  • How do I install latest NVIDIA drivers from the .run file?

    - by Shahe Tajiryan
    This is what I am trying to do. I downloaded the latest driver for my VGA from http://www.nvidia.com. The installation needs the X11 to be shut down, so I log out of my account, then press CTRL+ALT+F1, then log in with my username and password, then run the command sh NVIDIA-Linux-x86_64-285.05.09.run in every possible way, I have even tried CHMODing the package with 777 permissions, but still I'm getting the sh: can't open NVIDIA-Linux-x86_64-285.05.09.run error. Any help would be greatly appreciated.

  • Designing a hierarchical structure with lots of reads and writes?

    - by JD01
    I am in the process of working on a video on demand system part of it involves the management of a hierarchical tree structure (think windows explorer) which allows users to upload videos, move folders around, create new folders etc. User action will be allowed depending on which permissions they have. In addition to managing the structure (creating folders and uploading videos), subscribers will be viewing content (read access). The number of reads will be significantly more than the writes. My question (and it is big one) is should I store the data in a database (for the writes) and also have some sort of cache which will be used for the reads? or do I use two databases? or is there a better solution? Also I will have to resolve concurrency issues which I think optimistic locking on the database will resolve. I have a fair bit about CQRS over the last few months but not sure if this is the way to go. Any ideas?

  • How to setup complete file access and control on a network

    - by user96270
    I have a media server running ubuntu 12.04 and I want it setup so that any PC on the network (windows etc) has complete access to all files, folders etc with read, write, edit, copy to, copy from permissions. No need for security (IE no password or user name, just select it on the network and start editing). I have samba installed and personal file sharing is enabled but my windows PC cannot see it on the network. I already set up another server as I described but unfortunately I can't remember how or where I found the guides for it. Any on know of a guide that covers what I want?

  • A Safe Way to Allow Upload of All File Types?

    - by user34682
    By default WordPress restricts the file types that can be uploaded to /uploads using the default Media Manager. I know it is possible to manually extend the allowed file types. I also know it is possible to change functions.php to allow ALL file types to be uploaded. This restriction obviously exists for security concerns - e.g. someone could upload a harmful .exe Would it not be possible to allow secure upload of all filetypes by setting the permissions of the /uploads directory to prevent execution of any of its contents? Thus it wouldn't matter if someone uploaded a harmful file because it would not be executable on the server...

  • Fedora 16 can connect to samba share using smbclient but not in nautilus 3.2.1

    - by Nathan Jones
    I have a machine running Ubuntu 11.10 Server acting as a Samba server to share my home directory. Everything works fine on my Windows 7 machine, but on my Fedora 16 laptop, if I use Nautilus to try to access the share using smb://192.168.0.8/nathan in the location bar, it just has the loading cursor and does nothing. It never shows any errors, nothing. Using smbclient works just fine, but I'd like to get it working in Nautilus. I know that there can be problems with SELinux and Samba, so I created a file called booleans.local that contains samba_enable_home_dirs=1.

  • 'Could not find RubyGem bundler', even though it is…

    - by ashleyw
    I'm running Ruby 1.9.2preview1 (via RVM), and Bundler 0.9.18. If I execute bundle install, it works fine until the point where I don't have the correct permissions to install a gem. However if I execute sudo bundle install, it spits out that it 'Could not find RubyGem bundler'. How can this be, why is the behaviour changing when using sudo? Thanks

  • C# remote web request certificate error

    - by Ben
    Hi. I am currently integrating a payment gateway into an application. Following a successful transaction the remote payment gateway posts details of the transaction back to my application (ITN). It posts to a HttpHandler that is used to read and validate the data. Part of the validation performed is a POST made by the handler to a validation service provided by the payment gateway. This effectively posts some of the original form values received back to the payment gateway to ensure they are valid. The url that I am posting back to is: "https://sandbox.payfast.co.za/eng/query/validate" and the code I am using: /// <summary> /// Posts the data back to the payment processor to validate the data received /// </summary> public static bool ValidateITNRequestData(NameValueCollection formVariables) { bool isValid = true; try { using (WebClient client = new WebClient()) { string validateUrl = (UseSandBox) ? SandboxValidateUrl : LiveValidateUrl; byte[] responseArray = client.UploadValues(validateUrl, "POST", formVariables); // get the resposne and replace the line breaks with spaces string result = Encoding.ASCII.GetString(responseArray); result = result.Replace("\r\n", " ").Replace("\r", "").Replace("\n", " "); if (result == null || !result.StartsWith("VALID")) { isValid = false; LogManager.InsertLog(LogTypeEnum.OrderError, "PayFast ITN validation failed", "The validation response was not valid."); } } } catch (Exception ex) { LogManager.InsertLog(LogTypeEnum.Unknown, "Unable to validate ITN data. Unknown exception", ex); isValid = false; } return isValid; } However, on calling WebClient.UploadValues the following exception is raised: System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure. at System.Net.Security.SslState.StartSendAuthResetSignal(ProtocolToken message, AsyncProtocolRequest asyncRequest, Exception exception) at For the sake of brevity I haven't listed the full call stack (I can do if anyone thinks it will help). The remote certificate does appear to be valid. To get around the problem I did try adding a new RemoteCertificateValidationCallback that always returned true but just ended up getting the following exception: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.Net.ServicePointManager.set_ServerCertificateValidationCallback(RemoteCertificateValidationCallback value) at NopSolutions.NopCommerce.Payment.Methods.PayFast.PayFastPaymentProcessor.ValidateITNRequestData(NameValueCollection formVariables) The action that failed was: Demand The type of the first permission that failed was: System.Security.Permissions.SecurityPermission The Zone of the assembly that failed was: MyComputer So I am not sure this will work in medium trust? Any help would be much appreciated. Thanks Ben

  • Dissertation about website and database security - in need of some pointers

    - by ClarkeyBoy
    Hi, I am on my dissertation in my final year at university at the moment. One of the areas I need to research is security - for both websites and for databases. I currently have sections on the following: Website Form security - such as data validation. This section is more about preventing errors made by legitimate users as much as possible rather than stopping hackers, for example comparing a field to a regular expression and giving them meaningful feedback on any errors which did occur so as to stop it happening again. Constraints. For example if a value must be true or false then use a checkbox. If it is likely to be one of several values then use a dropdown or a set of radio boxes, and so on. If the value is unpredictable then use regular expressions to limit what characters they are allowed to enter, and to restrict the length of the string, and sometimes to limit the format (such as for dates / times, post codes and so on). Sometimes you can limit permissions to the form. This is on the occasion that you know exactly who (whether it be peoples names or a group of people - such as administrators or employees) is going to need access to the form. Restricting permissions will stop members of the public from being able to access the form. Symbols or strings which could be used maliciously or cause the website to act incorrectly (such as the script tag) should be filtered out or html encoded. Captcha images can be used to prevent automated systems from filling in and submitting the form. There are some hacks for file uploads - such as using double extensions - which can allow hackers to upload malicious files. Databases (this is nowhere near done yet but the sections I have planned are listed below) SQL statements vs stored procedures Throwing an error when one of the variables contains particular characters or groups of characters (I cant remember what characters they are, but I have seen a message thrown back at me before where I have tried to enter html or something into a text area). SQL Injection - and ways around it, with some examples. Does anyone have any hints and tips on where I could go for some decent, reliable information either about these areas or about other areas of security that I could cover? Thanks in advance. Regards, Richard PS I am a complete newbie when it comes to security, so please be patient with me. If any of the information I have put down is wrong or could be sub-sectioned then please feel free to say so.

  • requestRouteToHost android

    - by Sam
    Greetings everyone! I'm getting rather fed up with android's ConnectivityManager class. I've been trying for 5 hours to get the requestRouteToHost to work. I'm running my code on the emulator but the requestRouteToHost always fails. I know I have connectivity because I called getActiveNetworkInfo() and it was connected. I've added the ACCESS_NETWORK_STATE and CHANGE_NETWORK_STATE permissions to no avail. Any tips would be greatly appreciated. Sam

  • Facebook Graph API: user gender

    - by Mark
    The old Facebook API provided the user sex/gender as part of the default user data. Apparently the new Graph API does not provide that information, even though the documentation says that it does. I've heard people say that you need to request special permissions to get it and other pieces of data, but I have not been successful in getting it to work. Does anyone have an example, using the Facebook Graph API, of how to get the user's gender and/or location (city/state/country/whatever)?

  • Problems with office automation in asp.net. I can use alternatives such as open-office, if I knew ho

    - by Vinicius Melquiades
    I have a ASP.NET 2.0 web application that should upload a ppt file and then extract its slides to images. For that I have imported office.dll and Microsoft.Office.Interop.PowerPoint.dll assemblies and wrote the following code public static int ExtractImages(string ppt, string targetPath, int width, int height) { var pptApplication = new ApplicationClass(); var pptPresentation = pptApplication.Presentations.Open(ppt, MsoTriState.msoTrue, MsoTriState.msoFalse, MsoTriState.msoFalse); var slides = new List<string>(); for (var i = 1; i <= pptPresentation.Slides.Count; i++) { var target = string.Format(targetPath, i); pptPresentation.Slides[i].Export(target, "jpg", width, height); slides.Add(new FileInfo(target).Name); } pptPresentation.Close(); return slides.Count; } If I run this code in my local machine, in asp.net or a executable, it runs perfectly. But If I try running it in the production server, I get the following error: System.Runtime.InteropServices.COMException (0x80004005): PowerPoint could not open the file. at Microsoft.Office.Interop.PowerPoint.Presentations.Open(String FileName, MsoTriState ReadOnly, MsoTriState Untitled, MsoTriState WithWindow) at PPTImageExtractor.PptConversor.ExtractImages(String caminhoPpt, String caminhoDestino, Int32 largura, Int32 altura, String caminhoThumbs, Int32 larguraThumb, Int32 alturaThumb, Boolean geraXml) at Upload.ProcessRequest(HttpContext context) The process is running with the user NT AUTHORITY\NETWORK SERVICE. IIS is configured to use anonymous authentication. The anonymous user is an administrator, I set it like this to allow the application to run without having to worry about permissions. In my development machine I have office 2010 beta1. I have tested with the executable in a pc with office 2007 as well. And if I run the code from the executable in the server, with office 2003 installed, it runs perfectly. To ensure that there wouldn't be any problems with permissions, everyone in the server has full access to the web site. The website is running in IIS7 and Classic Mode. I also heard that Open-office has an API that should be able to do this, but I couldn't find anything about it. I don't mind using DLLImport to do what I have to do and I can install open-office on the web server. Don't worry about rewriting this method, as long as the parameters are the same, everything will work. I appreciate your help. ps: Sorry for bad English.

  • Chrome Extension - Cross-Origin XMLHttpRequest - Returning HTML/JSON

    - by Tyler
    Hi everyone, I hope you can help me :) I've created a Chrome extension (my first one) and I'm having some difficulty auto-populating a <select> with <option> that are being returned. the default_popup page is index.htm. I have two <select> (listboxes? can't remember the name) boxes. When a user first clicks the extension, it performs a XMLHttpRequest to a php script and get's a list of names from a MySQL database. It returns (onLoad) the list in the form of: <option>blah</option> When a user selects an option from the first listbox/select, it performs another XMLHttpRequest and auto-populates the second listbox/select. Then when a user selects an option from the second listbox it will eventually populate a few details further down the page. I've been testing by just running the index.htm file and seeing if just the code works correctly, which it does. However when trying to view it from the extension, it doesn't work. The onLoad doesn't fill in the first listbox, and selecting an option (one that I typed in the box for testing purposes) from the first listbox doesn't populate the second listbox. I thought maybe it was a permissions error, so I tried adding the domain to the manifest.json file; but I appear to be getting an error in the manifest.json file after doing so. In my default_popup (index.htm) file I have this script for my XMLHttpRequest: <script type="text/javascript"> function getClient(str,type) { if (str=="") { document.getElementById(type).innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById(type).innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","http://(domain removed)/Extension/getInfo.php?q="+type+"&c="+str,true,"user","pass"); xmlhttp.send(); } </script> This is what my manifest.json file looks like: { "name": "Client Center Lite", "version": "1.0", "description": "blah", "browser_action": { "default_icon": "images/icon_19.png", "default_popup": "index.htm", "default_title": "Client Center Lite" }, "icons":{ "128":"images/icon_128.png" } "permissions": { "http://(domain removed)/" }, } Am I doing this correctly? The point of the extension is to be able to quickly view client details. The extension will only be given to employees locally in a .crx file, and not distributed online. The domain I am accessing through the PHP/MySQL is accessible from the web, but I'm currently using localhost in my mysql_connect string. Do I need to be returning the <option> elements encoded as JSON? If so, I'm completely cluesless as how to do that.

  • Facebook Developer ToolKit: How should I construct this app?

    - by j0nscalet
    I have created a simple desktop application that I want to use to post status updates for the users of my app. Here's the kicker though that I am having trouble figuring out, the desktop application runs as part of a batch process every night, in which I update the status of certain users. I use the following code to accomplish this: (comes directly from the FDK samples) public FriendViewer() { InitializeComponent(); facebookService1.ApplicationKey = "Key"; facebookService1.Secret = "Secret"; facebookService1.SessionKey = "Session key"; facebookService1.IsDesktopApplication = true; } private void TestService_Load(object sender, EventArgs e) { try { if (!facebookService1.API.users.hasAppPermission(facebook.Types.Enums.Extended_Permissions.status_update)) facebookService1.GetExtendedPermission(facebook.Types.Enums.Extended_Permissions.status_update); if (!facebookService1.API.users.hasAppPermission(facebook.Types.Enums.Extended_Permissions.offline_access)) facebookService1.GetExtendedPermission(facebook.Types.Enums.Extended_Permissions.offline_access); long uid = facebookService1.users.getLoggedInUser(); facebook.Schema.user user = facebookService1.users.getInfo(uid); facebookService1.users.setStatus("Facebook Syndicator rules!"); MessageBox.Show(String.Format("Status set for {0} {1}", user.first_name, user.last_name)); } catch (Exception ex) { MessageBox.Show(ex.Message); Close(); } } My user's day to day activity is done a website front end. Since I dont have any user interaction in a nightly batch process, I cannot use the ConnectToFaceBook method on the FaceBookService to obtain a sessionKey for the user. Ideally I would like to prompt for authorization and extended permissions for my desktop app when a user logins into the web front end then save the sessionKey and uid in the database. At night when my process runs, I would reference the sessionKey and uid in order and update the user's status. I am finding myself fumbling between whether or not my app should be a web or desktop app. Having both a web and desktop app would be confusing to my users, because they would have to grant/manage permissions for both apps. And I looking at this the wrong way? Any help would be greatly appreciated! Thanks.

  • How to send a Facebook notification through their API

    - by at
    I asked this on the Facebook Developers Forum with no responses.. How do I send notifications to users so they show up in the Notifications globe icon tab on the top left of a user's Facebook page? Some applications I use have their notifications show up there, but I don't see how that mechanism works in Facebook's API docs. Neither are there any permissions which seem to be required to send users notifications.

  • Run word on server for COM to work??

    - by chupinette
    I got this from php.net website. This is related to the problem I am having with tho code below. Can anyone explain me what the following does. I am using Vista. What does running Word on server implies? In order to get the Word example running, do the following on the server side. Worked for me... 1. Click START--RUN and enter "dcomcnfg" 2. In the "Applications" tab, go down to "Microsoft Word Document" 3. Click PROPERTIES button 4. Go to the "Security" Tab 5. Click "Use custom access permissions", and then click EDIT 6. Click ADD and then click SHOW USERS 7. Highlight the IIS anonymous user account (usually IUSR_), click ADD 8. Go back to the "Security" tab by hitting OK 9. Click "Use custom launch permissions", and the click EDIT 10. Click ADD and then click SHOW USERS 11. Highlight the IIS anonymous user account (usually IUSR_), click ADD 12. Hit OK, and then hit APPLY. Also, you should look at the "Identity" tab in the Microsoft Word Document PROPERTIES and see that it is set to "Interactive User" ALSO, log into the machine AS the IUSR_ account, start word, and make sure to click through the dialog boxes that Word shows the first time it is run for a certain user. In other words, make sure Word opens cleanly for the IUSR_ user. <?php // starting word $word = new COM("word.application") or die("Unable to instantiate Word"); echo "Loaded Word, version {$word->Version}\n"; //bring it to front $word->Visible = 1; //open an empty document $word->Documents->Add(); //do some weird stuff $word->Selection->TypeText("This is a test..."); $word->Documents[1]->SaveAs("Useless test.doc"); //closing word $word->Quit(); //free the object $word = null; ?>
