• iphone application ad-hoc installation on windows gives invalid certificate error

  - by Lorenzo Boccaccia

  I've an application that need to be deployed to some testers. those with windows machine are reporting that the certificate used for signing the application couldn't be installed because of an unknown critical extension (1.2.840.113635.100.6.1.4) is there a way to make that critical extension known to windows (vista 64bit specifically)? I'm guessing that all this system of extension give user the ability to register callbacks to interpret the various added extensions (it would be totally useless otherwise)

• Nginx proxy to s3 bucket gets 400 Invalid Argument

  - by elssar

  I have a Django app in which I serve media files through an nginx proxy to s3. The relevant python code response = HttpResponse() response['X-Accel-Redirect'] = '/s3_redirect/%s' % filefield.url.replace('http://', '') response['Content-Disposition'] = 'attachment; filename=%s' % filefield.name return response The nginx block for the internal redirect is location ~* ^/s3_redirect/(.*) { internal; set $full_url http://$1; proxy_pass $full_url; And the request logged by s3 is. REST.GET.OBJECT <media file> "GET <media file>" 400 InvalidArgument 354 - 4 - "http://<referer>" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_3) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1" - I, for the life of me, can't figure out what's wrong. The url send to nginx by the app is valid, it works in the browser. And nginx is sending a request to s3.

• bind: blackhole for invalid recursive queries?

  - by Udo G

  I have a name server that's publicly accessible since it is the authoritative name server for a couple of domains. Currently the server is flooded with faked type ANY requests for isc.org, ripe.net and similar (that's a known distributed DoS attack). The server runs BIND and has allow-recursion set to my LAN so that these requests are rejected. In such cases the server responds just with authority and additional sections referring the root servers. Can I configure BIND so that it completely ignores these requests, without sending a response at all?

• Foremost custom file type not accepted by -t argument

  - by Channel72

  I'm trying to recover a deleted file on an ext3 file system using the foremost utility. The file I want to recover is a hpp C++ source code file. However, foremost does not automatically support the hpp file extension, so I have to add it to the config file. So, following the instructions on the man page, I add the following line to the config file: hpp n 50000 include include ASCII Then I run foremost as follows: $foremost -v -T -t hpp -i /dev/md0 -o /home/recover/ Instead of doing anything, it just displays the help message. If I change the hpp to htm or jpg, it works. So apparently foremost isn't accepting the custom file type I added into the config file. But I've looked over this dozens of times now, and I can't see what I'm doing wrong. I'm following the instructions exactly. Why doesn't foremost recognize the new file type I added to the config file?

• Unable to remove invalid(orphaned?) SPNs

  - by Brent

  tldr version: Renamed domain from internal.domain.com to domain.com, have 4 SPNs that am unable to remove from DC. So my domain was internal.domain-name.com and I renamed it to domain-name.com and I thought everything was good.

• How to know that my IP is invalid

  - by PeterMmm

  I have a script running that will start up an interface with a new IP. If the script comes up with an IP that is already in use i am in trouble. Is it possible that the script set up the new Ip, detects that this IP is already in use and then check the next one, until it finds an ip that works ? B=192.168.1. I=1 while [ "$I" != "256" ] do ifconfig eth0:1 $B.$I # check here that IP is Ok ! let "I=I+1" done

• Renaming an Invalid Filename in NTFS

  - by Sadeq Dousti

  Recently, I loaned my flash disk to one of my friends, who had Mac OS. He copied a file on it, whose name included a backslash (\). The flash disk is NTFS formatted. Windows does not allow such filenames, and neither opens the file, nor deletes it, nor lets me delete the file. There are naive approaches to this problem, like: Formatting the flash disk; Giving it back to my friend and asking to rename it; Loading into some live Linux and renaming it. However, I'm looking for something more clever, like a program that can do the trick under Windows. PS: There's a tool called NTFSWalker which can browse the MFT records of the NTFS, but is unable to make any changes to them.

• Invalid user names when creating a LDAP account

  - by h1d

  I'm trying to set up a system where a visitor can enter any user name in a form to create a new user and in the end it gets built on LDAP directory and I'm planning that to be mapped as a UNIX account as well (on Ubuntu Linux) by making the system look up for system accounts on the LDAP. Doing so is fine, but I feel that many user names should be avoided, one of the obvious being 'root' and all the other user names taken for daemons etc. How do you tackle at this problem? Do you make up a list of disallowed user names by checking /etc/passwd? I was thinking that if, internally, the user names could be prepended as 'ldap_' or something, it will avoid any naming conflicts but that seems hard when the LDAP entry name is 'joe' but the system account will look like 'ldap_joe'. Not even sure how that can be achieved.

• emacs does not open a file from argument and syntax highlight does not work

  - by Jus

  In my latest ubuntu box, When I type for example emacs ~/.bashrc, Emacs will start but not open .bashrc. This is true for any file I pass in. I've used Emacs for several years, and have never experienced this problem before. I added (global-font-lock-mode 1);; to my .emacs file, and Emacs does recognize it, for example. "(C++/; Abbrev)", but it won't do syntax highlighting. If you can solve any of these problems, it will be very appreciated. The following is my machine's configuration: uname -a Linux 2.6.35-28-generic-pae #49-Ubuntu SMP Tue Mar 1 14:58:06 UTC 2011 i686 GNU/Linux ~/.emacs (global-font-lock-mode 1);;

• Passing an array argument from Excel VBA to a WCF service

  - by PrgTrdr

  I'm trying to pass an array as an argument to my WCF service. To test this using Damian's sample code, I modified GetData it to try to pass an array of ints instead of a single int as an argument: using System; using System.ServiceModel; namespace WcfService1 { [ServiceContract] public interface IService1 { [OperationContract] string GetData(int[] value); [OperationContract] object[] GetSomeObjects(); } } using System; namespace WcfService1 { public class Service1 : IService1 { public string GetData(int[] value) { return string.Format("You entered: {0}", value[0]); } public object[] GetSomeObjects() { return new object[] { "String", 123, 44.55, DateTime.Now }; } } } Excel VBA code: Dim addr As String addr = "service:mexAddress=""net.tcp://localhost:7891/Test/WcfService1/Service1/Mex""," addr = addr + "address=""net.tcp://localhost:7891/Test/WcfService1/Service1/""," addr = addr + "contract=""IService1"", contractNamespace=""http://tempuri.org/""," addr = addr + "binding=""NetTcpBinding_IService1"", bindingNamespace=""http://tempuri.org/""" Dim service1 As Object Set service1 = GetObject(addr) Dim Sectors( 0 to 2 ) as Integer Sectors(0) = 10 MsgBox service1.GetData(Sectors) This code works fine with the WCF Test Client, but when I try to use it from Excel, I have this problem. When Excel gets to the service1.GetData call, it reports the following error: Run-time error '-2147467261 (80004003)' Automation error Invalid Pointer It looks like there is some incompatibility between the interface specification and the VBA call. Have you ever tried to pass an array from VBA into WCF? Am I doing something wrong or is this not supported using the Service moniker?

• Flickr 'Invalid auth token (98)' Uploading videos from Asp.net Application

  - by pat8719

  I am attempting to allow user to upload videos to Flickr from an Asp.net application using the FlickrNet library/API. I've obtained an API key and an API secret from Flickr. Additionally I am retrieving an authToken using the AuthGetFrob method from the FlickrNet library. My Using Statements are as Follows using System; using System.Collections.Generic; using System.Linq; using System.Text; using FlickrNet; I have created two methods to accomplish this task. One which gets and returns the AuthToken private string GetAuthenticateToken() { Flickr flickr = new Flickr(FLICKR_API_KEY, FLICKR_API_SECRET); string frob = flickr.AuthGetFrob(); return flickr.AuthCalcUrl(frob, AuthLevel.Write); } And One the Uploads the File Using that AuthToken public void UploadFile(string fileName, string title, string description) { try { string authToken = GetAuthenticateToken(); Flickr flickr = new Flickr(FLICKR_API_KEY, FLICKR_API_SECRET, authToken); string photoId = flickr.UploadPicture(fileName, title, description, "", true, false, false); } catch (Exception ex) { throw ex; } } However, when I make the call to 'UploadPicture' the following exception is thrown. 'Invalid auth token (98)'. The contents of the AuthRequest Http request looks like this. <?xml version="1.0" encoding="utf-8" ?> <rsp stat="ok"> <frob>72157627073829842-9d8e31b9dcf41ea1-162888</frob> </rsp> And the content of the Upload methods Http request looks like this. <?xml version="1.0" encoding="utf-8" ?> <rsp stat="fail"> <err code="98" msg="Invalid auth token" /> </rsp> I saw a similar post on the flickr forums here but based on my understanding, it appears that I am doing everything right yet still cannot figure what I am doing wrong. Any help would be greatly appreciated.

• Boost.Program_Options not working with short options

  I have the following options_description: po::options_description config("Configuration File or Command Line"); config.add_options() ("run-time,t", po::value(&runTime_)-default_value(1440.0), "set max simulation duration") ("starting-iteration,i", po::value(&startingIteration_)-default_value(1), "set starting simulation iteration") ("repetitions,r", po::value(&repetitions_)-default_value(100), "set number of iterations") ... ; As you can see the three shown have a long,short names employed. The long versions all work. However, none of the short ones do, and each time I try a -t 12345.0 or a -i 12345, etc., I get the following from Program_Options: std::logic_error: in option 'starting-iteration': invalid option value I'm using Boost 1.42 on Win32. Any thoughts on what might be going on here? Thanks!

• Paypal sandbox account in dotnet: "IPN Response invalid"

  I am integrating Paypal with my website. I use a sandbox account, one buyer account and one seller account. I downloaded the code below from Paypal: string strSandbox = "https://www.sandbox.paypal.com/cgi-bin/webscr"; HttpWebRequest req = (HttpWebRequest)WebRequest.Create(strSandbox); //Set values for the request back req.Method = "POST"; req.ContentType = "application/x-www-form-urlencoded"; byte[] param = Request.BinaryRead(HttpContext.Current.Request.ContentLength); string strRequest = Encoding.ASCII.GetString(param); strRequest += "&cmd=_notify-validate"; req.ContentLength = strRequest.Length; //for proxy //WebProxy proxy = new WebProxy(new Uri("http://url:port#")); //req.Proxy = proxy; //Send the request to PayPal and get the response StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII); streamOut.Write(strRequest); streamOut.Close(); StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream()); string strResponse = streamIn.ReadToEnd(); streamIn.Close(); if (strResponse == "VERIFIED") { //check the payment_status is Completed //check that txn_id has not been previously processed //check that receiver_email is your Primary PayPal email //check that payment_amount/payment_currency are correct //process payment } else if (strResponse == "INVALID") { //log for manual investigation } else { //log response/ipn data for manual investigation } When I add this snippet in my pageload event of my success page, I show the IPN response as INVALID, but amount is paid successfully. Why is this? Paypal's docs are not clear.

• Invalid iPhone Application Binary

  - by Kristopher Johnson

  I'm trying to upload an application to the iPhone App Store, but I get this error message from iTunes Connect: The binary you uploaded was invalid. The signature was invalid, or it was not signed with an Apple submission certificate. My guess is that it is not properly signed. I have downloaded my App Store distribution certficate, but I can't figure out how to "sign" my application with it. The SDK's documentation about code signing is not very helpful. (FWIW, I can install the app on my iPhone just fine using the development provisioning profile.) However, it is possible that I screwed things up on a more basic level. Here's what I did to try to prepare it for upload: In Xcode, select the Device|Release target Select the target and click the Info button. Change "Code Signing Identity" to "iPhone Distribution", and change "Code Signing Provisioning Profile" to my App Store distribution profile. Build Go to the directory where the built MyApp.app bundle is, control-click and choose "Compress" to create MyApp.zip Upload MyApp.zip to the App Store via iTunes Connect (which resulted in the above error message). Can anybody give me any hints? Edit: Found someone with the same problem. Unfortunately, he won't tell us how he fixed it. http://www.rhonabwy.com/wp/2008/07/18/seattlebus-diary-ongoing-update-saga/#comments http://www.rhonabwy.com/wp/2008/07/22/seattlebus-diary-update-is-pending-review/ (Note: For general information on submitting iPhone applications to the App Store, see Steps to upload an iPhone application to the AppStore.)

• Expression Tree with Property Inheritance causes an argument exception

  - by Adam Driscoll

  Following this post: link text I'm trying to create an expression tree that references the property of a property. My code looks like this: public interface IFoo { void X {get;set;} } public interface IBar : IFoo { void Y {get;set;} } public interface IFooBarContainer { IBar Bar {get;set;} } public class Filterer { //Where T = "IFooBarContainer" public IQueryable<T> Filter<T>(IEnumerable<T> collection) { var argument = Expression.Parameter(typeof (T), "item"); //... //where propertyName = "IBar.X"; PropertyOfProperty(argument, propertyName); } private static MemberExpression PropertyOfProperty(Expression expr, string propertyName) { return propertyName.Split('.').Aggregate<string, MemberExpression>(null, (current, property) => Expression.Property(current ?? expr, property)); } } I receive the exception: System.ArgumentException: Instance property 'X' is not defined for type 'IBar' ReSharper turned the code in the link above into the condensed statement in my example. Both forms of the method returned the same error. If I reference IBar.Y the method does not fail.

• What's the boost way to create a functor that binds out an argument

  - by Mordachai

  I have need for a function pointer that takes two arguments and returns a string. I would like to pass an adapter that wraps a function that takes one argument, and returns the string (i.e. discard one of the arguments). I can trivially build my own adapter, that takes the 2 arguments, calls the wrapped function passing just the one argument through. But I'd much rather have a simple way to create an adapter on the fly, if there is an easy way to do so in C++/boost? Here's some details to make this a bit more concrete: typedef boost::function<CString (int,int)> TooltipTextFn; class MyCtrl { public: MyCtrl(TooltipTextFn callback = boost::bind(&MyCtrl::GetCellText, this, _1, _2)) : m_callback(callback) { } // QUESTION: how to trivially wrapper GetRowText to conform to TooltipTextFn by just discarding _2 ?! void UseRowText() { m_callback = boost::bind(&MyCtrl::GetRowText, this, _1, ??); } private: CString GetCellText(int row, int column); CString GetRowText(int row); TooltipTextFn m_callback; } Obviously, I can supply a member that adapts GetRowText to take two arguments and only passes the first to GetRowText() itself. But is there already a boost binder / adapter that lets me do that?

• What makes this "declarator invalid"? C++

  I have Vertex template in vertex.h. From my graph.h: 20 template<class edgeDecor, class vertexDecor, bool dir> 21 class Vertex; which I use in my Graph template. I've used the Vertex template successfully throughout my Graph, return pointers to Vertices, etc. Now for the first time I am trying to declare and instantiate a Vertex object, and gcc is telling me that my 'declarator' is 'invalid'.

• activemerchant PayPalExpress transaction is invalid

  - by Ameya Savale

  I am trying to integrate activemerchant into my ruby on rails application. This is my controller where I get the purchase attirbutes and create a PaypalExpressResponse object def checkout total_as_cents, purchase_params = get_setup_params(Schedule.find(params[:schedule]), request) setup_response = @gateway.setup_purchase(total_as_cents, purchase_params) redirect_to @gateway.redirect_url_for(setup_response.token) end @gateway is my PaypalExpressGateway object which I create using this method in my controller def assign_gateway @gateway = PaypalExpressGateway.new( :login => api_user, :password => api_pass, :signature => api_signature ) end I got the api_user, api_pass, and api_signature values from my developer.paypal.com account, when I logged in for the first time there was already a sandbox user created as a merchant which is where I got the api credentials from. And finally here is my get_setup_params method: def get_setup_params(schedule, request) purchase_params = { :ip => request.remote_ip, :return_url => url_for(:action => 'review', :only_path => false, :sched => schedule.id), :cancel_return_url => register_path, :allow_note => true, :item => schedule.id } return to_cents(schedule.fee), purchase_params end How ever when I click on the checkout button, I get redirected to a sandbox paypal page saying "This transaction is invalid. Please return to the recipient's website to complete your transaction using their regular checkout flow." I'm not sure exactly what's wrong, I think the problem lies in the credentials but don't know why. Any help will be appreciated. One other point, I'm running this in my development environment so I have put this in my config file config.after_initialize do ActiveMerchant::Billing::Base.mode = :test end UPDATE Found out what the problem was, my return cancel url was invalid instead of using register_path, I used url_for(action: "action-name", :only_path => false) this answer helped me Rails ActiveMerchant - Paypal Express Checkout Error even though I wasn't able to see the output of the response like the person has managed to do

".`blog` SET `title` = '{$title}', `story` = '{$story}' WHERE `id` = {$bId}"; $r = mysql_query($q, $connection); if (mysql_affected_rows() == 1) { //Successful $data['success'] = true; $date['errors'] = false; $date['message'] = "You are the Greatest!"; } else { //Fail $data['success'] = false; $data['error'] = true; $date['message'] = "You can't do it fool!"; } } I also get an "mysql_num_rows(): supplied argument is not a valid MySQL result resource" error too. Side notes: I am using 1&1 Hosting (worst hosting ever), custom .htaccess file with one line text to enable PHP 5.2 (only why with 1&1 Hosting).
