  • How would I / could I obtain an reasonably comprehensive list of domain names?

    - by Simon
    I know that domain names are constantly changing, and I know there are a lot of them, but there is clearly a region of the domain name space which is stable. How would I go about getting a list, even a very big one? Such a thing must logically exist, even if it is in a distributed form, because the web's DNS servers resolve names to IP addresses. So in theory if I could poll all the DNS servers in the world at a moment in time I would have the complete list of mapped names. Is there a practical way of doing that? As an aside, does anyone have any good estimates of how many domain names exist at the moment?

  • Which GPO is making my Domain Controller my clients' DNS server?

    - by Harry Muscle
    I maintain a small domain (about 20 clients) and we need to make some changes to the DNS server that's being used by the clients. All the clients have been hard coded to use the domain controller as their DNS. Since these are new machines, and I never changed their DNS settings, I'm guessing there must be a GPO that's causing them to use the domain controller as their DNS. Since we don't have any GPO other than the default one yet, it's got to be the default GPO, however, I have looked through all the GPO settings and none of them refer to anything related to DNS. So I'm wondering if there's anything else that might be causing this. Any help or advice is highly appreciated. Thanks, Harry

  • How do I add client computers to a Windows SBS 2008 domain?

    - by Jonas
    We have a LAN and the router is the DHCP server. We have a server with Windows SBS 2008, it has the IP address 192.168.1.2 while the router has the IP address 192.168.1.1. I have set "DNS Relay" on the router to 192.168.1.2. I have tried to add a client computer to the SBS domain by visiting http://connect from the client computer. But that page doesn't exist. I can visit http://192.168.1.2/ then the default startpage for IIS7 is shown. I'm logged in as a local Administrator on the computer that I tries to add to the domain. How do I add the client computer to the SBS 2008 domain? The router is an D-Link DFL 200, and I have now set the "DNS Relay" to "Use address of LAN interface" instead of a specific IP-address. But it doesn't work.

  • How do I update my servers' domain name for Reverse DNS?

    - by Jeff
    I'm updating my mail servers' rDNS and I think I have it all figured out except for one thing. When I installed my OS (Debian Etch), the installer asked me to enter the "domain name". Is the "domain name" updated by using the hostname command? If so, which config file(s) are updated when using the hostname command? If not, how do I change my servers' domain name? My current /etc/hosts: 127.0.0.1 localhost 67.228.178.164 mrspock.example-old.com mrspock My current /etc/hostname: mrspock $ hostname -f mrspock.example-old.com I need to update hostname -f to be mrspock.example-new.com.

  • One vs. many domain user accounts in a server farm

    - by mjustin
    We are in a migration process of a group of related computers (Intranet servers, SQL, application servers of one application) to a new domain. In the past we used one domain user account for every computer (web1, web2, appserver1, appserver2, sql1, sqlbackup ...) to access central Windows resources like network shares. Every computer also has a local user account with the same name. I am not sure if this is necessary, or if it would be easier to configure and maintain to use one domain user account. Are there key advantages / disadvantages of having one single user account vs. dedicated accounts per computer for this group of background servers? If I am not wrong, one advantage besides easier administration of the user account could be that moving installed applications and services around between the computers does not require a check of the access rights anymore. (Except where IP addresses or ports are used)

  • Which firewall ports do I need to open in order for a domain trust to work?

    - by Massimo
    I have two Active Directory domains in two different forests; each domain has two DCs (all of them Windows Server 2008 R2). The domains are also in different networks, with a firewall connecting them. I need to create a two-way forest trust between the two domains and forest. How do I configure the firewall to allow this? I found this article, but it doesn't explain very clearly which traffic is required between DCs, and which traffic (if any) in needed instead between domain computers in one domain and DCs for the other one. I'm allowed to permit all traffic between the DCs, but allowing computers in one network to access DCs in the other one would be a little more difficult.

  • If I let Google handle my emails for my domain, my Wordpress site won't send out emails anymore

    - by Fulvio
    Since I decided to let Google handle all my emails for my domain, while the domain is hosted on a 3rd party server, emails send out by a Wordpress installation no longer work. My supposition is that since all email is being routed to Google, my specific account on that server for that domain is unable to send out emails. I definitely wish to keep using google services for handling my emails since it comes with all the advantages connected to a Google account. However I need my Wordpress installation to send out administrative emails. I run my server with CPanel. How to configure that specific account and/or Wordpress to keep it able to send out emails? I don't need people to answer these emails sent out from server (eventually I might set a reply-to-address perhaps) thanks

  • Design in "mixed" languages: object oriented design or functional programming?

    - by dema80
    In the past few years, the languages I like to use are becoming more and more "functional". I now use languages that are a sort of "hybrid": C#, F#, Scala. I like to design my application using classes that correspond to the domain objects, and use functional features where this makes coding easier, more coincise and safer (especially when operating on collections or when passing functions). However the two worlds "clash" when coming to design patterns. The specific example I faced recently is the Observer pattern. I want a producer to notify some other code (the "consumers/observers", say a DB storage, a logger, and so on) when an item is created or changed. I initially did it "functionally" like this: producer.foo(item => { updateItemInDb(item); insertLog(item) }) // calls the function passed as argument as an item is processed But I'm now wondering if I should use a more "OO" approach: interface IItemObserver { onNotify(Item) } class DBObserver : IItemObserver ... class LogObserver: IItemObserver ... producer.addObserver(new DBObserver) producer.addObserver(new LogObserver) producer.foo() //calls observer in a loop Which are the pro and con of the two approach? I once heard a FP guru say that design patterns are there only because of the limitations of the language, and that's why there are so few in functional languages. Maybe this could be an example of it? EDIT: In my particular scenario I don't need it, but.. how would you implement removal and addition of "observers" in the functional way? (I.e. how would you implement all the functionalities in the pattern?) Just passing a new function, for example?

    Hi All, Scenario :- I have to call MYSQL stored procedure from PHP and do some operations ( around 15 commands ) on the database Problem :- I have to call stored procedure with 36 parameters.

  • PHP, jQuery and Ajax Object Orientation

    - by pastylegs
    I'm a fairly experienced programmer getting my head around PHP and Ajax for the first time, and I'm having a bit of trouble figuring out how to incorperate object oriented PHP into my ajax webapp. I have an admin page (admin.php) that will load and write information (info.xml) from an XML file depending on the users selection of a form on the admin page. I have decided to use an object (ContentManager.php) to manage the loading and writing of the XML file to disk, i.e : class ContentManager{ var $xml_attribute_1 ... function __construct(){ //load the xml file from disk and save its contents into variables $xml_attribute = simplexml_load_file(/path/to/xml) } function get_xml_contents(){ return xml_attribute; } function write_xml($contents_{ } function print_xml(){ } } I create the ContentManager object in admin.php like so <?php include '../includes/CompetitionManager.php'; $cm = new CompetitionManager() ?> <script> ...all my jquery </script> <html> ... all my form elements </html> So now I want to use AJAX to allow the user to retrieve information from the XML file via the ContentManger app using an interface (ajax_handler.php) like so <?php if(_POST[]=="get_a"){ }else if() } ... ?> I understand how this would work if I wasn't using objects, i.e. the hander php file would do a certain action depending on a variable in the .post request, but with my setup, I can't see how I can get a reference to the ContentManager object I have created in admin.php in the ajax_handler.php file? Maybe my understanding of php object scope is flawed. Anyway, if anyone can make sense of what I'm trying to do, I would appreciate some help!

  • Explore a COM Object in PHP

    - by shaiss
    What would be the proper way to explode a COM object for debugging? I have a 3rd party function that returns a multilevel object. The documentation is non existant, so I'd like to be able to echo everything out of the object or debug it in Komodo IDE. Komodo just says Object and nothing else. Maybe convert to array? I know some of the existing options such as $com->Status, but there are more variables returned that I'd like to know what they are.

  • python object AttributeError: type object 'Track' has no attribute 'title'

    - by ccwhite1
    I apologize if this is a noob question, but I can't seem to figure this one out. I have defined an object that defines a music track (NOTE: originally had the just ATTRIBUTE vs self.ATTRIBUTE. I edited those values in to help remove confusion. They had no affect on the problem) class Track(object): def __init__(self, title, artist, album, source, dest): """ Model of the Track Object Contains the followign attributes: 'Title', 'Artist', 'Album', 'Source', 'Dest' """ self.atrTitle = title self.atrArtist = artist self.atrAlbum = album self.atrSource = source self.atrDest = dest I use ObjectListView to create a list of tracks in a specific directory ....other code.... self.aTrack = [Track(sTitle,sArtist,sAlbum,sSource, sDestDir)] self.TrackOlv.AddObjects(self.aTrack) ....other code.... Now I want to iterate the list and print out a single value of each item list = self.TrackOlv.GetObjects() for item in list: print item.atrTitle This fails with the error AttributeError: type object 'Track' has no attribute 'atrTitle' What really confuses me is if I highlight a single item in the Object List View display and use the following code, it will correctly print out the single value for the highlighted item list = self.TrackOlv.GetSelectedObject() print list.atrTitle

  • Object Oriented Database - why most of the companies do not use them

    - by GigaPr
    Hi, I am pretty new to programming(just finished University). I have been thought in the last 4 years about Object Oriented development and the numerous advantages of this approach. My question is Isn't it easier to use a pure Object Oriented database in development applications? Why Object Oriented database are not as much diffuse as relational? From my point of view makes sense to use OO database, the latter will avoid the numerous construction necessary for the mapping of complex objects on the tables.

  • reinitializing javascript object's properties

    - by Pino
    In my Javascript drag and drop build app, a variety of buildings can be built. The specific characteristics of these are all saved in one object, like var buildings = { house: ['#07DA21',12,12,0,20], bank: ['#E7DFF2',16,16,0,3], stadium: ['#000000',12,12,0,1], townhall: ['#2082A8',20,8,0,1], etcetera } So every building has a number of characteristics, like color, size, look which can be called as buildings[townhall][0] (referring to the color). The object changes as the user changes things. When clicking 'reset' however, the whole object should be reset to its initial settings again to start over, but I have no idea how to do that. For normal objects it is something like. function building() {} var building = new building(); delete building; var building2 = new building(); You can easily delete and remake it, so the properties are reset. But my object is automatically initialized. Is there a way to turn my object into something that can be deleted and newly created, without making it very complicating, or a better way to store this information?

  • ASP.NET "Object reference not set..." error

    - by Roman
    Hi, I have a website written using ASP.NET. We have a development machine and a deployment server. The site works great on the development machine, but when is transfered (using simple FTP Upload) generates strange behavior. It starts working just fine, but after a while stops working and throws an exception "Exception: Object reference not set to an instance of an object.". The deal is that the absolute path of the website on the development machine is different than on the deployment server (and why should they be similar?) and the exact error is: Exception: Object reference not set to an instance of an object. at SOMEPROJECT_Objects.Player..ctor(Int32 PlayerID) in C:\inetpub\wwwroot\SOMEPROJECTSolution\ALLPROJECT\SOMEPROJECT_Objects\Player.cs:line 123 at SOMEPROJECT_GameLayer.M_Game.PlayerActiveGame(Int32 PlayerID) in C:\inetpub\wwwroot\SOMEPROJECTSolution\ALLPROJECT\SOMEPROJECT_GameLayer\M_Game.cs:line 85 at Web.getsms.Page_Load(Object sender, EventArgs e) in C:\inetpub\wwwroot\SOMEPROJECTSolution\ALLPROJECT\SOMEPROJECT-sms\Web\getsms.aspx.cs:line 59 The address that it is looking for is the address on the DEVELOPMENT machine, where as the site now resides on the deployment server. Any ideas why this happens would be appreciated. Thanks, Roman

  • Flash doesn't connect to socket even though policy allows it

    - by Bart van Heukelom
    In my Flash app, I'm connecting to my server like this: Security.loadPolicyFile("xmlsocket://example.com:12860"); socket = new Socket("example.com", 12869); socket.writeByte(...); ... socket.flush(); At port 12860 I'm running a socket policy server, which (according to this document) correctly serves up my policy like this: 00000000 3c 70 6f 6c 69 63 79 2d 66 69 6c 65 2d 72 65 71 <policy- file-req 00000010 75 65 73 74 2f 3e 00 uest/>. 00000000 3c 63 72 6f 73 73 2d 64 6f 6d 61 69 6e 2d 70 6f <cross-d omain-po 00000010 6c 69 63 79 3e 3c 73 69 74 65 2d 63 6f 6e 74 72 licy><si te-contr 00000020 6f 6c 20 70 65 72 6d 69 74 74 65 64 2d 63 72 6f ol permi tted-cro 00000030 73 73 2d 64 6f 6d 61 69 6e 2d 70 6f 6c 69 63 69 ss-domai n-polici 00000040 65 73 3d 22 6d 61 73 74 65 72 2d 6f 6e 6c 79 22 es="mast er-only" 00000050 20 2f 3e 3c 61 6c 6c 6f 77 2d 61 63 63 65 73 73 /><allo w-access 00000060 2d 66 72 6f 6d 20 64 6f 6d 61 69 6e 3d 22 2a 22 -from do main="*" 00000070 20 74 6f 2d 70 6f 72 74 73 3d 22 31 32 38 36 39 to-port s="12869 00000080 22 20 2f 3e 3c 2f 63 72 6f 73 73 2d 64 6f 6d 61 " /></cr oss-doma 00000090 69 6e 2d 70 6f 6c 69 63 79 3e 00 in-polic y>.

It's made (I can see with Wireshark and on the server), but no data is sent by Flash. It might be worth knowing that the SWF itself is served from example.com as well.

  • Streaming PDF via invocation of HTTPHandler using $.get into object element

    - by mythicdawn
    What I am trying to do is invoke an HTTPHandler via the $.get method of jQuery which will stream back a PDF and display it in a web page using an object element. My previous method of setting the src attribute of an IFrame to be the result of a handler invocation works, but I would like cross-browser completion notification, so have moved to using $.get(). Sample code: function buttonClick() { $.get("/PDFHandler.ashx", {}, function(data, textStatus, XMLHttpRequest) { var pdfObjectString = "<object data='' type='application/pdf' width='600' height='600'></object>"; var pdfObject = $(pdfObjectString); pdfObject.attr("data", data); $("#container").append(pdfObject); }); As you can see, I am attempting to stick the 'data' variable into an object element. This is not working (no error, PDF just doesn't display), presumably because the data that comes back is binary, yet the attr() method expects a string (I think). My question is thus: how can I invoke an HTTPHandler via $.get and somehow assign the data from the callback to the data attribute of an object?

  • What question(s) does an object's behavior answer?

    - by Corwin
    Reading a book I have found the following statement: (Object) Behaviors answer either of two questions: What does this object do (for me)? or What can I do to this object? In the case of an orange, it doesn’t do a whole lot, but we can do things to it. One behavior is that it can be eaten. In my understanding of object behaviour the statement above is correct regarding the first question and is incorrect in case of the second. However, I often see classes with methods like Orange::eat(), and this makes me uncertain about my design skills. So I would like to ask is it a design mistake to give oranges a behaviour eat? (oranges and eat are used just for example)
