  • Giving SSH access to a user, and security issues.

    - by Kris Sauquillo
    Okay, so I have a VPS and I made an account for a friend so he can host his own domains (using the reseller features in DirectAdmin). He's asking for SSH access, and I know that this is probably a bad idea. Does he have access to my whole server, such as executing commands, accessing my domains that I host on my server? I logged into my SSH using his account details and it let me navigate around all of the root folders/files, and his account is under /home/AccountName/. Is there anyway to restrict his access to his folder only? And the commands he can use?

  • What is the best way to keep database data encrypted with user passwords?

    - by Dan Sosedoff
    Let's say an application has really specific data which belongs to a user, and nobody is supposed to see it except the owner. I use MySQL database with DataMapper ORM mapper. The application is written in Ruby on Sinatra. Application behavior: User signs up for an account. Creates username and password. Logs into his dashboard. Some fields in specific tables must be protected. Basically, I'm looking for auto-encryption for a model properties. Something like this: class Transaction include DataMapper::Resource property :id, Serial property :value, String, :length => 1024, :encrypted => true ... etc ... belongs_to :user end I assume that encryption/decryption on the fly will cause performance problems, but that's ok. At least if that works - I'm fine. Any ideas how to do this?

  • How do I reinforce compression options?

    - by Gooberpatrol66
    Shortly after I got my computer, I enabled NTFS compression on it, selecting the option to compress "all files and subfolders". I recently noticed that several folders on my PC are not compressed anymore, including "Program Files" and "Windows". I suspect this happened when I installed Windows 8.1. The problem is, the only way I can think of to fix this would be to uncheck the tick box under "Properties" for my drive, thus decompressing everything on my drive, and then re-check it with the "all files and subfolders" option. Is there a way to compress all the uncompressed folders without first decompressing the compressed folders?

  • How should I structure a site with content dependent on visitor type (not user)?

    - by Pedr
    I have a website that displays different content depending on two selections made by a visitor: Whether they are a teacher or student, and their learning level (from 4 options). Everything is public and they don't need to authenticate to access the content. Depending on their selection, different content is displayed across the whole site, other than a contact and about page. The tone of the language changes depending on whether the visitor is a student or teacher and the materials available on each page also change depending on the learning level, however in all cases, the structure of the site is identical. Currently I'm using a cookie to store the visitor's selections and render different content appropriately, so I have a single set of URLs which display different content depending on the cookie, with one of the permutations as default. I appreciate this is far from ideal, but what is the better option? Would I be better using a distinguishing segment for each selection, for example: http://example.com/teacher/lv3/resources/activities http://example.com/teacher/lv4/resources/activities http://example.com/student/lv4/resources/activities etc. What is the most sensible way to handle this situation?

  • Firefox: show bookmarks location in search result

    - by merv
    I've been a user of firefox for years. Like most, I collected a large number of bookmarks, and over time it now contins lots of folders and nested folders... When I add a new bookmark, I would like to place in specific folder as other related ones. The thing is when I use the search functionality in the Bookmarks Library, it does not say what folder each item is in. And I end up manually looking through all folders (very tedious!) Any suggestion on how to do more efficiently?

  • What is the best way pre filter user access for sqlalchemy queries?

    - by steve
    I have been looking at the sqlalchemy recipes on their wiki, but don't know which one is best to implement what I am trying to do. Every row on in my tables have an user_id associated with it. Right now, for every query, I queried by the id of the user that's currently logged in, then query by the criteria I am interested in. My concern is that the developers might forget to add this filter to the query (a huge security risk). Therefore, I would like to set a global filter based on the current user's admin rights to filter what the logged in user could see. Appreciate your help. Thanks.

  • Is it possible to autocomplete fields in Sharepoint with user info?

    - by Antoine
    Hi, I'm in charge of a Sharepoint collection, and a user asks this. Is it possible that when a user creates an item, some fields are automatically filled with some info, such as email address and location? Authentication uses Active Directory, so every user is identified when using Sharepoint. The only issue is that, being in a big corporate company, I don't have any access to the server, so it must be feasible through configuration of said site/list or using Sharepoint Designer, but I can't and won't be allowed to deploy anything server side. Any idea?

  • How to delete Document Workspace sub folders with Sharepoint web services?

    - by pclem12
    I'm trying to delete a sub folder in a dws. This is the code I've got: SharepointDocs.DwsSoapClient dws = new SharepointDocs.DwsSoapClient(); dws.DeleteFolderCompleted += dws_DeleteFolderCompleted; dws.DeleteFolderAsync(DWSname+'/'+folderName); In the call back for completion I get no error codes only the message "<Results/>" On the msdn site here, it says this empty message signals a success. However, the folder is still there. Any ideas what could be the problem?

  • What are all things that do/can happen when a user enters in a web page's URL?

    - by Job
    Sorry if this is a naive title. I am trying to break into web development, which is so far a foreign world to me. I have taken a basic intro to OS, intro to Networking as part of my bachelors degree several years ago. I cannot say that we went into things deeply, beyond academic assignments. I would like to understand things much better regarding to this specific task (e.g what goes on in at the OS level, at networking level, what are other computers involved, where do proxy servers and hackers come in). Again, at the very basic level this has been covered, but I would like to review this specific thing better. Are there chapter(s) os a specific book, or specific SHORT reading that you recommend? I have nothing against your list of 20 favorite books, but I want to understand this one thing better in 2-3 weeks of reading after work / on the weekends (realistically 5-10 hrs per week, so I am looking for about 15-20 hrs of reading material, NO MORE). I am not a fast reader :) Thanks.

  • EXCEL - Locking a Cell from User input whilst allowing a Linked combobox?

    - by Christopher Leach
    I have a Protected Worksheet which is a checklist with a series of checkpoints. Each row has Item and Description cells that are locked. Each row has several columns with its contents to be set by a ComboBox and a text input column. Both i have left unlocked. I have Locked the the Item and Description columns and left only the 'Select Unlocked Cells' checked via Sheet Protection. I have one ComboBox on the worksheet that moves around and adjusts its LinkedCell and its Content list using the worksheets SelectionChanged event. When the user selects a cell to bring up the drop down list, the user is able to type into the cell and the Drop Down Box disappears. What is the best way to keep the cell unlocked so it can be selectable(as 'Select Locked Cells" is unchecked) however stop the user from being able to type in the cell and to allow the cells contents to become modifiable only via the ComboBox?

  • Can Visual Studio exclude certain folders when searching for header files?

    - by identitycrisisuk
    I'm having trouble with a library that we are using, which has two copies of header files that are needed - one which we are modifying and building from and another which is automatically created during the build process. I don't fully know why or really want to change this but it can cause a bit of annoyance when on random occasions the go to definition function takes you to the auto created header instead of the one used to build. Usually you can spot it but sometimes you don't and make changes to the auto created one, which are then overwritten or sometimes stay around for a while so that something works on your machine but breaks on other peoples. I don't know if there is any way around this as the auto created folder is in the additional include directories of some of the projects in the solution but I just thought I would ask if there was any good way of reducing the chance of this annoying situation cropping up.

  • how to get powershell to look for files in other folders when moving items?

    - by steeluser
    I have written this script to move files to the destination folder. Looks like I am missing something here because when I run the script, it is only looking for .zqx files in current directory and not all the drives. Please note that the ( dir $paths..) part is returning the list of .zqx files promptly. Paths.txt has drive letters like this C:\ D:\ E:\ $paths = get-content paths.txt mv (dir $paths -r -fi *.zqx | ?{$_.lastwritetime -lt ($sevendaysold)}) -dest e:\xqz Thanks Steeluser

  • How to handle feedback from background threads if the user uses the back button?

    - by Janusz
    I have the following problem: I have an Activity where a user can start a web search showing a new activity to show a progress bar until the results are shown. Now the user can either wait for the results or maybe think about the search parameters, hit the back button and triggering a new search. The search is running in an Async Task and therefor still running if the user hits back. At the moment the thread finishes it calls some methods on the old activity causing the activity to show a dialog. This causes the system to crash because the dialog tries to show itself with a reference to an activity that is not longer present on the screen. How can I achieve a dialog that is only shown if the activity is still active?

  • How to send link/url to confirm user registration and/or password reset/recovery using ASP.Net MVC2?

    - by Mark_DVM_Software
    Hi, I see it all over the place, yet, I could not find one example about this (maybe I don't know the proper wording), I am trying to build using ASP .Net MVC2 (but any example on just ASP .Net would be also helpful) a process that will send a link to the user at the end of the registration process to let him confirm his registration. Also, a similar process to let the user to reset his password, with the typical "forgot password" and send a link/url so that the user can click and type a new password. Can someone help me to either find an example or at least to let me know how to "google" it? Thanks, Mark

  • What is a good solution to link different tables in Hibernate based on some field value?

    - by serg555
    I have article table and several user tables a_user, b_user, ... with exactly the same structure (but different data). I can't change anything in *_user tables except their table name prefix but can change everything else (user tables contain only user information, there is nothing about article or user_type in them). I need to link article to a user (many-to-one), but user table name is defined by user_type field. For example Article table record: ... user_id="5" user_type="a" means that it is linked to a user with id=5 from a_user table (id 5 is not unique in users scope, each user table can have its id 5). Any suggestions how to handle this situation? How can I map this relation in Hibernate (xml mapping, no annotations) so it will automatically pick up correct user for an article during select/update? How should I map user tables (one or multiple classes?)? I would need to run some queries like this: from Article a where a.userType=:type and a.user.name=:name Thanks.

  • How can I get the domain name for a user logged into a Mac via Active Directory

    - by Lawrence Johnston
    In my Cocoa app how can I get the current user's domain when they're logged in via Active Directory? I need to determine two things: 1. If the current user is logged on to an Active Directory domain (only need to handle Active Directory). 2. If 1, the domain of the user. I've found references to Directory Services and the Open Directory Programming Guide but the latter is 10.6 only (I must support 10.5+) and I could not find any examples for the former that gave me an idea of what I needed to do.

  • Running commands though PHP/Perl scripts as a priviledged user on Linux.

    - by jtd
    Background: I am writing a script for a company that will allow users to create FTP accounts through a web interface. In the background, the script must run a bunch of commands: Add the user to the system (useradd) Open and edit various files mail the user via sendmail and a few other things... I'm basically looking for the most secure way of doing this. I've heard of the setuid method, the sudo method, and of course, running httpd as a priviledged user. There will be sanity checks on the data entered of course before any commands are executed (ie. only alphanumeric characters in usernames) What is the method used by the popular scripts out there (webmin for example), as it must be fairly secure?

  • What happens if a user jumps over 10 versions before updating, and every version had a new data mode

    - by dontWatchMyProfile
    Example: User installs app v.1.0, adds data. Then the dev submits 10 updates in 10 weeks. After 11 weeks, the user wants v.11.0 and grabs a copy from the app store. Assuming that the app has got 11 .xcdatamodel versions inside, where ***11.xcdatamodel is the current one, what would happen now since the persistent store of the user is ages old? would the migration happen 10 times, step-by-step through every migration iteration? Or does the actual migration of data (lets assume gigabytes of data) happen exactly once, after Core Data (or the persistent store coordinator) has figured out precisely what to do to go from v.1.0 to v.11.0?
