  • Winsock Connect Problem with Eset Nod32

    - by AFgone
    Dear All, my socket library which is implemented using winsock2 is working properly. But when ESET Nod32 installed on the computer, connect() function returns 0(zero) ,that is success, even if remote host is not available. I looked with netstat -b command and saw that ekrn.exe is accepting the client. And after couple of seconds it sends zero byte of information,which means graceful close. So how can I overcome this problem? Many thanks, regards...

  • debugging JBoss 100% CPU usage

    - by NateS
    Originally posted on Server Fault, where it was suggested this question might better asked here. We are using JBoss to run two of our WARs. One is our web app, the other is our web service. The web app accesses a database on another machine and makes requests to the web service. The web service makes JMS requests to other machines, aggregates the data, and returns it. At our biggest client, about once a month the JBoss Java process takes 100% of all CPUs. The machine running JBoss has 8 CPUs. Our web app is still accessible during this time, however pages take about 3 minutes to load. Restarting JBoss restores everything to normal. The database machine and all the other machines are fine, only the machine running JBoss is affected. Memory usage is normal. Network utilization is normal. There are no suspect error messages in the JBoss logs. I have set up a test environment as close as possible to the client's production environment and I've done load testing with as much as 2x the number of concurrent users. I have not gotten my test environment to replicate the problem. Where do we go from here? How can we narrow down the problem? Currently the only plan we have is to wait until the problem occurs in production on its own, then do some debugging to determine the cause. So far people have just restarted JBoss when the problem occurred to minimize down time. Next time it happens they will get a developer to take a look. The question is, next time it happens, what can be done to determine the cause? We could setup a separate JBoss instance on the same box and install the web app separately from the web service. This way when the problem next occurs we will know which WAR has the problem (assuming it is our code). This doesn't narrow it down much though. Should I enable JMX remote? This way the next time the problem occurs I can connect with VisualVM and see which threads are taking the CPU and what the hell they are doing. However, is there a significant down side to enabling JMX remote in a production environment? Is there another way to see what threads are eating the CPU and to get a stacktrace to see what they are doing? Any other ideas? Thanks!

  • MacFUSE: Keepalive?

    - by Wilco
    Is there a way to configure MacFUSE to keep a mounted volume alive if the remote host is set to break the connection due to inactivity? If there is no direct way to configure this, would there be a way to write a script to accomplish this?

  • How do I force fetching of tags if I have the --no-tags option set

    - by douglas.meyer
    Whenever I run git fetch it fetches all the tags from origin. In a project with lots of tags, this can get quite bothersome. So I ran git config remote.origin.tagopt --no-tags so fetching will no-longer fetch tags. However, there are some times when I do want to fetch tags, or a single tag. Does anyone know how to do this? (besides removing that configuration, and running git fetch --no-tags every time) Thanks!

  • claimsResponse Always Return Null

    - by Chirag Pandya
    hello i have a following code in asp.net. i have used DotNetOpenAuth.dll for openID. the code is under protected void openidValidator_ServerValidate(object source, ServerValidateEventArgs args) { // This catches common typos that result in an invalid OpenID Identifier. args.IsValid = Identifier.IsValid(args.Value); } protected void loginButton_Click(object sender, EventArgs e) { if (!this.Page.IsValid) { return; // don't login if custom validation failed. } try { using (OpenIdRelyingParty openid = this.createRelyingParty()) { IAuthenticationRequest request = openid.CreateRequest(this.openIdBox.Text); // This is where you would add any OpenID extensions you wanted // to include in the authentication request.

  • Cross-Domain Cookie Problem

    - by Frederick
    Hi Guys, I have a domain A.com [my website] and a remote website B.com which integrates an iframe from my domain [A.com] with a piece of javascript. I want to share cookies across these domains [within the iframe]? How would I go about doing this so it works properly? I thought A.com and B.com are in the same-origin policy ?

  • Windows 2008R2 two node failover cluster creation fails

    - by Francois Wolmarans
    We have just installed two Windows 2008R2 Enterprise machines with identical hardware. When running the cluster validation everything is ok. When creating the cluster it fails with the following error: An error occurred while creating the cluster. An error occurred creating cluster 'CLUSTER04'. The parameter is incorrect The logfile on the first node where we are running our config from, does not show any errors. On the second node we get: The Cluster service is shutting down because quorum was lost. This could be due to the loss of network connectivity between some or all nodes in the cluster, or a failover of the witness disk. I've double checked and all communication between the servers are fine. Even when creating a one node cluster it gives the error. There are other failover clusters we have setup without any issues.

  • JBoss ignores @RemoteBinding annotation

    - by tputkonen
    I would like to specify JNDI name for an EJB3 bean using annotation, but JBoss 5.1.0 GA seems to ignore the annotation completely. Bean's annotations are: @Remote(Foobar.class) @Stateless(name = "Foobar") @TransactionManagement(TransactionManagementType.BEAN) @RemoteBinding(jndiBinding="ejb/Foobar") public class FoobarBean implements Foobar { ... I tested deploying also using @RemoteBindings annotation, but the result was same: @RemoteBindings({@RemoteBinding(jndiBinding="ejb/Foobar")}) The bean does not get bound to JNDI with the specified name, and the log file doesn't give any clues.

  • Incremental Backups / Versioned backups using PHP

    - by Adam
    I'm trying to backup a folder containing several folders and files to a remote location (will be uploading zipped files). Is there any existing scripts that may help me, which checks if the files have been modified after the date of the last backup, and only backs up files created / modified after that? The current size of the data is around 1gb, and I expect adding 50mb-200mb each month Also, what would be the best way to extract the state of the files on a specific date?

  • Specify connection timeout in java.nio

    - by miorel
    Using non-blocking I/O, the code for connecting to a remote address looks something like: SocketChannel channel = SelectorProvider.provider().openSocketChannel(); channel.configureBlocking(false); channel.connect(address); The connection process will then have to be finished by invoking finishConnect() on the channel when some selector says the corresponding key isConnectable(). Is there a way to specify the connection timeout when using this idiom?

  • General Questions on setting up Subversion (w/Netbeans) and web development workflow.

    - by Roeland
    Hey guys, I am web developer who currently works mostly on his own but, some projects require outside coding help (my brother.) Anyway, after running in to the problem of "working on the same files" and "saving over each others edits" I decided to research ways to avoid this. Through the help of stackoverflow I decided on subversion. My setup is the following: A windows 2008 server with a clean install. My desktop which is on the local network of the server. Then my brothers desktop which is at his house, not on lan. We both prefer to use netbeans for development. My Questions: How do we set this thing up correctly and most optimally. Here is my current setup and work flow. dev site: in the past I just created sub domains with my web host for test sites (company1.bythepixel.com, company2.bythepixel.com), and editted those sites with netbeans set up having remote sources (ftp). how do i set up my netbeans now? should I set it up with remote sources? I guess I may need to set up a web server on my local server. I'm just not sure of the work flow. When i hit save in netbeans.. will it update the repository.. then do i need to update the site from the repository somehow? live site: when going live, i would just copy all the files from the dev site into the live site. from what i gather i should be able to update the site from the dev repository? Currently I am toying with virtualsvn server (http://www.visualsvn.com/server/) on my local server. It looks like it is set up to use the http protocol. Is there advantages to this or should I consider something that does the file//. Do you recommend any other subversion software that would run on my 2008 box? how will my brother connect? should i set up a permanent vpn from his house to mine? suggestions? (not that important) how do I deal with databases, there anyway to do subversion on database? I know I have a lot of questions and I am trying to read / make sense of the free online subversion book, but its all so overwhelming! Wish there was a small subversion for dummies guide :)

  • Installing a new SQL Server instance fails

    - by Rubio
    I've previously in my setup installed SQL Server Express 2005. Now I've switched to SQL Server Express 2008. I updated the command line parameters to those documented for the latter. If the comp already has SQL Server Express 2008 installed, my installer should create a new instance. The command line parameters are as follows: /ACTION=Install /FEATURES=SQLEngine /QS /INSTANCENAME=ABCD /SECURITYMODE=SQL /SAPWD=CunningPassword The requested instance name does not exist on the target machine. This will end in an error -2068643838. The logs show the following error: "No features were installed during the setup execution. The requested features may already be installed." If I remove the /QS parameter and try to install interactively, I'll get as far as the Feature Selection page. The UI shows three options, Instance Features, Shared Features and Redistributable Features. Whatever I select, clicking Next results in the same error (There are validation errors on this page). Any ideas anyone? Thanks, -- Rubio

  • redoing object model construction to fit with asynchronous data fetching

    - by Andrew Patterson
    I have a modeled a set of objects that correspond with some real world concepts. TradeDrug, GenericDrug, TradePackage, DrugForm Underlying the simple object model I am trying to provide is a complex medical terminology that uses numeric codes to represent relationships and concepts, all accessible via a REST service - I am trying to hide away some of that complexity with an object wrapper. To give a concrete example I can call TradeDrug d = Searcher.FindTradeDrug("Zoloft") or TradeDrug d = new TradeDrug(34) where 34 might be the code for Zoloft. This will consult a remote server to find out some details about Zoloft. I might then call GenericDrug generic = d.EquivalentGeneric() System.Out.WriteLine(generic.ActiveIngredient().Name) in order to get back the generic drug sertraline as an object (again via a background REST call to the remote server that has all these drug details), and then perhaps find its ingredient. This model works fine and is being used in some applications that involve data processing. Recently however I wanted to do a silverlight application that used and displayed these objects. The silverlight environment only allows asynchronous REST/web service calls. I have no problems with how to make the asychhronous calls - but I am having trouble with what the design should be for my object construction. Currently the constructors for my objects do some REST calls sychronously. public TradeDrug(int code) { form = restclient.FetchForm(code) name = restclient.FetchName(code) etc.. } If I have to use async 'events' or 'actions' in order to use the Silverlight web client (I know silverlight can be forced to be a synchronous client but I am interested in asychronous approaches), does anyone have an guidance or best practice for how to structure my objects. I can pass in an action callback to the constructor public TradeDrug(int code, Action<TradeDrug> constructCompleted) { } but this then allows the user to have a TradeDrug object instance before what I want to construct is actually finished. It also doesn't support an 'event' async pattern because the object doesn't exist to add the event to until it is constructed. Extending that approach might be a factory object that itself has an asynchronous interface to objects factory.GetTradeDrugAsync(code, completedaction) or with a GetTradeDrugCompleted event? Does anyone have any recommendations?
