• Credit Card storage solution

  - by jtnire

  Hi Everyone, I'm developing a solution that is designed to store membership details, as well as credit card details. I'm trying to comply with PCI DSS as much as I can. Here is my design so far: PAN = Primary account number == long number on credit card Server A is a remote server. It stores all membership details (Names, Address etc..) and provides indivudal Key A's for each PAN stored Server B is a local server, and actually holds the encrypted PANs, as well as Key B, and does the decryption. To get a PAN, the client has to authenticate with BOTH servers, ask Server A for the respective Key A, then give Key A to server B, which will return the PAN to the client (provided authentication was sucessful). Server A will only ever encrypt Key A with Server B's public Key, as it will have it beforehand. Server B will probably have to send a salt first though, however I doin't think that has to be encrypted I havn't really thought about any implementation (i.e. coding) specifics yet regarding the above, however the solution is using Java's Cajo framework (wrapper for RMI) so that is how the servers will communicate with each other (Currently, membership details are transfered in this way). The reason why I want Server B to do the decryption, and not the client, is that I am afraid of decryption keys going into the client's RAM, even though it's probably just as bad on the server... Can anyone see anything wrong with the above design? It doesn't matter if the above has to be changed. Thanks jtnire

• joomla and allow_url_fopen [closed]

  - by liz

  so i have been reading of the pros and cons of allowing: allow_url_fopen. but i am still confused. after a recent hacking incident (which i believe had nothing to do with allow_url_fopen) my host turned allow_url_fopen off. so the thing i dont get is, in joomla 2.5.x there is an updating feature.you can search for new versions and be notified if things are out of date. there is a big security hole if joomla or its extensions get out of date. But the catch it needs allow_url_fopen turned on. so why did joomla build a security risk into a feature to improve security??is it okay to turn allow_url_fopen on and have the updating feature? to clarify: my question is. i have Joomla installed. I have CURl installed. when i run the discover updates through NATIVE joomla i get a request for fopen. shouldn't i not need to enable a security risk? i am running version 2.5.8 of joomla.

• Cannot connect to SQL Server from ASP.NET MVC app

  - by Dan Fergus

  I have an ASP.NET MVC app that has on a hosted server for over a year, connecting to SQL Server. I've had to change hosting services, the new one supports MVC 1.0. I've also moved a non MVC ASP app to the same hosting service. Now, MY MVC based app retturnes this error when I try to validate a user login. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) Now, the non-MVC app can access the exact same database and authenticate users just fine. The MVC app, when run from my dev box connects fine. It also run/connects/authenticates without problem when I install and run the site from an internal SQL 2008 server running IIS 7. I, along with the hosting support techs, am at a loss how the exact same connect string works every where except on the hosted server, and only when run from inside an ASP.NET MVC web app. Any ideas would be greatly appreciated.

• VirtualBox limits size of .js file, that can be included from guest additions folder?

  - by c69

  This question might belong to SuperUser, but i'll try to ask it here anyway, because i believe, some web developers might encountered this weird behavior. When testing a site for IE8/winXP compatibility on VirtualBox i run into weird issue of $ is undefined, which is caused by jQuery (and jQuery UI) being not included, when referenced by relative path, which resolves to file:/// url. Seemingly because their size was too big (above 200KB). Simply replacing links to those 2 big files to http:// ones solved the issue for me. But here is the question: why did this happen ? is it a misconfiguration ? a bug ? a known design decision ? Details: VirtualBox 4.1.8 host os: win7 64bit, guest os: xp sp3 32 bit guest additions installed, page was launched from VB shared folder the bug was manifesting itself in all browsers (even in opera, which ignores ie security settings, afaik) ie configuration is default script was included like this: <script type="text/javascript" src="js/libs/jquery/jquery-1.7.2.js"> exact size limit was not deducted.

• Using Kerberos authentication for SQL Server 2008

  - by vivek m

  I am trying to configure my SQL Server to use Kerberos authentication. My setup is like this - My setup is like this- I have 2 virtual PCs in a Windows XP Pro SP3 host. Both VPCs are Windows Server 2003 R2. One VPC acts as the DC, DNS Server, DHCP server, has Active Directory installed and the SQL Server default instance is also running on this VPC. The second VPC is the domain member and it acts as the SQL Server client machine. I configured the SPN on the SQL Server service account to get the Kerberos working. On the client VPC it seems like it is using Kerberos authentication (as desired)- C:\Documents and Settings\administrator.SHAREPOINTSVC>sqlcmd -S vm-winsrvr2003 1> select auth_scheme from sys.dm_exec_connections where session_id=@@spid 2> go auth_scheme ---------------------------------------- KERBEROS (1 rows affected) 1> but on the server computer (where the SQL Server instance is actually running) it looks like it is still using NTLM authentication- . This is not a remote instance, the sql server is local to this machine. C:\Documents and Settings\Administrator>sqlcmd 1> select auth_scheme from sys.dm_exec_connections where session_id=@@spid 2> go auth_scheme ---------------------------------------- NTLM (1 rows affected) 1> What can i do so that it uses Kerberos on the server computer as well ? (or is this something that I should not expect)

• Bookmarklet, js injection and popup issue

  - by Neewok

  I'm currently writing a bookmarklet that loads and executes a remote js file by appending a new <script> tag in the current window, like so : javascript:(function() { if(typeof __bml_main != "undefined") return __bml_main.init(); var s= document.createElement('script'); s.type= 'text/javascript'; s.src= 'http://127.0.0.1:8000/media/bookmarklet.js'; void(document.body.appendChild(s)); })(); My bookmarklet needs to perform some dom manipulations in order to extract data from the page being viewed, and then to open a new popup to list them. The thing is : if I want to bypass pop-up blockers, I can't open my new window from the injected script. I need to open it right from the beginning in the bookmarklet code, and to access it later when needed. I've tried to do somehting like this : javascript:var my_popup = window.open('http://127.0.0.1:8000/resources/manage/new/', 'newResourcePopup',config='height=200,width=400,toolbar=no,menubar=no,scrollbars=no,resizable=no,location=no,directories=no,status=no'); (function() { // script injection (...) })(); but if I then try to access my_popup from my remotely loaded script, most browsers will throw a security warning and won't let me access the Window object. This is understandable since the script is not from the same domain than the displayed page, but I'm kind of stuck... A solution would be to use a div overlay, but I'd really prefer to open a window in this case. Any hints ?

• Python on Mac: Fink? MacPorts? Builtin? Homebrew? Binary installer?

  - by BastiBechtold

  For the last few days, I have been trying to use Python for some audio development. The thing is, Mac OSX does not handle uninstalling stuff well. Actually, there is no way to uninstall anything. Once it is on your system, you better pray that it didn't do any funny stuff. Hence, I don't really want to rely on installer packages for Python. So I turn to Homebrew and install Python using Homebrew. Works fabulously. Using pip, Numpy, SciPy, Matplotlib were no (big) problem, either. Now I want to play audio. There is a host of different packages out there, but pip does not seem willing to install any. But, there is a binary distribution for PyGame, which I guess should work with the built-in Python. Hence my question: What would you do? Would you just install the binary distributions and hope that they interoperate well and never need uninstalling? Would you hack your way through whichever package control management system you prefer and deal with its problems? Something else?

• FileReference.browse() stops playback on some Flash Players

  - by Christophe Herreman

  We have an issue were the server session associated with a Flex client times out when the browse file dialog is open for a time longer then the configured session timeout. It seems that on some players, the playback is stopped when browse or download on a FileReference is executing. This also causes remote calls to be blocked and hence our manual keep-alive messages are not sent to the server, resulting in a session timeout. I searched for some info on this in the docs and found a notice of it, but it does not explicitly list the players it does (not) work. Would anyone know were I could find a complete list? PS: here are the links that mention this behavior: http://livedocs.adobe.com/flex/3/html/help.html?content=17_Networking_and_communications_7.html While calls to the FileReference.browse(), FileReferenceList.browse(), or FileReference.download() method are executing, most players will continue SWF file playback. http://livedocs.adobe.com/flex/3/langref/flash/net/FileReference.html While calls to the FileReference.browse(), FileReferenceList.browse(), or FileReference.download() methods are executing, SWF file playback pauses in stand-alone and external versions of Flash Player and in AIR for Linux and Mac OS X 10.1 and earlier Anyone knows what is meant with an "external Flash Player"? PPS: we tested this on Linux (10.0.x and 10.1.x) in Firefox where it seems to stop playback and on Windows (10.0.x) in IE where playback seems to continue.

• Resque: Slow worker startup and Forking

  - by David John

  I'm currently moving my application from a Linode setup to EC2. Redis is currently installed on a remote instance with various worker instances interacting with the queue. Thats all going fantastic. My problem is with the amount of time it takes for a worker to be 'instantiated' and slow forking. Starting a worker will usually take between 30 seconds and a minute(from god.rb starting the worker rake task and the worker actively starting work on the queue). I could live with that, but I've not experienced such a wait time on my current Linode production box so I believe its one of my symptoms to a bigger problem. Next issue is that jobs that took a second or less in my previous environment now seem to take about 5 to 10 times longer.. I'm assuming this must be some sort of issue with my Ubuntu install on EC2? One notable difference is that I'm running REE 1.8.7-2010.01 in my new setup, and REE 1.8.6 on the old Linode boxes. Anyone else experienced these issues?

• Limit TCP requests per IP

  - by asmo

  Hello! I'm wondering how to limit the TCP requests per client (per specific IP) in Java. For example, I would like to allow a maximum of X requests per Y seconds for each client IP. I thought of using static Timer/TimerTask in combination with a HashSet of temporary restricted IPs. private static final Set<InetAddress> restrictedIPs = Collections.synchronizedSet(new HashSet<InetAddress>()); private static final Timer restrictTimer = new Timer(); So when a user connects to the server, I add his IP to the restricted list, and start a task to unrestrict him in X seconds. restrictedIPs.add(socket.getInetAddress()); restrictTimer.schedule(new TimerTask() { public void run() { restrictedIPs.remove(socket.getInetAddress()); } }, MIN_REQUEST_INTERVAL); My problem is that at the time the task will run, the socket object may be closed, and the remote IP address won't be accessible anymore... Any ideas welcomed! Also, if someone knows a Java-framework-built-in way to achieve this, I'd really like to hear it.

• using libcurl to check if a file exists on a SFTP site

  - by Snazzer

  I'm using C++ with libcurl to do SFTP/FTPS transfers. Before uploading a file, I need to check if the file exists without actually downloading it. If the file doesn't exist, I run into the following problems: //set up curlhandle for the public/private keys and whatever else first. curl_easy_setopt(CurlHandle, CURLOPT_URL, "sftp://user@pass:host/nonexistent-file"); curl_easy_setopt(CurlHandle, CURLOPT_NOBODY, 1); curl_easy_setopt(CurlHandle, CURLOPT_FILETIME, 1); int result = curl_easy_perform(CurlHandle); //result is CURLE_OK, not CURLE_REMOTE_FILE_NOT_FOUND //using curl_easy_getinfo to get the file time will return -1 for filetime, regardless //if the file is there or not. If I don't use CURLOPT_NOBODY, it works, I get CURLE_REMOTE_FILE_NOT_FOUND. However, if the file does exist, it gets downloaded, which wastes time for me, since I just want to know if it's there or not. Any other techniques/options I'm missing? Note that it should work for ftps as well. Edit: This error occurs with sftp. With FTPS/FTP I get CURLE_FTP_COULDNT_RETR_FILE, which I can work with.

• Ideas Needed for a Base Code System

  - by Tegan Snyder

  I've developed a PHP web application that is currently in need of a strategic restructuring. Currently when we setup new clients we give them the entire code base on a subdomain of our main domain and create a new table for them in the database. This results in each client having the entire codebase, meaning when we make bug changes, fixes we have to go back and apply them independently across all clients and this is a pain. What I'd like to create is a base code server that holds all the core PHP files. base.domain.com Then all of our clients (client.domain.com) will only need a few files: config.php would have the database connection information. index.php - displays the login box if session non-existant, otherwise it loads baseline code via remote includes to base.domain.com. My question is does my logic seem feasible? How do other people handle similar situations by having a base code? Also.... Is it even possbile to remotely include PHP files from base.domain.com and include them in client.domain.com? Thanks, Tegan

• Visual Studio 2010 randomly unable to debug WCF service.

  - by rossisdead

  I'm running Visual Studio 2010 on a Windows 7 x64 machine, and occasionally VS is giving me the good old "The remote procedure could not be debugged.This usually indicates that debugging has not been enabled on the server" error that a lot of people ask about. My problem, though, is that it seems to only do this randomly(it can be anywhere from a few minutes to a few hours), and after I've made plenty of successful calls to the service already. It doesn't prevent the service from working. It still returns values and doesn't throw any errors. The only difference is that annoying dialog pops up everytime I start to debug my application. I should mention that I'm connecting the WCF service from a WPF application. If I launch the web site the service is part of, I don't get the dialog. A few of the things I've tried that do not work: Killing and restarting the server. Compiling the web server in x86 Enabling tracing, but couldn't find any problems. Is this just a bug in Visual Studio 2010, or is there something I'm missing?

• How to build a simulation of a login hardware token in .Net

  - by Michel

  Hi, i have a hardware token for remote login to some citrix environment. When i click the button on the device, i get an id and i can use that to login to the citrix farm. I can click the button as much as i like, and every time a new code gets generated, and they all work. Now i want to secure my private website likewise, but not with the hardware token, but with a 'token app' on my phone. So i run an app on my phone, generate a key, and use that to (partly) authenticate myself on the server. But here's the point: i don't know how it works! How can i generate 1, 2 or 100 keys at one time which i can see (on the server) are all valid, but without the server and the phone app having contact (the hardware token also is an 'offline' solution). Can you help me with a hint how i would do this? This is what i thought of so far: the phone app and the server app know (hardcoded) the same encryption key. The phone app encrypts the current time. The server app decrypts the string to the current time and if the diff between that time and the actual server time is less than 10 minutes it's an ok. Difficult for other users to fake a key, but encryption gives such nasty strings to enter, and the hardware token gives me nice things like 'H554TU8' And this is probably not how the real hardware token works, because the server and the phone app must 'know' the same encryption key.

• problems with retrieving data that was saved outside of a grails webflow

  - by callie16

  Hi, this is actually connected to an earlier question of mine here. Anyway, I have 3 domains that look like this: class A { ... static hasMany = [ b : B ] ... } class B { ... static belongsTo = [ a : A ] static hasMany = [ c : C ] ... } class C { ... static belongsTo = [ b : B ] ... } In my GSP page, I call an action in the Controller via a remote function in a javascript block (I'm using Dojo so I'm passing data to be saved this way... it's not a form per se so I use JSON for now to pass the data to the Controller). Let's say, I'm calling something like this: def someAction = { def jsonArr = [parse the JSON here] def tmpA = A.get(params.id) ... def tmpB = new B() b.someParam = jsonArr.someParam ... def tmpC = new C() tmpC.cParam = jsonArr.cParam tmpB.addToC(tmpC) tmpB.save(flush: true) //this may or may not be here but I'm adding it for the sake of completeness tmpA.addToB(tmpB) tmpA.save(flush: true) // NOTE: If I check here via println or whatnot, tmpA has a tmpB which has a tmpC... in other words, the data got saved. It's also in the DB. redirect(action: 'order' ...) } Then comes the fun part. Here's the webflow sample: def orderFlow = { ... someStateIShouldEndUpIn { on("next") { // or on previous... doesn't matter def anId = params.id def currA = A.get(anId) // this does NOT return a null value def testB = currA.b // this DOES return a null value }.to("somePage") ... } ... } Any ideas on why this happens? Moreover, when I dump the data of currA, b=null... instead of b=[] or b=[contents of tmpB]. Any help would be seriously appreciated... been at this for a couple of days now... Thanks!

• Chrome targeted CSS

  - by Chris

  I have some CSS code that hides the cursor on a web page (it is a client facing static screen with no interaction). The code I use to do this is below: *, html { cursor: url('/web/resources/graphics/blank.cur'), pointer; } Blank.cur is a totally blank cursor file. This code works perfectly well in all browsers when I host the web files on my local server but when I upload to a Windows CE webserver (our production unit) the cursor represents itself as a black box. Odd. After some testing it seems that chrome only has a problem with totally blank cursor files when served from WinCE web server, so I created a blank cursor with one pixel as white, specifically for chrome. How do I then target this CSS rule to chrome specifically? i.e. *, html { cursor: url('/web/resources/graphics/blank.cur'), pointer; } <!--[if CHROME]> *, html { cursor: url('/web/resources/graphics/blankChrome.cur'), pointer; } <![endif]-->

• Using JavaMail to send a mail containing Unicode characters

When the email arrives (in another GMail account), the euro symbol has been converted to the ASCII '?' question mark. I don't know much about emails: can email use any character encoding? What should I modify in the code above so that an encoding allowing Unicode characters is used?

• What's the next steps for moving from appengine to full django?

  - by tomcritchlow

  Hey guys, I'm super new to programming and I've been using appengine to help me learn python and general coding. I'm getting better quickly and I'm loving it all the way :) Appengine was awesome for allowing me to just dive into writing my app and getting something live that works (see http://www.7bks.com/). But I'm realising that the longer I continue to learn on appengine the more I'm constraining myself and locking myself into a single system. I'd like to move to developing on full django (since django looks super cool!). What are my next steps? To give you a feel for my level of knowledge: I'm not a unix user I'm not familiar with command line controls (I still use appengine/python completely via the appengine SDK) I've never programmed in anything other than python, anywhere other than appengine I know the word SQL, but don't know what MySQL is really or how to use it. So, specifically: What are the skills I need to learn to get up and running with full django/python? If I'm going to host somewhere else I suppose I'll need to learn some sysadmin type skills (maybe even unix?). Is there anywhere that offers easy hosting (like appengine) but that supports django? I hear such great things about heroku I'm considering switching to RoR and going there I appreciate that I'm likely not quite ready to move away from appengine just yet but I'm a fiercely passionate learner (http://www.7bks.com/blog/179001) and would love it if I knew all the steps I needed to learn so I could set about learning them. At the moment, I don't even know what the steps are I need to learn! Thank you very much. Sorry this isn't a specific programming question but I've looked around and haven't found a good how-to for someone of my level of experience and I think others would appreciate a good roadmap for the things we need to learn to get up and running. Thanks, Tom PS - if anyone is in London and fancies showing me the ropes in person that would be super awesome :)

• Castle windsor security exception

  - by Sunil

  I developed a small WCF service that uses Castle Windsor IoC container and it works fine on my PC. When I deploy it onto a Win 2008 R2 server and host the WCF service in IIS 7 it fails with the following error. I checked the server level web.config and the trust level is set to "Full". What do I need to do to get this to work. As a test I deployed the same service as it is onto a Windows 2003 server with the trust level set to "Full" and it works fine. I am unable to figure out what setting/configuration I am missing on the 2008 server that is making the service fail.

• Apache Content negotiation returns wrong Content-Type with Mulitviews :(

  - by edbras

  I am using Apache webserver 2.2 with Content Negotiation through Multiviews. I have: <Directory /home/develop/web/prodBuild> Options +MultiViews AddEncoding x-gzip .gz </Directory> This directory contains the gzip files. So if a browser requests the file bla.js, the server will return the file bla.js.gz as the file bla.js doesn't exists. However, the Content-Type on my Ubuntu server is set to be "application/x-gzip" which is wrong as it's a javascript file, so is has be "application/javascript" I have this working on my local Windows Apache server, but don't seem to get it working on the remote Ubuntu server. :(... NO idea why... Who/why is it setting this wrong Content-Type ? BTW: I don't have this line "AddType application/x-gzip .gz .tgz" somwhere in my config, as then I understand why it goes wrong. My workaround: add the following line under the above "AddEncoding": AddType "" .gz It will then set an empty string as Content-Type and then it works.. I think that the browser will try to discover the content type itself... I hope somebody can explain to me why this is not working and why this content type is set ? :(

• How do I make a serialization class for this?

  - by chobo2

  I have something like this (sorry for the bad names) <root xmlns="http://www.domain.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.Domain.com Schema.xsd> <product></product> <SomeHighLevelElement> <anotherElment> <lowestElement> </lowestElement> </anotherElment> </SomeHighLevelElement> </root> I have something like this for my class public class MyClass { public MyClass() { ListWrapper= new List<UserInfo>(); } public string product{ get; set; } public List<SomeHighLevelElement> ListWrapper{ get; set; } } public class SomeHighLevelElement { public string lowestElement{ get; set; } } But I don't know how to write the code for the "anotherElement" not sure if I have to make another wrapper around it. Edit I know get a error in my actual xml file. I have this in my tag xmlns="http://www.domain.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.Domain.com Schema.xsd Throws an exception on the root line saying there was a error with this stuff. So I don't know if it is mad at the schemaLocation since I am using local host right now or what.

• How do you organise multiple git repositories?

  - by dbr

  With SVN, I had a single big repository I kept on a server, and checked-out on a few machines. This was a pretty good backup system, and allowed me easily work on any of the machines. I could checkout a specific project, commit and it updated the 'master' project, or I could checkout the entire thing. Now, I have a bunch of git repositories, for various projects, several of which are on github. I also have the SVN repository I mentioned, imported via the git-svn command.. Basically, I like having all my code (not just projects, but random snippets and scripts, some things like my CV, articles I've written, websites I've made and so on) in one big repository I can easily clone onto remote machines, or memory-sticks/harddrives as backup. The problem is, since it's a private repository, and git doesn't allow checking out of a specific folder (that I could push to github as a separate project, but have the changes appear in both the master-repo, and the sub-repos) I could use the git submodule system, but it doesn't act how I want it too (submodules are pointers to other repositories, and don't really contain the actual code, so it's useless for backup) Currently I have a folder of git-repos (for example, ~/code_projects/proj1/.git/ ~/code_projects/proj2/.git/), and after doing changes to proj1 I do git push github, then I copy the files into ~/Documents/code/python/projects/proj1/ and do a single commit (instead of the numerous ones in the individual repos). Then do git push backupdrive1, git push mymemorystick etc So, the question: How do your personal code and projects with git repositories, and keep them synced and backed-up?
