  • Making application listen to port

    - by dplanet
    I am running an Ubuntu guest machine through my Windows 7 host machine (with Virtualbox), and on the Ubuntu system running an application that uses port 6969. Through configuring the Virtualbox port forwarding settings I have made it possible that I can go to 127.0.0.1:6969 in my browser and see the application's default page. However, I'm wondering how I can port forward from my Windows 7 machine to the whole network. My local network (IPv4) address is 192.168.0.5. I want to be able to go to 192.168.0.5:6969 from any computer on the network and see the application. I've searched Google but can only seem to find solutions in Linux, not Windows. How can I do this?

  • Memory Usage by Mapped Files (Win7 64Bit)

    - by Dexter
    When copying files from/to my external USB3 HDD memory usage in Win7 goes up to 100% and remains there. I'm not sure whether this is a problem caused by faulty drivers or not, but I already have the current version of them (Etron USB3 controller on a Gigabyte 990fxa board).. Using RAMMap it becomes obvious that the files, that are to be copied, are mapped into memory. Clicking on Empty > Empty System Working Set seems to temporarily fix the problem (without causing any trouble with the file copy process), but it needs to be done every few seconds. Is there any way to schedule this operation to happen ever 10 or so seconds on its own? What underlying system command is RAMMap using? Or, alternatively, is there any way to limit how much RAM mapped files may use in Windows 7? I know mapped files would usually be removed from memory if other programs need the memmory, but while memmory usage is at 100% the system starts freezing up for half a second or so everytime I click anything .. thus the automatic removal of unused memory contents seems to be failing here.

  • Application isn't showing up in launcher

    - by CaldwellYSR
    So I downloaded eclipse earlier today so I can start to learn the Android SDK. I typically write java programs with vim from the command line but I was having trouble making the sdk work from the command line. Anyways Eclipse was begin weird so I uninstalled it with Synaptic, then I reinstalled. Now it seems to be working fine except I can't get eclipse to show up in the launcher... Is there anything I may be missing that would make the launcher show up?

  • Why might one hard disk perform slower than another?

    - by Styne666
    I have just bought two WD 3TB Reds (WD30EFRX) for a FreeNAS box and whilst doing burn-in testing it seems like one is consistently taking about 10% longer than the other. So far I've done: a dd read test of the whole device, a long SMART test and it's currently halfway through a badblocks -wvs. The second device is lagging behind the first on all of them. I'm running these commands on Debian stable in two Konsole tabs. Is there a reason this could be considered normal behaviour or is it worth running the tests independantly? They're both plugged in to the LSI 2308 (IT mode) on a Supermicro X10SL7-F.

  • Speed up connection to MySQL

    - by Leonick
    So here's one for you. Any idea on a way to shorten the time it takes to connect to a MySQL database? The reason I'm wondering is because I find that just connecting to the DB adds just over a second to the rendering of the page and that seems a bit long considering Apache and MySQL is running on the same machine and the mysqli_connect is connecting to localhost. It's just such a shame when the connection takes a second while any query I end up doing won't add any significant amount of time to the render/load time. Any ways to shorten the time it takes to open a connection?

  • How to create a RAM Drive (RAM Disk) in Windows 2008 R2?

    - by Mark
    There are lots of tools for creating RAM drives. None of them seem to work for windows 2008 R2. Does anyone know if this is possible and if so how. Does anyone know of a tool that does work? I've tried the gavotte ram disk. It doesn't work. When i try to install it it just sais "Failed". I don't see log files anywhere. I've tried a couple of other ones (forgot the names) to no avail. Any ideas? Thanks

  • Asp.net mvc application deployment / security issues

    - by WestDiscGolf
    I'll start with appologies; I wasn't sure if this was best posted here of Server Fault so if its in the wrong place then please move :-) Basic information I have written the first module of a new application at work. This is written using Visual Studio 2010, targetting .net 3.5 (at the moment) and asp.net mvc 2. This has been working fine during development running on the built in Development server from VS but however does not work once deployed to IIS 7/7.5. To deploy the application, I have built it in release mode and created a deployment package by right clicking on the project in the solution explorer (this will be done with an automated build in tfs once upgrade from the beta). This has then been imported into IIS on the server. The application is using windows/domain authentication. Issue #1 I can fire up internet explorer and browse to the application from a client computer as well as on a remote desktop connection. I can execute the code which reads/stores data in Session fine from the IE instance on the remote desktop but if I browse to it from the client pc it seems to lose the session state. I click on the form submit and the page refreshes and doesn't execute the required code. I've tried setting with; InProc, SQLServer and StateServer. but with no luck :-( Issue #2 As part of the application it views PDF and Tiff documents on the fly which are on a network share on the office network and creates thumbnails if the document hasn't been viewed before. This works if running on the machine the application is deployed to; however when browsing from a client pc I get an error saying: Access to the path '\\fileserver\folder\file.tif' is denied Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.UnauthorizedAccessException: Access to the path '\\fileserver\folder\file.TIF' is denied. ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. As this is on a different server the user is not accessible. To get round this I have tried: 1 - setting the application pool to run as domain administrator (I know this is a security risk, but I'm just trying to get it to work at the moment!) 2 - to set the log on account for World Wide Web Publishing service to be the domain admin . When trying to restart the service I get ... Windows could not start the World Wide Web Publishing Service service on the Local Computer. Error 1079: The account specified for this service is different from the account specified fro the other services running in the same process. Any pointers/help would be much appriciated as I'm pulling my hair out (of what little I have left). Update I've been using this funky little tool I found - DelegConfig v2 beta (Delegation / Kerberos Configuration Tool). This has been really usefull. So I've got the accessing of the file share working (there is a test page which will read the files) so now I've just got the issue of passing through the users credentials through to the SQL Server (wans't my choice to do it this way!!) to execute the queries etc. but I can't get it to log on as the user. It tries to access it as "NT Authority\Network Service" which doesn't have a sql login (as should be the logged on user). My connection string is: <add name="User" connectionString="Data Source=.;Integrated Security=True" providerName="System.Data.SqlClient" /> No initial catalog is specified as the system is over multiple dbs (also wasn't my choice!!). I really appriciate all the help so far! :-) Any further hints?!

  • How does Google App Engine precompile Java ?

    - by Thilo
    App Engine uses a "precompilation" process with the Java bytecode of an app to enhance the performance of the app in the Java runtime environment. Precompiled code functions identically to the original bytecode. Is there any detailed information what this does?

  • How do I run my C# application in scheduled tasks when I am not logged in

    - by Peggy A
    I have a C# console application that just processes data. The problem is that when I log off, the console application ends. If I schedule the application to run at a set time and I am not logged in, the application does not run at all. I can run it interactively by double clicking the exe and I can open scheduled tasks and run it by right clicking and selecting run. As soon as I log out, the application ends. Any help will be greatly appreciated.

  • Recommendation for high performance WPF Chart

    - by Ajaxx
    We're working on a WPF-based desktop application that charts financial markets information (candlestick charts, overlayed indicator curves, volume, etc). The charts are displayed in real-time with responses to market ticks being shown in real-time (updating one to two times per second is probably a reasonable display refresh policy). We've been looking for a software package (commercial is fine by us) that has the capability of displaying these charts. Additionally, we'd like to have an approach that can render the initial amount of data in a reasonable timeframe (give or take 100-200ms from the time we hand the data over to a complete render on screen). Also we view multiple charts (5-10) simultaneously so a solution that chews up 50% of my CPU to display one chart really isn't going to work well. Has anyone had any good experiences with charting controls. We've had to hand roll the last few charts we've done and I'd prefer not to do it again. Solutions that can make use of the GPU to minimize CPU utilization would be nice as well.

  • Cocoa Application with Menubar but no Dock Icon / switch menu

    - by Frank R.
    Hi, This is yet one more of those "how to switch from running with a dock icon to running without one" questions with a twist.. I don't want the dock icon but I do want a menu bar when the application is at the front. Is that possible? Running an application with LSUIElement set to 1 in the plist will launch the application without a dock icon, not showing up in the command-tab switch list and without a menu. You can switch from that mode to the "normal" mode with all three switched on via SetSystemModeUI from 10.2 onwards and via NSApplication setApplicationActivationPolicy since 10.6, but crucially there is no way back to the previous mode (go figure). So one way around this would be to launch with LSUIElement = 1 and then activate the menu bar when the application gets the focus and deactivate it on the application losing the focus.. alas I can't find a way of doing that. Can anybody help? Best regards, Frank

  • javamail vs sendmail performance during bulk email

    - by Glenn2041
    Hi all, I'm writing a Java mass emailer application to send out emails to send between 50,000 to 100,000 a day to users. The current plan is to delegate the sending to delegate to sendmail (on the local unix server). From our testing sendmail is sending a maximum of 5 emails per second. Would JavaMail be a faster option? Does anyone know what a faster way to send emails. We want to get this process out as quick as possible. Edit: BTW, a pdf will be attached too

  • How to increase the startup speed of the delphi app?

    - by Olaf
    What do you do to increase startup speed (or to decrease startup time) of your Delphi app? Other than application specific, is there a standard trick that always works? Note: I'm not talking about fast algorithms or the likes. Only the performance increase at startup, in terms of speed.

  • Struts 1 - struts-taglib.jar is not being found by my web application

    - by Yatendra Goel
    I am using Struts-1. I have developed a struts-based web application. I am using struts tags in my JSP pages supplied in struts-taglib.jar by inserting the following lines in the JSP file: <%@ taglib prefix="html" uri="http://struts.apache.org/tags-html" %> <%@ taglib prefix="logic" uri="http://struts.apache.org/tags-logic" %> <%@ taglib prefix="bean" uri="http://struts.apache.org/tags-bean" %> Now the application is working fine when I run it on my localsystem but when I deploy it on a server, it shows the following exception: org.apache.jasper.JasperException: The absolute uri: http://struts.apache.org/tags-html cannot be resolved in either web.xml or the jar files deployed with this application From the above exception, it seems that the application hasn't found the struts-taglib.jar file. But I have put the struts-taglib.jar in /WEB-INF/lib directory. Then where is the problem? Note: You can also look at http://stackoverflow.com/questions/2452492/java-problem-in-deploying-web-application for more information
