• Deleting another user's diretories from my own

  - by kwatford

  I am a non-root user, and have made a directory into which other users in my group can write. The directory is setgid, so files and directories within it have the same group. I can delete files placed into this directory, but if a user creates a subdirectory with files in it, I can't seem to delete those. Is there something special I can do (other than, say, bothering the user in question or the sysadmin about it) to get rid of this subdirectory?

• Cannot Delete Shortcut from Desktop because I need Admin Permissions even though I am Admin

  - by DavidB

  Installing the new Malwarebytes 2.0 put a shortcut on my desktop that I want to remove, but dragging it to the recycle bin shows this message: I am an administrator on this computer, so normally clicking "Continue" solves the problem, but it didn't work here. Instead, I got this message. How can I resolve this? I have tried using the built in super administrator account to remove it, but that does not work either.

• How to set default permissions for automounted FAT drives in Ubuntu

  - by piman

  I've got many FAT32 drives that I'd like to mount in Ubuntu such that they have permission mode 700 for directories and 600 for all other files. By default, they have 755 for all files, which is not particularly useful since almost no non-directories should be executable, and it screws up version control repos hosted on the drives. "Back in the day" I would have had the drives listed in /etc/fstab with the umask/dmask I want and there was no such thing as a default. These days, drives automount under their volume names. Which is great, except now I have no idea how to set the default. I have tried changing the /system/storage/default_options/vfat/mount_options gconf key with no apparently effect. It was 077 initially but the mounted drive reflected a default of 022; changing it and re-inserting the drives resulted in the files still having permission bits of 755.

• Create Report in Microsoft Excel - Permissions Issue in Team Foundation Server 2010

  - by sammarcow

  I am trying to use the feature "Create a Report in Microsoft Excel" for Visual Studio TFS 2010. I am being prompted for a username and password in Excel for any given Team Project when right clicking the item "Active Tasks", selecting "Create a Report in Microsoft Excel," found in the following path within the Team Explorer pane, from Visual Studio 2010: 'Collection Name' | 'Project Name' | Work Items | Iteration 1 | Active Tasks I am a Team Project Administrator and Collection Administrator. I checked The SharePoint site: http :// 'serverName'/Reports/Pages/Folder.aspx and have full sitewide and project permissions on this site. I loaded SQL Server Management Studio on the machine running the instance of TFS (and also the SQL backend for TFS) and ensured that I had roles "serveradmin" and "sysadmin". How do I run this report? Specifically, what permissions are required?

• Ownership/permissions of uploaded files

  - by Cudos

  Hello. I want to find out if I am on the right track. My script uploads files to the directory "images". The directory has this setup: owner/group = www-data Permissions = 700 Questions: Is this a good way to secure the directory from a hacker uploading files? Will the hacker be able to upload the files directly to the directory? Note: I have a bunch of other security measures in my upload script + an .htaccess script in the directory that disables script Execution. I just what to know if the permissions on the directory is sensible. I run apache 2.2

• Software for defining rules for folder permissions and monitoring deviations

  - by Kjensen

  Let's say a company has a large number of users, and each user has a home area. On each share used for home area folders, I would like to define some rules saying who is supposed to have which permissions on the folder. Then I would like to audit automatically, that this is actually the case and get some sort of report on deviations. So a rule for \MegaServer\Home01 could be defined something like: Domain Admins - Full Control Backup Agent - Read [Home folder owner] - Full Control I am talking about Windows platform and Windows servers, although I think it would most likely also work for *nix machines that expose Windows shares. Does software like this exist? I could roll my own basic version, but if something already exists, that is usually a better option. I am aware of tools to make displaying permissions easier (AccessEnum, DumpSec), but that is not what I am looking for.

• PHP session files have permissions of 000 - They're unusable

I've tried changing the directory which php.ini uses to /tmp/phpsessions and the same thing occurs. The directories are a+rwx.

• Exchange Full Access issue

  - by Benjamin Jones

  I was just hired as a System Admin for a small company. They use Exchange 2010 for their Mail Server. I've never had a permission issue like this with Exchange because I worked for a larger firm with less responsibility before. Their old system admin is LONG GONE, so I can't ask him what he did. The issue: Right now ANYONE can gain access to a mailbox and view the mail in the mailbox. This is disabled by default you say and you have to grant them full access ? You are right, but the old System Admin I guess didn't know what he was doing. SO right now user A can open up user B mailbox with out being granted permission. So here is what I found out. Every user in EMC Full Access Permission has Exchange Server group granted. Within the Exchange Server Group, Domain User's is a Member Of. Within Domain User's all user's are listed as Members. So my guess is because of this all users can access ANY mailbox? Well GOOD News. The company is small (35 people) and they are not computer savvy, so hopefully no one has figured out they can open anyone's mailbox.(From what I can tell no). Next thing I did was with my domain user in EMC, delete Exchange Servers Group in FUll Access Permissions and grant access to my user. I made sure that my memeber was apart of the Exchange Server Group. Went to our OWA site and now I don't have permission to my own mailbox. Re did everything to the way it was with my user and now I'm stuck. Any help? I would think granting a single user that is in the Exchange Server group, Full Access to that mailbox would enable them to open that mailbox???? I guess I am wrong.

• Windows 2003 Server - File Permissions

  - by nickstan

  I have a Windows 2003 web server with a tree of folders that contains around 100GB of small images. I need to update the permissions on this folder to add a new user with access. I tried to do this by right clicking on the folder and adding the new user but the process never completed. I left it running for around an hour but it started to heavily impact the peformance of the server. Is there any other way to change these folder permissions without affecting server performance? Many Thanks Nick

• Best practice for migrating Shares and Permissions?

  - by TryTryAgain

  We have a Windows 2008 R2 server which is replacing an old Windows Storage Server. The datastore is attached via iSCSI so I do not need to transfer any data. The iSCSI connection is setup on the new machine, and now I'm wondering: How should I transfer the shares and permissions? Do I use PERMCOPY for permissions or is there something better as of Windows 2008 R2 (compared to Windows 2000): PERMCOPY //SourceServer ShareName //DestinationServer ShareName Is exporting/importing registry still a valid option? from: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares Any help/tips would be greatly appreciated.

• What does the red x icon mean next to a user in folder permissions (Windows 7)

  - by Scott Szretter

  In trying to debug various strange issues on a machine, I found something strange - when I go to C:\Users\administrator and get properties, security tab, it lists the users (the local admin account, system, and 'administrator' which is the domain administrator account). It all looks fine in terms of permissions (full control, etc.) compared to other machines. The one difference is there is a small red circle with an X to the left of the user icon/name. Additionally, there are various folders where it says access denied under there - for example, my documents! Even logged in as the local machine administrator account (which is not named administrator), I am unable to change the permissions - it says access denied. Any ideas what this means and how to fix it? I even tried re-joining the machine to the domain.

• Unix / linux permissions setup for shared hosting with Apache

  - by weiyin

  I'm in the process of setting up a server from a clean CentOS 5 install. What is the best permission structure (users, groups, unix permissions) for running a single instance of apache for multiple users? Ideally, it should satisfy these requirements: Each user's websites are stored in a subdirectory of their home directory. Users can edit files and permissions. Apache can read the websites of all users. No user can read the website files of other users. Bonus question: how to add PHP and/or Perl and/or Ruby to Apache without allowing any users to access any other user's files?

• How to set multiple permissions in one class view, depending on http request

  - by andrew13331

  How can I change the permissions depending on if it is a get or a post. Is it possible to do it in one class or would I have to separate it out into two classes? If its a get I want "permission_classes = (permissions.IsAuthenticated)" and if its a post I want "permission_classes = (permissions.IsAdminUser)" class CategoryList(generics.ListCreateAPIView): queryset = QuestionCategory.objects.all() serializer_class = QuestionCategorySerializer permission_classes = (permissions.IsAuthenticated,)

• Read/Write versus Create/Read/Update/Delete permissions difference

  - by archmeta

  From a practical standpoint, is there any real-world difference between Read/Write permissions and Create/Read/Update/Delete permissions? It would seem that if a user had the ability to 'create', he should always have the ability to 'update' or 'delete'? If this is correct, then read/write should always be sufficient, and there is no need to store separate Create/Read/Update/Delete permissions? Are there any real-world use cases in which a user should be given permissions to create but not update, or update but not delete, etc...?

• How to give my user permission to add/edit files on local apache server? [duplicate]

  Possible Duplicate: How to make Apache run as current user I'm setting up my local test server again, and I seem to have forgotten how to successfully set up the LAMP server. I have installed LAMP server via tasksel command and I have configured the /var/www directory according to a guide I've found: After the lamp server installation you will need write permissions to the /var/www directory.

When I give my user the ownership of /var/www recursively as logan:www-data I can create/modify files but cannot view the http://localhost. I get a Forbidden error. I'm assuming that this is because of the Apache's configuration? Which one is healthier or easier considering this is just a local test website, configuring apache to give user logan to view website and chmod /var/www logan:logan so that I can create files etc. without any sudo commands; or is it easier to configure user groups to get www-data user to act like my logan user? (Idk how that's possible, maybe putting www-data user under logan group?) Please shed some light to this subject. All I want is to be able to create/modifiy files under my user, and yet to be able to successfully view http://localhost I appreciate the help!

• Permissions issue: how can Apache access files in my Home directory?

  - by richzilla

  I know file permissions have been covered on here before, but im struggling to get my head around the concept for my scenario. I created the files on an old ubuntu installation. Ive copied the files into my new ubuntu installation and put them in my webroot. When i attempt to run the files (theyre PHP files) i get an error relating to permissions in an attempt to fix this, i assumed that they must still be owned by the previous owner, so i ran chown -R on the directory, with my username as an argument, in order to take ownership of all of the files in the directory. It should be noted that the usernames between new and old ubuntu installations were the same. When i attempt to run the files again, same problem: 500 error due to permissions problems. Can anyone tell me what other steps i should take? The webroot for my apache installation is inside my home folder. If i create new files in my webroot, they also work as expected, its only the old files that are causing the problem.

• Why does Mac OS X ignore my Windows NTFS and Share permissions?

  - by Michael

  Mac OS X Snow Leopard Windows Server 2003 Windows Folder "Videos" Share Permissions on Videos - Everyone NTFS Permissions on Videos - System (Full Control) - Domain Users (Modify) - Domain Admins (Full Control) Mac user Michael is a part of the Domain Users group. He connects to Videos using cifs://server/Videos and authenticates with his username Michael. Michael copies over a file "dance dance baby.avi". User Jon opens the Videos folder but cannot see the dance dance baby.avi file. Checking the dance dance baby.avi file permissions here is what I see: Everyone - Read, Write Domain Admins - Full Control Michael - Read, Write Owner of File - Michael So here's my question, how come when Michael copies a file over from a Mac, the permissions on the file get changed even though Michael has no rights to change permissions? If the same file is copied over from a Windows machine, it just inherits the proper permissions from the parent Video folder. Am I missing something? Are my permissions wrong? Thanks. Michael

• Limit ftp users to only certain directories in Ubuntu

  - by George

  There are several questions around limiting ftp users to certain directories. However, most of them refer to vsftpd, which I don't think I have installed on my system. I'm running Ubuntu 9.04. How can I tell what ftp service I have installed, and then limit certain users to only the /home/ftpuser directory instead of having full access to the file system? I think I can add them to a separate group and give that group access to the proper directories, but then do I have to remove that groups permissions from all other directories? It seems like there should be an easy way like setting the chroot_local_user value in the /etc/vsftpd/vsftpd.conf file, but that doesn't exist on my system.

• Best way to restrict FTP access to a single directory?

  - by John Debs

  I have a VPS running Ubuntu 10.04, and I'd like to give someone SFTP access to a single directory, but prevent them from seeing anything else on the system. What's the best way to pull this off? I considered removing "everyone" permissions from everything on the system, but that seems like a really blunt tool for this problem (and one that'll cause other issues) - I'm hoping there's a better option here. Edit: I appreciate the answers! (And I learned a bunch reading/researching through them). I ended up finding and using this guide from Linode as it spelled all the steps: http://library.linode.com/security/sftp-jails/

• Wordpress Directory Permission to allow uploads, plugin folders, etc

  - by user1015958

  I have a wordpress pre-made site which were developed on my localmachine, and i uploaded it too a vps running on debian6, using nginx, mysql, php. Following this guide: 1) Create an unprivilaged user, this could be say 'karl' or whatever, and make them belong to the www-data group. So that if I were to login as karl and create a web root in say /home/karl/www/ , all the files will be owned by karl:www-data 2) Set up nginx as the user www-data in nginx.conf 3) Set up PHP-FPM to run as www-data 4) Place your files in /home/karl/www/[domain name maybe]/public_html/, upload as 'karl' so you don't have to chown everything again. when i type ls -l inside public_html/ it shows that all the files inside are owned by karl:karl. But the public_html directory is owned by karl:www-data. I chmod 0755 the folder wp-content but i still get the error: ERROR: Path ../wp-content/connection_images does not seem to be writeable. I know i shouldn't set it too 777 due to security reason, how should i set it too proper permission? and what should i set also to allow my users to upload,write posts,edit articles? Sorry for my english by the way.
