  • Why is Samba Access from Windows So Slow?

    - by swalker2001
    I have set up a file server using Ubuntu 12.04 Server. The purpose is to serve several network drives to Windows users that have heretofore been served by numerous NAS drives. I have Samba set up with one share defined so far. I can connect to it fine from my test Windows 7 and Windows XP machines. When I do a directory listing on the share from Windows, it can take up to two minutes to get all the files listed--would have taken about 1.5 seconds when I was using the Buffalo NAS. Sometimes it times out with no response at all. I have used the default smb.conf and simply added the following for the share I have set up so far: [engineering] comment = Ubuntu File Server Share path = /networkdriveshares/engineering browsable = yes guest ok = yes read only = no create mask = 0755 I have tried changing the workgroup setting to the Active Domain name our Windows computer use but didn't notice any difference. The only other change I made to the default smb.conf was adding in the recommended socket settings: SO_RCVBUF=8192 SO_SNDBUF=8192 socket options = TCP_NODELAY Lots of information about slow Samba shares online but I have tried all of the solutions I have found and none have made a lick of difference. If there is no solution, is there a better way to set up a file server to be used by Windows clients?

  • blurry lines between web application context layer, service layer and data access layer in spring

    - by thenaglecode
    I Originally asked this question in SO but on advice I have moved the question here... I'll admit I'm a spring newbie, but you can correct me if I'm wrong, this one liner looks kinda fishy in a best practices sort of way: @RepositoryRestResource(collectionResourceRel="people"...) public interface PersonRepository extends PagingAndSortingRepository<Person, Long> For those who are unaware, the following does many things: It is an interface definition that can be registered in an application context as a jpa repository, automagically hooking up all the default CRUD operations within a persistence context (that is externally configured). and also configures default controller/request-mapping/handler functionality at the namespace "/people" relative to your configured dispatcher servlet-mapping. Here's my point. I just crossed 3 conceptual layers with one line of code! this feels against my seperation-of-concern instincts but i wanted to hear your opinion. And for the sake of being on a question and answer site, I would like to know whether there is a better way of seperating these different layers - Service, Data, Controllers - whilst maintaining as minimal configuration as possible

  • Unable to access A class variables in B Class - Unity-Monodevelop

    - by Syed
    I have made a class including variables in Monodevelop which is: public class GridInfo : MonoBehaviour { public float initPosX; public float initPosY; public bool inUse; public int f; public int g; public int h; public GridInfo parent; public int y,x; } Now I am using its class variable in another class, Map.cs which is: public class Map : MonoBehaviour { public static GridInfo[,] Tile = new GridInfo[17, 23]; void Start() { Tile[0,0].initPosX = initPosX; //Line 49 } } Iam not getting any error on runtime, but when I play in unity it is giving me error NullReferenceException: Object reference not set to an instance of an object Map.Start () (at Assets/Scripts/Map.cs:49) I am not inserting this script in any gameobject, as Map.cs will make a GridInfo type array, I have also tried using variables using GetComponent, where is the problem ?

  • Access Violation when trying to bind Vertex Object Array

    - by Paul
    I've just started digging into OpenGL and I've run into a problem trying to set a VOA. It's giving me a run-time error of : An unhandled exception of type 'System.AccessViolationException' At // Create and bind a VAO GLuint vao; glGenVertexArrays(1, &vao); glBindVertexArray(vao); I have searched the internet high and low for a solution and I haven't found one. The rest of my function looks like this: int main(array<System::String ^> ^args) { // Initialise GLFW if( !glfwInit() ) { fprintf( stderr, "Failed to initialize GLFW\n" ); return -1; } glfwOpenWindowHint(GLFW_FSAA_SAMPLES, 0); // 4x antialiasing glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3); // We want OpenGL 3.3 glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 3); glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); //We don't want the old OpenGL // Open a window and create its OpenGL context if( !glfwOpenWindow( 800, 600, 0,0,0,0, 32,0, GLFW_WINDOW ) ) { fprintf( stderr, "Failed to open GLFW window\n" ); glfwTerminate(); return -1; } // Initialize GLEW if (glewInit() != GLEW_OK) { fprintf(stderr, "Failed to initialize GLEW\n"); return -1; } glfwSetWindowTitle( "Game Engine" ); // Create and bind a VAO GLuint vao; glGenVertexArrays(1, &vao); glBindVertexArray(vao); glfwEnable( GLFW_STICKY_KEYS );

  • [Java2D] Is this bad practice? Multiple Graphics2D Objects

    - by m00st
    I've created a JPanel canvas that holds all graphics; namely JLabel. To get animated sprites to work you have to over ride the paintComponent of the extended JLabel class. I've successfully implemented animated sprites this way. Is it bad practice to have a Graphics2D canvas and then have multiple 'images' in their own Graphics2D?

  • How to keep AST for feature access?

    - by greenoldman
    Consider such code (let's say it is C++) Foo::Bar.get().X How one should keep the AST for this -- as "tree" with root at left Foo(Bar(get(X)), or with root at right (((Foo)Bar)get)X? Or maybe as a flat structure (list)? The first one seems more convenient when resolving names, the second when working with it as expression. I set tag parsing but I am asking from semantic analysis POV really (there is no such tag).

  • One click access to bookmarked files?

    - by dunderhead
    On my Windows machine with just one click I can launch favourite or bookmarked files that I use on a daily basis, which is a great time-saver. Is there any way to do this with 11.10 Unity? Ideally I would like to right-click on an icon in the launcher and have a list of files appear that I could then left-click to launch, but I'd be happy for any simple solution. Please note that I am not referring to recently used files lists - these do not work at all because the bookmarked file will always drop off the bottom of any recently used file list.

  • Google Bot trying to access my web app's sitemap

    - by geekrutherford
    Interesting find today...   I was perusing the event log on our web server today for any unexpected ASP.NET exceptions/errors. Found the following:   Exception information: Exception type: HttpException Exception message: Path '/builder/builder.sitemap' is forbidden. Request information: Request URL: https://www.bondwave.com:443/builder/builder.sitemap Request path: /builder/builder.sitemap User host address: 66.249.71.247 User: Is authenticated: False Authentication Type: Thread account name: NT AUTHORITY\NETWORK SERVICE   At first I thought this was maybe an attempt by a hacker to mess with the sitemap. Using a handy web site (www.network-tools.com) I did a lookup on the IP address and found it was a Google bot trying to crawl the application. In this case, I would expect an exception or 403 since the site requires authentication anyway.

  • Current trends in Random Access Memory

    - by Nutel
    As I know for now because of laws of Physics there will be not any tangible improvements in CPU cycles per second for the nearest future. However because of Von Neumann bottleneck it seems to not be an issue for non-server applications. So what about RAM, is there any upcoming technologies that promise to improve memory speed or we are stack with the current situation till quantum computers will come out from labs?

  • Access Control Service: Transitioning between Active and Passive Scenarios

    - by Your DisplayName here!
    As I mentioned in my last post, ACS features a number of ways to transition between protocol and token types. One not so widely known transition is between passive sign ins (browser) and active service consumers. Let’s see how this works. We all know the usual WS-Federation handshake via passive redirect. But ACS also allows driving the sign in process yourself via specially crafted WS-Federation query strings. So you can use the following URL to sign in using LiveID via ACS. ACS will then redirect back to the registered reply URL in your application: GET /login.srf?   wa=wsignin1.0&   wtrealm=https%3a%2f%2faccesscontrol.windows.net%2f&   wreply=https%3a%2f%2fleastprivilege.accesscontrol.windows.net%3a443%2fv2%2fwsfederation&   wp=MBI_FED_SSL&   wctx=pr%3dwsfederation%26rm%3dhttps%253a%252f%252froadie%252facs2rp%252frest%252f The wsfederation bit in the wctx parameter indicates, that the response to the token request will be transmitted back to the relying party via a POST. So far so good – but how can an active client receive that token now? ACS knows an alternative way to send the token request response. Instead of doing the redirect back to the RP, it emits a page that in turn echoes the token response using JavaScript’s window.external.notify. The URL would look like this: GET /login.srf?   wa=wsignin1.0&   wtrealm=https%3a%2f%2faccesscontrol.windows.net%2f&   wreply=https%3a%2f%2fleastprivilege.accesscontrol.windows.net%3a443%2fv2%2fwsfederation&   wp=MBI_FED_SSL&   wctx=pr%3djavascriptnotify%26rm%3dhttps%253a%252f%252froadie%252facs2rp%252frest%252f ACS would then render a page that contains the following script block: <script type="text/javascript">     try{         window.external.Notify('token_response');     }     catch(err){         alert("Error ACS50021: windows.external.Notify is not registered.");     } </script> Whereas token_response is a JSON encoded string with the following format: {   "appliesTo":"...",   "context":null,   "created":123,   "expires":123,   "securityToken":"...",   "tokenType":"..." } OK – so how does this all come together now? As an active client (Silverlight, WPF, WP7, WinForms etc). application, you would host a browser control and use the above URL to trigger the right series of redirects. All the browser controls support one way or the other to register a callback whenever the window.external.notify function is called. This way you get the JSON string from ACS back into the hosting application – and voila you have the security token. When you selected the SWT token format in ACS – you can use that token e.g. for REST services. When you have selected SAML, you can use the token e.g. for SOAP services. In the next post I will show how to retrieve these URLs from ACS and a practical example using WPF.

  • Access Control Service: Home Realm Discovery (HRD) Gotcha

    - by Your DisplayName here!
    I really like ACS2. One feature that is very useful is home realm discovery. ACS provides a Nascar style list as well as discovery based on email addresses. You can take control of the home realm selection process yourself by downloading the JSON feed or by manually setting the home realm parameter. Plenty of options – the only option missing is turning it off… In other words, when you setup your ACS namespace and realm and register identity provider, there is no way to keep the list of identity providers secret. An interested “user” can always retrieve all registered identity provider (using the browser or download the JSON feed). This may not be an issue with web identity providers, but when you use ACS to federate with customers or business partners, you maybe don’t want to disclose that list to the public (or to other customers). This is an adoption blocker for certain situations. I hope this feature will be added soon. In addition I would also like to see a feature I call “home realm aliases”. Some random string that I can use as a whr parameter instead of using the real issuer URI.

  • Controlling access to site folders if you cannot user Roles

    - by DavidMadden
    I find myself on an assignment where I could not use System.Web.Security.Roles.  That meant that I could not use Visual Studio's Website | ASP.NET Configuration.  I had to go about things another way.  The clues were in these two websites:http://www.csharpaspnetarticles.com/2009/02/formsauthentication-ticket-roles-aspnet.htmlhttp://msdn.microsoft.com/en-us/library/b6x6shw7(v=VS.71).aspxhttp://msdn.microsoft.com/en-us/library/b6x6shw7(v=VS.71).aspxYou can set in your web.config the restrictions on folders without having to set the restrictions in multiple folders through their own web.config file.  In my main default.aspx file in my protected subfolder off my main site, I did the following code due to MultiFormAuthentication (MFA) providing the security to this point:        string role = string.Empty;         if (((Login)Session["Login"]).UserLevelID > 3)         {             role = "PowerUser";         }         else         {             role = "Newbie";         }         FormsAuthenticationTicket ticket =  new FormsAuthenticationTicket( 1,                 ((Login)Session["Login"]).UserID,                 DateTime.Now,                 DateTime.Now.AddMinutes(20),                 false,                 role,                 FormsAuthentication.FormsCookiePath);         string hashCookies = FormsAuthentication.Encrypt(ticket);         HttpCookie cookie =  new HttpCookie(FormsAuthentication.FormsCookieName, hashCookies);         Response.Cookies.Add(cookie); This all gave me the ability to change restrictions on folders without having to restart the website or having to do any hard coding.

    I've read through the discussion here... http://stackoverflow.com/questions/273516/how-do-you-implement-a-good-profanity-filter I've decided to implement a bad word filter using the badlist referenced in that thread. However I'm thinking about the scunthorpe problem. (see wikipedia I can't post the link, I'm a new user) Is there a white list of words like scunthorpe and manuscript that I can use to override a black list?

  • Business layer access to the data layer

    - by rerun
    I have a Business layer (BL) and a Data layer (DL). I have an object o with a child objects collection of Type C. I would like to provide a semantics like the following o.Children.Add("info"). In the BL I would like to have a static CLASS that all of business layer classes uses to get a reference to the current datalayer instance. Is there any issue with that or must I use the factory pattern to limit creation to A class in the BL that knows the DL instance.
