  • One single page showing 3 requests (also printing the headers)

    - by Korcholis
    Someone in my studio designed a webpage some years ago, and now the client decided to change the server (he moved to a Linux Apache server running Gen2 SMP, 64 bits, PHP version 5.3.8, Standard MYSQL version 5). It suddenly started to do weird things. When clicking on a link that requires login, the page redirects you to the login page using header() function in PHP. Curiously, the page shows this: OK The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. HTTP/1.1 200 OK Date: Mon, 15 Oct 2012 17:27:32 GMT Server: Apache/2.2.22 (Unix) FrontPage/5.0.2.2635 X-Powered-By: PHP/5.3.8 Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Keep-Alive: timeout=5, max=399 Connection: Keep-Alive Transfer-Encoding: chunked Content-Type: text/html 232c Then the page itself, and then, another header: 0 1f4 OK The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. 0 What's most intriguing is that if you refresh the page or hit enter on the url, it loads correctly. I've been checking the logs, and it only blames of an inexisting favicon. I also checked the .htaccess, everything was correct (RewriteBase was / as intended, and the only stuff there is another rule that moves ^en/ requests to request?lang=en. Has anyone faced something like this? Edit: IE doesn't trigger these two headers. This is getting wierder.

  • Is it possible to run multiple mongod instances on a single set of database files

    - by 9point6
    We have large multi-gigabyte data sets on which we run very complex queries, for example { $or: [ { id: 30000001, ... }, { id: 30000005, ... }, ..., { id: 30001005, ... } ] } It seems that CPU is actually a bottleneck at this point, so I'd be advantageous to be able to run multiple mongod instances on the same set of database files. We've considered using replica sets to this end, but would prefer to not require the extra disk space simply for CPU reasons.

  • Iptables to lock down compromised server to a single ip

    - by ollybee
    I have a Linux server which is compromised, I can see nasty looking perl scripts executing with root privileges. I want to get some data off it before I wipe it. How can I block all inbound and outbound traffic except for my ip? It's a Centos server I assume i can do this with iptables? I'm aware a the server is rooted there is a possibility that attackers could have made changes on the server that would prevent this from working. Ill be testing to make sure and only have the server online for a couple of hours before it is nuked.

  • Multiple PCs - Single profile

    - by martixy
    Or how to create an AD(or similar) environment at home? So... I work in this big IT company(they have and AD environment ofc) and I've seen first hand how nice integration and log-in-from-anywhere(roaming?) profiles can be. So I wanna create the same setup at home, where I have 3 machines. Mostly logging in with the same profile and preserving the settings(things like UAC being off, a few group policies I've customized, things like that). How can I achieve something like this?

  • Launching multiple applications with a single command/script/shortcut

    - by Bill
    I realized a few days ago that every time I sit down at work, I do a few things after unlocking my computer. First, I open up Firefox, then I open up Chrome, then I log in to Digsby. I realized I could probably save repeating this daily by writing a small batch script to open up Firefox and Chrome , but I couldn't figure out how to make it work.. and since the whole effort is to save time I don't want to bash my head around in the windows command prompt to do it. I also tired this in powershell but ran in to a bunch of security nonsense. Is there a way to do this that I am missing? Bonus points if somebody has figured out how to manipulate Digsby via COM , scripting, or python =)

  • Can TFS 2010 be installed onto a single server and in a Workgroup (not AD)

    - by Pure.Krome
    Hi folks, currently, we're using TFS2010 at our office and we're about to move. Part of that move is a split of teams. Our team will get their own servers. So we need to build our own TFS server and add our current projects to that. Right now, our TFS server exists on TWO servers - one for TFS and one for our Continuous Integration .. i think that's a build controller or something. That really suxs for us - having TWO servers instead of one for all our source control. We love CI and how it works (after the massive massive pain it was to get our VS2010 solution to CI + web Deploy) ... but it does work. So - can we do this with ONE server? Also, we don't want to have an Active Directory. Will this also work?

  • Single web app, multiple web servers

    - by Ramakrishna
    I have a problem of load balancing. We developed a web app for nearly 1500 users. As the number of users increased we are unable to serve the requests in a timely manner. It takes around 10 to 20 seconds to load a page. Under heavy load it can take one minute to serve the page. We need to solve this situation so that each request is served in 2 or 3 seconds.

  • Single Sign on for RDS

    - by stumct
    I currently have an RDS farm which is used for running remote apps for a large group of users. When logging in these users must authenticate to the RDS web page to view their list of applications. Then they authenticate again upon clicking the application the require. How can I enable this to use the users current windows authentication so they do not have to log in at each step. Ideally since the user is logged in to their local machine with their windows account, they should not need to continuously authenticate.

  • Single ipv6 from /64 subnet

    - by PartyPete
    I have a newb question I'd like to ask. We have an dedicated server and we got an ipv6 /64 block. We want to use squid to make proxy and use those IP. And my question now is: Is it possible to use only one IP out of range? for example: let's say I have a range of IPs ffff:ffff::/64, and want to use only one address from it: ffff:ffff::1/128 or ffff:ffff::2/128 but whenever I set squid like this I always get from 'what is my ip' services whole subnet which is again ffff:ffff::. What I want to achieve is to get from those 'what is my ip' services to send me back IP ffff:ffff::1 (or 2 for that matter) Am I doing something wrong?

  • ASP.NET single quotes are converted to &#39;

    - by Monty
    Note: Most probably this will be a double question, but since I haven't found a clear answer, I'm asking it anyway. In ASP.NET I'd like to add some JavaScript to the onclick event of a CheckBox. I've simplified the case to this: <asp:CheckBox ID="TestCheckBox" runat="server" onclick="alert('test');" Text="Test" /> The resulting HTML is as follows: <input id="MainContainer_TestCheckBox" type="checkbox" name="ctl00$MainContainer$TestCheckBox" onclick="alert(&#39;test&#39;);" /><label for="MainContainer_TestCheckBox">Test</label> What particularly bothers me is that a single quote 'automatically' gets converted into '&#39;'. If I omit the onclick in the markup and assign it in Page_Load, the exact same results show in the HTML. protected void Page_Load(object sender, EventArgs e) { this.TestCheckBox.Attributes["onclick"] = "alert('test');"; } Anyone got a clue about what's happening? Or how to fix/ avoid it?

  • insert VBS variable within a single-quoted WMI query

    - by jiaoziren
    Hi all, I am really frustrated by the snippet below: Dim objFSO, varSrc, varDest, varExt Set objFSO = CreateObject("Scripting.FileSystemObject") varSrc = WScript.Arguments(0) varDest = WScript.Arguments(1) varExt = WScript.Arguments(2) If objFSO.FolderExists(varSrc) Then WScript.Echo varSrc strComputer = "." Set objWMIService = GetObject("winmgmts:" _ & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2") Set colMonitoredEvents = objWMIService.ExecNotificationQuery _ ("SELECT * FROM __InstanceCreationEvent WITHIN 10 WHERE " _ & "Targetinstance ISA 'CIM_DirectoryContainsFile' AND " _ & "TargetInstance.GroupComponent= " _ & "'Win32_Directory.Name=""c:\\\\kk ""'") Do Set objLatestEvent = colMonitoredEvents.NextEvent WScript.Echo objLatestEvent.TargetInstance.PartComponent Loop Else WScript.Echo "Bazinga" End If I tried to replace c:\\kk with varSrc however it seems impossible for WSH to recognize it in WMI query - not to mention it was within a single quote! I have tried chr(34) and it didn't work. Please help if possible. Much appreciated!

  • How to expose service contract interfaces with multiple inheritance in WCF service on single endpoin

    - by Vaibhav Gawali
    I have only simple data types in method signature of service (such as int, string). My service class implements single ServiceContract interface say IMathService, and this interface in turn inherits from some other base interface say IAdderService. I want to expose the MathService using interface contract IAdderService as a service on a single endpoint. However some of the clinet's which know about IMathService should be able to access the extra services provided by IMathService on that single endpoint i.e. by just typecasting IAdderService to IMathService. //Interfaces and classes at server side [ServiceContract] public interface IAdderService { [OperationContract] int Add(int num1, int num2); } [ServiceContract] public interface IMathService : IAdderService { [OperationContract] int Substract(int num1, int num2); } public class MathService : IMathService { #region IMathService Members public int Substract(int num1, int num2) { return num1 - num2; } #endregion #region IAdderService Members public int Add(int num1, int num2) { return num1 + num2; } #endregion } //Run WCF service as a singleton instace MathService mathService = new MathService(); ServiceHost host = new ServiceHost(mathService); host.Open(); Server side Configuration: <configuration> <system.serviceModel> <services> <service name="IAdderService" behaviorConfiguration="AdderServiceServiceBehavior"> <endpoint address="net.pipe://localhost/AdderService" binding="netNamedPipeBinding" bindingConfiguration="Binding1" contract="TestApp.IAdderService" /> <endpoint address="mex" binding="mexNamedPipeBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="net.pipe://localhost/AdderService"/> </baseAddresses> </host> </service> </services> <bindings> <netNamedPipeBinding> <binding name="Binding1" > <security mode = "None"> </security> </binding > </netNamedPipeBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="AdderServiceServiceBehavior"> <serviceMetadata /> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> </configuration> Client Side imeplementation: IAdderService adderService = new ChannelFactory<IAdderService>("AdderService").CreateChannel(); int result = adderService.Add(10, 11); IMathService mathService = adderService as IMathService; result = mathService.Substract(100, 9); Client side configuration: <configuration> <system.serviceModel> <client> <endpoint name="AdderService" address="net.pipe://localhost/AdderService" binding="netNamedPipeBinding" bindingConfiguration="Binding1" contract="TestApp.IAdderService" /> </client> <bindings> <netNamedPipeBinding> <binding name="Binding1" maxBufferSize="65536" maxConnections="10"> <security mode = "None"> </security> </binding > </netNamedPipeBinding> </bindings> </system.serviceModel> </configuration> Using above code and configuration I am not able to typecast IAdderService instnace to IMathService, it fails and I get null instance of IMathService at client side. My observation is if server exposes IMathService to client then client can safely typecast to IAdderService and vice versa is also possible. However if server exposes IAdderService then the typecast fails. Is there any solution to this? or am I doing it in a wrong way.

  • SSRS 2008 printing single page renders different for print

    - by user270437
    I have a problem with SSRS 2008 reports rendering differently on the reporting server than the way it renders when you print the report. I’m trying to figure out to print a single page and have the print show that same records as I see on the report on the screen. As a test, I created a simple report with no headers or footers and just added a Tablix table to display the records (no groupings). My data set for this test displays 2 ¼ pages of records when I deploy it to our reporting services server and run it. If I click the print Icon and preview the report is 2 ¾ pages. I haven’t found anything searching on this so it makes me think it is something simple I’m missing. A basically want the report to render the same records on each page in Report Manager as it does when it prints, how do I accomplish this? (In response to answer posted by Chris)…If that is the case then it is disappointing. Customers are accustomed to WYSIWYG and will have a hard time understanding that, I imagine we will be getting a lot of support calls. This still leaves an issue. I tried using print preview and could not find any way to single out a page. If I select a page up front to print, or preview it renders different so I get different records. And if I preview the entire document, I can only print the entire document. You mentioned the Excel render; we have customers that will want that also. The problem I have found with Excel exports is that even a basic report winds up merging some cells and that messes up sorting. I’m going to try your tip about grouping to see if I can get a clean export to a page. It would have been nice if they would have created a property for certain controls like the tablix table called “ExcelSheet”. Then all you would have to do is give it a name and it would create a new sheet for each control with a name, the name becoming the sheet title. Thanks for the information you supplied it is very useful as I’m new to SSRS. If you know how I can Preview in print render and select individual pages to print from the render let me know. Update 02/19/2010 After testing this more I now realize it is just a bad design of Report managers print driver or a limitation because it is server based. The options work differently than Windows apps drivers, But I did find a work around. Here is the test I performed comparing Excel to Report Manager. I bring up a report that will render more than 1 page when printed. I then export to Excel, in Excel I select print preview. I can navigate the pages in preview and then select a single page like page 3. I can then print just page 3 without leaving print preview and it prints just like it rendered. I cannot do this using print in report manager. If I select print preview in report manager then try to print while in preview it always prints the entire document. However if I close out of print preview, I can then select page 3 and print it as rendered. It is just one additional step once you know what to do, but it took some time to figure it out.

  • Android "single top" launch mode and onNewIntent method

    - by Rich
    I read in the Android documentation that by setting my Activity's launchMode property to singleTop OR by adding the FLAG_ACTIVITY_SINGLE_TOP flag to my Intent, that calling startActivity(intent) would reuse a single Activity instance and give me the Intent in the onNewIntent callback. I did both of these things, and onNewIntent never fires and onCreate fires every time. The docs also say that this.getIntent() returns the intent that was first passed to the Activity when it was first created. In onCreate I'm calling getIntent and I'm getting a new one every time (I'm creating the intent object in another activity and adding an extra to it...this extra should be the same every time if it was returning me the same intent object). All this leads me to believe that my activity is not acting like a "single top", and I don't understand why. To add some background in case I'm simply missing a required step, here's my Activity declaration in the manifest and the code I'm using to launch the activity. The Activity itself doesn't do anything worth mentioning in regards to this: in AndroidManifest.xml: <activity android:name=".ArtistActivity" android:label="Artist" android:launchMode="singleTop"> </activity> in my calling Activity: Intent i = new Intent(); i.putExtra(EXTRA_KEY_ARTIST, id); i.setClass(this, ArtistActivity.class); i.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); startActivity(i);

From here... fruits = Fruit.find(:all) ...how do I return an array of just Apples from the fruits array?

  • Overlapping matches with finditer() in Python

    - by Raphink
    Hi there, I'm using a regex to match Bible verse references in a text. The current regex is REF_REGEX = re.compile(r'(?<!\w)((?i)q(?:uote)?\s+)?((?:(?:[1-3]|I{1,3})\s*)?[A-Za-z]+)\.?(?:\s*(\d+)(?:[:.](\d+)(?:-(\d+))?)?)(?:\s+(?:(?i)(?:from\s+)|(?:in\s+)|(?P<lbrace>\())\s*(\w+)(?(lbrace)\)))?', re.UNICODE) This matches the following expressions fine: "jn 3:16": (None, 'jn', '3', '16', None, None, None), "matt. 18:21-22": (None, 'matt', '18', '21', '22', None, None), "q matt. 18:21-22": ('q ', 'matt', '18', '21', '22', None, None), "QuOTe jn 3:16": ('QuOTe ', 'jn', '3', '16', None, None, None), "q 1co13:1": ('q ', '1co', '13', '1', None, None, None), "q 1 co 13:1": ('q ', '1 co', '13', '1', None, None, None), "quote 1 co 13:1": ('quote ', '1 co', '13', '1', None, None, None), "quote 1co13:1": ('quote ', '1co', '13', '1', None, None, None), "jean 3:18 (PDV)": (None, 'jean', '3', '18', None, '(', 'PDV'), "quote malachie 1.1-2 fRom Colombe": ('quote ', 'malachie', '1', '1', '2', None, 'Colombe'), "quote malachie 1.1-2 In Colombe": ('quote ', 'malachie', '1', '1', '2', None, 'Colombe'), "cinq jn 3:16 (test)": (None, 'jn', '3', '16', None, '(', 'test'), "Q IIKings5.13-58 from wolof": ('Q ', 'IIKings', '5', '13', '58', None, 'wolof'), "This text is about lv5.4-6 in KJV only": (None, 'lv', '5', '4', '6', None, 'KJV'), but it fails to parse: "Found in 2 Cor. 5:18-21 ( Ministers": (None, '2 Cor', '5', '18', '21', None, None), because it returns (None, 'in', '2', None, None, None, None) instead. Is there a way to get finditer() to return all matches, even if they overlap, or is there a way to improve my regex so it matches this last bit properly? Thanks.

    I have the following classes: Project Person Person Developer Person Manager In the Project model I have added the following statements: has_and_belongs_to_many :people accepts_nested_attributes_for :people And of course the appropriate statements in the class Person. How can I add an Developer to a Project through the nested_attributes method? The following does not work: @p.people_attributes = [{:name => "Epic Beard Man", :type => "Developer"}] @p.people => [#<Person id: nil, name: "Epic Beard Man", type: nil>] As you can see the type attributes is set to nil instead of Developer.
