• RemoteApp: Logging in as user x disconnects user y

  - by onik

  I'm having a pretty bizarre problem with a Terminal Services server used for RemoteApp. In our network the server works as it should, but at a client's office if two users log in simultaneously, the first one gets disconnected as the other one connects. The users belong to the same group but have individual users. The similar configuration works fine for all other clients. About the server, it's Windows 2008 R2 x64, no AD, SSL encrypted connections. Event viewer shows no useful information. Any hints where to start debugging? Do you need more info about the setup?

• Performance Difference between HttpContext user and Thread user

  - by atrueresistance

  I am wondering what the difference between HttpContext.Current.User.Identity.Name.ToString.ToLower and Thread.CurrentPrincipal.Identity.Name.ToString.ToLower. Both methods grab the username in my asp.net 3.5 web service. I decided to figure out if there was any difference in performance using a little program. Running from full Stop to Start Debugging in every run. Dim st As DateTime = DateAndTime.Now Try 'user = HttpContext.Current.User.Identity.Name.ToString.ToLower user = Thread.CurrentPrincipal.Identity.Name.ToString.ToLower Dim dif As TimeSpan = Now.Subtract(st) Dim break As String = "nothing" Catch ex As Exception user = "Undefined" End Try I set a breakpoint on break to read the value of dif. The results were the same for both methods. dif.Milliseconds 0 Integer dif.Ticks 0 Long Using a longer duration, loop 5,000 times results in these figures. Thread Method run 1 dif.Milliseconds 125 Integer dif.Ticks 1250000 Long run 2 dif.Milliseconds 0 Integer dif.Ticks 0 Long run 3 dif.Milliseconds 0 Integer dif.Ticks 0 Long HttpContext Method run 1 dif.Milliseconds 15 Integer dif.Ticks 156250 Long run 2 dif.Milliseconds 156 Integer dif.Ticks 1562500 Long run 3 dif.Milliseconds 0 Integer dif.Ticks 0 Long So I guess what is more prefered, or more compliant with webservice standards? If there is some type of a performance advantage, I can't really tell. Which one scales to larger environments easier?

• Why is group write permission ignored in Ubuntu?

  - by NorthPole

  I want my user to have full access to the local Apache root folder, and I also want the Apache user to have full access to the same folder. What I did was create a new group called DevGroup and I added my user and www-data there. Also I changed the permissions to 770 to allow full group access. But now it won't allow me or the Apache user any kind of access to the folder. Here is what I get with ls: drwxrwx--- 12 root DevGroup 4096 Sep 27 17:34 testFolder Which seems perfect but when I try as a user to access the file I get this: var/www$ ls testFolder/ ls: cannot open directory testFolder/: Permission denied Also when I try to access a page in the folder from a browser: [Thu Sep 27 17:47:16 2012] [error] [client 127.0.0.1] PHP Fatal error: Unknown: Failed opening required '/var/www/testFolder/foo.php' (include_path='.:/usr/share/php:/usr/share/pear') in Unknown on line 0 What's the problem and how can I fix it?

• Web App fails when moved to production environment. Which server permissions do I need?

  - by Ashley Ward

  I have developed a small web app. This app allows users to upload images. It also produces text files with the names of those images (the names are stored and retrieved to/from an MySQL Database.) I have developed this app using MAMP. To create the uploaded image files I use the PHP function imagejpeg('my/path/name.jpg') and to delete the files I use the PHP function unlink('folder1/folder2/name.jpg') to write to the text document I am using the function fopen('folder1/folder2/name.txt', 'w') all three of these functions produce errors related to permissions - now the site has been moved to a live hosting environment. Why is this? and what permissions do I need to set the folder's folder1 and folder2 to? I know that permission 777 is generally bad because it opens up your server to the public. However what I have found is that the functions fail to work unless I use 777 on the folders. Can anyone shed any light on my dilemma?

• How can i add Active Directory security groups to a SharePoint site to control permissions, rather than individual user accounts

  - by user574811

  SharePoint does integrate active directory accounts, of course, but how about security groups? Have a few sites where I'm fairly confident access is going through an existing Active Directory (AD) security groups (i.e. only an AD security group has been granted permissions through the 'People and Groups') In another situation, where I created the AD group and granted it permissions to a site, the customers were not able to access immediately. Eventually had to fast-track it and add the individuals to the People and Groups to keep the project going, but hoping not to have to maintain it that way. Any specific requirements of the security group in AD? Universal, Global, or domain local? Is there any time delay between modifying group members in AD and having that take effect in SharePoint?

• What permission(s) does an application pool identity required to manage other application pools?

  - by Mr Shoubs

  I have a web site (used to manage various parts of our software) that needs the permissions required to start/stop other application pools. I've created a user and set the app pool identity to custom, however the web app still can't start/stop the app pools. I get the following Error: System.UnauthorizedAccessException: Filename: redirection.config Error: Cannot read configuration file due to insufficient permissions at Microsoft.Web.Administration.Interop.AppHostWritableAdminManager.GetAdminSection(String bstrSectionName, String bstrSectionPath) at Microsoft.Web.Administration.Configuration.GetSectionInternal(ConfigurationSection section, String sectionPath, String locationPath) at Microsoft.Web.Administration.ServerManager.get_ApplicationPoolsSection() at Microsoft.Web.Administration.ServerManager.get_ApplicationPools() Discussion here suggests setting the application pool to local system or administrator, this does work, but I don't want to do this for security reasons (external support will need access this site). I did give the user higher permissions (as suggested here), starting by making it part of the local administrators group, but initially this didn't work, and giving the user read/write/mod permission on C:\Windows\System32\inetsrv\config also didn't work. I must have done something wrong as local administrator now works, however this still isn't what I want. So can anyone suggest the permissions I need to add to this user, and how can I apply them? An answer my problem (but different question) is here, but to clarify, I think I need to give an individual user "IIS Runtime Operation Permissions", does anyone know how to do this, if indeed this is the permissions I require?

• Why is it necessary to chmod o+r parent directory to fix 403 access forbidden error with Nginx and P

  - by davenolan

  This may be an Nginx wrinkle, or it may be because I don't understand Unix permissions. We're using Hudson CI to deploy our staging instance. So RAILS_ROOT is /var/lib/hudson/jobs/JOBNAME/workspace. Hudson runs as hudson user Nginx runs as www-data user hudson and nginx are both members of the www group root of my nginx conf points to RAILS_ROOT/public as per normal. RAILS_ROOT/config/environment.rb is owned by www-data (so Passenger runs as www-data) RAILS_ROOT and everything in it is owned by the www group and group has r/w/x permissions As it stood, Nginx threw 403 permission denied when requesting any url. error.log contained entries like this: public/index.html" is forbidden (13: Permission denied). These did not fix the or change the error (each with a stop/start of Ngnix): chmod 777 -R RAILS_ROOT chgrp www -R /var/lib/hudson I also tried Nginx as root, and passenger complained that it could not find config/environment (despite the path displayed on the error page being correct). The fix was to ensure everybody has read permissions on each directory in the heirachy. In this case chmod o+r /var/lib/hudson. But if the group has read permissions on the directory, and nginx is a member of the owner group of the directory, why was it necessary to allow everyone read permissions? Is there something have not grokked about permissions? $nginx -V nginx version: nginx/0.7.61 built by gcc 4.4.1 (Ubuntu 4.4.1-4ubuntu8) configure arguments: --prefix=/opt/nginx --add-module=/usr/lib/ruby/gems/1.8/gems/passenger-2.2.5/ext/nginx --with-http_ssl_module --with-pcre=~/src/pcre-8.00/ --with-http_stub_status_module $cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=9.10 DISTRIB_CODENAME=karmic DISTRIB_DESCRIPTION="Ubuntu 9.10"

• How can I access user files on a disk moved from a Windows 7 machine to an XP machine?

  - by Fantius

  I moved the hard drive from one machine (Win 7) to another (XP) and now certain folders tell me "Access denied". I am logged in as an administrator. I had a different account on the other machine. Neither account authenticated to anything besides the local machine. The old machine is apparently dead, so I can't do anything in there like change permissions, etc. How can I access these files? Edit: After changing the ownerships of all the files and folders on the drive, I am getting a different error. And it is troubling me deeply. "xxx refers to a location that is unavailable. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the Internet or your network, and then try again. If it still cannot be located, the information might have been moved to a different location." No change after rebooting. Any ideas? Surely the files are still there, right?

• apache2: Could not open configuration file /etc/apache2/apache2.conf: Permission denied

  - by AntonChanning

  I recently upgraded Ubuntu to the latest LTS edition on my work laptop, which I use as a LAMP development platform. The upgrade was from 12.4 to 14.4. Now I'm having trouble getting apache up and running again. Here is the output from an attempt: antonc@antonc-laptop:/etc/apache2$ sudo service apache2 restart * Restarting web server apache2 * The apache2 configtest failed. Output of config test was: apache2: Could not open configuration file /etc/apache2/apache2.conf: Permission denied Action 'configtest' failed. The Apache error log may have more information. Here is a list of permissions and ownership in /etc/apache, showing that apache2.conf is currently owned by root with permissions 644. I changed this temporarily to 777, but this made no difference, so I changed it back to 644. antonc@antonc-laptop:/etc/apache2$ ls -l total 80 -rw-r--r-- 1 root root 7115 Jan 7 2014 apache2.conf ... What do I need to do to get apache running again? Is the problem really with apache2.conf or some other setting? Should the conf file be owned by a user other than root?

• SQL SERVER – Difference Between GRANT and WITH GRANT

  - by pinaldave

  This was very interesting question recently asked me to during my session at TechMela Nepal. The question is what is the difference between GRANT and WITH GRANT when giving permissions to user. Let us first see syntax for the same. GRANT: USE master; GRANT VIEW ANY DATABASE TO username; GO WITH GRANT: USE master; GRANT VIEW ANY DATABASE TO username WITH GRANT OPTION; GO The difference between both of this option is very simple. In case of only GRANT – username can not grant the same permission to other users. In case, of the option of WITH GRANT – username will be able to give the permission it has received to other users. This is very basic definition of the subject. I would like to request my readers to come up with working script to prove this scenario. If can submit your script to me by email (pinal ‘at’ sqlauthority.com) or in comment field.

• sudo: /usr/lib/sudo/sudoers.so must be owned by uid 0

  - by 7UR7L3

  Whenever I try to do anything at all that requires my password it returns this: u7ur7l3@ubuntu:~$ sudo sudo: /usr/lib/sudo/sudoers.so must be owned by uid 0 sudo: fatal error, unable to load plugins u7ur7l3@ubuntu:~$ So I can't install anything from the Software Center / package manager or run any commands in terminal that require my password. I can log in, but that's pretty much it. I accidentally changed the permissions of some files, then changed some more trying to fix it :/. Now I'm completely lost as to what to do. This is what happened when I tried to get sudo working again using pkexec: u7ur7l3@ubuntu:~$ pkexec chown root /usr/lib/sudo/sudoers.so Error getting authority: Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: GDBus.Error:org.freedesktop.DBus.Error.Spawn.ExecFailed: Failed to execute program /usr/lib/dbus-1.0/dbus-daemon-launch-helper: Success u7ur7l3@ubuntu:~$ sudo ls sudo: /usr/lib/sudo/sudoers.so must be owned by uid 0 sudo: fatal error, unable to load plugins And to change permissions I was using Root Actions as a dolphin service/ plugin thing, so history doesn't show me the permission changes. I just realized that sounds don't work at all anymore. When I go into Phonon my default settings and playback devices aren't even there. Also I don't have the option to shutdown, I can only log out or leave.

• System boots in console + login loop

  - by Imagicien

  I messed up my system while trying to fix permission problems for setting up a LAMP local server. I tried this solution: How to avoid using sudo when working in /var/www? without success. Then I saw this solution: Permissions issue: how can Apache access files in my Home directory? I understood that I had to change the permissions of my root directory (among others), so I executed: sudo chmod 710 / I also changed the user group on / to www-data. I also did these operations on /home. I'm pretty sure one of those commands broke something, because it's the last commands I executed, and after that, my system showed strange/broken behavior: Firefox stopped showing pages Some icons got replaced by an red X icon (meaning "Icon not found" I guess) Applications refused to launch (no reaction) After rebooting: I got a strange graphical message talking about not being able to mount something, asking me if I wanted to wait, and talking about /tmp (I forgot the message since I was in shock) My system now boots in console, and when I login, it flashes unsignificant stuff* before re-asking me to login. My important data is on Ubuntu One. I'd prefer not having to reinstall from scratch. Is there a way to regain access to my system? Thanks a lot for your help. *Looks like a terminal header with the name of the OS and other info. Doesn't seem important.

• Dynamic Query Generation : suggestion for better approaches

  - by Gaurav Parmar

  I am currently designing a functionality in my Web Application where the verified user of the application can execute queries which he wishes to from the predefined set of queries with where clause varying as per user's choice. For example,Table ABC contains the following Template query called SecretReport "Select def as FOO, ghi as BAR from MNO where " SecretReport can have parameters XYZ, ILP. Again XYZ can have values as 1,2 and ILP can have 3,4 so if the user chooses ILP=3, he will get the result of the following query on his screen "Select def as FOO, ghi as BAR from MNO where ILP=3" Again the user is allowed permutations of XYZ / ILP My initial thought is that User will be shown a list of Report names and each report will have parameters and corresponding values. But this approach although technically simple does not appear intuitive. I would like to extend this functionality to a more generic level. Such that the user can choose a table and query based on his requirements. Of course we do not want the end user to take complete control of DB. But only tables and fields that are relevant to him. At present we are defining what is relevant in the code. But I want the Admin to take over this functionality such that he can decide what is relevant and expose the same to the user. On user's side it should be intuitive what is available to him and what queries he can form. Please share your thoughts what is the most user friendly way to provide this feature to the end user.

• Which user does PHP/IIS6 use to read/write files?

  - by Stung

  Hi, I've installed PHP5 (FastCGI) on IIS6 and is just wondering which windows user PHP uses to access the file system? With ASP.NET for example, the ASPNET account is used to access the file system. But how about PHP? I've read some post that suggest it uses the anonymous (i.e. IUSR) account. But isn't it a security breach if I give write access to the IUSR account? Thanks!

• I deleted all files and folders (including hidden) from /home/username/ now in big trouble

  - by jeffery_the_wind

  I am logged into a remote ubuntu server, and I accidentally erased the entire /home/username/ directory for the current user. The only thing left is a hidden directory called .gvfs. I don't need anything of the Documents/Music/etc. Now it is not letting me cd into the /var/www/ directory, which has permissions 666 and it is owned by the current user. I am afraid to disconnect from my ssh session because I don't know if I will be able to get back on. Have I permanently created a problem? Is there a way I can replace the most important files to the /home/username/ directory? Thanks! ** EDIT ** Thanks everyone for the help. I figured the problem with cd into the /var/www/ was actually my permissions in the /var/www/ directory. It was set to 666, changed it to 755 and everything was good again. It doesn't look like anything systematic was ruined by deleting the contents of the user folder.

• How do I start nginx on port 80 at OS X login?

  - by Bryson

  I installed Nginx using homebrew and after completing the installation the following message was displayed: In the interest of allowing you to run `nginx` without `sudo`, the default port is set to localhost:8080. If you want to host pages on your local machine to the public, you should change that to localhost:80, and run `sudo nginx`. You'll need to turn off any other web servers running port 80, of course. You can start nginx automatically on login running as your user with: mkdir -p ~/Library/LaunchAgents cp #{prefix}/org.nginx.nginx.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/org.nginx.nginx.plist Though note that if running as your user, the launch agent will fail if you try to use a port below 1024 (such as http's default of 80.) But I want Nginx, on port 80, running at login and I don't want to have to open terminal and type in sudo nginx to do it. I want it to load from a plist file like Redis and PostgreSQL do. I moved the plist to /Library/LaunchAgents/ from the user folder equivalent and changed its ownership, also tried setting the user directive in the nginx.conf file and still the same error message in Console.app: nginx: [emerg] bind() to 0.0.0.0:80 failed (13: Permission denied) (along with another message telling me that since nginx was being run without super-user privileges, the user directive was being ignored)

• Have only read access to Samba

  - by Tahir Malik

  Hi I've been struggling a lot with Samba on Centos 5.5 lately. I develop in Windows 7 and send files through scp (ant task), but it's to slow and wanted to setup thoroughly samba. After installing and following some guides I've done the following: Disable firewall (iptables) Disable SelLinux (didn't do that at the start, but didn't help either) setup my smbusers file to map my windows user to root (root = "Tahir Malik" -- works) added a current user mitco to the sambapassdb with the command smbpasswd -a mitco , because the windows user had only read access So both the users have read access to my share. Here is my smb.conf snippit: [global] workgroup = MITCO server string = Samba Server Version %v netbios name = centos ; interfaces = lo eth0 192.168.12.2/24 192.168.13.2/24 ; hosts allow = 127. 192.168.12. 192.168.13.

• Umbraco directory permissions | umbPermissions Script

• Permission denied install Joomla CiviCRM

  - by Tim

  Dear All, I am trying to install CiviCRM on a Joomla 1.5.17 web server running Ubuntu 9.10. Uploading the package to the tmp directory in /var/www/[site name]/tmp and installing creates this error: Warning: fopen(/var/www/trbcp/administrator/components/com_civicrm/civicrm/templates/CRM/common/civicrm.settings.php.tpl) [function.fopen]: failed to open stream: Permission denied in /var/www/trbcp/libraries/joomla/filesystem/file.php on line 240 Warning: fopen(/var/www/trbcp/administrator/components/com_civicrm/civicrm/templates/CRM/common/civicrm.settings.php.tpl) [function.fopen]: failed to open stream: Permission denied in /var/www/trbcp/libraries/joomla/filesystem/file.php on line 240 Warning: include_once(/var/www/trbcp/administrator/components/com_civicrm/civicrm.settings.php) [function.include-once]: failed to open stream: Permission denied in /var/www/trbcp/administrator/components/com_civicrm/configure.php on line 115 Warning: include_once() [function.include]: Failed opening '/var/www/trbcp/administrator/components/com_civicrm/civicrm.settings.php' for inclusion (include_path='.') in /var/www/trbcp/administrator/components/com_civicrm/configure.php on line 115 Warning: require_once(DB.php) [function.require-once]: failed to open stream: No such file or directory in /var/www/trbcp/administrator/components/com_civicrm/configure.php on line 140 Fatal error: require_once() [function.require]: Failed opening required 'DB.php' (include_path='.') in /var/www/trbcp/administrator/components/com_civicrm/configure.php on line 140 Initially I got a permissions denied error and thought that Joomla did not have permissions to all its directories but looking at Help-System information all the necessary directories are writable. I then decided to chmod 777 all the directories and try again but it still fails. Looking at the directories afterwards it seems that the new directories being created are not being created 777. By changing them I can get at least one step further before the error appears again. My question is does anyone know how to get round this? I am thinking that the new directories being created will require sudo privileges to have mv and create actions carried out, hence the permission denied errors. Can this be configured in Joomla? Or is there a way to specify that new directories created in /var/www/[site name] take 777 by default? any help greatly appreciated! EDIT: P.S. if anyone could give me a clue as to how the insert code feature works as well that would be great! Might make this post a bit more readable! EDIT2: Well I have had a bash at changing the permissions and ownership. sudo chown -R www-data:www-data /var/www/trbcp I then tried changing the whole /var directory (insecure I know but this is a test and dev server for me to find my feet on) to 777 and still getting permission errors. It seems to be error opening stream? Not a php guy so not sure what that is but could it be that permissions to run php script need to change? any thoughts greatly appreciated.

• ASP.NET MVC Creating a impersonated user.

  Hi, I have a MVC app where I have a User class and the user can also impersonate another user(Admin users only). So I have this code below that authenticates the request and instantiates my version of a User class. It then tries to get the impersonated user from the Session object but Session is not available in this method in the global.asax. Hope this makes sense. How else could I do this? protected void Application_OnAuthenticateRequest(object sender, EventArgs e) { IMylesterService service = ObjectFactory.GetInstance(); if (Context.User != null) { if (Context.User.Identity.IsAuthenticated) { User user = service.GetUser(Context.User.Identity.Name); if (user == null) throw new ApplicationException("Context.user.Identity.name is not a recognized user"); User impersonatedUser = (User)this.Session["ImpersonatedUser"]; if (impersonatedUser == null) user.ImpersonatedUser = user; else user.ImpersonatedUser = impersonatedUser; System.Threading.Thread.CurrentPrincipal = Context.User = user; return; } } User guest = service.GetGuestUser(); guest.ImpersonatedUser = guest; System.Threading.Thread.CurrentPrincipal = Context.User = guest; }

• How can I separate the user interface from the business logic while still maintaining efficiency?

  Let's say that I want to show a form that represents 10 different objects on a combobox. For example, I want the user to pick one hamburguer from 10 different ones that contain tomatoes. Since I want to separate UI and logic, I'd have to pass the form a string representation of the hamburguers in order to display them on the combobox. Otherwise, the UI would have to dig into the objects fields. Then the user would pick a hamburguer from the combobox, and submit it back to the controller. Now the controller would have to find again said hamburguer based on the string representation used by the form (maybe an ID?). Isn't that incredibly inefficient? You already had the objects you wanted to pick one from. If you submited to the form the whole objects, and then returned a specific object, you wouldn't have to refind it later on since the form already returned a reference to that object. Moreover, if I'm wrong and you actually should send the whole object to the form, how can I isolate UI from logic?
