  • windows 2008 R2 TS printer security - can't take owership

    - by Ian
    I have a Windows 2008 R2 server with Terminal server role installed. I'm seeing a problem with an ordinary user who is member of local printer operators group on the server. If the user opens a cmd window using ‘run as administrator’ they can run printmanager.msc without needing to enter their password again. In printmanager they can change the ownership of redirected (easy print) printers without problems. If, from the same cmd window, they use subinacl to try and change the onwership of the queue to themselves they get access denied: >subinacl.exe /printer "_#MyPrinter (2 redirected)" /setowner="MyDom\MyUsr" Elapsed Time: 00 00:00:00 Done: 1, Modified 0, Failed 1, Syntax errors 0 Last Done : _#MyPrinter (2 redirected) Last Failed: _#MyPrinter (2 redirected) - OpenPrinter Error : 5 Access denied so, same context, same action but one works and one doesn't. Any ideas for this odd behaviour? I'm using subinacl x86 on an x64 server as I can't find anything more up to date. I've tried with icacls and others but couldn't get them to do anything with printers.

  • Using robocopy and excluding multiple directories

    - by GorrillaMcD
    I'm trying to copy some directories from a server before I restore from backup (my latest backup was corrupt, so I have to use an older one :( ). I'm in the Windows Recovery Environment and have access to the server's file system G:\ and my backup media C:\. But, since I'm more familiar with Linux, I'm having a bit of trouble with the command line in Windows, specifically robocopy. I want to copy multiple directories (maintaining the same directory structure) from G:\ to C:\ while excluding others (namely, the Windows and Program Files folders). I can't figure out the syntax for the /XD option. I was hoping to do something like: robocopy G: C:\backup /CREATE /XD "dir1","dir2", ...

  • Why my browsers display XML files as blank pages?

    - by n1313
    Every time I open an XML file, all I get is blank page instead of tag tree. The file itself is correct and loads okay, I can see it via View Source or in the Firebug. I've tried turning off all my addons and tried running Firefox in safe mode, but the problem was not solved. I'm guessing that I've messed up my configuration somehow and Firefox now tries to render XML files as HTML ones. I've tried googling, but with no success. Help, please? UPD: example file: http://lj.lain.ru/3/1273657698603.sample.xml Also I've noticed that somehow all of the browsers on the machine are now acting the same, so I'm changing the question accordingly

  • Using enums or a set of classes when I know I have a finite set of different options?

    - by devoured elysium
    Let's say I have defined the following class: public abstract class Event { public DateTime Time { get; protected set; } protected Event(DateTime time) { Time = time; } } What would you prefer between this: public class AsleepEvent : Event { public AsleepEvent(DateTime time) : base(time) { } } public class AwakeEvent : Event { public AwakeEvent(DateTime time) : base(time) { } } and this: public enum StateEventType { NowAwake, NowAsleep } public class StateEvent : Event { protected StateEventType stateType; public MealEvent(DateTime time, StateEventType stateType) : base(time) { stateType = stateType; } } and why? I am generally more inclined to the first option, but I can't explain why. Is it totally the same or are any advantages in using one instead of the other? Maybe with the first method its easier to add more "states", altough in this case I am 100% sure I will only want two states: now awake, and now asleep (they signal the moments when one awakes and one falls asleep).

  • Need help translating rate limiting iptables rules to Puppet format

    - by geoffroy
    I use Puppet Iptables module to manage Iptables rules on my machine. I'd like to implement to rate limit failed SSH connections as described here : Hundreds of failed ssh logins iptables -A INPUT -p tcp --dport 22 -m recent --update --seconds 60 --hitcount 5 --name SSH --rsource -j DROP iptables -A INPUT -p tcp --dport 22 -m recent --set --name SSH --rsource -j ACCEPT Is it possible to translate it to Puppet syntax, such as firewall { '015 drop 5 failed attemps to connect to SSH in a minute ': proto => 'tcp', port => 22, action => 'drop', // what are the other paramters ? } Any help welcome. Best regards Geoffroy

  • Tracking the linux config with git: how?

    - by Pierre
    I'd like to track my linux configurations with git. My idea is to have a branch for each server. /etc is not the only one directory to be tracked (I won't git init in '/etc' ) As far as I could see, it is possible to init a git for a distant directory. I tried this: # mkdir -p /git/.git # cd /git # git --work-tree=/ --git-dir=/git/.git init Initialized empty Git repository in /git/.git/ 1) Creating a new branch before everything is not possible # git branch server1 fatal: Not a valid object name: 'HEAD'. 2) adding a file in master/HEAD is not possible # touch README.md # git add README.md fatal: Unable to create '//.git/index.lock': No such file or directory how should I properly setup git to track my system-config ? Thanks. P.

  • Hiding an internal interface in a "friend" assembly

    - by dmo
    I have two assemblies: A and B. A has InternalsVisibleTo set for B. I would like to make calls from A to get information that can only be known by a type defined in B in a way that keeps things internal. I can do this using an internal interface defined in A and implemented explicitly in B. Assembly A internal interface IHasData { Data GetData(); } class ClassA { DoSomething(IHasData); } Assembly B public abstract class ClassB : IHasData { Data IHasData.GetData() { /** do something internal **/ } } The trouble comes when someone references assembly B and derives from ClassB - they get the error: "The type 'AssemblyA.IHasData' is defined in an assembly that is not referenced" even though that type should be invisible to them. If I look at the public type definition I see what I expect - ClassB with no interfaces implemented. Why do I get this error? All of the implementation is in assembly B. I could use IHasData internally in ClassB and that wouldn't require assembly A to be referenced. Can someone help me understand what is going on?

  • If .net sha1 hash expects a byte array, and php sha1() wants a string, can I match the results?

    - by lynn
    I have a set of bytes I want to apply an sha1 hash to. One hash will be in .net, the other in PHP. Then I'll test to see if they match. In .net, you can create a byte array and use sha.ComputeHash(). byte[] data = new byte[DATA_SIZE]; byte[] result; SHA1 sha = new SHA1CryptoServiceProvider(); // This is one implementation of the abstract class SHA1. result = sha.ComputeHash(data); In PHP, you call sha1($string). I can't do anything about the .net side of the code, but how can I get the same hash out of PHP that .net will generate? Please note: I am ONLY able to work on the PHP side of this. The .net stuff is fixed and can't be modified. Thanks!

  • How Does a Login system generally work with OOP?

    - by fakingfantastic
    Sorry if this is a badly formed question, but I'm trying to make my web applications (using PHP) more OO. *EDIT* I'm developing the Framework myself */EDIT* Everything is great so far, I've made a Front Controller system that taps into a MVC system. The FC figures out what page you want, loads the specific page Controller (*EDIT* which extends an abstract Controller Object */EDIT*), which gets anything it needs from Models, and then calls the appropriate View. Very basic. But now, I need to make an admin section (quasi-CMS). How does a login system fit into the grand scheme of things? Do you set controllers as needing a login? If so, how? What If you only want certain views of a controller requiring login? Thanks in advance.

  • Create samba shortcut from command line

    - by neurolysis
    I'm currently wanting to deploy a setup to around 300 Macs. I have most of it scripted, but I'm having trouble creating a working alias to a samba share from the command line. I tried copying it from one Mac to another, but it loses its status as an alias, and instead OSX opens it in TextEdit. From a hexdump, it also looks like it has machine-specific information. So, say I wanted to create an alias to 'smb://server/share' on the desktop from the command line, how would I do that? I have also tried a tell in AppleScript, but it complained about the syntax (specifically, too many slashes, seemingly taking about smb://). Thanks.

  • C#: why Base class is allowed to implement an interface contract without inheriting from it?

    - by etarassov
    I've stumbled upon this "feature" of C# - the base class that implements interface methods does not have to derive from it. Example: public interface IContract { void Func(); } // Note that Base does **not** derive from IContract public abstract class Base { public void Func() { Console.WriteLine("Base.Func"); } } // Note that Derived does *not* provide implementation for IContract public class Derived : Base, IContract { } What happens is that Derived magically picks-up a public method Base.Func and decides that it will implement IContract.Func. What is the reason behind this magic? IMHO: this "quasi-implementation" feature is very-unintuitive and make code-inspection much harder. What do you think?

  • What lessons can you learn from software maintanence?

    - by Vasil Remeniuk
    Hello everyone, In the perfect world, all the software developers would work with the cutting edge technologies, creating systems from the scratch. In the real life, almost all of us have to maintain software from time to time (unlucky ones do it on a regular basis). Personally I first 2 years of my career was fixing bugs in the company that no longer exists (it has been taken up by Oracle). And probably the biggest lesson I've learned that time - despite of the pressure, always try to get as much information about the domain as possible (even if it's irrelevant to fixing a specific bug or adding a feature) - abstract domain knowledge doesn't lose value as fast as knowledge about trendy frameworks or methodologies. What lessons have you learned from maintenance?

  • Life Cycle Navigator?

    - by C.W.Holeman II
    In many environments the file system directory structure and naming conventions attempt to allow one to use a file manager to navigate the life cycle of a document. This overloading of functions makes it difficult for users to handle the complexity. A file browser is a tool that lets the user navigate among files located in a directory structure to find a specific file. Whereas, when given a specific file, a life cycle navigator is a tool that lets the user navigate its life cycle from source to published copy and across versions. Does a Life Cycle Navigator exit? I see a user pointing at an object: Left mouse button displays the document Right mouse button has a Life Cycle Navigator (LCN) The LCN displays a tree for a specific document within a file manger, for example: Published 3.2 Current 3.1 3.0 +2.x +1.x +Archived +All Source Draft 3.2 Current 3.1 3.0 +2.x +1.x +Archived +All +Work Flow +Properties Or from a command line: $ lcn x.pdf --open_source_document | my_favorite_editor $ lcn x.pdf --show_published_version_info $ lcn x.pdf --show_previous_publish_versions_info See also, Life Cycle Navigator.

  • Protected flash video (requires HAL) on Gentoo

    - by Mala
    I am unable to play "protected" flash video, such as Amazon Prime Instant Video. From what I've read and uncovered, this seems to be due to a lack of HAL being installed on my computer. Confirmation that it is required for protected video can be seen towards the beginning of http://helpx.adobe.com/x-productkb/multi/flash-player-11-problems-playing.html However, hal is not in the gentoo portage tree, and in any case has been deprecated and replaced by udev. How can I go about getting Amazon Prime Instant Video to work again? I was considering grabbing the source from http://www.freedesktop.org/wiki/Software/hal but the links there won't load, and trying to install it from old ebuilds or from overlays which claim to still support it (e.g. kde-sunset) result in a compilation error: In file included from addon-generic-backlight.c:38:0: /usr/include/glib-2.0/glib/gmain.h:21:2: error: #error "Only <glib.h> can be included directly." Has anyone else solved this issue?

  • How to set order of appearance for fields when using Html.EditorFor in MVC 2?

    - by Anrie
    I have the following classes in my Model: public abstract class Entity : IEntity { [ScaffoldColumn(false)] public int Id { get; set; } [Required,StringLength(500)] public string Name { get; set; } } and public class Model : SortableEntity { [Required] public ModelType Type { get; set; } [ListRequired] public List<Producer> Producers { get; set; } public List<PrintArea> PrintAreas { get; set; } public List<Color> Colors { get; set; } } To display the "Model" class in the view I simply call Html.EditorFor(model=model), but the "Name" property of the base class is rendered last, which is not the desired behaviour. Is it possible to influenece on the order of displayed fields somehow?

  • Passing arguments to anonymous inner classes

    - by synic
    I'm trying to make an API library for our web services, and I'm wondering if it's possible to do something like this: abstract class UserRequest(val userId: Int) { def success(message: String) def error(error: ApiError) } api.invokeRequest(new UserRequest(121) { override def success(message: String) = { // handle success } override def error(error: ApiError) = { // handle the error } } I'm talking about passing parameters to the anonymous inner class, and also overriding the two methods. I'm extremely new to Scala, and I realize my syntax might be completely wrong. I'm just trying to come up with a good design for this library before I start coding it. I'm willing to take suggestions for this, if I'm doing it the completely wrong way, or if there's a better way. The idea is that the API will take some sort of request object, use it to make a request in a thread via http, and when the response has been made, somehow signal back to the caller if the request was a success or an error. The request/error functions have to be executed on the main thread.

  • PHP script unable to email on OpenBSD Apache

    - by MattC
    I have a webserver running OpenBSD 4.7 and PHP 5.2.12 out of the ports tree. There is a small contact page that is supposed to send an email to a specific address. When I fill in the form using a web browser, it sends the AJAX request to the PHP page which claims it worked successfully but there is no email. The maillog is empty as well. I created a small php script that replicates this functionality and when I run it by hand using the "php -f" command, it sends an email without a problem. I think this has to do with being chrooted but I can't seem to get it to work. Furthermore, I can't seem to get PHP to log. I told it to log to /var/www/logs/php_errors.log and restarted but can't get it to send anything to the file. Does anyone have any tips for debugging these sort of things in OpenBSD?

  • How do I learn algorithms?

    - by Panthe
    Brief History: Just graduated high school, learned a bit of python and C++, have no friends with any helpful computer knowledge at all. Out of anyone i met in my school years I was probably the biggest nerd, but no one really knew. I consider my self to have a vast amount of knowledge on computers and tech then the average person. built/fixed tons of computers, and ability to troubleshoot pretty much any problem I came across. Now that high school is over, Ive really been thinking about my career. Loving, living computers for the past 15 years of my life I decided to take my ability's and try to learn computer programming, why I didn't start earlier I don't know, seems to be big mistake on my part... Doing some research I concluded that Python was the first programming language I should learn, since it was high level and easier to understand then C++ and Java. I also knew that to become good at what I did I needed to know more then just 2 or 3 languages, which didn't seem like a big problem considering once I learned the way Python worked, mainly syntax changed, and the rest would come naturally. I watched a couple of youtube videos, downloaded some book pdf's and snooped around from some tutorials here and there to get the hang of what to do. A two solid weeks had passed of trying to understand the syntax, create small programs that used the basic functions and understanding how it worked, I think i have got the hang of it. It breaks down into what ive been dealing with all this time (although i kinda knew) is that, input,output, loops, functions and other things derived from 0's and 1's storing data and recalling it, ect. (A VERY BASIC IDEA). Ive been able to create small programs, Hangman, file storing, temperature conversion, Caeser Cipher decode/encoding, Fibonacci Sequence and more, which i can create and understand how each work. Being 2 weeks into this, I have learned alot. Nothing at all compared to what i should be lear ning in the years to come if i get a grip on what I'm doing. While doing these programs I wont stop untill I've done doing a practice problem on a book, which embarresing enough will take me a couple hour depending on the complexity of it. I absolutly will not put aside the challenge until its complete, WHICH CAN BE EXTREMELY DRAINING, ive tried most problems without cheating and reached success, which makes me feel extremely proud of my self after completing something after much trial and error. After all this I have met the demon, alogrithm's which seem to be key to effiecent code. I cant seem to rap my head around some of the computer codes people put out there using numbers, and sometimes even basic functions, I have been able to understand them after a while but i know there are alot more complex things to come, considering my self smart, functions that require complex codes, actually hurt my brain. NOTHING EVER IN LIFE HURT MY BRAIN....... not even math classes in highschool, trying to understand some of the stuff people put out there makes me feel like i have a mental disadvantage lol... i still walk forward though, crossing my fingers that the understanding will come with time. Sorry if is this is long i just wish someone takes all these things into consideration when answering my question. even through all these downsides im still pushing through and continuing to try and get good at this, i know reading these tutorials wont make me any good unless i can become creative and make my own, understand other peoples programs, so this leads me to the simple question i could have asked in the beginning..... WHERE IN THE WORLD DO I START ? Ive been trying to find out how to understand some of the open source projects, how i can work with experianced coders to learn from them and help them, but i dont think thats even possible by the way how far people's knowledge is compared to me, i have no freinds who i can learn from, can someone help me and guide me into the right direction.. i have a huge motivation to get good at coding, anything information would be extremely helpful

  • Java cannot find symbol enum

    - by JDelage
    Hi, I'm modeling a chess game on Java, and I'm having some problem. Here's what the code looks like (the relevant parts): Enum class Couleur.java: public enum Couleur {BLANC, NOIR} Piece.java: public abstract class Piece { (...) public Piece(Couleur couleurParam){ this.couleurPiece = couleurParam; } (...) } And finally Tour.java: public class Tour extends Piece { (...) public Tour(Couleur couleurParam){ super(couleurParam); } (...) } All the .java files are in the same folder. Yet at compile I get a "cannot find symbol symbol : variable NOIR location: class Plateau" (Plateau is the class that instantiates Tour.) Can anyone help me figure out what's wrong here? Many thanks, JDelage

  • Puppet exported resource naming

    - by Tim Brigham
    I am working on setting up a collection of Splunk nodes to be deployed by Puppet. One of the steps in this process is importing the trusts to allow these nodes to automatically find each other. I've looked over several options and it appears that exported resources are the only ready way to go for this to work. The files I need to create are under /opt/splunk/etc/auth/distServerKeys//trusted.pem. The source for each of these files should be /opt/splunk/etc/auth/distServerKeys/trusted.pem, one per node. What syntax do I need to make this work? The samples I've looked at all appear to have the same source and destination file name.

  • A c# Generics question involving Controllers and Repositories

    - by UpTheCreek
    I have a base repository class which contains all the common repository methods (as generic): public abstract class BaseRepository<T, IdType> : IBaseRepository<T, IdType> My repositories from this base e.g.: public class UserRepository : BaseRepository<User, int>, IUserRepository I also have a base controller class containing common actions, and inherit from this in controllers. The repository is injected into this by DI. E.g. public class UserController : BaseController<User> { private readonly IUserRepository userRepository; public UserController (IUserRepository userRepository) { this.userRepository= userRepository; } My question is this: The base controller needs to be able to access the repository methods that are defined in the base repository. However I'm passing in via DI a different repository type for each controller (even though they all inherrit from the base repository). How can the base controller somehow access the repository that is passed in (regardless of what type it is), so that it can access the common base methods?

  • Is there a convenient method to pull files from a server in an SSH session?

    - by tel
    I often SSH into a cluster node for work and after processing want to pull several results back to my local machine for analysis. Typically, to do this I use a local shell to scp from the server, but this requires a lot of path manipulation. I'd prefer to use a syntax like interactive FTP and just 'pull' files from the server to my local pwd. Another possible solution might be to have some way to automatically set up my client computer as an ssh alias so that something like scp results home:~/results would work as expected. Is there any obscure SSH trick that'll do this for me? Working from grawity's answer, a complete solution in config files is something like local .ssh/config: Host ex HostName ssh.example.com RemoteForward 10101 localhost:22 ssh.example.com .ssh/config: Host home HostName localhost Port 10101 which lets me do commands exactly like scp results home: transferring the file results to my home machine.
