• Changing Domain Name DNS to Redirect web traffic to one server, and leave mail to original server

  - by David S

  Hi there, Ok, quite the idiot with DNS.. apart from the basics. I have a domain name hosted with a domain registrar. It seems to have full DNS control (i.e. ability to view/edit A Records, Mail etc..) We have recently setup a server at Rackspace which hosts the new website The original/existing server (where the old website still is and Mail) is on another shared hosting companies server I went to the domain name registrar, and checked out the DNS management as follows: click here to view the DNS screenshot So obviously the A Record is pointing to the actual server where the website/mail is I figure, and the CNAME is pointing (alias?) to the website url. So my question is this: If I want the web traffic portion to go to the Rackspace/new server, but keep the mail going to where it is now, what do I have to change? Also, should I even change this info at the domain registrar? the rackspace server account has full DNS which seems to suggest I can point to their nameservers and then re-direct the MX (Mail) traffic to where the mail server is? Sorry if that was a bit confusing.. obviously in need of DNS training ;) Any help very appreciated. David.

• DNS NAmeserver Aname and cname records

  - by David

  Hi - I am inexperienced in the configuration of DNS and have an issue with dominan hosting set up. I have two domains 'www.mydomain1.com' and 'www.mydomain2.com', with mydomain2 pointed at the same place as mydomain1. The domains were passed to me recently by the person who previoulsy controlled them. I have an account with fasthosts in the uk. When I accepted the domains I could not access the DNS settings and enquired with fasthosts as to why. The replied saying 'The delegate hosting option for both domains were enabled and this is the reason why you were unable to find the option to edit the advanced DNS records. I have now disabled the delegate hosting option so you can now edit the advanced DNS records for both domains in your account.' When i log into the fasthost control panel now i can access the DNS controls but both domains have no A Record of Cname record set up. I am concerned that fasthosts have blatted the previous Nameserver entries and set me up on theirs but not added any record. 'www.mydomain1.com' currently still works but 'www.mydomain2.com' does not find the site anymore. i am worried i will lose mydomain1 to as teh dns changes filter through the system. my webhosting is at 'xxx.xxx.xxx.xxx/mydomain1.com/' and this is where I want both domains to point. Any advice would be much appreciated. one thing which is confusing me is that because I am on a shared server I have to put 'xxx.xxx.xxx.xxx/mydomain1.com/' to get to my site rather than just 'xxx.xxx.xxx.xxx'. The form on fasthosts for the aname record only allows an IP to be entered - does it add the mydomain1.com/ onto the end itself? Thanks for any help given - I'm quite worried about this David

• Running multiple sites on a LAMP with secure isolation

  - by David C.

  Hi everybody, I have been administering a few LAMP servers with 2-5 sites on each of them. These are basically owned by the same user/client so there are no security issues except from attacks through vulnerable deamons or scripts. I am builing my own server and would like to start hosting multiple sites. My first concern is... ISOLATION. How can I avoid that a c99 script could deface all the virtual hosts? Also, should I prevent that c99 to be able to write/read the other sites' directories? (It is easy to "cat" a config.php from another site and then get into the mysql database) My server is a VPS with 512M burstable to 1G. Among the free hosting managers, is there any small one which works for my VPS? (which maybe is compatible with the security approach I would like to have) Currently I am not planning to host over 10 sites but I would not accept that a client/hacker could navigate into unwanted directories or, worse, run malicious scripts. FTP management would be fine. I don't want to complicate things with SSH isolation. What is the best practice in this case? Basically, what do hosting companies do to sleep well? :) Thanks very much! David

• Facebook Graph API - authorization types?

  - by Alex Cook

  I'm struggling with the new Facebook Graph API, perhaps someone here can help. Here is what I want to do: provide a ‘login w/ FB’ button, throw to /authorize, get a code, throw to /access_token, get an access_token, and be able to hit https://graph.facebook.com/me for info about the user. When I try to use type=client_cred in the /authorize call, I get an access_token that lets me hit URLs with userIDs or names, but not /me. I receive an error stating I need a valid token. If I can't hit /me, how do I figure out who the current user is? What exactly should I use in the type param if I want a website to access a users data? I've seen posts with type=web_server, etc, but I can't seem to find a sure fire way to do, what I think, is pretty simple... Thanks ahead of time for any help thats provided...

• Cookies not sent in WebBrowser? (C#, VS2008)

  - by Ivan

  Hi, I'm trying to add cookies to a webbrowser from a cookiecollection. I add them as they should be added but then they are not sent when the request is done. Here is the code I have done hitherto: public void myNav(string url, CookieCollection cc) { foreach (Cookie cook in cc) { webBrowser1.Document.Cookie = cook.ToString(); } this.webBrowser1.Navigate(url); Clipboard.SetText(webBrowser1.Document.Cookie); } If I copy the cookies to the clipboard they are sent correctly, but If I analyse the request with Wireshark they are not sent in the headers. How can I solve this? Thanks in advance, Ivan

• “Could not create the file”, “Access is denied” and “Unrecoverable build error” in building setup project in VS 2008

  - by Mister Cook

  When building a setup project I get a message: Error with setup build: Error 27 Could not create the file 'C:\Users\MyName\AppData\Local\Temp\VSI1E1A.tmp' 'Access is denied.' I have tried the following (from http://support.microsoft.com/kb/329214/EN-US) regsvr32 "C:\Program Files (x86)\Common Files\Microsoft Shared\MSI Tools\mergemod.dll" The DLL registers but this does not fix my problem. Also, I tried a Clean build, deleting the temp folder, ran VS2008 as administratror, restart my PC but it occurs every time. I have no anti-virus software running and running on Windows 7 64-bit. This operation worked fine until recently. I have read many other users see this but found no solution. The only half solution I found was to edit setup properties and switch to Package files as Loose uncompressed files. This works but is not ideal as I need a full installer.

• Facebook access_token invalid?

  - by Alex Cook

  I'm attempting to use the new Graph API Facebook recently released, but I can't seem to get it to work correctly. I've gone through the steps, and after the /authorize call, I receive an access_token: access_token=109002049121898|nhKwSTJVPbUZ5JYyIH3opCBQMf8. When I attempt to use that token I get: { "error": { "type": "QueryParseException", "message": "An active access token must be used to query information about the current user." } } I'm stumped as too why... -AC

• Why does xdebug crash apache on every XAMPP install I've tried?

  - by Ian Cook

  I've installed the Windows XAMPP package on three separate computers, 2 running Windows Vista 32 bit ( 1 Ultimate / 1 Home Premium ) and 1 running Windows Vista 64 Home Premium. After enabling xdebug in php.ini and restarting apache, viewing the default XAMPP localhost index causes apache to crash in the same way every time, reporting 'php_xdebug.dll' as the Fault Module Name. Here's the full report from the Windows Crash Reporter thing: Problem signature: Problem Event Name: APPCRASH Application Name: apache.exe Application Version: 2.2.9.0 Application Timestamp: 4853f994 Fault Module Name: php_xdebug.dll Fault Module Version: 2.0.3.0 Fault Module Timestamp: 47fcd9b9 Exception Code: c0000005 Exception Offset: 00008493 OS Version: 6.0.6001.2.1.0.768.3 Locale ID: 1033 Additional Information 1: a34a Additional Information 2: c9c5f4fd744690d388ab9d5b3eb051a7 Additional Information 3: cb2e Additional Information 4: 650bb5690556a17e911375b94d3e16f0 I've tried Googling this issue but haven't found any resolution, only reports of similar errors. EDIT: I enabled the extension line for php_xdebug.dll and that seems to have stopped the crashing so far.

• PageMethod with Custom Handler

  - by Mister Cook

  I have a page based web method which works fine, using [WebMethod], i.e [WebMethod] public static void DoSomethingOnTheServer() { } I also have a custom page handler to make SEO friendly URLs possible, e.g http://localhost/MySite/A_nice_url.ext = http://localhost/MySite/page.aspx?id=1 I am using Server.Transfer in my ProcessRequest handler to achieve this. This all works fine. Also, my page method works fine when the user requests the URL such as: http://localhost/MySite/page.aspx?id=1 However, when the user requests the custom handled URL, i.e. http://localhost/MySite/A_nice_url.ext The client reports that the PageMethod has been successfully completed, but it has not been called at all. I'm guessing it has something to do with my custom handler, so I have modified it to include PathInfo: public void ProcessRequest(HttpContext context) { // ... (code to determine id) ... // Transfer to the required page string actualPath = "~/page.aspx" + context.Request.PathInfo + "?id=" + determinedId; context.Server.Transfer(actualPath); } So now if a PageMethod is called, it will result in: http://localhost/MySite/page.aspx/DoSomethingOnTheServer?id=1 I'm wondering if this is the correct syntax for calling a PageMethod. When I try Server.Transfer reports: Error executing child request for /MySite/page.aspx/DoSomethingOnTheServer I've experimented with HttpContext.RewritePath but not sure how to actually make it perform the request. This does not seem to work, any ideas?

• Why does std queue not define a swap method specialisation

  - by Jamie Cook

  I've read that all stl containers provide a specialisation of the swap algorithm so as to avoid calling the copy constructor and two assignment operations that the default method uses. However, when I thought it would be nice to use a queue in some code I was working on I noticed that (unlike vector and deque) queue doesn't provide this method? I just decided to use a deque instead of a queue, but still I'm interested to know why this is?

• Boost binding a function taking a reference

  Hi all, I am having problems compiling the following snippet int temp; vector<int> origins; vector<string> originTokens = OTUtils::tokenize(buffer, ","); // buffer is a char[] array // original loop BOOST_FOREACH(string s, originTokens) { from_string(temp, s); origins.push_back(temp); } // I'd like to use this to replace the above loop std::transform(originTokens.begin(), originTokens.end(), origins.begin(), boost::bind<int>(&FromString<int>, boost::ref(temp), _1)); where the function in question is // the third parameter should be one of std::hex, std::dec or std::oct template <class T> bool FromString(T& t, const std::string& s, std::ios_base& (*f)(std::ios_base&) = std::dec) { std::istringstream iss(s); return !(iss >> f >> t).fail(); } the error I get is 1>Compiling with Intel(R) C++ 11.0.074 [IA-32]...

• url encoded forward slashes breaking my codeigniter app

  - by Ian Cook

  i’m trying to create a url string that works like this: /app/process/example.com/index.html so in other words, /app/process/$URL i then retrieve the url with $this->uri->segment(3); the forward slashes in the URL will of course be a problem accessing uri segments, so i’ll go ahead and url encode the URL portion: /app/process/example.com%2Findex.html .. but now I just get a 404 saying ... Not Found The requested URL /app/process/example.com/index.html was not found on this server. it appears that my url encoding of forward slashes breaks CI’s URI parser. what can i do to get around this problem?

• Send asapMail without reloading page using ajax

  - by Darren Cook

  Hi, I have a form that posts data to an aspMail file for delivery (works fine in current format), but would like to have the form data sent without having to re-direct to another page. Looks like Ajax is the way to proceed but I'm having a problem getting the setup to work. Here's how I've changed the html: Added: $('#myForm').submit(function() { $.ajax({ data: $(this).serialize(), type: $(this).attr('post'), url: $(this).attr('aspSend.asp'), success: function(response) { $('#created').html(response) } }); }); Changed the form tag from: <form name="myForm" action"aspSend.asp"> to: <form name="myForm"> but now the emails don't arrive!! Any suggestions?

• Determine if PowerShell function is running as part of a pipeline?

  - by Richard Cook

  Can a PowerShell function determine if it is being run as part of a pipeline? I have a function which populates an array with instances of FileInfo which I would like to "yield" to the pipeline if the function is being run this way or produce some pretty output if the function is being invoked by itself from the command line. function Do-Something { $file_infos = @() # Populate $file_infos with FileInfo instances... if (INVOKED_IN_PIPELINE) { return $file_infos } else { foreach ($file_info in $file_infos) { write-host -foregroundcolor yellow $file_info.fullname } } } Basically, I'm trying to figure out how to implement INVOKED_IN_PIPELINE. If it is run in a pipeline (e.g. Do-Something | format-table fullname), I would simply yield the array, but if run directly (e.g. Do-Something), it would simply pretty-print the output. Is there a way to do this? If there is a more "idiomatic" way to achieve this kind of thing, I would also be interested to know.

• Casting a container of shared_ptr

  - by Jamie Cook

  Hi all, I have a method void foo(list<shared_ptr<Base>>& myList); Which I'm trying to call with a two different types of lists, one of DerivedClass1 and one of DerivedClass2 list<shared_ptr<DerivedClass1>> myList1; foo(myList1); list<shared_ptr<DerivedClass2>> myList2; foo(myList2); However this obviously generates a compiler error error: a reference of type "std::list<boost::shared_ptr<Base>, std::allocator<boost::shared_ptr<Base>>> &" (not const-qualified) cannot be initialized with a value of type "std::list<boost::shared_ptr<DerivedClass1>, std::allocator<boost::shared_ptr<DerivedClass1>>>" Is there any easy way to cast a container of shared_ptr? Of alternate containers that can accomplish this?

• crash when using stl vector at instead of operator[]

  - by Jamie Cook

  I have a method as follows (from a class than implements TBB task interface - not currently multithreading though) My problem is that two ways of accessing a vector are causing quite different behaviour - one works and the other causes the entire program to bomb out quite spectacularly (this is a plugin and normally a crash will be caught by the host - but this one takes out the host program as well! As I said quite spectacular) void PtBranchAndBoundIterationOriginRunner::runOrigin(int origin, int time) const // NOTE: const method { BOOST_FOREACH(int accessMode, m_props->GetAccessModes()) { // get a const reference to appropriate vector from member variable // map<int, vector<double>> m_rowTotalsByAccessMode; const vector<double>& rowTotalsForAccessMode = m_rowTotalsByAccessMode.find(accessMode)->second; if (origin != 129) continue; // Additional debug constrain: I know that the vector only has one non-zero element at index 129 m_job->Write("size: " + ToString(rowTotalsForAccessMode.size())); try { // check for early return... i.e. nothing to do for this origin if (!rowTotalsForAccessMode[origin]) continue; // <- this works if (!rowTotalsForAccessMode.at(origin)) continue; // <- this crashes } catch (...) { m_job->Write("Caught an exception"); // but its not an exception } // do some other stuff } } I hate not putting in well defined questions but at the moment my best phrasing is : "WTF?" I'm compiling this with Intel C++ 11.0.074 [IA-32] using Microsoft (R) Visual Studio Version 9.0.21022.8 and my implementation of vector has const_reference operator[](size_type _Pos) const { // subscript nonmutable sequence #if _HAS_ITERATOR_DEBUGGING if (size() <= _Pos) { _DEBUG_ERROR("vector subscript out of range"); _SCL_SECURE_OUT_OF_RANGE; } #endif /* _HAS_ITERATOR_DEBUGGING */ _SCL_SECURE_VALIDATE_RANGE(_Pos < size()); return (*(_Myfirst + _Pos)); } (Iterator debugging is off - I'm pretty sure) and const_reference at(size_type _Pos) const { // subscript nonmutable sequence with checking if (size() <= _Pos) _Xran(); return (*(begin() + _Pos)); } So the only difference I can see is that at calls begin instead of simply using _Myfirst - but how could that possibly be causing such a huge difference in behaviour?

• Best Practice for Exporting an App's Data to XML via PHP/MySQL?

  - by Alex Cook

  I have an a business app and I want to give my users the ability to export their data at anytime. I'm aware that I can write an XML file semi-manually by doing something like this: http://www.kirupa.com/web/mysql_xml_php.htm But, I thought I'd ask if this is the best practice? Or is there some framework I can use to do this more easily/quickly? Maybe there isn't - it won't be too hard to do it the above way. Also, less importantly - XML is the best format to export to, right? Thanks in advance.

• Exchange Server 2010: move mailboxes from recoveded and mounted edb to user's mailbox [closed]

  - by Cook

  One of our exchange servers crashed, and I am trying to recover the mailboxes. We had 1 exchange 2003 server named "apex" and 1 exchange 2010 server named "2008Enterprise. the exchange 2010 server named "2008Enterprise" crashed. I created a new exchange 2010 server named "Providence". I ran the command on Providence: New-MailboxDatabase -Recovery -Name JBCMail -Server Providence -EdbFilePath "c:\data\Exchange\Mailbox\Mailbox Database 0579285147\Mailbox Database 0579285147.edb" -LogFolderPath "c:\data\Exchange\Mailbox\Mailbox Database 0579285147" this command executed and finished without error I then ran the command: eseutil /p E00 this command was executed from the below directory: c:\data\Exchange\Mailbox\Mailbox Database 0579285147 I then mounted the JBCMail with the mount command note: I do not have my full typed command. Inside my Exchange Management Console (EMC) I can view the new mailbox database named JBCMail. The JBCMail database is show as mounted on the exchange server named Providence. I can see the crashed Exchange server named 2008Exchange. In the EMC the crashed exchange server states the Copy Status under ServerConfiguration-Mailbox is ServiceDown. From here I need to recover three mailboxes The mail boxes are on the apex server. How do I move the mailboxs from apex to Providence? How do I restore the mailboxes from JBCmail mounted database to the user's mailbox? I do not fully understand how to use the Restore-Mailbox command because when I use this command it tries to restore the mailbox to the dead apex server.

• converting a form from text to textarea

  I have a form created to pull PHP values into my database. I created the form with all type="text" constructions. What follows is the code that used to set up the input of data and confirmed that it is functional. <label>About Me: <input type="text" name="BIO_info"/></label> I converted the input to a textarea and adjusted some parameters for proper display. Unfortunately, it has broken the ability for the script to function. What follows is the code I wrote to convert and store from a text area input. <label for="BIO_info" style=" margin-bottom: 500px; margin-top: 2000px; ">About Me: <textarea name="BIO_info" rows="20" cols="60" style="resize: none; overflow-y: hidden;vertical-align:middle;"></textarea> <p> I would appreciate any suggestions.

• Detect what is selected (highlighted) or clicked within an element on a page?

  - by Fog Cook

  How would one go about detecting what has been selected on a page in a browser? Example: Click, hold, select 3 words and 1 image on a page, release. Sub-question: How to detect what letter someone clicked on? Without using: A span injector breaking everything up OR a WYSIWYG plugin I'm hoping this isn't just a type of browser interaction you can't detect. There could be many uses, but my goal is a simple 'live' page editor, or at least a way to know what someone is clicking on/selecting aside from just the id of an element.
