  • How to configure database connection securely

    - by chiccodoro
    Similar but not the same: How to securely store database connection details Securely connecting to database within a application Hi all, I have a C# WinForms application connecting to a database server. The database connection string, including a generic user/pass, is placed in a NHibernate configuration file, which lies in the same directory as the exe file. Now I have this issue: The user that runs the application should not get to know the username/password of the general database user because I don't want him to rummage around in the database directly. Alternatively I could hardcode the connection string, which is bad because the administrator must be able to change it if the database is moved or if he wants to switch between dev/test/prod environments. So long I've found three possibilities: The first referenced question was generally answered by making the file only readable for the user that runs the application. But that's not not enough in my case (the user running the application is a person. The database user/pass are general and shouldn't even be accessible by the person.) The first answer additionally proposed to encrypt the connection data before writing it to the file. With this approach, the administrator is not able anymore to configure the connection string because he cannot encrypt it by hand. The second referenced question provides an approach for this very scenario but it seems very complicated. My questions to you: This is a very general issue, so isn't there any general "how-to-do-it" way, somehow a "design pattern"? Is there some support in .NET's config infrastructure? (optional, maybe out of scope) Can I combine that easily with the NHibernate configuration mechanism?

  • App with MVC Virtual application shared AuthCookie.

    - by Razcer
    I have a 3.5 ASP.Net WebForm parent application. The parent uses forms authentication. I have a MVC child virtual application, I would like to make it so the user logs in to the parent application, user then navigates to the virtual application by pressing a link on the parent. However every time I do this it goes to the login screen for the virtual application. Is there a web setting I should double check in Parent? Or Child? Is there an IIS setting that I should check? Should I be using a virtual directory instead of virtual application? I want the child to be able to access the Session[] from the parent. I would like the child app to use the same authCookie as the parent app.

  • GAE/J: unable to register a custom ELResolver

    - by dfa
    I need to register a custom ELResolver for a Google App Engine project. Since it must be registered before any request is received, as specified by the Javadoc: It is illegal to register an ELResolver after the application has received any request from the client. If an attempt is made to register an ELResolver after that time, an IllegalStateException is thrown. I'm using a ServletContextListener: public class RegisterCustomELResolver implements ServletContextListener { @Override public void contextInitialized(ServletContextEvent sce) { ServletContext context = sce.getServletContext(); JspApplicationContext jspContext = JspFactory.getDefaultFactory().getJspApplicationContext(context); jspContext.addELResolver(new MyELResolver()); } ... } The problem is that JspFactory.getDefaultFactory() returns always null. I've alreay filled a bug report. Any idea for a workaround?

  • How to host a scalable social networking app

    - by christopher-mccann
    I am in the middle of developing a social networking application for a very select user niche which could scale to a few million users. Right now I have always hosted applications on RackSpace Cloud and I have no issues with them at all - always been a really good service and never had any downtime. My question is though does anyone think that cloud computing is not the way to host scalable web apps? Or can anyone with experience of this recommend a better solution. I have always shunned trying to run big servers from my own facilities as I think it seems silly to go to the expense of bringing in big alternative power supplies and all the other necessary precautions when other companies already do this. I looked at managed hosting services but this proved to be a bit too expensive for us at the start and the scalability of it wasnt good enough - it would take a day or two to get a new server provisioned. Therefore I ended up on a cloud platform. If anyone has any recommendations or advice it would be greatly appreciated.

  • sproutcore or cappucino for web app development?

    - by swami
    I recently found out about the sproutcore and capuccino frameworks for web app development as proper MVC approach to creating Desktop-like applications. As far as I could understand, the main difference between the two frameworks is that Cappucino abstracts away the HTML+CSS+Javascript to Objective-J - a new programming language developed be the creators of Capuccino that adds OO capabilities to Javascript, whereas Sproutcore uses HTML5,CSS,Javascript. After lots of pondering, I thought it's probably best to go with technologies we know, so I downloaded the Sproutcore tools and did the tutorials, and I have to say I was very impressed. Just the kind of thing I was looking for, for organizing a complex web app. However, I just stumbled across the following link: http://charlesjolley.sys-con.com/node/1341228 in which Charles Jolley (the creator of Sproutcore) syas that he's tired of waiting for the HTML5 and ECMAScript5 specs to get finalized, and announces that from version 1.1 onwards they will be switching to Objective-J ! So now the question is - what will actually differentiate Sproutcore and Capuccino - and which one should I choose now? Kind Regards Swami

  • Can I add an additional eula/tos inside my app on top of the iphone app store agreement

    - by nickthedude
    I have an app that allows users to generate and publish content. I would like to possibly be able to use the content they publish/create to make derivative works, ie books etc (similar to what icanhazcheeseburger has done.) If I were to put an opt in alert to ask the user whether or not they would like to be a part of this, would this violate the iphone sdk? I know this is not programming question so I'm not sure if this is a fair question, but I thought I heard something like you can't add a eula you have to abide by whatever apple dictates in their app store agreement. Also if you have suggestions on different ways to approach getting users to agree to this I'm all ears, but yes that is kind of subjective. Thanks folks, Nick

  • The height and width properties on my Flex 4 app arn't working

    - by ben
    In the opening application tag of my Flex 4 app, I set the width and height properties as follows: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" creationComplete="init()" backgroundColor.mainState="0x303030" xmlns:components="components.*" width="798" height="240"> What I go into Design mode in Flash Builder 4, the app is the correct size. But when I embed the .swf file into a HTML page, the application's background color covers the whole screen, and when the Flash Player Settings message box pops up it is outside of the area I defined in the code above. What am I doing wrong? Thanks for reading.

  • Can't find .Net 2.0 XML Schema

    - by Zach Smith
    I'm currently setting up an application config for a WPF application written in .Net 4.0. The connection string in the app.config is encrypted like so: <connectionStrings configProtectionProvider="DataProtectionConfigurationProvider"> <EncryptedData> <CipherData> <CipherValue>CypherValue</CipherValue> </CipherData> </EncryptedData> </connectionStrings> To use the EncryptedData element I need to include the XMLNS "http://schemas.microsoft.com/.NetConfiguration/v2.0". Attempting to include it produces an error as the schema cannot be found. Is there a way to include the schema or perhaps a different element I could use instead of EncryptedData?

  • Kerberos: Running an app with a parameter using krenew

    - by Mihai Todor
    I need to run an application with krenew, but the application also needs to receive a parameter via command line and I need to send its output to a file. From the documentation, it looks like this should do the trick: krenew -t -- sh -c 'compute-job > /afs/local/data/output' but, unfortunately, when I run the command below: krenew -s -- sh -c './my_app config.xml > results/test.txt &' the application just dies after a while and I can see from the output of ps aux that krenew is not running along with my_app. I am not sure what the parameter -t does, and as far as I can see, if I run krenew -s ./my_app, it works properly. I hope someone can clarify this.

  • How to think in data stores instead of databases?

    - by Jim
    As an example, Google App Engine uses data stores, not a database, to store data. Does anybody have any tips for using data stores instead of databases? It seems I've trained my mind to think 100% in object relationships that map directly to table structures, and now it's hard to see anything differently. I can understand some of the benefits of data stores (e.g. performance and the ability to distribute data), but some good database functionality is sacrificed (e.g. joins). Does anybody who has worked with data stores like BigTable have any good advice to working with them?

  • Debug IPhone App on 3.1.2 Phone

    - by Steblo
    Hello, I recently finished my first IPhone app and want to test it on my device now. I registered (and paid) for an Developer Account and managed to install the required certificates. Unfortunately my device is on firmware 3.1.2 (which I don't want to upgrade). My SDK only shows 3.1.3 as possible Target. As a result it can't be installed on my 3.1.2 device. Where can I set/change to target platform ? Otherwise my App would only run on the newest firmwares, right ? Instead I want to provide it to every User with OS 3.0

  • Spring - Redirect after POST (even with validation errors)

    - by Taylor L
    I'm trying to figure out how to "preserve" the BindingResult so it can be used in a subsequent GET via the Spring <form:errors> tag. The reason I want to do this is because of Google App Engine's SSL limitations. I have a form which is displayed via HTTP and the post is to an HTTPS URL. If I only forward rather than redirect then the user would see the https://whatever.appspot.com/my/form URL. I'm trying to avoid this. Any ideas how to approach this? Below is what I'd like to do, but I only see validation errors when I use return "create". @RequestMapping(value = "/submit", method = RequestMethod.POST) public final String submit( @ModelAttribute("register") @Valid final Register register, final BindingResult binding) { if (binding.hasErrors()) { return "redirect:/register/create"; } return "redirect:/register/success"; }

  • Is it possible to change "working directory" of XeTeX?

    - by Herbert Sitz
    Using XeTeX there are many working files that get created in process of producing the pdf, and they litter the directory where my main .tex file is. Is it possible to change the working directory of XeTeX so that it stores all these scratch files in some other directory, out of the way? There is a previous question on Superuser.com that discusses a utility that cleans up the working files by deleting them after they're produced: http://superuser.com/questions/95712/how-to-avoid-littering-ones-tex-directories-with-intermediate-files That solution doesn't work for me since I'm using XeTeX, but also it seems like it would be preferable to simply be able to designate a "scratch" directory where all working files are saved. I haven't been able to find any info on how to do it though. Is there a way? (My question is prompted partly because of the fact that I often work with files in a directory that is shared using DropBox, so it creates a lot of unnecessary traffic if files are getting created and destroyed willy nilly. I don't know if it affects speed in any way, but the idea of having a separate working directory that is not shared/replicated by DropBox would be a cleaner solution, even if I could use the method suggested in the earlier thread.)

  • Sending the variable's content to my mailbox in Python?

    - by brilliant
    I have asked this question here about a Python command that fetches a URL of a web page and stores it in a variable. The first thing that I wanted to know then was whether or not the variable in this code contains the HTML code of a web-page: from google.appengine.api import urlfetch url = "http://www.google.com/" result = urlfetch.fetch(url) if result.status_code == 200: doSomethingWithResult(result.content) The answer that I received was "yes", i.e. the variable "result" in the code did contain the HTML code of a web page, and the programmer who was answering said that I needed to "check the Content-Type header and verify that it's either text/html or application/xhtml+xml". I've looked through several Python tutorials, but couldn't find anything about headers. So my question is where is this Content-Type header located and how can I check it? Could I send the content of that variable directly to my mailbox? Here is where I got this code. It's on Google App Engines.

  • Cocoa app not launching on build & go but launching manually

    I have quite the interesting problem.

  • Get All Users in an Active Directory Group

    I'm using the following code sample to get a list of all users in a specified AD group (in this case, all users in the "Domain Users" group). My listed code works great, with one exception: it won't return users who have their primary group set to "Domain Users". How can I get a list of all users in the group, including those who have it set as their primary group?

  • java.lang.NoClassDefFoundError: com/google/appengine/tools/enhancer/Enhance

    - by user1204337
    I am new to GAE, I follow the instructions on http://code.google.com/eclipse/docs/install-eclipse-3.7.html. I got the installation and registration done pretty fast. But when I tried to build the helloWorld project in Eclipse, before I can do anything, Eclipse gives me an error says "java.lang.NoClassDefFoundError: com/google/appengine/tools/enhancer/Enhance" and it is very weird. Because when you expand the app engine sdk, you can easily find the Enhance class under related jar file. I also tried Enhance e = null; and it is working. It seems that my eclipse just cannot find it. I don't know why it is not working, I am using JDK1.6, I reinstall my eclipse and the google plugins, I even disabled my firewall. Please help!!!

  • Limiting ssh user account only to access his home directory!

    - by EBAGHAKI
    By reading some tutorials online I used these commands: Make a local group: net localgroup CopsshUsers /ADD Deny access to this group at top level: cacls c:\ /c /e /t /d CopsshUsers Open access to the copSSH installation directory: cacls copssh-inst-dir /c /e /t /r CopsshUsers Add Copssh user to the group above: net localgroup CopsshUsers mysshuser /add simply put these commands will try to create a usergroup that has no permission on your computer and it only have access to the copSSH Installation directory. This is not true, since you cannot change the permission on your windows directory, the third command won't remove access to windows folder (it says access denied on his log). Somehow I achieved that by taking ownership of Windows folder and then i execute the third command so CopsshUsers has no permissions on windows folder from now on. Now i tried to SSH to the server and it simply can't login! this is kind of funny because with permission on windows directory you can login and without it you can't!! So if you CAN SSH to the server somehow you know that you have access to the windows directory! (Is this really true??) Simple task: Limiting ssh user account only to access his home directory on WINDOWS and nothing else! Guys please help!

  • Enabling mod_wsgi in Apache for a Django app on Gentoo

    - by hobbes3
    I installed Apache, Django, and mod_wsgi on Gentoo using emerge (on Amazon EC2). I know that the mod_wsgi is configured in /etc/apache2/modules.d/70_mod_wsgi.conf: <IfDefine WSGI> LoadModule wsgi_module modules/mod_wsgi.so </IfDefine> # vim: ts=4 filetype=apache So in my /etc/conf.d/apache I added the WSGI module: APACHE2_OPTS="-D DEFAULT_VHOST -D INFO -D SSL -D SSL_DEFAULT_VHOST -D LANGUAGE -D WSGI" But when I try to list the loaded module, mod_wsgi isn't listed. root ~ # apache2 -M | grep wsgi Syntax OK I also know that mod_wsgi isn't loading properly because the Apache configuration file doesn't recognize WSGIScriptAlias. By the way for Django to work I need to include a custom Apache configuration file. Where should I insert the line below? Include "/var/www/localhost/htdocs/mysite/apache/apache_django_wsgi.conf" I currently have that in the httpd.conf file but I feel like that file will get reseted whenever I upgrade Gentoo or related package. EDIT: it seems the mod_wsgi file is located in /usr/lib64/apache2/modules/mod_wsgi.so. Here is my detailed Apache settings: root@ip-99-99-99-99 /usr/portage/eclass # apache2 -V Server version: Apache/2.2.21 (Unix) Server built: Mar 7 2012 06:52:30 Server's Module Magic Number: 20051115:30 Server loaded: APR 1.4.5, APR-Util 1.3.12 Compiled using: APR 1.4.5, APR-Util 1.3.12 Architecture: 64-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/usr" -D SUEXEC_BIN="/usr/sbin/suexec" -D DEFAULT_PIDLOG="/var/run/httpd.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="/var/run/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="/etc/apache2/mime.types" -D SERVER_CONFIG_FILE="/etc/apache2/httpd.conf"

  • How to handle security constraints using GWT 2.1's RequestFactory?

    - by Marc
    I am currently developing a GWT 2.1 application that is to be deployed on Google App Engine. I would like to realise the server communication using the new RequestFactory. Now my question is how to handle fine-grained security issues in this context? Some server actions (of those declared in the RequestContext stubs) shall be restricted to certain users (possibly depending on the parameters of the remote call). If a call is unauthorised, I would like the client to show a login page (so that one may log in as a different user, for example). From the Expenses example, I know how to implement an automatic redirection to a login page, but in this example, the security model is quite simple: A client is allowed to access the servlet if and only if a user is logged in. Shall I raise a custom UnAuthorizedException in my server-side service? Where should I intercept this exception? (Can I do this in a servlet filter like the GaeAuthFilter of the Expenses example?)
