  • Creating image of NTFS partition in Ubuntu

    - by Pappai
    Hi, I have a system that has to be formatted often because of the specific use of it (Use it in internet cafe). I have to install the drivers and apps each time. That is a time consuming and cumbersom task for me. I want to install windows, drivers, apps etc. once and create a backup of the entire C:\ drive, and keep it in a linux partition so that I can restore the OS with all the apps & drivers ready to go! I have ubuntu live CD with me and I have created a linux partition (ext4) in the HDD. My question is: How can I create an image of the C:\ drive (ntfs disk) in Ubuntu and store it in the linux partition?

  • rsync generates very much traffic

    - by user109459
    I use rsync for backing up one of my servers with 4GB of files. When I now try to transfer these files the traffic for the files isn't the estimated 4GB. It is a lot higher. It's about 60GB. I also checked the traffic on my server, backup server and router and all three say that there was a traffic of 60GB. But at the end rsync says that it only has transfered 4GB. Another problem is that I can't debugg it because the problem occures randomly.

  • Nightly backups (and maybe other tasks) causing server alerts

    - by J. Pablo Fernández
    I have two independent alert notification systems for my servers. The server is a virtual machine on Linode and one of the alerts comes from Linode. The other monitoring system we use is New Relic. They are both watching out for IO utilization. Every night I get alerts from both of them as the server is using too much IO. I run quite a few tasks in the middle of the night but the one I confirmed that can cause IO-warnings is running the backups. The backup is done by s3cmd sync. I tried ionice but it still generates the warnings. Getting warnings every night reduces the efficacy of warnings when they happen for real. For Linode I could raise the level at which a warning is issued, but it might mean making the whole thing useless as the level is too high. What would be the proper solution for this?

  • Should the virtualization host be allowed to run any service?

    - by Giordano
    I recently setup a virtualization server for the small company I'm running. This server runs few virtual machines that are used for development, testing, etc... My business partner works from a remote location, thus I also installed a vpn server on the virtualization host to make it possible for him to safely reach the company services. Moreover, again on the virtualization host, I installed bacula to perform the backup of the data. Is it advisable/good practice to do so or should I create one more virtual machine to do backups and VPN? Is it a bad idea to run these services on the host itself? If yes, why? Thanks in advance!

  • Back up Linux environment

    - by joesavage
    I'm currently in the process of installing a bunch of stuff I need and getting setup my Linode that I recently purchased. Being a Linux newbie, I'm doing pretty well - but one small mistake can screw everything up for me. I've currently got apache2 and some other things successfully installed and setup how I want them, and DO NOT want this to be ruined by some newbie mistake. What is the easiest way to backup the actual environment itself so that I can restore the backed up environment (with apache2 and things fully working) if I mess up?

  • tar gzip slowing down server

    - by Josir
    I have a backup script that: compress some files generate md5 copy the compressed file to another server. the other server finishes comparing MD5 (to find copy errors). Here it's the core script: nice -n 15 tar -czvf $BKP $PATH_BKP/*.* \ | xargs -I '{}' sh -c "test -f '{}' && md5sum '{}'" \ | tee $MD5 scp -l 80000 $BKP $SCP_BKP scp $MD5 $SCP_BKP This routine got CPU at 90% at gzip routine, slowing down the production server. I tried to add a nice -n 15 but server still hangs. I've already read 1 but the conversation didn't help me. What is the best approach to solve this issue ? I am open to new architectures/solutions :)

  • Settings what-opens-what once and for all (Backing up File Associations)

    - by ldigas
    Every time I switch machines (as in, get a new one, or reinstall an OS or something like that) my precious file associations get lost. And the next six months pass slowly until I again set them up right. Is there a program that allows me to: Set all the extensions I would like to open with let's say, Vim, without setting each one of them individually. Something of a kind: Vim opens: .... list of extensions ... and/or A program which lets me backup my current settings, and when I copy those to a new machine it lets me just modify the paths where I putted the applications in question, and it does the rest (again, associates that program with all the extensions it opened before).

  • Why is Ubuntu One slow to sync in 11.10, either backup or any sub-folder contents?

    - by pst007x
    I have been trying to sync my documents folder of 1.4GB, it still hasn't worked and it has been syncing for a month. The top level syncs, files and folders in the Document folders, but contents of sub-folders just hang. (Gave up and stopped syncing this folder) However,I have tried using the backup facility in 11.10, to backup to Ubuntu One.... I upgraded my HDD space in Ubuntu One. It has been going now for 24hours-ish and only backed up what looks like a couple of percent. (By the way what an excellent idea to backup to Ubuntu One, if only we could get it to actually work! :-o) The odd thing is I can sync to drop box within hours, rather than months. This is bad, and has been an issue since Ubuntu One's release. I have reported this problem and there were promises in later releases this would be fixed, but it hasn't. Canonical cannot help either... I posted on several blogs, a lot of people have the same problem but no fixes. So do I use dropbox or another service, until it is sorted, as Ubuntu does not seem to see this as an issue, I think a fix will be a long time in coming. (However,I love the potential of Ubuntu One and the integration with the OS) Yes my internet speeds are fine, etc... :-) No firewall (sudo ufw status: STATUS: INACTIVE), No Proxy, etc NB: I have raised this as a separate question to others posted here, because my question relates to Ubuntu 11.10, though I have commented elsewhere for help. Plus my question also relates to deja-dup backup to Ubuntu One. Thanks

  • PathTooLongException after migrating from ASP.NET MVC 1 to ASP.NET MVC 2

  • Weird - "The EntityReference object could not be serialized" when serializing from an ASP.NET Web Si

    - by Mikey Cee
    I have an Entity Framework data model. Part of the model is a Customer entity. The web service provides a method to get a customer, and to receive an updated version of this customer to be persisted. To test this, I created a new ASP.NET web Application, (Solution Add New Project ASP.NET Web Application), then added a reference to my service reference using the standard Add Service Reference dialog. I then call the service using the following code: var client = new CustomerServiceClient(); var customer = client.GetCustomerByID(18); // get it customer.LimitDown = 100; // change it client.SaveCustomer(customer); // persist it Everything works as expected. Now, I do exactly the same thing, but this time with as ASP.NET Web Site (Solution Add New Web Site ASP.NET Web Site). I add the reference in a similar fashion and copy and paste the code above into the new site. But now I get the following exception thrown on the 4th line: System.InvalidOperationException The EntityReference object could not be serialized. This type of object cannot be serialized when the RelationshipManager belongs to an entity object that does not implement IEntityWithRelationships. Source Error: Line 2474: Line 2475: public SkyWalkerCustomerService.OperationResult SaveCustomer(SkyWalkerCustomerService.Customer customer) { Line 2476: return base.Channel.SaveCustomer(customer); Line 2477: } Line 2478: } Stack Trace: System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) +9475203 System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) +345 SkyWalkerCustomerService.ICustomerService.SaveCustomer(Customer customer) +0 SkyWalkerCustomerService.CustomerServiceClient.SaveCustomer(Customer customer) in c:\Windows\Microsoft.NET\Framework\v4.0.30128\Temporary ASP.NET Files\testsite2\dd2bcf8d\f95604ff\App_WebReferences.fz4h7x7l.0.cs:2476 _Default.Page_Load(Object sender, EventArgs e) in c:\Users\Mike\Documents\Repositories\UWC\SkyWalker\TestSite2\Default.aspx.cs:17 System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) +14 System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) +35 System.Web.UI.Control.OnLoad(EventArgs e) +91 System.Web.UI.Control.LoadRecursive() +61 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1966 Googling for this error returns very little.

  • "Best" language /architecture for browser-based app with ODBC and sockets? (subjective)

    - by mawg
    Sorry to ask a subjective question, but I would welcome some advice. I am an experienced programmer of embedded s/w, but haven't done much network programming, although I have done a fair bit of hobbyist PHP. Anyway, I have to develop what is probably a fairly general type of app, as shown in this crude diagram --------------------------------------------------------------------------------- | Browser / user interface Takes input from user form and writes data to d/b. | | Also gets data and updates browser contents when when d/b contents are changed | | because of info received over TCP/IP. | |________________________________________________________________________________| | ODBC | |_______________________________________________________________________________| | database | |_______________________________________________________________________________| | ODBC | |_______________________________________________________________________________| | Socket (TCP/IP) | | Send data out when d/b is updated from browser. | | Also, update d/b when data are received over TCP/IP. | |_______________________________________________________________________________| As I say, I imagine this to be a fairly typical architecture? Am I right? Then client is insisting on MSIE - unless I can show compelling technical reasons for FireFox or other then it will have to be MSIE (are there any compelling technical reasons?). So, with MIE (almost) a given, I had though to use PHP, since I know it, but the client seems awfully keen on Java (which ought to be OK since I am conversant with C++) it woudl seem to make sense to use the same language for the "upper" interface between the web pages (which that app generates) and the d/b, and for the "lower" interface between the d/b and the socket. (a single language means a single set of tools since text approach, etc) So, the (probably highly subjective) question is "which language shoudl I choose". As I say, the client is keen on Java. Any compelling reason why not? Is it generally a good choice for the sort of thing described here? Any other hints & tips gratefully appreciated (and up-voted): URLs, books, tool chain suggestions, etc, etc

  • Ninject woes... 404 error problems

    - by jbarker7
    We are using the beloved Ninject+Ninject.Web.Mvc with MVC 2 and are running into some problems. Specifically dealing with 404 errors. We have a logging service that logs 500 errors and records them. Everything is chugging along just perfectly except for when we attempt to enter a non-existent controller. Instead of getting the desired 404 we end up with a 500 error: Cannot be null Parameter name: service [ArgumentNullException: Cannot be null Parameter name: service] Ninject.ResolutionExtensions.GetResolutionIterator(IResolutionRoot root, Type service, Func`2 constraint, IEnumerable`1 parameters, Boolean isOptional) +188 Ninject.ResolutionExtensions.TryGet(IResolutionRoot root, Type service, IParameter[] parameters) +15 Ninject.Web.Mvc.NinjectControllerFactory.GetControllerInstance(RequestContext requestContext, Type controllerType) +36 System.Web.Mvc.DefaultControllerFactory.CreateController(RequestContext requestContext, String controllerName) +68 System.Web.Mvc.MvcHandler.ProcessRequestInit(HttpContextBase httpContext, IController& controller, IControllerFactory& factory) +118 System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContextBase httpContext, AsyncCallback callback, Object state) +46 System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContext httpContext, AsyncCallback callback, Object state) +63 System.Web.Mvc.MvcHandler.System.Web.IHttpAsyncHandler.BeginProcessRequest(HttpContext context, AsyncCallback cb, Object extraData) +13 System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +8679426 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +155 I did some searching and found some similar issues, but those 404 issues seem to be unrelated. Any help here would be great. Thanks! Josh

    I had a powerbuilder application which i converted to web application in the format of ASP.Net (aspx) files. after deploying and publishing the converted web application (copy it and add ASP.Net and network Service AND IUser permissions to enable users to access it) in IIS V6.0 over Windows server 2003 and The ASP.Net version is 2.0 The error messages I get when I browse default.aspx web page are as the following:- Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". <!-- Web.Config Configuration File --> <configuration> <system.web> <customErrors mode="Off"/> </system.web> </configuration> Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL. <!-- Web.Config Configuration File --> <configuration> <system.web> <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/> </system.web> </configuration> Another error message appears on the server is:- Server Error in '/' Application.

  • Enable Automatic Code First Migrations On SQL Database in Azure Web Sites

    - by Steve Michelotti
    Now that Azure supports .NET Framework 4.5, you can use all the latest and greatest available features. A common scenario is to be able to use Entity Framework Code First Migrations with a SQL Database in Azure. Prior to Code First Migrations, Entity Framework provided database initializers. While convenient for demos and prototypes, database initializers weren’t useful for much beyond that because, if you delete and re-create your entire database when the schema changes, you lose all of your operational data. This is the void that Migrations are meant to fill. For example, if you add a column to your model, Migrations will alter the database to add the column rather than blowing away the entire database and re-creating it from scratch. Azure is becoming increasingly easier to use – especially with features like Azure Web Sites. Being able to use Entity Framework Migrations in Azure makes deployment easier than ever. In this blog post, I’ll walk through enabling Automatic Code First Migrations on Azure. I’ll use the Simple Membership provider for my example. First, we’ll create a new Azure Web site called “migrationstest” including creating a new SQL Database along with it:   Next we’ll go to the web site and download the publish profile:   In the meantime, we’ve created a new MVC 4 website in Visual Studio 2012 using the “Internet Application” template. This template is automatically configured to use the Simple Membership provider. We’ll do our initial Publish to Azure by right-clicking our project and selecting “Publish…”. From the “Publish Web” dialog, we’ll import the publish profile that we downloaded in the previous step:   Once the site is published, we’ll just click the “Register” link from the default site. Since the AccountController is decorated with the [InitializeSimpleMembership] attribute, the initializer will be called and the initial database is created.   We can verify this by connecting to our SQL Database on Azure with SQL Management Studio (after making sure that our local IP address is added to the list of Allowed IP Addresses in Azure): One interesting note is that these tables got created with the default Entity Framework initializer – which is to create the database if it doesn’t already exist. However, our database did already exist! This is because there is a new feature of Entity Framework 5 where Code First will add tables to an existing database as long as the target database doesn’t contain any of the tables from the model. At this point, it’s time to enable Migrations. We’ll open the Package Manger Console and execute the command: PM> Enable-Migrations -EnableAutomaticMigrations This will enable automatic migrations for our project. Because we used the "-EnableAutomaticMigrations” switch, it will create our Configuration class with a constructor that sets the AutomaticMigrationsEnabled property set to true: 1: public Configuration() 2: { 3: AutomaticMigrationsEnabled = true; 4: } We’ll now add our initial migration: PM> Add-Migration Initial This will create a migration class call “Initial” that contains the entire model. But we need to remove all of this code because our database already exists so we are just left with empty Up() and Down() methods. 1: public partial class Initial : DbMigration 2: { 3: public override void Up() 4: { 5: } 6: 7: public override void Down() 8: { 9: } 10: } If we don’t remove this code, we’ll get an exception the first time we attempt to run migrations that tells us: “There is already an object named 'UserProfile' in the database”. This blog post by Julie Lerman fully describes this scenario (i.e., enabling migrations on an existing database). Our next step is to add the Entity Framework initializer that will automatically use Migrations to update the database to the latest version. We will add these 2 lines of code to the Application_Start of the Global.asax: 1: Database.SetInitializer(new MigrateDatabaseToLatestVersion<UsersContext, Configuration>()); 2: new UsersContext().Database.Initialize(false); Note the Initialize() call will force the initializer to run if it has not been run before. At this point, we can publish again to make sure everything is still working as we are expecting. This time we’re going to specify in our publish profile that Code First Migrations should be executed:   Once we have re-published we can once again navigate to the Register page. At this point the database has not been changed but Migrations is now enabled on our SQL Database in Azure. We can now customize our model. Let’s add 2 new properties to the UserProfile class – Email and DateOfBirth: 1: [Table("UserProfile")] 2: public class UserProfile 3: { 4: [Key] 5: [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)] 6: public int UserId { get; set; } 7: public string UserName { get; set; } 8: public string Email { get; set; } 9: public DateTime DateOfBirth { get; set; } 10: } At this point all we need to do is simply re-publish. We’ll once again navigate to the Registration page and, because we had Automatic Migrations enabled, the database has been altered (*not* recreated) to add our 2 new columns. We can verify this by once again looking at SQL Management Studio:   Automatic Migrations provide a quick and easy way to keep your database in sync with your model without the worry of having to re-create your entire database and lose data. With Azure Web Sites you can set up automatic deployment with Git or TFS and automate the entire process to make it dead simple.

  • REST Framework - MS Web Api vs the rest of the field

    - by Mike
    I am a .NET developer who is looking into the OSS world for a REST framework similar to Microsoft's Web Api. I'll be starting a personal project soon and need to develop both a web site and an API with the API coming first. I've ruled out Ruby on Rails just because I feel that with my background in C#, I can get up to speed quickly with either a Java or PHP based framework. So far I've looked at Slim (PHP) and JAX-RS and Jersey (Java). Would I want to consider any others? My API will be private at first with a public one on the roadmap. I'll be hosting the API on Heroku or some cloud based service.

  • How can I show ads for search on own web site

    - by user3826
    On my web site there is a (self-coded) search functionality that searches through the web site's specific contents. However I'd like to display one banner in addition to the site's results, showing ads relevant to the entered search terms. Can I do this e.g. with Google Ads? I want the ads to be based only on the search terms from the user, not the rest of the site's content, so there has to be a possibility to pass these search terms to the ad provider and get a banner based on these search terms.

  • Best format for backing up data in Blu Ray

    - by Arrieta
    We are in the process of backing up our hard drives to Blu Rays. I am creating tar.gz files and burning them to Blu Ray. Is it possible to use a simple (preferably Python-based) solution for creating images of those tar.gz files, of a predetermined size (to fit in the Blu Ray), and simply burn this images to the disc? Do you have any other approach for creating physical back-up of your hard drives?

  • AGPL License - does it apply in this scanerio?

    - by user1645310
    There is an AGPLv3 based software (Client) that makes web service calls (using SOAP) to another software (Server - commercial, cloud based). There is no common code or any connection whatsoever between these two except for the web service calls being made. My questions - Does the Server need to be AGPL too? I guess not - but would like to confirm. Let us say the end point URL for the Server can be configured on the Client side (by editing an XML file) to connect it to different Servers (again, there is no connection other than the webservice calls being made) does it require any of these Servers being AGPL? Are there any issues in running the Client as a DLL that is loaded by other commercial applications on users' desktops? Does it require these other applications also to be AGPL? Appreciate your quick response. Pluto!

  • Does using structure data semantic LocalBusiness schema markup work for local EMD URL's?

    - by ElHaix
    Based on what I have read about Google's recent Panda and Penguin updates, I'm getting the impression that using semantic markup may help improve SEO results. On a EMD (exact match domain) site, that may have been hit, we list location-based products. We are now going to be adding a itemtype="http://schema.org/Product" to each product, with relevant details. However, that product may be available in Los Angeles and also in appear in a Seattle results page. We could add a LocalBusiness item type on each geo page to define the geo location for that page. While the definition states: A particular physical business or branch of an organization. Examples of LocalBusiness include a restaurant, a particular branch of a restaurant chain, a branch of a bank, a medical practice, a club, a bowling alley, etc. We could add use the location property which would simply include the city/state details. I realize that this looks like it is meant for a physical location, however could this be done without seeming black-hat?

  • Sharepoint 2010 as framework for website?

    - by Kenny Bones
    So I'm looking at several solutions for our new website. And we've looked at ExpressionEngine first and foremost. Now, during brainstorming today, one person said "why don't we use Sharepoint 2010 to build the site on?", and it doesn't seem like a horrible idea. I mean, we're based around Office anyway. We use Lync and have an intranet based on Sharepoint 2010 anyway. Does anyone have any thoughts on this? Would it cost more to develop an internet webpage on Sharepoint 2010 opposed to using ExpressionEngine?
