• connections of RAW socket to the server inside the corporate network

  Hello!

  I have not found any documentation anywhere elsewhere I hope someone can help out me.

  o know for ftp/http there are a proxy that is used in the scope of work to access the servers inside the corporate network.

  But what is the best practice for an application installed on the perimeter of work to establish a raw socket connection to access network resources other than http/ftp behind my corporate firewall? so I want something like

  sock int = socket (AF_INET, SOCK_STREAM, 0);

  Connect (...) //using a host/ip within my company and port 1234

  Write (...)

  Close (sock)

  is this possible?

  and second: will it work if I use QTCPSocket?

  Hello.

  Yes, there is a recommended approach to do this for the current version of BES.  A HTTP proxy is used to connect to both corporate and external networks internal when in the scope of work.  To connect to a particular host and port, you HTTP CONNECT request to the proxy, and then once the connection is established, you have a connection with the remote server socket.  I wrote a sample application that covers the QTcpSocket / QSslSocket, BSD sockets, OpenSSL taken and connections of curvature (the species is supposed to be transparent, but there has been problems reported with some built OS).

  I'll clean up this sample application and submit for review before it is posted on GitHub.  If your need is urgent, I could share a few code snippets to help you to implement the solution for your specific use case.

• RAW Socket SOCK_RAW denied in Windows 7, I am administrator already

  Hello

  I'm porting a library of sockets of * NIX for Windows and everything works fine, except the raw sockets which, during the socket() call always returns

  WSAEACCES (10013) - permission denied

  As far as I know, it requires administrator privileges, but my (only) account has administrator privileges (Administrator account). I use Windows 7 x 64 and VC ++ Express 10.

  I found a post here that indicated to create a registry entry

  HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Afd\Parameters\ DisableRawSecurity
  DWORD: 1

  and tried, but after reboot my continuous application fail with return code 10013 after calling socket().

  How can I enable the use of raw sockets? They should work, because it is documented on MSDN.

  Thank you

• 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?

• Power (WT3000) on Ethernet Analyzer

  I am currently looking to 2014 SignalExpress allows to acquire a power Analyzer Yokogawa WT3000 data. I found the IVI drivers for this instrument here, but it includes only the pilots of series and GPIB. I'm trying to communicate by Ethernet.

  I could add the instrument to MAX (network devices-> create new VISA TCP/IP resource-> manual entry of Raw Socket with the IP and port 10001), and the device can be seen. However, when I try to acquire data in SignalExpress (acquire signals-IVI > acquire-> IVI brought acquire-> Create new sessions with device driver TCP MAX and niScope) I get the following error:

  "Configuration error: information about the inadequate location or the device or resource is not present in the system."

  Any thoughts? I am fairly new SignalExpress and have never used the front IVI drivers, so it is possible, that I'm missing something. Or maybe it's just the fact that only GPIB and series are supported? Is it possible for me to convert the pilot as well as Ethernet is supported?

  For anyone who is struggling with this problem, I found a temporary solution. SignalExpress supports the IVI (and non-plug-and-play drivers) drivers only because I wrote a LabVIEW VI that uses the provided Yokogowa plug-and-play driver to query the WT3000 data and then publishes these data to shared variables. SignalExpress can then read these shared variables instead of directly read data from the instrument.

• Fluke 8845 A does not meet the LAN port

  I downloaded Fluke 884 X installed and installed driver.  The 8845A is connected to an internal LAN network.   Manually set the IP address, subform on the instrument.  Used the Measurement & Automation Explorer to search for the device.  Autodiscover does not work, but a manual entry of the raw socket.  Could validate the connection of the device.

  However, when I place a simple VI - say to run, well, whatever it is - initialize, system, etc., it seems I get a time-out error.  (I'm tired of sitting in the corner).  In any case, is someone tried the LAN connection?  Since I am new to LabView, maybe I missed something?

  Thanks in advance.

  I don't think that the DMM 8845/8846 is compliant VXI - 11, while the instrument of Agilent is compatible, you can check if the moat has an update of the firmware.

• Timeout with instrument ethernet error

  Hello

  I'm having a hard time communicating with a Tektronix DMM4050 via Ethernet.

  I added the device in MAX by adding manual entry of Raw Socket (automatic and manual input of the instrument of LAN didn't work).

  What works:

  I have provided the stop character activate in settings/o, I can send the * IDN? \n query to the instrument, which translates into a beautiful "TEKTRONIX, DMM4050, 2199203, 02/08/10 - 11:53\r\n" string.

  What does not work:

  The simple code below

  

  Translates a VISA: (Hex 0xBFFF0015) timeout expired before the operation is complete. error.

  Any suggestions would be greatly appreciated

  Boris

  What display format you use for your string constant?  Set it on ' display Codes «--------»»  Then you should have "* IDN? \n ».  I think if you switch the display will read "* IDN? \\n"who did not finish the command for the application and therefore, it does not recognize the command.

  Why not just use the normal functions of TCP/IP? I'm not even sure that you can talk to a non-VXI-11 device with VISA. You have many examples of TCP/IP, choose a.

  VISA TCP will work with any generic TCP device.

  2. setting of the session to follow the instructions (as per joint, LAB_WM827.pdf)

     Set the IP address: 137.57.96.8 (this IP address is successful to be ping by PC and this address is of course belong to the 104Xi WaveRunner oscilloscope)
  Set the port number: 1861

  3. then, there will be a new resource under "resources VISA TCP/IP". Select this option and 'VISA Open Session'. A dialog box will be retractable to the communication of the instrument.

  4. go to the tab "viSetAttribute", the value VI_ATTR_TCP_KEEPALIVE to VI_TRUE, VI_ATTR_TMO_VALUE the value of 15000.

  "After all this, I send '* IDN? \n"(dans l'onglet viWrite ), it returns the value 0 (which means no error occur) and return 6 counts. " So I try to read a buffer (in the viRead tab), but it send me error timeout (VI_ERROR_TMO). After that, I erase the buffer in viClear. Then, I repeat same steps, this time he (viRead) return me connection lost error (VI_ERROR_CONN_LOST).

  This situation is repeated every time that I reopen it new session. In the meantime, I also doubt that the viWrite did send the command to the oscilloscope or not. The oscilloscope was no response after that I have send "ASET" (WaveRunner 104Xi order for autosetup oscilloscope) through the viWrite tab.

  I am out of ideas now.

  What's my configuration OR-MAX problem? or hardware problem? or a server problem?

  Please advice... need help badly.

  Thanks in advance.

  Hi wcsoh,

  Alan and LeCroy Support here...

  Use the type of connection (LXI).  The problem is that when you use the connection TCP/IP (ACIP) type, you cannot configure the WaveRunner 104MXi as a resource of VISA's TCP/IP in MAX.   Note that MAX is not 'hip' to recognize any instrument type TCPIP, including extended via ACIP LeCroy.  To use LXI, go to utilities > utility configuration... and then to the 'Remote' tab, where you will find the button on the left side of the screen of config to use 'LXI '.  If you don't see this button, you will probably need to update your firmware.

  With the type of connection (LXI), you can automatically find the scope through MAX, enter this amount as a VISA TCP/IP resource and configure an alias as well...  You can also point your web browser to the IP address of the bezel, and you will see a status page with information, including the name VISA always useful resource to use when you configure the scope in MAX.  (Note, however, there is no need to use MAX at all when the connections of VISA to LeCroy oscillloscopes!)

  Here is a link to an application note written by me which deals with the LXI interface, including information about the configuration of MAX to show scope: http://www.lecroy.com/tm/library/AppNotes/LXI/LXI_Interfacing_AppNote.pdf

  Do not hesitate to contact me for any question!

• How to implement an ethernet without TCP or UDP communication?

  I know there are blocks to transmit/receive data via the Protocol TCP or UDP in Labview,.

  but I need to pass data between one compactRIO and another device that is not NEITHER device.

  They communicate via Ethernet, BUT this unit has its own Protocol (TCP or UDP),

  So just me LabVIEW to transmit raw data via Ethernet without any header (for example TCP or UDP, etc.) because I will deal with it by myself,.

  What is the best work in Labview can I use for this?

  Thank you!!

  None! You must call directly into the OS API Jack for a raw configuration network socket, and then use read() and write() on it. Note that raw sockets are all modern operating systems preferred Office of resources which can only be opened by a process granting access rights. On Windows, it is reserved for processes with administrator rights. In Linux, there are just special access that must be given to a process for this.

  Under cRIO this right of access is probably not a problem, but you may encounter problems that raw sockets are only partially taken in charge there.

• Why do I get a warning "stop character has been read" with VISA read and TCPIP?

  I use VISA readings with raw sockets TCPIP without problem with NI-VISA 3.0.1 but when I moved to NI-VISA 4.4 I was getting timeout errors.   Time-out errors disappeared when I put the stop character allow the property (which seemed to be default in NI-VISA 3.0.1) but now I get a warning indicating that the "stop character was read.

  Can I turn off this warning?   Can I put the ending character activate by default?   How can I get rid of this annoying warning?

  Hey, Dagwood,.

  Unfortunately, there is not a way to globally change the attribute VI_ATTR_TERMCHAR_EN to VI_TRUE.  Talked with R & D ability to use registers and they say that it is not accessible through that.  To answer why this change was made so the developer who made the switch isn't around more I can not find his reasoning to explain.  The best to you in your code would be during initialization, use the node property VISA to make the change and until the closure of this VISA resource, this change will be the value that you assign the value.  I'm sorry, we cannot provide any other solution for these problems.  Also, if you feel that it is a heavy load on your programming practice you can certainly submit a product idea for the ability to change the overall values for default attributes VISA.

  Thank you

• Try to connect to the power supply via the IP address

  Hello

  I am trying to connect to a power supply of Sorensen XEL60 - 1.5 P. I have its IP address and port number, but I'm stuck on an error 63, cited at the end I tried the advice in this forum and online without success, including:

  Disabling firewall

  * the ip address ping command

  * Tools > options > VI Server

  http://digital.NI.com/public.nsf/allkb/6ccced1045c479d286256a3a00655123

  Open all the ports LV wants

  Nothing improves the situation. What I will try?

  Thank you very much

  

  Error 63:

  LabVIEW: Serial Port receive buffer overflow.
  =========================
  LabVIEW: The network connection was refused by the server. For TCP/IP, make sure that the server is running and listening on the port you want to use. Firewalls can also cause a server to refuse a connection. To VI Server, make sure that you have enabled the server from VI tools > Options > VI Server.

  No reason to be a donkey to people asking for advice. I tried UKRAINE by the boards, conscientiously the profit and loss account.

  I can actually get the power supply to operate on the VISA. It needed fixed two bugs, in the case where others are interested:

  * Setting VI_ATTR-TERMCHAR_EN to VI_TRUE

  * Creation of the resource VISA under the 'manual entry of the raw socket"rather than one of the other two. This is necessary because I'm trying to communicate via a specified port.

  So I'm fine now, I just can't pass strings directly via IP and port that I thought I should. It may be a device-specific problem, but I'm always interested in other thoughts.

  Thank you

• custom action builds without error

  All,

  I am trying to create a custom action where it administers all events/alarms to another server for processing.  First, create a rule that implements the custom action, where the action is supposed to be triggered on every event/alarm.  The custom action will then take the event and move on to another server via a raw socket and made a simple handshake with sha1 base 64.  I welcomed for groovy and java during the construction of the custom action and it builds just fine without error.  However, when I install cartridge and turn on the rule, the server receives nothing and I do not see the log entries.

  Build.XML I had to ad a taskdef to groovyc and add a different path to the jar file.  I enclose my Ant and source files.  Any help to find where I'm wrong well would be apprieciated.  I think that the problem is around the keyword implents and how I created that, but I'm not sure.

  Thanks for any help!

  Can you please post screenshots of this rule?

  There is a rule of Foglight making snmp with impatience that sends snmp traps to another http://en.community.dell.com/techcenter/performance-monitoring/foglight-administrators/w/admins-wiki/5567.event-driven-rules-snmp-forwardserver.  I don't know how your rule is constructed, but the simplest can be copy that snmp before rule, rename it simply to put your action and see if it works. At least the starting point will be a tested rule that works in several sites.
