• How to create the TCP non-blocking server?

  Hello

  I would like to have a TCP server at my request.  It will go about their business as usual, but in the background a TCP server sits waiting for a client connection.  If such a link exists, the normal code will send stuff on this topic otherwise it will just not send.  Currently, I do not see how to stop this blocking while it waits for a client (block waiting on TCP listener).  I looked at the example of client/server TCP, but it remains blocked in the same way.

  I would like advice on how I'm framing such a request.  I also want to do the same on the client side.  Go about business as usual and if a connection can be established at a time given, then send stuff on that connection otherwise just not worth it.

  Concerning

  Ashley

  LabVIEW parallel code usually runs in parallel. This is true even a wait - if inside a loop, you wait 100ms and other code in parallel, it is not delay execution of other code, rather he runs forward and the other code at the same time. When both have completed, the loop can proceed to the next iteration. So yes, if you have a loop with a 1000ms wait and another with an expectation of 100 ms and waits take longer to execute any parallel code in loops, then the loop of 100ms will last about 10 times as many times as the loop with the 1000ms wait.

  I recommend that you put the waiting on the listener in a separate loop and also have another parallel loop that manages the communication when the connection is established. You can then use a timeout (forever) of-1 on waiting on the listener, and this loop will be almost never run or use resources except what is first of all establish a connection. To kill this loop, close the listener somewhere which depends on waiting on execution of the listener. When a new connection is established, put the link in a queue, where the communications loop can pick it up.

• Flash as2 cross subject to access the SWF from another server domain

  I have question cross-domain, how do I access the .swf from another swf file without using System.Security.allowDomain() in the swf file, which we are called.

  I use 2 domains and I have 2 files swf is a.com (a.swf) and another is of bcom (b.swf) I want to access the file the a.swf b.swf frames, if I use the system.Security.allowDomain() in b.swf file I can access executives. But without using this way I can access the file from another domain.

  Because I have a risk to change the file b.swf so I vant to go without changing the file b.swf is any other wey to access frames of the file the file a.swf b.swf. Please someone help me solve this problem.

  use a local executable (such as php) to load the b.swf and send it back to a.swf.  for example:

  loadSWF.php:

  <>

  $fh = fopen ("www.b.com/b.swf", "r");

  Header ("Content-type: application/x-shockwave-flash");

  fpassthru ($FH);

  ?>

  a.fla:

  var target_mc:MovieClip=this.createEmptyMovieClip("target_mc",this.getNextHighestDepth());

  target_mc.loadMovie ("loadSWF.php");

• Impersonate user without privilege preferred to access the registry on Windows Server 2008 key/value.

  Hello

  I'm trying to impersonate another Administrators\ [an other domian user] to do some access to the registry key/value with an Administrators\ [my domain user].

  Failed with some registry access denied.

  The code is quite format.

  1. the user to logon: LogonUser (username, domain, password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, Ref token)! = 0)

  2 DuplicateToken: DuplicateToken (token, SecurityImpersonation, ref tokenDuplicate)

  3 impersonate another user:
  m_ImpersonatedUser = new WindowsIdentity (tokenDuplicate);

  using (m_ImpersonationContext = m_ImpersonatedUser.Impersonate ())

  {

  access to the registry key.

  ...
  }

  This works on Windows7 and some windows server 2008, if the new WindowsIdentity.AuthenticationType is "Kerberos", then it works, but if it's the "negotiation", it will fail.

  Can someone tell how to force the AuthenticationType to be "Kerberos"?

  Thank you.

• Cannot access the web configuration utility - server wrote: level_15_access

  I've been using a Dlink router and wasn't getting any beach on my network, so I tried to configure my router linksys wrt150-n v1.1. I pressed the button reset for 20 seconds, then unplugged my modem (cable) and the router, then plugged in. When I open a browser window and type http://198.162.1.1, instead of open the configuration page, I get a message saying "the http://198.162.1.1:80 server requires a user name and password. "The server said: level_15_access.

  I left the empty user name and used the password default admin, and who does nothing.

  Tried to reset the router on 4 or 5 times without success. Any ideas on what I forget? I did not initially provided with the router Router installation CD, and it is not a downloadable file - I should be able to and have in the past been able to use the default IP address and the admin PW.

  Thank you!

• How to access a server based on the TCP/IP protocol port?

  Hi all

  Is it possible to access a server through a specific port via TCP/IP?

  We have a step of database server in our network that supports the TCP/IP access. My boss asks if it is possible to get some simple data via blackberry?

  The thing is that blackberry device is not in the network, how can we put a bb device in our intranet? Via enterprise server?

  Alternatively, if we can put the server on the internet, can the blackberry device access via TCP/IP?

  Thank you

  Jerry

  If you use wifi BB can access local servers. using direct tcp: nope.

  You can use a bes express (which is free) If you're afraid of costs, still takes time to install/configure etc of course, otherwise you can only use your product if your BB is in the local WiFi network.

• Not able to access the PV which are deployed in the RT using the EPICS IO Server

  Hi, we have NIPXIe 8133 and 1 windows vista (32-bit) PC and I installed LabVIEW 2012 (32 bit) and the required modules. I also have another PC (6.3 Santiago RHEL) based on RedHat Linux and all 3 PCs are connected to the same network. I want to develop an application in which I want to deploy some variables of process in RT and want to access this PVs in Red Hat Linux PC. In order to develop this application, I do RT as a server of EPICS and Red Hat Linux PC as a Client of EPICS. I have deployed some variables of process using Server EPICS in RT now I want to access the value of the PVs in Red hat Linux PC and in this EPIC PC base is already installed but I am not able access PVs that are deployed in RT if you please help me solve this problem. Best regards, Ishan

  I have not assigned by default in one of my system and bridge that was the only problem in my system. Once I have given Defaullt bridge in all systems, I can access all of the HP that are deployed in the RT other 2 machines connected in network.

  I've set up another configuration of TCP/IP, but it does not connect. I need to access the 3 different machine networks. Any ideas?

  original title: alternate tcp/ip

  If by "alternate TCP/IP configuration" you mean the settings on this screen--> http://tinyurl.com/42kbqqz, then, to quote Inigo Montoya, "you keep using that Word. I don't think it means what you think it means. »

  The 'alternative' configuration settings tab, if you select "IP address private auto" (APIPA) or "specified user" is only used IF "obtain an IP address automatically" is set on the tab 'General' (http://tinyurl.com/8p9hn) AND the adapter cannot get an IP from a DHCP server.

  Most cable networks use a DHCP server to automatically assign IP addresses.  In this case, just plug your Ethernet cable and you're automatically configured and connected.

  If the problem is that your network requires a static IP address (that is, they use a DHCP server to automatically assign IP addresses), you will need a third-party network settings manager.  If you have an IBM (Lenovo) ThinkPad, you can use "Dial-up connections." IBM Otherwise, see this Google search (I have no experience with any of the applications shown, so I can't comment about them): http://www.google.com/#sclient=psy&hl=en&source=hp&q=network+configuration+switcher&pbx=1&oq=network+configuration+switcher&aq=f&aqi=g-v5&aql=&gs_sm=e&gs_upl=23l1333l1l1599l12l8l0l0l0l5l278l1344l0.7.1l8l0&bav=on.2,or.r_gc.r_pw.&fp=74e371c96a48f4b&biw=1024&bih=649

• Cannot access the Web server in the DMZ from the inside using IP global

  Hi all

  I hope it's a very simple question.

  I'm running a PIX 515 firewall v6.3. I set up a Web server in my DMZ and use static NAT for re-branded it overall static IP address. Access from the outside of the demilitarized zone works remarkably well. I can access inside the interface Web site using the internal IP, but I can't access it from inside interface using the global IP are entrusted to him.

  Is there a particular reason why this would not be allowed? My feeling was that the request would be forwarded via the external interface (as it is a global IP address) and then be bounced back by my sense of the ISP the request would come to the new external interface (as the static NAT is applied to the external interface).

  However if I try and access the global IP from my inside interface, then the browser can not find the server.

  can someone explain why this is so? Any information would be appreciated.

  see you soon,

  Wayne

  Code v6 pix or less don't let you have traffic "back" or return flow via the same interface on which it was sent. Having also your bounce back off of an external server traffic is never a good idea, because you won't be able to distinguish which and rogue attacks by spoofing someone outside your network.

  Since you are using pix 6.3 code, you may be able to outside the NAT. Add this static to your config:

  static (dmz, upside down) 203.169.113.110 10.1.1.27 netmask 255.255.255.255 0 0

  You may need to run a clear xlate after adding the new static statement. Note that the interfaces: it's demilitarized zone, inside inside, dmz.

  I would like to know if it works.

• Can not access the site Web of John Lewis, get message server unexpectedly dropped the connection all the time

  Use the iMac with El Capitan 10.11.1 & Safari 9.0.1

  During the last week, I was unable to access the site Web of John Lewis and the message "Safari cannot open page www.johnlewis.com because the server dropped the connection unexpectedly. Sometimes this happens when the server is busy. Wait a few minutes and then try again"I retry but get the same message all the time. Can access all other sites ok.

  I emptied the cache, deleted the cookies and history. Enter the name of the site in its entirety is not helped either.

  Unable to access the Web by John Lewis site with my iPad either.

  Help!

  Try restarting/resetting the router.

  Try a reboot.

  Make a backup using Time Machine or a cloning program, to ensure that data files can be recovered. Two backups are better than one.

  Try to set up another admin user account to see if the same problem persists. If back to my Mac is enabled in system preferences, the guest account will not work. The intention is to see if it is specific to an account or a system wide problem. This account can be deleted later.

  Isolate a problem by using a different user account

  If the problem is still there, try to start safe mode using your usual account.  Disconnect all devices except those necessary for the test. Shut down the computer and then put it up after a 10 second wait. Immediately after hearing the startup chime, hold down the SHIFT key and continue to hold it until the gray Apple icon and a progress bar appear. Startup is considerably slower than normal. This will reset some caches, forces a check for directory and disables all start-up and connection, among other things. When you restart normally, the initial restart may be slower than normal. If the system is operating normally, there may be 3rd party applications that pose a problem. Try to delete/disable the third-party applications after a reboot using the UN-Installer. For each disable/remove, you need to restart if you do them all at once.

  Safe mode - on El Capitan

  Start Mode without failure-El Capitan.

• to access the data of hyperteminal using labview

  Do not use hyperterminal. Use the series of VISA. Look at the examples that come with LabVIEW.
