tested the Storm (5.0 Storm1 and Storm2 - both 5.0 behaved similarly) with all, but connections WiFi disabled.  We have connected WiFi router to the company (I then repeated the test at home with my wireless router and got the same results).  BB browser worked fine.  However, our code began fails on our internal waiting time.  When I connected the phone to the debugger and set up breakpoints, I quickly discovered that InputStream.available () always zero returns! I'm not kidding!

  Our code was constantly diverted waiting, waiting, reading another byte, read a byte...  Even when I changed the way that we on the download time was exceptionally slow (as in "unbearable").

  Worse still - when I tried to wait before making the first longer interval (100ms) read, followed by reading the characters one by one without waiting, the phone started rebooting randomly!

  Request

  Someone has seen something similar?  If so, what was your approach?  I won't sit idly while waiting the answers here - I have a few ideas to try-, but if anyone has been there, it would be nice if you can just push me in the right direction.

  Thanks in advance,

  Arkady.

  Other people have had problems with available().  I'm surprised that you managed to get that you have to be honest, I thought he always returned 0.

  We make socket connections, and always the transmission with a header field that contains prefix length.  So read on the Blackberry is basically

  (a) header to read

  (b) reading of data

  (c) to process the data

  (d) proceed to (a).

  Another user and I had problems recently with http and OS 5.0 using WiFi connections - circuit up to and/or time out when reading the response.  This is the thread

  http://supportforums.BlackBerry.com/T5/Java-development/network-IO-hang-on-OS5/m-p/541487

  I would recommend you change your implementation of socket and detection of data along these kinds of lines, in other words, how data should be read and set up some kind of detection/stall.

  Does make sense?

• How to connect through the connection Socket BIS?

  Hi all, I am trying to connect to Socket BIS. I'm able to establish BIS my service provider Http connection. I downloaded a chat application that checks the types of networks supported by my device/package that has the following list:

  (1) BIS-Http: OK

  (2) BIS-SOCKET: OK

  (3) BES-HTTP: NA

  BES-SOCKET 4): NA

  (5) TCP-HTTP: BAD DNS

  (SOCKET TCP-6): EXPIRED

  I know direct TCP is not supported by my ISP. So I would use BIS-Socket connection. Can anypne please help me reach this type of connectivity? Help, please. Thanks in advance.

  as a member of the alliance, you can apply to BIS-B access with an application. you get your own connection key that you can use to create connections of bis - b.

• Win7 client TCP send RST/ACK

  Win-7 TCP sends [RST/ACK] after ~ 90 sec of traffic all the time. Reproducible 100% on several PC Win - 7.

  Same TCP App on Win - XP works fine.  Socket TCP in both cases connected to one machine Linux Ubuntu.

  Any suggestions how debug layer TCP?

  At soon kes

  Hi kestasj,

  You can find the information in this document useful to determine if raw sockets are supported.

  If additional assistance is needed with the TCP app, post your question in the Peer-to-Peer Networking for Windows Desktop Forum.

• Control packets on the Socket API

  This sounds like a strange question.
  
  I have an application that connects to a banking service ISO using Java Sockets, TCP/IP. The application is ready, but we have had delays in receiving messages. The Bank says they must receive each message in a single TCP/IP packet. Now who doesn't make sense for me because I can't control how TCP/IP sends out packets through the network. In the Socket API I see not all methods to control this with the exception of TcpDelay. So is just a question, there a way to control how packets are sent to the network?
  
  Kind regards
  
  Nestor Boscan

  No, you can't control with the socket API like everything which is abstracted away (thank God!). IMO the requirement itself seems counterproductive to limit and at least error prone if you ask me.

  Maybe the NIO package provides more precise control, but I don't remember having read about it. If anything I would look into the NIO of Java 7 features.

• Tuxedo client implementation

  We have a banking application on Tuxedo with 6000 services advertised through server of the MSSS.

  Our customers access through them through plain/sockets, TCP, without workstation components.

  To do this, we have developed a multithreaded bridge that accepts client connections and calls for theses services.

  the answer back into this Jack.

  My question is what would be the best way to call via a client native Tux Tuxedo services, considering that it could be thousands

  customers connected at the same time.

  If call us via tpcall theses services, we would have to have me 1000 active threads in this bridge and 1000 IPC queue, so it doesn't seem a good idea.

  We would like to have a configuration style wire services and the other thread reading replys, but we have not found a way to do.

  
  

  Thanks in advance.

  Hi Dani,

  The /WS way works, it's that a /WS client connects to a listener of WSL or workstation.  The listener then hands the connection to one of the many managers WSH or workstation that continue to process applications for the client to run.  A single WSL can support several WSH process and each process WSH can manage many clients.  The WSH accepts requests from the network and immediately makes an asynchronous call to the service requested by the remote client.  So to answer your question, if there are 100 concurrent requests, they are queued on the queue or queues associated with the requested service.  So if you have a single MSSS, then all 100 applications would be enrolled in the defined MSSS.

  In addition, please note that it is recommended that a set of MSSS have a fairly limited number of servers manage, as all the inactive servers throughout the queue will be awakened to try to process a request.  So if a lot of servers in the defined queue are inactive, they'll all be awakened and one of them will actually process the request.  The rest hangs again waiting for a message.  So under a lighter load, a lot of process context switches may be incurred.  That said, if the load is light, it cannot be important.  Also, it is often a good idea to have several sets of MSSS manages a set of services to provide more capacity in the queues.

  We have customers with 50,000 or more customers using /WS without problem, so I'm sure /WS can manage your number of clients.

  Kind regards

• Defective VMotion

  Hello

  VMotion fails on some VMs.

  Nothing is attached with virtual machines.

  my group is a mixture of 5.5 / 4.1, but all nodes have the same processor. I am in the process of upgrading of nodes to 5.5...

  Any help

  Are you facing this problem after the 5.5U3? I have a the same problem and the workaround below worked for me.

  1. SSH into the ESXi host

  2. navigate to the directory where the virtual machine is running.

  3. create the folder in the virtual machine directory called BAK - UP

  4 move the swap file (vmname.vswap) to the BAK - UP directory, ignore the vswap named vmx-vswap.

  5. the virtual machine to a different host VMotion.

  The pop3 Checker will not work with apop.  Apop Protocol requires that we send a MD5 hash with the user name.  We can, adding this ability.  In the meantime, you can simply use the Socket TCP Checker to make sure that the port is up and listening.

• vCenter session - find origin of connection

  I have a user who cannot tell me what is logging into vCenter with his credentials.  The account will be idle for several hours.  If I kill the session, it immediately.  How can I find something more identifiable as an IP of origin of the session?  I tried http://nickapedia.com/2010/02/15/vsphere-mini-monitor-now-with-more-cowbell/ on my Win 7 x 64 desktop, but it crashes in various ways when you try to connect to my vCenter.  I know there are scripts PowerCLI to kill any idle sessions, but this 'service' will record everything right back in immediately.  Thank you.

  It is something that you can easily find using vCenter vpxd.logs. You will need to know the session key which you can query the API or use the MOB vCenter under sessionManager object. You must also change your vCenter _tempoairly_ to verbose logging, if it isn't already, by defaul in that the output of logging is configured as 'info' that only goes into detail on real customers officers which is where you will identify the IP address where it connects.

  Once you are ready, turn on detailed logging and put an end to the existing connection. Wait until it reconnects, then take the session key, in this way, you don't have to search through all your vpxd.logs you are looking for the actual connection. Search the main vpxd newspaper and you should see something of the following:

  [2010-12-21 19:27:33.115 01456 info "Libs"] [ADS] Primp account found, but not local
  [2010-12-21 19:27:33.115 01456 info "App"] User authentication error 1326. \primp.
  [2010-12-21 19:27:33.131 01456 info "App"] [Auth]: user PRIMP-IND\primp
  [2010-12-21 19:27:33.131 01456 verbose "App"] [VpxdUser] Registration session with cnxId = 49C1F429-8403-4D0D-B319-7C79C2708FF1
  [2010-12-21 19:27:33.131 01456 verbose "PropertyProvider"] RecordOp ADD: sessionList ['3B655744-E886-41AE-89AC-DFF691901A1B'], SessionManager

  You should see the user name and specifically the sessionList which is your session key. From there, you will key out of the 3rd column and in my example it's "01456" which corresponds to the actual number of thread. You will use this to identify all of the entries in your session and find all the entries, you should see something of what follows not too far from the details of the session, which should look like this:

  [2010-12-21 19:27:36.053 01456 verbose "ProxySvc Req70068"] New local SSL client (TCPStreamWin32 (socket = TCP (fd = 3592) = 172.30.0.60:443, even = 172.30.0.218:53893)
  ))

  It's the real demand and you will see 'local' that must be the IP address of your vCenter server and the 'peers' who is the real customer. In my example, I faked it by logging into the my local office CROWD and this is the IP address of my system.

  If you transfer your vpxd-journal of a Linux host, you can do something of what follows to save time searching using Windows you just define two variables VPX_LOG that is the log file itself and SESSION_ID which is the session key

  VPX_LOG is vpxd - 198.log.; SESSION_ID = 3B655744-E886-41AE-89AC-DFF691901A1B; $grep (grep "${SESSION_ID}" $VPX_LOG | awk '{print $3}') $VPX_LOG | grep counterpart

  This should hopefully help you identify the culprit

• vCenter 4.1 upgrade perf graphic strangeness, vmhba, personalized calendar

  Late last night, that I upgraded from vCenter 4.0 to 4.1.  My hosts are 3.5 130756 (I know, old, vc, update is first before going to bed and breakfast of course)

  So now my perf cards Act strangely.  To start my disk performance graphics do not show the vmhba name, it's just a column blank.  Oh, there is a separation of color and the number of entries is OK, just no names to associate.  It's the same as I watch a host or watch a virtual machine.

  The other thing strange is that when I go in a custom time period and let set 1 hour when the graph rises, the last time the first 5 minutes are not displayed and the last 10 minutes do it either.  Now, when the graph starts on the left side it starts at a value such as 15%, or whatever.  But for the last 10 minutes, just before it stops, all values to zero.

  I think what may happened has something weird on the process I used.  I did the upgrade like me who has full on the server SQL - but rights once the upgrade was done, I went from the user for the service account that was used previously.  It was used before the upgrade without problem.  When I installed first vc4 I did all the steps as service the first time - the DBA account had granted the necessary rights for the service account to create everything but then stripped these rights down there for just the db_reader and writer roles. I went from back and gave him db_owner just to cover it all.

  This could be something crazy to the fact I'm not on vSphere 4.x yet?  It would be unfortunate if this is the case, but in this case I can live with that for this short period of time before I update the hosts.

  The only errors/warnings I get in the vpxd.log are:

  SSLStreamImpl::DoServerHandshake (000000000d687f40) SSL_accept failed. Dumping error SSL queue:

  error: 14094416:SSL routines: SSL3_READ_BYTES:sslv3 unknown alert certificate

  SSL handshake failed to flow TCPStreamWin32 (socket = TCP(fd=3880) local = 10.1.21.49:443, peer = 10.1.21.49:52611), error = Exception of SSL: error: 14094416:SSL routines: SSL3_READ_BYTES:sslv3 unknown alert certificate

  Everything else is a task to start host synchronization task end etc - of the normal stuff.

  I have the same problem, here is the response from VMware:

  The problem with the loss of some data of performance in vc 4.1 is a known issue.

  At present, there is no date for a solution, so if the customer is strongly

  According to these statistics, it should consider returning to his previous vc

  installation.

  Is the bug number: PR599953
