  • SSL certificates: No Client certificate key exhange

    - by user334246
    I am trying to access a WCF web service, that is using two way SSL encryption. When I try to call the service I get a System.ServiceModel.Security.SecurityNegotiationException: Could not establish secure channel for SSL/TLS with authority 'XXX.xx'. --- System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel. I have tried activating wire shark, to see what is sent to and from the server: I see a client hello and a server hello. But there is no client response to the server hello. I was expecting a "Certificate. Client key exchange. Change cipher. Encrypted handshake Message" package, but none is sent. I'm thinking it is a problem with the certificate sent by the server, that somehow my client server does not trusy it. Here is what I have already tried: I have created the certificate, through the proper authority, though I could have made a mistake in the certificate request without knowing it. I have added the two root certificates to: trusted root certificates, trusted publishers and trusted people. I have also added the client certificate to trusted people. My colleague has succeded in establishing connection on a win 2008 server (i'm using a 2003, because it is necessary for some odd reason - don't ask). I can't see any differences in our approach, so i'm a bit lost. Any help would be greatly appreciated.

  • How to access the remote OPC server programatically ?

    - by Shailesh Jaiswal
    I have downloaded & installed the OPCDA.NET client component evaluation & XMLDA.NET client component evaluation. It provides some C# samples for browsing the available OPC Server, connecting to the OPC server, & browsing the available items on the server. I know the programatic way in which we can access the local OPC server. It is provided in the sample C# applications. I have installed the OPC server on another machine ( remote machine ). I have done all the required setting related to the 'dcomcnfg' utility. I can access the remote OPC server from client machine by using the Test Client provided by the OPCDA.NET client component evaluation & XMLDA.NET client component evaluation. But I am unaware of how this can be done programmatically. In the available C# samples I found no such programatic part (coding ) in which we can access the remote OPC server. Can you provide me the code through which I can browse the available remote machines in my network, available OPC server on each machine after selecting the specific machine name, connecting to the OPC server & browsing the available items on the server ? or Can you provide me the any link through which I can resolve the above issue ?

  • WCF - calling back to client (duplex ?)

    - by MüllerDK
    Hi, I have a problem with what solution to choose.. I have a server running having a Service running that can receive orders from a website. To this server several client (remote computers) are connected somehow. I would really like to use WCF for all comunication, but not sure it's possible. I dont wanna configure all client firewall settings in their routers, so the clients would have to connect to the server. But when an order is recieved on the server, it should be transferred to a specific client. One solution could be to have the Client connect using a duplex binding, but it will have to somehow keep the connection alive in order to be able to received data from server... Is this a good way to do this ?? Normally the connection times out and probably for a good reason... Anyone have insight to this problem. Thx alot for any advise :-) Best Regards Søren Müller

  • SQL Compact allow only one WCF Client

    - by Andreas Hoffmann
    Hi, I write a little Chat Application. To save some infos like Username and Password I store the Data in an SQL-Compact 3.5 SP1 Database. Everything working fine, but If another (the same .exe on the same machine) Client want to access the Service. It came an EndpointNotFound exception, from the ServiceReference.Class.Open() at the Second Client. So i remove the CE Data Access Code and I get no Error (with an if (false)) Where is the Problem? I googled for this, but no one seems the same error I get :( SOLUTION I used the wrapper in http://csharponphone.blogspot.com/2007/01/keeping-sqlceconnection-open-and-thread.html for threat safty, and now it works :) Client Code: public test() { var newCompositeType = new Client.ServiceReference1.CompositeType(); newCompositeType.StringValue = "Hallo" + DateTime.Now.ToLongTimeString(); newCompositeType.Save = (Console.ReadKey().Key == ConsoleKey.J); ServiceReference1.Service1Client sc = new Client.ServiceReference1.Service1Client(); sc.Open(); Console.WriteLine("Save " + newCompositeType.StringValue); sc.GetDataUsingDataContract(newCompositeType); sc.Close(); } Server Code public CompositeType GetDataUsingDataContract(CompositeType composite) { if (composite.Save) { SqlCeConnection con = new SqlCeConnection(Properties.Settings.Default.Con); con.Open(); var com = con.CreateCommand(); com.CommandText = "SELECT * FROM TEST"; SqlCeResultSet result = com.ExecuteResultSet(ResultSetOptions.Scrollable | ResultSetOptions.Updatable); var rec = result.CreateRecord(); rec["TextField"] = composite.StringValue; result.Insert(rec); result.Close(); result.Dispose(); com.Dispose(); con.Close(); con.Dispose(); } return composite; }

    - by asrijaal
    Hi, I'm trying to build a web service and a client for this service. I'm using Eclipse 3.5.1 with axis2-1.4.1. I'm facing a problem: I created the web service via the web service wizard and the service shows up in the axis service list. If I porint to the wsdl - its generated. Now when I'm trying to build the client, I choose the wsdl, the client project and take the next button, well at the client web service configuration everything is empty. There is nor service name, no port name. Am I facing a bug? Anyoneelse faced something like this? Regards

  • Best practices for managing limited client licenses/login

    - by MicSim
    I have a multi-user software solution (containing different applications, i.e. EXEs) that should allow only a limited number of concurrent users. It's designed to run in an intranet. I dont have a really good, satisfactory solution to the problem of counting the client licenses yet. The key requirements are: Multiple instances (starts) of the same application (= process) should count as only one client licence Starting different applications of the software solution should also count as only one (the same) client licence Application crash should not lead to orphaned used licences The above should work also for Terminal Server environments (all clients same IP, but different install folders) I'm looking for estabilished patterns, solutions, tips for managing used client licenses. Specific hints for the above sitaution are also welcome.

  • python Socket.IO client for sending broadcast messages to TornadIO2 server

    - by Alp
    I am building a realtime web application. I want to be able to send broadcast messages from the server-side implementation of my python application. Here is the setup: socketio.js on the client-side TornadIO2 server as Socket.IO server python on the server-side (Django framework) I can succesfully send socket.io messages from the client to the server. The server handles these and can send a response. In the following i will describe how i did that. Current Setup and Code First, we need to define a Connection which handles socket.io events: class BaseConnection(tornadio2.SocketConnection): def on_message(self, message): pass # will be run if client uses socket.emit('connect', username) @event def connect(self, username): # send answer to client which will be handled by socket.on('log', function) self.emit('log', 'hello ' + username) Starting the server is done by a Django management custom method: class Command(BaseCommand): args = '' help = 'Starts the TornadIO2 server for handling socket.io connections' def handle(self, *args, **kwargs): autoreload.main(self.run, args, kwargs) def run(self, *args, **kwargs): port = settings.SOCKETIO_PORT router = tornadio2.TornadioRouter(BaseConnection) application = tornado.web.Application( router.urls, socket_io_port = port ) print 'Starting socket.io server on port %s' % port server = SocketServer(application) Very well, the server runs now. Let's add the client code: <script type="text/javascript"> var sio = io.connect('localhost:9000'); sio.on('connect', function(data) { console.log('connected'); sio.emit('connect', '{{ user.username }}'); }); sio.on('log', function(data) { console.log("log: " + data); }); </script> Obviously, {{ user.username }} will be replaced by the username of the currently logged in user, in this example the username is "alp". Now, every time the page gets refreshed, the console output is: connected log: hello alp Therefore, invoking messages and sending responses works. But now comes the tricky part. Problems The response "hello alp" is sent only to the invoker of the socket.io message. I want to broadcast a message to all connected clients, so that they can be informed in realtime if a new user joins the party (for example in a chat application). So, here are my questions: How can i send a broadcast message to all connected clients? How can i send a broadcast message to multiple connected clients that are subscribed on a specific channel? How can i send a broadcast message anywhere in my python code (outside of the BaseConnection class)? Would this require some sort of Socket.IO client for python or is this builtin with TornadIO2? All these broadcasts should be done in a reliable way, so i guess websockets are the best choice. But i am open to all good solutions.

  • Creating a web-service client directly from the source

    - by ben
    Hi, I am trying to generate the WS client jar directly from the @Webservice class(es). Let's take this example : package com.example.maven.jaxws.helloservice; import javax.jws.WebService; @WebService public class Hello { public String sayHello(String param) { ; return "Hello " + param; } } I can generate a war file and use glassfish to serve this webservice, and from there I can use the glassfish WSDL URL to generate the client sources. What I am trying to do is to skip the glassfish part. From my maven project defining the webservice, I would like to use the jaxws-maven-plugin to create the client classes but I cannot find any way to specify the actual URL of the webservice. It should be possible right? @see also http://stackoverflow.com/questions/2097789/creating-a-web-service-client-with-a-known-but-inaccessible-wsdl

  • Light-weight client/server DB?

    - by OverTheRainbow
    Hello, (This question falls between programming and finding a tool, so I guess I'll ask here in SO since it has more activity than SuperUser.) I like the simplicity of SQLite, but by design, it doesn't support concurrent access. The apps I write don't have heavy needs, so I'd like to avoid heavier solutions like MySQL that are more difficult to deploy (remote customers with usually no computer personnel). Does someone know of a good solution that would offer the following features? Client available for VB.Net applications The server itself doesn't have to be a .Net application. Actually, I'd rather a bare-metal server so that it can run even on embedded Linux hosts with less RAM/CPU than regular PC's Easy install: the client part should either be statically linked inside the client application or be available as a single DLL, and the server should just be a single EXE listening for queries, à la Fossil (http://www.fossil-scm.org) clients can locate the server on the LAN by broadcasting data picked up by the server, so users don't have to write down the IP address and paste it into each client open-source, or moderately priced closed-source Thank you.

  • SVN client on windows without administrator rights

    - by Liu Chang
    I am trying to install an svn client on a friend's work windows laptop without much success. It seems that everyone is using TortoiseSVN nowadays, which unfortunately doesn't install without administrator access. Is there any way around it or another client I can try? I don't need anything fancy - just basic http/https, but a GUI is very much preferred over a command line client. Thanks!

  • PHP client for asmx service

    - by Carlos Mora
    A few days ago I was in charge of the development of some webServices for a client, the thing is that the client also asked for a php client that consumes the webservices. The service were published online on a server, with public access, right now I can see the wsdl from any computer, but when trying to consume it with PHP it shows me an error that says something about HTTP header and blablabla, that happened before I connected with a VPN to the server where the service is being hosted, after doing the VPN just by curiosity I reloaded the php client, and I don't know why... It did worked.... Q: Can anybody tell me why did this happened?

  • Measuring Web Page Performance on Client vs. Server

    - by Yaakov Ellis
    I am working with a web page (ASP.net 3.5) that is very complicated and in certain circumstances has major performance issues. It uses Ajax (through the Telerik AjaxManager) for most of its functionality. I would like to be able to measure in some way the amounts of time for the following, for each request: On client submitting request to server Client-to-Server On server initializing request On server processing request Server-to-Client Client rendering, JavaScript processing I have monitored the database traffic and cannot find any obvious culprit. On the other hand, I have a suspicion that some of the Ajax interactions are causing performance issues. However, until I have a way to track the times involved, make a baseline measurement, and measure performance as I tweak, it will be hard to work on the issue. So what is the best way to measure all of these? Is there one tool that can do it? Combination of FireBug and logging inserted into different places in the page life-cycle?

  • client-side synchronous service invocation

    - by qkrsppopcmpt
    I am talking about synchronous on the client side. That means, the service requester is blocking after sending a message to the service. my question is: is it related to the -a -s parameter of wsdl2java tool, Since -a generate async style code and -s generate sync style code. Or the client side blocking or not is totally controlled by the client logic? Thanks

  • Future proofing client-server code?

    - by Koran
    Hi, We have a web based client-server product. The client is expected to be used in the upwards of 1M users (a famous company is going to use it). Our server is set up in the cloud. One of the major questions while designing is how to make the whole program future proof. Say: Cloud provider goes down, then move automatically to backup in another cloud Move to a different server altogether etc The options we thought till now are: DNS: Running a DNS name server on the cloud ourselves. Directory server - The directory server also lives on the cloud Have our server returning future movements and future URLs etc to the client - wherein the client is specifically designed to handle those scenarios Since this should be a usual problem, which is the best solution for the same? Since our company is a very small one, we are looking at the least technically and financially expensive solution (say option 3 etc)? Could someone provide some pointers for the same? K

  • How to know if the client has terminated in sockets

    - by shadyabhi
    Suppose, I have a connected socket after writing this code.. if ((sd = accept(socket_d, (struct sockaddr *)&client_addr, &alen)) < 0) { perror("accept failed\n"); exit(1); } How can I know at the server side that client has exited. My whole program actually does the following.. Accepts a connection from client Starts a new thread that reads messages from that particular client and then broadcast this message to all the connected clients. If you want to see the whole code...
