Bluetooth client server VIs

Hii all,
I am developing bluetooth application using labview bluetooth vis.
I have my bluetooth enabled PC using bluetooth dongle. Now I want to send some data, say a string Hello from my PC to a Nokia mobile 2700 series. Is it possible?
If Yes , in such case
1) What will be my client and what will be the server? as I intend to use client/server VIs provided in labview example finder . What is the exact difference between client and server in bluetooth domain?
2) Can I run both the VIs on same PC?
3) Simple Client VI uses "Bluetooth Open connection" VI ...so which address do I need to provide there ..is it PC's bluetooth address or Nokia's bluetooth address?
4) Simple Server VI uses "Create Listener" VI who asks for UUID...which UUID needs to be provided..is it PC's or Mobile's bluetooth?
Please do the needful.
Best Regards

In looking at some of the documentation, it appears that the driver required for using Bluetooth with LabVIEW is very specific. You need to have the Microsoft Bluetooth driver - not the driver that comes with the Bluetooth device. Also try lowing your security settings, or removing them.

Hi i used the simple bluetooth client server example in labview 7.1. Iam getting an error saying your system does not support the network operation. I have following doubts also.
1. Should i pair the device before running the labview.
2. Should i enable the file transfer wizard in the software given with the bluetooth adapter.
Please help
Thank you

Can Simple Data Client/Server VIs communicate between computers?

I am having trouble using the Simple Data Client VI / Simple Data Server VI to communicate between computers? Can these VIs do this ..or do they simply communicate between each other on a single computer? TIA.

NO it can be used between two computers. You have to replace the localhist string with the IP address of the computer running the server and make sure that the server computer is allowing external connections on the specified port.

Bluetooth Read VI error - simple bluetooth client/server

Hello,
I've been able to run both the simple and advanced bluetooth LV examples, but I can't make the simple code below to work between my laptop and my PDA. Connection is established, but the Bluetooth Read VI returns an empty string.
Thanks in advance for any ideas.

Problem using the File Dialog Box in a Client/Server application

I am developping a client-server application using Labview 5.1 . The application on the server acquires data from some instruments and saves it on file, while the application on the clients displayes such acquired data. For doing this I call some routines on the server via the "Open Application vi" (remote connection). All goes well except when I open on the server the "File Dialog Box vi" : in this case the application on the clients is blocked (is blocked the execution of the called vi on the server). Only when
the File Dialog Box on the server is closed, the execution of the called vi on the server starts again.
I need to use the File Dialog Box on the server, but I don' t want to stop at the same time
the clients !!
I need help for resolving such problem.
Many thanks in advance !!!

"It seems that the VIs called by the clients are running in the user interface thread.
A call to the file dialog box will call a modal system dialog. So LV can't go on executing VIs in the user interface thread."
Are you sure? I think, that File Dialog, called by LabVIEW File Dialog from Advanced File Functions Palette doesn't blocking any cycles in subVI, which running in UI Thread. Look in my old example (that was prepared for other topic, but may be good for this topic too).
2 linus:
I think, you must a little bit reorganize you application for to do this. You must put your File Dialog into separated cycle. This cycle, of course, will be blocked when File Dialog appear on the screen. But other cy
cle, which responsible for visualization will run continuosly at the same time...

Establish a connection through RF modem's on client & server side & to set up PPP communication for data transfer

hi
can any1 over here help me out in how to establish connection between 2 RF modem's for data transfer , between client & server USing LABVIEW?
I want to establish a connection between 2 PC's through RF modem on client & server side & to set up PPP communication for data transfer.
(I have tried data transfer through RS-232 using TCP/IP whn the 2 PC's are connected over ethernet... which is working.
I also tried connecting loopback cable between 2 PC's COM port & geting data transfer using VIsa configure serial port & other visa functions ... which is working)
can u guide me how to establish connection between 2 RF modem's using LABview?
& how does the data transfer take place between 2 RF modems through RS-232?
is it using TCP/IP?
If you got any links to go abt this issue do send me related links .. or any examples .....
I am currently using Labview version 8.
Waiting in anticipation.. reply ASAP..
thanking you
Regards
Yogan..

Howdy yogan,
Maybe you could clarify a few things for me, and we'll see how we can help ya. TCP/IP protocol occurs through an ethernet connection; RS-232 communication occurs through an RS-232 serial connection, typically through a cable that has a DB9 connector on both ends. Do you mean that the RF modems in question have the option to communicate via RS-232 and/or via TCP/IP ethernet? Specific information like the manufacturer of your RF modems, the model number of your RF modems, and how you connect the modems to the PC would enable us to give you more efficient support.
You can check our Instrument Driver Network (IDNet) to see if a plug-and-play/IVI driver already exists for your RF modem. (You'll need to know its manufacturer and model number.) In the case that you do find an IDNet driver for your modem, you can use this KnowledgeBase article for instructions on how to use the driver.
Another excellent resource to consider is the NI Example Finder. You can access this within LabVIEW by navigating to Help»Find Examples and then searching for serial or TCP/IP examples.

Client/Server between iPhones

Hi all,
I have to develop a networking component for multiplayer games on iPhone. I wondered about the possibility to build a client/server achitecture over bluetooth between two or more iPhones, and if it was possible using CFSocket, CFNetwork classes ? Or are there other useful classes ?
Thank you.

To enable cross release client/server operation you need to add the line
-insecure-backwards-compat
to the ttendaemon.options file located in <tt_install_dir>/info on the system that hosts the datastores that you wish to connect to. For this to take effect you must restart the main daemon so you will need to shutdown all the datastores before doing this!
This is documented in the TimesTen Installation Guide and the Timesten operations Guide.

Various Bluetooth Clients Actives

Hi!
I'm trying develop a Client-Server aplication with bluetooth communication. I need 2 clients connecteds with the server (PC). The question is: My Server stands I client conection in time. How can I connect 2 clients to my server at the same time?
I'm trying RFCOMM protocol. On JSR-82 documentation says:
"The SPP service can accept multiple connections from different clients by calling acceptAndOpen()". I've tried but I got a BluetoothConnectionException: timeout. In fact I nly can conect my second client when first disconnect.
Follows a part of application source code:
boolean listening = true;
boolean firstTime = true;
String cmd = "";
while (true) {
System.err.println("Listening...");
try {
if (listening) {
System.err.println("Waiting incomming conexion 1...");
conn1 = (StreamConnection) server.acceptAndOpen();
/*--------- Client Connected waiting for incoming data --*/
din1 = new DataInputStream(conn.openInputStream());
dout1 = new DataOutputStream(conn.openOutputStream());
System.err.println("First client connected...");
System.err.println("Waiting incomming conexion 2...");
conn2 = (StreamConnection) server.acceptAndOpen();
din2 = new DataInputStream(conn2.openInputStream());
dout2 = new DataOutputStream(conn2.openOutputStream());
System.err.println("Second client connected...");
My server runs on windows XP and my bluetooth driver is bluesoleil 2.3. My dongle-USB is a multilaser AV00018ML.
If anyone have a example with more than one client conection active in time please send me.
Help!!!!
Hugs,
Leydson

Guess that the best way to do this is with wifi then..

Client/Server to Web-Based application Conversion

Hi! Everyone,
I have couple of questions for you guys.
Our Client had recently upgraded Forms 4.5 to 6i to move from Client/Server based application to Web based application.
They are using Forms Server 6i Patch Set 1, OAS 4.0.8.1, Windows NT Service Pack 5 and Oracle 7.3. They are facing the following error every now and then, when they run the forms,
"FRM-92100: Your connection to the server was interrupted. This may be the result of a network error or a failure on the server.You will need to re-establish your session."
Please let me know what might be causing the above error. The only problem i can think about might be Oracle 7.3. If i am right only Oracle 8 and above supports Forms 6i.
Can anyone let me know some tips and/or techniques to upgrade Forms 4.5 to 6i. If there are any important settings/steps which we might have over looked during the upgrade, please list them.
Any kind of help is greatly appreciated.
Thanks,
Jeevan Kallem

Client/server program validation - is it possible?

I've been mulling over this problem for a few days, and am starting to wonder if it's theoretically possible to find a solution. I'm not looking for specific code, this probably won't even be implemented in Java, I'm just wondering if there is a theoretical program model that would work in this situation.
The short version:
Validate the data generated by a client program, without knowing the original data.
The long version:
This is a "profiling" system for a MMOG (Massively Multiplayer Online Game). The MMOG is an internet based client/server graphical program where each client connects to the server and they interact with each other and the virtual world. They pay a monthly fee for access to the game. My program is not affiliated with the MMOG or its makers. I have no connections inside the company and cannot expect any cooperation from them.
The "profiling" system is also a client/server model. The client program runs in the background while the MMOG client is active. It accesses the memory of the MMOG client to retrieve information about the player's character. Then, possibly on request or maybe immediately, it sends the character data to our server.
What I want to validate is that the character data being sent is unmodified and actually comes from the MMOG program.
I can reasonably expect that with mild encryption and some sort of checksum or digest, the vast majority of problems can be avoided. However, I am not sure it's possible to completely secure the system.
I assume that the user has access to and knowledge of the profiler client and the MMOG client, their assembly code, and the ability to modify them or create new programs, leveraging that knowledge. I also assume that the user does not have access to or knowledge of either of the server applications - the MMOG server or mine.
In a worst-case scenario, there are several ways they could circumvent any security I have yet been able to think of. For instance, they could set up a fake MMOG client that had the data they wanted in memory, and let the profiler access that instead of the real thing. Or, they could rewrite the profiler to use the data they wanted and still encrypt it using whatever format I had specified.
I have been considering using some kind of buffer overflow vulnerability or remote execution technique that would allow me to run specific parts of the client program on command, or get information by request, something that could not be anticipated prior to execution and thus could not be faked. But this seems not only insecure for the client but also not quite solid enough, depending on how it was implemented.
Perhaps a series of apparently random validation codes, where the client does not know which one actually is doing the validation, so it must honor them all. Again, this is very conceptual and I'm sure that I'm not explaining them very well. I'm open to ideas.
If I don't come up with anything better, I would consider relying on human error and the fact that the user will not know, at first, the relevance of some of the data being passed between client and server. In this case, I would include some kind of "security handshake" that looks like garbage to the client but actually is validated on the server end. A modified program or data file would result in an invalid handshake, alerting the server (and me) that this client was a potential problem. The client would have no idea anything had gone wrong, because they would not know what data the server was expecting to receive.
I hope I have not confused anyone too much. I know I've confused myself....

Yes, that is the general model for all MMOGs these days - no data that can actually affect the game is safe if loaded from the client's computer. All character and world data is sent from server to client and stored in memory. Any information that is saved to the client's computer is for reference only and not used by the game engine to determine the results of actions/events etc.
My program accesses the MMOG client's memory while the game is running, and takes the character information from there. It does not have direct access to the MMOG server, and does not attempt to modify the data or the memory. Instead, it just encrypts it and sends it to our server, where the information is loaded into a database.
The security issue comes into play because our database is used for ranking purposes, and if someone were to hack my program, they could send invalid data to our servers and affect the rankings unfairly.
I'm just trying to think of a way to prevent that from happening.

I HAVE DOWNLOADED 2 UTILITY LIBRARIES D2KCOMN and D2KWUTIL TO MY COMPUTER. THESE 2 LIBRARIES ARE COPIED TO AN ORACLE FORM. ON THE FORM, THERS IS A BUTTON. IN THE WHEN-BUTTON-PRESSED-TRIGGER, I HAVE CODED
WIN_API_SHELL.WINEXEC('"C:\PROGRAM FILES\MICROSOFT OFFICE\OFFICE\OUTLOOK.EXE"-c IPM.Note/m"'||:email.recipient_name||'&cc='||

ARE FIELDS ON THE ORACLE FORM.
THE NAMES ARE DEFINED BY THE PROGRAMMER.
THE NAMES OF THE FIELDS ARE NOT RESERVED WORDS.
WHEN THE CODE IS EXECUTED, MICROSOFT OUTLOOK IS OPENED AND THE RECIPIENT LINE, COURTESY COPY LINE, SUBJECT LINE
AND BODY OF A NEW MESSAGE ARE PREPOPUTATED WITH THESE FIELDS FROM AN ORACLE FORM.
THIS ROUTINE WORKS FINE ON AN ORACLE6i CLIENT SERVER BUT IT WILL NOT WORK WELL ON AN ORACLE9i CLIENT SERVER.
WHAT DO I NEED TO DO TO CHANGE MY CODE? DO I NEED TO USE NEW UTILITY LIBRARIES? I WOULD SURE LIKE TO KNOW WHAT TO DO.

Oracle9i Forms does not support client server - so you are running in a different environment (even though you may still only be onl two tiers).

VPN Site-to-Site or VPN Client Server with Cisco IP Phone 8941 and 8945

Hi everyone,
I decide to deploy a CUCM (BE6K platform), SX20, and IP Phone 8941/8945 on Head Office and Cisco SX10 and IP Phone 8941/8945 for branch offices (actually 9 branch offices).
The connection will use internet connection for HO and each branch offices.
And the IT guy want to use kind a VPN client server or VPN site-to-site for the connection through internet,
what kind of VPN client server or VPN site-to-site that recommended for this deployment?
and what type of Cisco router that support that kind of VPN (the cheapest one will be great)?
So the SX10 and IP Phone 8941/8945 in branch offices can work properly through internet connection?
please advise
Regards,
Ovindo

Hi Leo,
technically, the ipsec users will not use up any premium license seats, so if you have 10 ipsec users connecting first, the premium seats are still free and so you can then still have 10 phones/anyconnect users connect.
However, the 250 you mention is the global platform limit, so it refers to the sum of premium and non-premium connections. Or in other words, you can have 240 ipsec users and 10 phones, but not 250 ipsec users and 10 phones.
If 250 ipsec users and 10 phones would try to connect, it would be first-in, first-served, e.g. you could have 248 ipsec users and 2 phones connected.
Note: since you have Essentials disabled I'm assuming you are referring to the legacy "Cisco vpnclient" (IKEv1 client) which does not require any license on the ASA. But for the benefit of others reading this thread: if you do have Anyconnect clients (using SSL or IPsec/IKEv2) for which you currently have an Essentials license, then note that the Essentials and Premium license cannot co-exist. So for e.g. 240 Anyconnect users and no phones, you can use Essentials. For 240 Anyconnect users and 10 phones, you need a 250-seat Premium license (and a vpn phone license).

How to delete the workbench client server name in FDM

Hi Gurus
How to delete/change the workbench client server name in FDQM?
regards
Sarilla

OK, I understand now. You are referring to the Load Balance Server Group. Yes, this can be done:
a) Browse to Oracle\Middleware\EPMSystem11R1\Products\FinancialDataQuality\SharedComponents\Config
b) Locate the LoadBalanceServerGroups.xml file
You can delete this file. The next time the workbench is launched it will ask you to set the load balance server group again and will create this file again.

Which keys are used in Client/Server Authentication?

Hi.
I am trying to understand how SunX509 algorithm works in a TLS context. When Server or Client authentication is done, which keys of the keystore are used?
I mean, when you set up your KeyStore instance, it is loaded a whole KeyStore from the filesystem, which has a lot of keys to be used. Are they all tried in order to find the key that authenticates the Client/Server, and when a key that works is found means that Client/Server is authenticated? Or a concrete key with a specific alias is used?
Do you know a doc or something similar where i can see this explanation? I haven't found this matter in JSSE API User's Guide nor in JSSE Javadocs.
Thanks!

The alias that is chosen is arbitrary and depends upon the order in which the aliases are returned via a hashtable enumeration. If you want to make sure you're using a particular aliasn you must write your own key manager, take a look at the X509KeyManager interface with methods such chooseClientAlias(), chooseServerAlias(), ...

Looking for a client/server that supports multiple protocol and delivery

Hi all, I don't know if this the right place to ask my question,here it goes.
I am looking to develop a client-server that supports multiple protocols such as HTTP, HTTPS etc. I am looking for a framework( i don't know if that is correct or I need some kind of web-service (soap etc)) that would manage connection, security etc. I would like to like to devote most of my time in developing business objects with multiple delivery mechanism such as sending serilized java objects, xml message or soap message, or in some case JMS message as well. So I need a client server that can come in via TCP/IP or HTTP or anyother industry standard protocol and I should be able to service him with pub/sub model and also request/response model as well.
I don't know if I had explained what I need, I would like to know what technologies I should be evaluating and which direction I should be heading... Also the server I'm developing should be free of Java constraints if needed...
Also this service is not webbased service as now but if need arises I should have a flexibilty to make them web enabled in future. Also I would like to work with open source webservers or appservers if I need

"i3 was created because wmii, our favorite window manager at the time, didn't provide some features we wanted (multi-monitor done right, for example), had some bugs, didn't progress since quite some time and wasn't easy to hack at all (source code comments/documentation completely lacking). Still, we think the wmii developers and contributors did a great job. Thank you for inspiring us to create i3. "
To change the border of the current client, you can use bn to use the normal border (including window title), bp to use a 1-pixel border (no window title) and bb to make the client borderless. There is also bt which will toggle the different border styles.
Examples:
bindsym Mod1+t bn
bindsym Mod1+y bp
bindsym Mod1+u bb
or put in your config file
new_window bb
