  • Client unable to reach Internet through OpenVPN

    - by Carroarmato0
    The clients can all connect through OpenVPN. OpenVPN serves the following pool: server 10.8.0.0 255.255.255.0 I've configured the server's iptable with the following rule: iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE and echo 1 /proc/sys/net/ipv4/ip_forward This used to work back on the old vps I used. Now I've migrated to a vps which has ipv6 connectivity. Is it possible that Ipv6 has something to do with the fact that the clients can't reach the internet?

  • ftp-client works fine. ftp-tls-client fails on one computer and works on another

    - by ispiro
    Connecting to ftp - from a Windows Server 2012 - it works both secure (-over tls) and unsecure. From a Windows 7 it succeeds unsecure but fails when secure. (Using explicit TLS and passive mode.) filezilla: 234 AUTH command ok. Expecting TLS Negotiation. Initializing TLS... Connection timed out I've tried many things but nothing helps. (I'm also trying this programmatically. For details see: http://stackoverflow.com/questions/25393716/ftp-ssl-fails-after-expecting-tls-negotiation ) The fact that it does succeed from one computer proves that the ftp server is fine. And the fact that the Windows 7 computer succeeds without tls proves that it's not a NAT/firewall problem (besides, it failed even after disabling firewall etc.). I'm not sure where to start looking. Perhaps a difference between PC Windows and Windows Server? EDIT The ftp server is on a Windows Server 2012.

  • FTP client hangs after a while

    - by lfbn
    I'm using Linux Ubuntu 12.04 with curlftpfs to connect to a remote server. After mounting a remote ftp, opening and saving files with vim, list directories and files, for some time, after a while (no more of 30 minutes), with no reason it hangs. After opening other terminal tabs, all tabs remain iddle...but when using filezilla without restart the computer I still can get to the server and working with no problem. When using Nautilus, instead of curlftpfs, I'm having the same problem. After a while it hangs. Can anyone help me please?

  • SSAS processing error: Client unable to establish connection; 08001; Encryption not supported on the client.; 08001

    - by Kevin Shyr
    After getting the cube to successfully deploy and process on Friday, I was baffled on Monday that the newly added dimension caused the cube processing to break.  I then followed the first instinct, discarded all my changes to reverted back to the version on Friday, and had no luck.  The error message (attached below) did not help as I was looking for some kind of SQL service error.  After examining the windows server log and the SQL server log, I just couldn't see anything wrong with it.After swearing for some time, and with the help of going off and working on something else for a while.  I came back to the solution and looked at the data source.  Even though I know I have never changed the provider (the default setup gave me SQL native client), I decided to change it and give OLE DB a try.This simple change allows my cube to process successfully again.  While I don't understand why the same settings that worked last week doesn't work this week, I don't have all the information to say with certainty that nothing has changed in the environment (firewall changes, server updates, etc.).SSAS processing error:<Batch >  <Parallel>    <Process xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ddl2="http://schemas.microsoft.com/analysisservices/2003/engine/2" xmlns:ddl2_2="http://schemas.microsoft.com/analysisservices/2003/engine/2/2" xmlns:ddl100_100="http://schemas.microsoft.com/analysisservices/2008/engine/100/100" xmlns:ddl200="http://schemas.microsoft.com/analysisservices/2010/engine/200" xmlns:ddl200_200="http://schemas.microsoft.com/analysisservices/2010/engine/200/200">      <Object>        <DatabaseID>DWH Sales Facts</DatabaseID>        <CubeID>DWH Sales Facts</CubeID>      </Object>      <Type>ProcessFull</Type>      <WriteBackTableCreation>UseExisting</WriteBackTableCreation>    </Process>  </Parallel></Batch>                Processing Dimension 'Date' completed.                                Errors and Warnings from Response                OLE DB error: OLE DB or ODBC error: A network-related or instance-specific error has occurred while establishing a connection to SQL Server.

  • MVC 3 Client Validation works intermittently

    - by Gutek
    I have MVC 3 version, System.Web.Mvc product version is: 3.0.20105.0 modified on 5th of Jan 2011 - i think that's the latest. I’ve notice that client validation is not working as it suppose in the application that we are creating, so I’ve made a quick test. I’ve created basic MVC 3 Application using Internet Application template. I’ve added Test Controller: using System.Web.Mvc; using MvcApplication3.Models; namespace MvcApplication3.Controllers { public class TestController : Controller { public ActionResult Index() { return View(); } public ActionResult Create() { Sample model = new Sample(); return View(model); } [HttpPost] public ActionResult Create(Sample model) { if(!ModelState.IsValid) { return View(); } return RedirectToAction("Display"); } public ActionResult Display() { Sample model = new Sample(); model.Age = 10; model.CardNumber = "1324234"; model.Email = "[email protected]"; model.Title = "hahah"; return View(model); } } } Model: using System.ComponentModel.DataAnnotations; namespace MvcApplication3.Models { public class Sample { [Required] public string Title { get; set; } [Required] public string Email { get; set; } [Required] [Range(4, 120, ErrorMessage = "Oi! Common!")] public short Age { get; set; } [Required] public string CardNumber { get; set; } } } And 3 views: Create: @model MvcApplication3.Models.Sample @{ ViewBag.Title = "Create"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Create</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @*@{ Html.EnableClientValidation(); }*@ @using (Html.BeginForm()) { @Html.ValidationSummary(false) <fieldset> <legend>Sample</legend> <div class="editor-label"> @Html.LabelFor(model => model.Title) </div> <div class="editor-field"> @Html.EditorFor(model => model.Title) @Html.ValidationMessageFor(model => model.Title) </div> <div class="editor-label"> @Html.LabelFor(model => model.Email) </div> <div class="editor-field"> @Html.EditorFor(model => model.Email) @Html.ValidationMessageFor(model => model.Email) </div> <div class="editor-label"> @Html.LabelFor(model => model.Age) </div> <div class="editor-field"> @Html.EditorFor(model => model.Age) @Html.ValidationMessageFor(model => model.Age) </div> <div class="editor-label"> @Html.LabelFor(model => model.CardNumber) </div> <div class="editor-field"> @Html.EditorFor(model => model.CardNumber) @Html.ValidationMessageFor(model => model.CardNumber) </div> <p> <input type="submit" value="Create" /> </p> </fieldset> @*<fieldset> @Html.EditorForModel() <p> <input type="submit" value="Create" /> </p> </fieldset> *@ } <div> @Html.ActionLink("Back to List", "Index") </div> Display: @model MvcApplication3.Models.Sample @{ ViewBag.Title = "Display"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Display</h2> <fieldset> <legend>Sample</legend> <div class="display-label">Title</div> <div class="display-field">@Model.Title</div> <div class="display-label">Email</div> <div class="display-field">@Model.Email</div> <div class="display-label">Age</div> <div class="display-field">@Model.Age</div> <div class="display-label">CardNumber</div> <div class="display-field">@Model.CardNumber</div> </fieldset> <p> @Html.ActionLink("Back to List", "Index") </p> Index: @{ ViewBag.Title = "Index"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Index</h2> <p> @Html.ActionLink("Create", "Create") </p> <p> @Html.ActionLink("Display", "Display") </p> Everything is default here – Create Controller, AddView from controller action with model specified with proper scaffold template and using provided layout in sample application. When I will go to /Test/Create client validation in most cases works only for Title and Age fields, after clicking Create it works for all fields (create does not goes to server). However in some cases (after a build) Title validation is not working and Email is, or CardNumber or Title and CardNumber but Email is not. But never all validation is working before clicking Create. I’ve tried creating form with Html.EditorForModel as well as enforce client validation just before BeginForm: @{ Html.EnableClientValidation(); } I’m providing a source code for this sample on dropbox – as maybe our dev env is broken :/ I’ve done tests on IE 8 and Chrome 10 beta. Just in case, in web config validation scripts are enabled: <appSettings> <add key="ClientValidationEnabled" value="true"/> <add key="UnobtrusiveJavaScriptEnabled" value="true"/> </appSettings> So my questions are Is there a way to ensure that Client validation will work as it supposed to work and not intermittently? Is this a desired behavior and I'm missing something in configuration/implementation?

  • How to notify client about updated UpdatePanel content on server side

    - by csh1981
    I have a problem with UpdatePanel.Update() which works initially but then stops. I have tumbled with this problem for some time and some background is needed so please read ahead. I have an ASP.net application in which I have a subpage that display computed information in graphs. Each graph is embedded in an UpdatePanel. The graph is a user control that uses the standard asp:Chart for display. My task is to enable this page with AJAX capabilities so the page is responsive during postbacks. When I access this page from another page, during the initial page rendering, I use a wait dialog for each graph and a pageload event on the client side. In the client event, a hidden button is clicked which a server event handles (the hidden button is inside an UpdatePanel so the postback is asynchronous). Each graph is computed and the UpdatePanels are in turn updated with the Chart content. This is done using UpdatePanel.Update. And it is successful. However, I also have some RadioButtons on the page. These are dynamically created. The purpose of them is to switch graph type --- to show the same data in a different way. Same type of time consuming computation is needed in order to do so. I subscribe on each RadioButton's OnCheckedChanged event and the postback is asynchronous since the radiobuttons are inside an UpdatePanel. In the server event handler I determine the type of graph and use this as an input to the Chart control. I then remove the old Chart control from my Panel and adds new Chart and then I call UpdatePanel.Update(). But with no success. Nothing happens, no errors, nothing. Why is this?? I think this is strange because if I compute every Chart data in the initial rendering instead of using the "Wait dialog"-solution described earlier then I can select graph types successfully and all subsequent AJAX requests work as intended. Also, the same code (computing the chart, removal, and adding the Chart control to Panel and UpdatePanel.Update()) is hit during the initial rendering of the page, and it works only the first time. Here is the method that computes the graph and adds it to the panel and update the UpdatePanel: public void UpdateGraph(GraphType type, GraphMapper mapper) { //Panel is the content of UpdatePanelGraph's Panel.Controls.Clear(); chart = new Chart(type, mapper); //Computation happens inside here panel.Controls.Add(chart); //UpdatePanelGraph is in UpdateMode Conditional and has //ChildrenAsTriggers set to false UpdatePanelGraph.Update(); } I really need a way for these radiobuttons to work, possible using some clientside JavaScript or another way of handling things on the server side. I have thought about using a JavaScript postback call on the UpdatePanel instead of the UpdatePanel.Update(). However, the issue I have here is how to notify the client side when the server side is finished with computing the graph? An plausible explanation of the strange behavior is also much appreciated. Any help appreciated, thanks

  • client-side validation in custom validation attribute - asp.net mvc 4

    - by Giorgos Manoltzas
    I have followed some articles and tutorials over the internet in order to create a custom validation attribute that also supports client-side validation in an asp.net mvc 4 website. This is what i have until now: RequiredIfAttribute.cs [AttributeUsage(AttributeTargets.Property, AllowMultiple = true)] //Added public class RequiredIfAttribute : ValidationAttribute, IClientValidatable { private readonly string condition; private string propertyName; //Added public RequiredIfAttribute(string condition) { this.condition = condition; this.propertyName = propertyName; //Added } protected override ValidationResult IsValid(object value, ValidationContext validationContext) { PropertyInfo propertyInfo = validationContext.ObjectType.GetProperty(this.propertyName); //Added Delegate conditionFunction = CreateExpression(validationContext.ObjectType, _condition); bool conditionMet = (bool)conditionFunction.DynamicInvoke(validationContext.ObjectInstance); if (conditionMet) { if (value == null) { return new ValidationResult(FormatErrorMessage(null)); } } return ValidationResult.Success; } private Delegate CreateExpression(Type objectType, string expression) { LambdaExpression lambdaExpression = System.Linq.Dynamic.DynamicExpression.ParseLambda(objectType, typeof(bool), expression); //Added Delegate function = lambdaExpression.Compile(); return function; } public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context) { var modelClientValidationRule = new ModelClientValidationRule { ValidationType = "requiredif", ErrorMessage = ErrorMessage //Added }; modelClientValidationRule.ValidationParameters.Add("param", this.propertyName); //Added return new List<ModelClientValidationRule> { modelClientValidationRule }; } } Then i applied this attribute in a property of a class like this [RequiredIf("InAppPurchase == true", "InAppPurchase", ErrorMessage = "Please enter an in app purchase promotional price")] //Added "InAppPurchase" public string InAppPurchasePromotionalPrice { get; set; } public bool InAppPurchase { get; set; } So what i want to do is display an error message that field InAppPurchasePromotionalPrice is required when InAppPurchase field is true (that means checked in the form). The following is the relevant code form the view: <div class="control-group"> <label class="control-label" for="InAppPurchase">Does your app include In App Purchase?</label> <div class="controls"> @Html.CheckBoxFor(o => o.InAppPurchase) @Html.LabelFor(o => o.InAppPurchase, "Yes") </div> </div> <div class="control-group" id="InAppPurchasePromotionalPriceDiv" @(Model.InAppPurchase == true ? Html.Raw("style='display: block;'") : Html.Raw("style='display: none;'"))> <label class="control-label" for="InAppPurchasePromotionalPrice">App Friday Promotional Price for In App Purchase: </label> <div class="controls"> @Html.TextBoxFor(o => o.InAppPurchasePromotionalPrice, new { title = "This should be at the lowest price tier of free or $.99, just for your App Friday date." }) <span class="help-inline"> @Html.ValidationMessageFor(o => o.InAppPurchasePromotionalPrice) </span> </div> </div> This code works perfectly but when i submit the form a full post is requested on the server in order to display the message. So i created JavaScript code to enable client-side validation: requiredif.js (function ($) { $.validator.addMethod('requiredif', function (value, element, params) { /*var inAppPurchase = $('#InAppPurchase').is(':checked'); if (inAppPurchase) { return true; } return false;*/ var isChecked = $(param).is(':checked'); if (isChecked) { return false; } return true; }, ''); $.validator.unobtrusive.adapters.add('requiredif', ['param'], function (options) { options.rules["requiredif"] = '#' + options.params.param; options.messages['requiredif'] = options.message; }); })(jQuery); This is the proposed way in msdn and tutorials i have found Of course i have also inserted the needed scripts in the form: jquery.unobtrusive-ajax.min.js jquery.validate.min.js jquery.validate.unobtrusive.min.js requiredif.js BUT...client side validation still does not work. So could you please help me find what am i missing? Thanks in advance.

  • D-Link DIR-300 slows down / loses network

    - by basic6
    Hi there, there are 2 buildings (A and B). In bldg A is an open WLAN (which I'm allowed to use btw). In bldg B is a computer that I want to connect to that network. So I flashed an old D-Link DIR-300 AP with DD-WRT, mounted it to the wall (bldg B) near a window, attached a 13 dBi directional antenna (pointing to bldg A) and configured it as AP client in that wireless network. Then there's another AP, connected to the D-Link AP, acting as standard access point, which the computer is connected to. That's basically working so far, but: Every now and then the connection is lost. Not the connection between the computer and the D-Link (I can access the DD-WRT admin page normally) or the connection between the D-Link and the WLAN (in Status - Wireless it says it's still connected to the network), but when I want to access a web page (which only works if I'm connected to the wireless network from bldg A), my Firefox keeps "Looking for" (name resolution) without finding anything. When I reset the D-Link (power off, power on) in this situation, after some moments, everything's working fine again (Internet access). I've no idea why this is happening, but usually it's at most every few weeks (most times when nobody was using the computer, so no traffic). Compared to the connection speed when I connect directly to the WLAN in bldg A (Laptop), the speed in bldg B is rather slow, but I have the impression that this difference is worse in the last few days. A few minutes ago, I got 582 KB/s down and 911 KB/s up in bldg A (directly/laptop) and 84 KB/s down and 9 KB/s up in bldg B. The speed in bldg B used to be way higher (I remember 200 KB/s up) while the actual network speed in bldg A was lower than it is now (close to those 200). I'm aware that the wireless connection between those buildings should slow things down, but I'm wondering why this difference has become that extreme. Thanks for any tips... Update: I currently want to upload a large file (1.5 GB) via FTP (FileZilla). Since that caused the D-Link to disconnect (as described in first post), I took my laptop to bldg A, connected directly to the original WLAN (bypassing my D-Link) and tried the same upload. Guess what - same issue: At some point the connection is dead (at this point I would have reset my D-Link if I was connected to it). Just as the D-Link, my laptop is still connected, but not even name resolution is working ("Looking for..." in Firefox). After reconnecting, it's working again. Maybe my D-Link isn't the problem at all...

  • Random DNS Client Issue with BIND9/Windows Server 2003 DNS

    - by upkels
    Within our office, we have a local server running DNS, for internal related "domains", (e.g. .internal, .office, .lan, .vpn, etc.). Randomly, only the hosts configured with those extensions will stop resolving on the Windows-based workstations. Sometimes it'll work for a couple weeks without issue on one machine, then suddenly stop working, or it'll happen on another 15 times per day. It's completely random for all workstations. When troubleshooting, I have opened up a command prompt, and issued various nslookup commands for some of these hosts, and they resolve, however I've been told that nslookup uses different "libraries" for name resolution than other applications such as web browsers, email clients, etc. The only solution thus far, is manually restarting the Windows DNS Client on each workstation when this happens. Issuing the ipconfig /flushdns command multiple times helps every now and then, but is not successful enough to even attempt before restarting the DNS Client. I have tried two different DNS servers; BIND9, and Windows Server 2003 R2 DNS, and the behavior is the same. We have a single Netgear JGS524 switch all workstations and servers are connected to within the office, and a Linksys SR224G switch in another department with workstations attached.

  • MVC2 client/server validation of DateTime/Date using DataAnnotations

    - by Thomas
    The following are true: One of my columns (BirthDate) is of type Date in SQL Server. This very same column (BirthDate) is of type DateTime when EF generates the model. I am using JQuery UI Datepicker on the client side to be able to select the BirthDate. I have the following validation logic in my buddy class: [Required(ErrorMessageResourceType = typeof(Project.Web.ValidationMessages), ErrorMessageResourceName = "Required")] [RegularExpression(@"\b(0?[1-9]|1[012])[/](0?[1-9]|[12][0-9]|3[01])[/](19|20)?[0-9]{2}\b", ErrorMessageResourceType = typeof(Project.Web.ValidationMessages), ErrorMessageResourceName = "Invalid")] public virtual DateTime? BirthDate { get; set; } There are two issues with this: This will not pass server side validation (if I enable client side validation it works just fine). I am assuming that this is because the regular expression doesn't take into account hours, minutes, seconds as the value in the text box has already been cast as a DateTime on the server by the time validation occurs. If data already exists in the database and is read into the model and displayed on the page the BirthDate field shows hours, minutes, seconds in my text box (which I don't want). I can always use ToShortDateString() but I am wondering if there is some cleaner approach that I might be missing. Thanks

    if I want to use the following Web service (help.be is just an example, let's say it does exist): http://www.help.be/webservice/webservice_help.php (it's written in PHP=client's choice, not .NET) with the following WSDL : <?xml version="1.0" encoding="UTF-8"?> <definitions xmlns="http://schemas.xmlsoap.org/wsdl/" name="webservice_help" targetNamespace="http://www.help.be/webservice/webservice_help.php" xmlns:tns="http://www.help.be/webservice/webservice_help.php" xmlns:impl="http://www.help.be/webservice/webservice_help.php" xmlns:xsd1="http://www.help.be/webservice/webservice_help.php" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"> <portType name="webservice_helpPortType"> <operation name="webservice_help"> <input message="tns:Webservice_helpRequest"/> </operation> <operation name="getLocation" parameterOrder="input"> <input message="tns:GetLocationRequest"/> <output message="tns:GetLocationResponse"/> </operation> <operation name="getStationDetail" parameterOrder="input"> <input message="tns:GetStationDetailRequest"/> <output message="tns:GetStationDetailResponse"/> </operation> <operation name="getStationList" parameterOrder="input"> <input message="tns:GetStationListRequest"/> <output message="tns:GetStationListResponse"/> </operation> </portType> <binding name="webservice_helpBinding" type="tns:webservice_helpPortType"> <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/> <operation name="webservice_help"> <soap:operation soapAction="urn:webservice_help#webservice_helpServer#webservice_help"/> <input> <soap:body use="encoded" namespace="http://www.help.be/webservice/webservice_help.php" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> </input> </operation> <operation name="getLocation"> <soap:operation soapAction="urn:webservice_help#webservice_helpServer#getLocation"/> <input> <soap:body parts="input" use="encoded" namespace="http://www.help.be/webservice/webservice_help.php" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> </input> <output> <soap:body parts="return" use="encoded" namespace="http://www.help.be/webservice/webservice_help.php" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> </output> </operation> <operation name="getStationDetail"> <soap:operation soapAction="urn:webservice_help#webservice_helpServer#getStationDetail"/> <input> <soap:body parts="input" use="encoded" namespace="http://www.help.be/webservice/webservice_help.php" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> </input> <output> <soap:body parts="return" use="encoded" namespace="http://www.help.be/webservice/webservice_help.php" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> </output> </operation> <operation name="getStationList"> <soap:operation soapAction="urn:webservice_help#webservice_helpServer#getStationList"/> <input> <soap:body parts="input" use="encoded" namespace="http://www.help.be/webservice/webservice_help.php" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> </input> <output> <soap:body parts="return" use="encoded" namespace="http://www.help.be/webservice/webservice_help.php" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> </output> </operation> </binding> <message name="Webservice_helpRequest"/> <message name="GetLocationRequest"> <part name="input" type="xsd:array"/> </message> <message name="GetLocationResponse"> <part name="return" type="xsd:array"/> </message> <message name="GetStationDetailRequest"> <part name="input" type="xsd:array"/> </message> <message name="GetStationDetailResponse"> <part name="return" type="xsd:string"/> </message> <message name="GetStationListRequest"> <part name="input" type="xsd:array"/> </message> <message name="GetStationListResponse"> <part name="return" type="xsd:string"/> </message> <service name="webservice_helpService"> <port name="webservice_helpPort" binding="tns:webservice_helpBinding"> <soap:address location="http://www.help.be/webservice/webservice_help.php"/> </port> </service> </definitions> What is the correct SOAP_ACTION, METHOD_NAME, NAMESPACE, URL I should use below ?

  • EJB3 JNDI Lookup Failure in JEE application client

    - by Hank
    I'm trying to access an EJB3 from a JEE client-application, but keep getting nothing but lookup failures. My JEE Application 'CoreServer' is exposing a number of beans with remote interfaces. I have no problem accessing them from a Web Application deployed on the same Glassfish v3.0.1. Now I'm trying to access it from a client-application: public class Main { public static void main(String[] args) { CampaignControllerRemote bean = null; try { InitialContext ctx = new InitialContext(); bean = (CampaignControllerRemote) ctx.lookup("java:global/CoreServer/CampaignController"); } catch (Exception e) { System.out.println(e.getMessage()); } if (bean != null) { Campaign campaign = bean.get(361); if (campaign != null) { System.out.println("Got "+ campaign); } } } } When I run deploy it to Glassfish and run it from the appclient, I get this error: Lookup failed for 'java:global/CoreServer/CampaignController' in SerialContext targetHost=localhost,targetPort=3700,orb'sInitialHost=localhost,orb'sInitialPort=3700 However, that's exactly the same JNDI-name I use when I lookup the bean from the WebApplication (via SessionContext, not InitialContext - does that matter?). Also, when I deploy 'CoreServer', Glassfish reports: Portable JNDI names for EJB CampaignController : [java:global/CoreServer/CampaignController!mvs.api.CampaignControllerRemote, java:global/CoreServer/CampaignController] Glassfish-specific (Non-portable) JNDI names for EJB CampaignController : [mvs.api.CampaignControllerRemote, mvs.api.CampaignControllerRemote#mvs.api.CampaignControllerRemote] I tried all four names, none worked. Is the appclient unable to access beans with (only) Remote interfaces?

  • Weird certificate error when trying to generate web service client from secure site

    - by Vlad
    Dear stack overflow. I get a weird error when trying to use AXIS1.4 Wsdl2Java tool to generate client code for the web service that is installed on the secure IIS site. When I run the tool I get the following SSL exception: javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No name matching XXXXXXX.net found at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Alerts.java:174) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1 591) at com.sun.net.ssl.internal.ssl.Handshaker.fatalSE(Handshaker.java:187) at com.sun.net.ssl.internal.ssl.Handshaker.fatalSE(Handshaker.java:181) at com.sun.net.ssl.internal.ssl.ClientHandshaker.serverCertificate(Clien tHandshaker.java:975) at com.sun.net.ssl.internal.ssl.ClientHandshaker.processMessage(ClientHa ndshaker.java:123) at com.sun.net.ssl.internal.ssl.Handshaker.processLoop(Handshaker.java:5 16) at com.sun.net.ssl.internal.ssl.Handshaker.process_record(Handshaker.jav a:454) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.j ava:884) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.performInitialHandshake(SS LSocketImpl.java:1096) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.startHandshake(SSLSocketIm pl.java:1123) Weird thing is that this error only occurs when I run WSDL2Java, and only for this particular server. I have another web server with the identical set-up and everything works fine there. I triple checked all the keystores and it looks like all the CA certificates are loaded correctly. I tried using another server with the identical setup, and was able to generate the client proxy code without any problems. Weird thing is that if I use the code generated from the other server against the weird server everything works fine. It is only Wsdl2Java that is giving me a problem.

  • Does SmtpClient class represent POP3 client or…?

    - by SourceC
    I assume that web controls (such as the PasswordRecovery control) use SmtpClient to send email messages. If so, does SmtpClient represent a POP3 client or does SmtpClient forward email message to POP3 client? Do attributes specified inside <smtp> element in web.config map to SmtpClient class? <system.net> <mailSettings> <smtp deliveryMethod="Network" ...></smtp> </mailSettings> </system.net> One of the possible values for the attribute deliveryMethod is Network, which tells that email should be sent through the network to an SMTP server. In other words, this value tells to send email to SMTP server using SMTP protocol?! For the PasswordRecovery control to be able to send email messages, we need to set basic properties in <MailDefinition> subelement of the PasswordRecovery control. Thus I assume MailDefinition is used by controls to create an email message?!

  • WCF 3.5 to 3.0 backwards compatibility with callback services

    - by Miral
    I have a set of existing WCF services hosted in a .NET 3.0 app. They're using the WSHttp bindings and no security. I need to connect to these from a .NET 3.5 client. This seems to be working fine for the one-way services, but I also have some callback services (with CallbackContract and SessionMode = Required, using WSDualHttpBinding); these fail to connect with a timeout somewhere in the ReliableSession code. The service side cannot be changed (it's a historic version issue). Can I modify something on the client side to get this working? (I can connect with a .NET 3.0 client just fine, but I'd rather not be forced to try that path.) The open operation did not complete within the allotted timeout of 00:00:09.9410000. The time allotted to this operation may have been a portion of a longer timeout. Server stack trace: at System.ServiceModel.Channels.ReliableRequestor.ThrowTimeoutException() at System.ServiceModel.Channels.ReliableRequestor.Request(TimeSpan timeout) at System.ServiceModel.Channels.ClientReliableSession.Open(TimeSpan timeout) at System.ServiceModel.Channels.ClientReliableDuplexSessionChannel.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout)

  • IPhone app with SSL client certs

    - by Pavel Georgiev
    I'm building an iphone app that needs to access a web service over https using client certificates. If I put the client cert (in pkcs12 format) in the app bundle, I'm able to load it into the app and make the https call (largely thanks to stackoverflow.com). However, I need a way to distribute the app without any certs and leave it to the user to provide his own certificate. I thought I would just do that by instructing the user to import the certificate in iphone's profiles (settings-general-profiles), which is what you get by opening a .p12 file in Mail.app and then I would access that item in my app. I would expect that the certificates in profiles are available through the keychain API, but I guess I'm wrong on that. 1) Is there a way to access a certificate that I've already loaded in iphone's profile in my app? 2) What other options I have for loading a user specified certificate in my app? The only thing I can come up with is providing some interface where the user can give an URL to his .p12 cerificate, which I can then load into the app's keychain for later use, but thats not exactly user-friednly. I'm looking for something that would allow the user to put the cert on phone (email it to himself) and then load it in my app.

  • Browser Based Streaming Video/Audio (not progressive download)

    - by Josh
    Hello, I am trying to understand conceptually the best way to deliver real streaming audio and video content. I would want it to be consumed with a web browser, utilizing the least amount of proprietary technology. I wouldn't be serving static files and using progressive download, this would be real audio streams being captured live. How does one broadcast a stream that will be reasonably in sync with the source? What kind of protocol is suitable? Edit: In research I've found that there are a few protocols: RTSP, HTTP Streaming, RTMP, and RTP. HTTP streaming is somewhat unsuitable if you are streaming a live performance/communication of some kind because it relies on TCP (as its HTTP based) and you don't lose packets. In a low bandwidth situation, the client can get significantly behind in playback. ref RTMP is a proprietary technology, requiring flash media server. Crap on that. The reason I looked at flash is because they are extremely flexible as far as user experience goes. SoundManager2 provides an excellent javascript interface for playing media with flash. This is what I would look for in a client application. RTSP/RTP is what Microsoft switched to using, deprecating their MMS protocol. RTSP is the control protocol. Its similar to HTTP with a few distinct difference -- server can also talk to the client, and there are additional commands, like PAUSE. Its also a stateful protocol, which is maintained with a session id. RTP is the protocol for delivering the payload (encoded audio or video). There are a few open sourced projects, one of them being supported by apple here. It seems like this might do what I want it to, and it looks like quite a few players support it. It sounds like it would be suitable for a "live" broadcast from this page here. Thanks, Josh

  • How do I securely authenticate the calling assembly of a WCF service method?

    - by Tim
    The current situation is as follows: We have an production .net 3.5 WCF service, used by several applications throughout the organization, over wsHttpBinding or netTcpBinding. User authentication is being done on the Transport level, using Windows integrated security. This service has a method Foo(string parameter), which can only be called by members of given AD groups. The string parameter is obligatory. A new client application has come into play (.net 3.5, C# console app), which eliminates the necessity of the string parameter. However, only calls from this particular application should be allowed to omit the string parameter. The identity of the caller of the client application should still be known by the server because the AD group limitation still applies (ruling out impersonation on the client side). I found a way to pass on the "evidence" of the calling (strong-named) assembly in the message headers, but this method is clearly not secure because the "evidence" can easily be spoofed. Also, CAS (code access security) seems like a possible solution, but I can't seem to figure out how to make use of CAS in this particular scenario. Does anyone have a suggestion on how to solve this issue? Edit: I found another thread on this subject; apparently the conclusion there is that it is simply impossible to implement in a secure fashion.

  • Upload image from J2ME client to a Servlet

    - by Akash
    I want to send an image from a J2ME client to a Servlet. I am able to get a byte array of the image and send it using HTTP POST. conn = (HttpConnection) Connector.open(url, Connector.READ_WRITE, true); conn.setRequestMethod(HttpConnection.POST); conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); os.write(bytes, 0, bytes.length); // bytes = byte array of image This is the Servlet code: String line; BufferedReader r1 = new BufferedReader(new InputStreamReader(in)); while ((line = r1.readLine()) != null) { System.out.println("line=" + line); buf.append(line); } String s = buf.toString(); byte[] img_byte = s.getBytes(); But the problem I found is, when I send bytes from the J2ME client, some bytes are lost. Their values are 0A and 0D hex. Exactly, the Carriage Return and Line Feed. Thus, either POST method or readLine() are not able to accept 0A and 0D values. Any one have any idea how to do this, or how to use any another method?

  • I need git-svn to act as a Subversion v1.5+ client

    - by Ben Ward
    I'm running git 1.7 on Mac OSX, installed via Homebrew. I'm trying to use git svn to work with a Subversion server that requires Subversion 1.5 clients (a restriction enforced via a pre-commit hook.) Running git svn --version reveals that as far as git is concerned, git svn is equivalent to svn v1.4.4. I can't establish whether git svn is a total clone of subversion, and thus needs to be updated to meet subversion v1.5 functionality, or if git is compiled against or just points to some version of subversion under the hood. I've struggled finding anyone else trying to upgrade the version of git-svn, and I'm guessing this client version restriction is unusual, but I'm stuck with it (corporate environment.) Is it possible to have git operate as svn 1.5?

  • Collection is empty when it arrives on the client

    - by digiduck
    One of my entities has an EntitySet< property with [Composition], [Include] and [Association] attributes. I populate this collection in my domain service but when I check its contents when it is received on the client, the collection is empty. I am using Silverlight 4 RTM as well as RIA Services 1.0 RTM. Any ideas what I am doing wrong? Here is the code on my service side: public class RegionDto { public RegionDto() { Cities = new EntitySet<CityDto>(); } [Key] public int Id { get; set; } public string Name { get; set; } [Include] [Composition] [Association("RegionDto_CityDto", "Id", "RegionId")] public EntitySet<CityDto> Cities { get; set; } } public class CityDto { [Key] public int Id { get; set; } public int RegionId { get; set; } public string Name { get; set; } } [EnableClientAccess()] public class RegionDomainService : LinqToEntitiesDomainService<RegionEntities> { public IEnumerable<RegionDto> GetRegions() { var regions = (ObjectContext.Regions .Select(x => new RegionDto { Id = x.ID, Name = x.Name })).ToList(); foreach (var region in regions) { var cities = (ObjectContext.Cities .Where(x => x.RegionID == region.Id) .Select(x => new CityDto { Id = x.ID, Name = x.Name })).ToList(); foreach (var city in cities) { region.Cities.Add(city); } } // each region's Cities collection is populated at this point // however when the client receives it, the Cities collections are all empty return regions; } }
