  • Is using Capistrano for user maintenance tasks on university lab feasible?

    - by danielkza
    I've been looking around for tools to replace some legacy scripts for creating and maintaining accounts in a university computer lab ecosystem consisting of things like: LDAP and Kerberos for authentication User home storage and web pages Entries on an SQL database Printing quotas Mailing lists, etc. I'd also like to automate machine and VM membership for Kerberos and Puppet if possiible. I've found Capistrano, and while the basic principle of running tasks on remote hosts through SSH seems to fit, and the DSL in Ruby looks quite nice, I've found most documentation is related to application deployment, not generic tasks. I'm also not aware of any good way to parameterize tasks so I can pass on the user information for creation. Is something about Capistrano I am missing, or is it not the correct tool for this job? Are there any more userful alternatives?

  • Terminal error messages: bash: /dev/cgroup/cpu/user/2823/tasks: No such file or directory

    - by sasaenator
    This is what I get when I start up the terminal: bash: /dev/cgroup/cpu/user/2823/tasks: No such file or directory bash: /dev/cgroup/cpu/user/2823/notify_on_release: No such file or directory bash: /dev/cgroup/cpu/user/2823/tasks: No such file or directory bash: /dev/cgroup/cpu/user/2823/notify_on_release: No such file or directory sasa@sasa:~$*** I reinstalled 10.10 yesterday because of other problems, I didn't have this error message before. I have a separate /home partition, and new installation picked up almost all of the old settings, also those which I don't like, but it looks like that is not a problem or maybe I am wrong? Wouldn't ask if I knew! :) I'll be glad to post more info if someone needs it!

  • How to restrict user to a particular folder in CentOS 6?

    - by Chris Demetriad
    I will need to create users so developers can log in and clone/pull/push changes/repositories from a github like platform. I've managed to add a user (using the root) to this CentOS machine; I now have this line in /etc/passwd: chris:x:32008:32010::/home/chris/public_html:/bin/bash ..and this in /etc/shadow: chris:$1$ruUeLtTu$onAY2hdu1J.UmHajEIlmR.:15385:0:99999:7::: I am able to SSH the server, I have permission to create a folder and I guess that should be enough. But I am able to see other files and folders outside public_html. How can I actually restrict the user to a particular directory so he can't "cd out" of his folder? Update: root@echo [~]# ls -ld /home/moove drwx--x--x 21 moove moove 4096 Mar 22 16:16 /home/moove/ root@echo [~]# ls -ld /home/moove/public_html drwxr-x--- 11 moove nobody 4096 Mar 27 11:29 /home/moove/public_html/ root@echo [~]# ls -ld /home/moove/public_html/dev drwxr-x--- 12 moove nobody 4096 Mar 27 14:47 /home/moove/public_html/dev/ root@echo [~]# ls -ld /home/moove/public_html/dev/arsenal drwxr-xr-x 3 arsenal moove 4096 Mar 27 14:53 /home/moove/public_html/dev/arsenal/

  • Stairway to XML: Level 8 - Deleting Data from an XML Instance

    in order to use the modify() method to delete data from typed and untyped XML instances, you must pass an XML DML expression as an argument to the method. That expression must include the delete keyword, along with an XQuery expression that defines the XML component to be deleted. Robert makes it seem simple, as usual. The best way to version control T-SQLSSMS plug-in SQL Source Control connects SVN, TFS, Git, Hg and all others to SQL Server. Learn more.

  • Enabling super single user mode with SQL Server

    - by simonsabin
    I recently got an email from a fellow MVP about single user mode. It made me think about some features I had just been looking at and so I started playing. The annoyance about single user mode for SQL Server is that its not really single user, but more like single connection mode. So how can you get round it, well there is extension to the -m startup option that allows you to specify an application name, and only connections with that application name can connect. This is very useful if you have...(read more)

  • Performing user authentication in a CodeIgniter controller constructor?

    - by msanford
    In "The Clean Code Talks -- Unit Testing" (http://youtu.be/wEhu57pih5w), Miško Hevery mentions that "as little work as possible should be done in constructors [to make classes more easily testable]'. It got me thinking about the way I have implemented my user authentication mechanism. Having delved into MVC development through CodeIgniter, I designed my first web application to perform user authentication for protected resources in controllers' constructors in cases where every public function in that controller requires the user to be authenticated. For controllers with public methods having mixed authentication requirements, I would naturally move the authentication from the constructor to each method requiring authentication (though I don't currently have a need for this). I made this choice primarily to keep the controller tight, and to ensure that all resources in the controller are always covered. As for code longevity and maintainability: given the application structure, I can't foresee a situation in which one of the affected controllers would need a public method that didn't require user authentication, but I can see this as a potential drawback in general with this implementation (i.e., requiring future refactoring). Is this a good idea?

  • To access parentAM instance from within nestedAM JUnit test class

    - by Abhishek Dwivedi
    In normal model project, the way to access parent AM from within nested AM is simple - ParentAMImpl parentAM =  (ParentAMImpl)this.getRootApplicationModule(); However, the same approach doesn't help in JUnit model project. Use the following approach -  Inside setUp() method --  ParentAM parentAM =  (ParentAM)Configuration.createRootApplicationModule(ROOT_AM, ROOT_AM_CONFIG); Inside tearDown() method -- Configuration.releaseRootApplicationModule(parentAM, true);

  • How To Create a Shortcut That Lets a Standard User Run An Application as Administrator

    - by Chris Hoffman
    Want to allow a standard user account to run an application as administrator without a UAC or password prompt? You can easily create a shortcut that uses the runas command with the /savecred switch, which saves the password. Note that using /savecred could be considered a security hole – a standard user will be able to use the runas /savecred command to run any command as administrator without entering a password. However, it’s still useful for situations where this doesn’t matter much – perhaps you want to allow a child’s standard user account to run a game as Administrator without asking you. We’ve also covered allowing a user to run an application as Administrator with no UAC prompts by creating a scheduled task. HTG Explains: Is ReadyBoost Worth Using?

    - by ambu
    <?php echo `whoami`; ?> So this is returning 'root' and I don't know how to prevent it. I'm using WebHost Manager / CPanel which is supposed to create multiple users/vhosts and have Apache spawn it's process as that user/group. This isn't happening. If I login to WHM and open the PHP and SuExec Configuration section, my settings are: Default PHP Version (.php files) 5 PHP 5 Handler cgi PHP 4 Handler none Apache suEXEC on What's wrong?

  • Making file in user's homedir accessible from web/webserver

    - by evident
    Hi everybody, I have a txt-file one of my user's homedir which is regularly updated there by a script. I now want to be able to access (read) this file from the web. /home/user/folder/file.txt So what I tried now is to log in as root, go into my webservers httpdocs folder /var/www/path/to/domain/httpdocs and there I tried to create a symbolic link with ln -s /home/user/foler/file.txt /var/www/path/to/domain/httpdocs/file.txt But this didn't work... I already tried changing the chmod of the symlink (which changes the ones from the original file of course) and also a chown to the user from webserver, but no matter what I tried I cannot open the file from the web or from a php-script (which is what I want to do) Can anybody help me and tell me what I need to do? What rights do I need to give? Or is there another way of achieving this?

  • T-SQL User-Defined Functions: the good, the bad, and the ugly (part 2)

    - by Hugo Kornelis
    In a previous blog post , I demonstrated just how much you can hurt your performance by encapsulating expressions and computations in a user-defined function (UDF). I focused on scalar functions that didn’t include any data access. In this post, I will complete the discussion on scalar UDFs by covering the effect of data access in a scalar UDF. Note that, like the previous post, this all applies to T-SQL user-defined functions only. SQL Server also supports CLR user-defined functions (written in...(read more)

  • Class instance clustering in object reference graph for multi-entries serialization

    - by Juh_
    My question is on the best way to cluster a graph of class instances (i.e. objects, the graph nodes) linked by object references (the -directed- edges of the graph) around specifically marked objects. To explain better my question, let me explain my motivation: I currently use a moderately complex system to serialize the data used in my projects: "marked" objects have a specific attributes which stores a "saving entry": the path to an associated file on disc (but it could be done for any storage type providing the suitable interface) Those object can then be serialized automatically (eg: obj.save()) The serialization of a marked object 'a' contains implicitly all objects 'b' for which 'a' has a reference to, directly s.t: a.b = b, or indirectly s.t.: a.c.b = b for some object 'c' This is very simple and basically define specific storage entries to specific objects. I have then "container" type objects that: can be serialized similarly (in fact their are or can-be "marked") they don't serialize in their storage entries the "marked" objects (with direct reference): if a and a.b are both marked, a.save() calls b.save() and stores a.b = storage_entry(b) So, if I serialize 'a', it will serialize automatically all objects that can be reached from 'a' through the object reference graph, possibly in multiples entries. That is what I want, and is usually provides the functionalities I need. However, it is very ad-hoc and there are some structural limitations to this approach: the multi-entry saving can only works through direct connections in "container" objects, and there are situations with undefined behavior such as if two "marked" objects 'a'and 'b' both have a reference to an unmarked object 'c'. In this case my system will stores 'c' in both 'a' and 'b' making an implicit copy which not only double the storage size, but also change the object reference graph after re-loading. I am thinking of generalizing the process. Apart for the practical questions on implementation (I am coding in python, and use Pickle to serialize my objects), there is a general question on the way to attach (cluster) unmarked objects to marked ones. So, my questions are: What are the important issues that should be considered? Basically why not just use any graph parsing algorithm with the "attach to last marked node" behavior. Is there any work done on this problem, practical or theoretical, that I should be aware of? Note: I added the tag graph-database because I think the answer might come from that fields, even if the question is not.

  • Saving user details on OnSuspending event for Metro Style Apps

    - by nmarun
    I recently started getting to know about Metro Style Apps on Windows 8. It looks pretty interesting so far and VS2011 definitely helps making it easier to learn and create Metro Style Apps. One of the features available for developers is the ability to save user data so it can be retrieved the next time the app is run after being closed by the user or even launched from back suspended state. Here’s a little history on this whole ‘suspended’ state of a Metro Style app: Once the user say, ‘alt+tab...(read more)
