Ubuntu :: Linux Ignoring Windows NTFS Permissions & Security Settings?

Apr 26, 2010

I have NTFS-protected directories under Windows. However under Linux, even though I'm not logged in as a Super-User, Ubuntu cheerfully mounts all NTFS partitions on this machine and EVERY computer on my home network. This gives my GUESTS complete access to all machines connected to my network: Nautilus -> Windows Network -> Workgroup -> Clicking on any computer Name gives access to windows' administrative shares C$, D$, etc. I've always known that Linux ignores Windows security, but... what is the solution?

Ubuntu Security :: Unable To Set File Permissions (NTFS Volumes)

Oct 3, 2010

In Nautilus I select a directory on local NTFS volume. I'm logged in as root, right-click > Properties > Permissions and I set "Others" to "none". But it doesn't work. I want my friends & visitors to use and enjoy Ubuntu but without access to my NTFS volumes.

Debian :: Using The Same NTFS Partition For Linux And Windows Files

Apr 15, 2015

I have installed Debian as a second OS alongside Win XP, and now I have Win XP on C drive (if viewed from XP), NTFS, my data files (mainly texts and graphics) on D drive (NTSF), and Debian on ext3. Debian sees and opens files on D.

1. If I read-write from-on this D partition from both OSes, is there a chance the data will be corrupted?
2. If I open a Windows-created TXT, GIF, JPG, HTML or other not-proprietary format file from Debian, edit it and save (just SAVE, not SAVE AS) - will this file remain readable from Windows?

Fedora :: Screensaver Ignoring Configured Settings?

Dec 22, 2010

I am using F14 installed from DVD, updated to the latest bugfixes for all packages; I also have the nvidia proprietary drivers installed.I have configured my gnome-screensaver using gnome-screensaver-preferences to have a delay of one hour before it blanks the screen. However, no matter the settings I choose (even testing with only a 1 minute delay) the screensaver always kicks in at the 10 minute mark. This persists no matter the graphics driver I use.The only means by which I can stop the screen from locking while watching videos online is to kill the gnome-screensaver daemon.What information should I provide to assist in determining why this is happening? It's very aggravating. I'll include my current xorg.conf in the event that it may help.

Fedora :: Display 'sleep' Ignoring User's Settings?

Aug 8, 2011

installed Fedora 14 on my desktop a couple of days ago. For the most part, it seems to be fine, but I've got a problem with the 'put display to sleep when inactive for' setting. From the desktop, I've tried going to system/preferences/power management, where I've set the display to go to sleep when inactive for 30 minutes - however, it instead goes to sleep after five minutes. The same applies whether I set it to 10m, 30m, 1hr or never.

Having looked online, someone mentioned gconf-editor as a fix to another issue, so I decided to give that a try as well. Under /apps/gnome-power-manager/timeout, I tried setting sleep_display_ac, sleep_display_battery and sleep_display_ups each to 1800 ("The amount of time in seconds before the display goes to sleep" - 30mins, by my maths) on the off-chance that the OS had incorrectly detected the power source, but the display again went to sleep after five minutes.

If it makes any difference, I'm not using a screensaver, and I think the kernel I have installed is (that's what's given in System Monitor). I've also tried running yum update, again just on the off-chance it'd fix something, but everything is up to date.

Security :: Virus Infect The Windows Xp Ntfs Partition?

Feb 4, 2010

Let's say I have an avi file that contains a virus for ntfs windows xp sp3. I put that file on a linux ext3 partition. Then on a windows xp sp3 nfts computer, I connect to the partition over a network share via smb. I run the file within the share so the file is never physically on the windows xp sp3 computer. In this situation will the virus infect the windows xp ntfs partition?

Ubuntu :: Windows Services And Security Settings For Samba?

Jan 28, 2010

I have been trying to get my Samba 3.x NAS to connect to my Windows XP laptop. I can see the server though I cannot open it and see the shares. I have run various tests on the network and Samba (ping, smbclient) though still cannot find why I can't connect.

I can access the NAS via webmin, so I am thinking I need the security or the services settings on the XP machine. Is there a list somewhere of the Windows XP services and security settings required to share files?

Security :: Setup File Permissions For Multiple Groups/users That Use Windows?

Nov 2, 2010

I have a remote directory shared over NFS called tech with perms set as 0750 and owner set to root:tech. I have 2 groups: tech, and techAdmin. tech can read and execute within tech/. techAdmin can read, write, execute. I have 4 users: user1, user2, user3, user4. user1 and user2 is a member of techAdmin, user3 and user4 are members of tech. simple so far...but wait here's the problem. If user1 creates a file inside tech, user2 cant read or modify it because user1 owns it. Here's a few sites that reference this problem:

Security :: Debian Shows File Permissions Change When Copied To A Windows Partition?

Dec 10, 2010

Some time back using this computer a SucKit rootkit was found. Having dd urandomed the drive, flattened CMOS battery, flashed BIOS, run Knoppix live CD 6.1,using no flat pack battery (laptop), and memtested the RAM, I am still having problems with what I suspect is a javascript file that tries to reload the rootkit from? firmware. I suspect the firmware as everything else should have eradicated it??

Also it or a hacker via a backdoor then corrupts the drivers so devices malfunction. Windows security programs and rootkit detectors don't seem to pick it up. Fresh install of Windows or linux after the above still show this problem, though internet not used. The person who admitted rootkitting this machine is capable of writing java programs or using javascripts to do all this.

When viewed using Ubuntu 8.4 files and dates on a Windows partition appear normal both in file manager and terminal. However booting using Knoppix CD these files are all green, and I cannot change their permissions, even as root. ie: everything is green including text files etc. If I copy them to a linux partition, I can change their permissions and make them nonexecutable and nonwritable. Also on the Windows FAT32 partition the . directory has the date 1 Jan 1970.

If I disable any green files, I can shutdown and reboot cleanly. If I don't I start having problems shutting down [/usr/sbin/init ?] And always these follow a pattern:

Can't remember details as I have now corralled the beast but error messages relating to:


are the start of these.

Ubuntu :: Samba NTFS Write Permissions Only Some Work?

Jan 14, 2010

From a Win 7 client, I can copy/create/delete any files on any share on the Ubuntu Samba server so long that is part of my nix file system which is all ext4.This box also has and NTFS partition on it primarily for storage. I can copy/create/delete anything on this partition form the same Win 7 client with the exception of Quickbook save files.I have scoured the web looking for anything close to this but have yet to find anything that looks similar. Not lloking for a direct answer but if there is anyone else that has issues copying specific types of files to a Samba NTFS partition.

Ubuntu :: Mount An NTFS Drive With Full Permissions?

Jul 22, 2010

The issue I am having is that Virtual Box does not recognize my USB drives. I understand that it is related to the fact that Ubuntu cannot recognize the permissions on the USB NTFS drive. So how do I mount the ntfs drive and gain full permissions?

One post suggested that I have to join my user to the 'vbuser' group in users and groups to fix this in 9.04, but I do not have a "vbuser" group in my list of groups. I am running 10.04.

That is, I have full permissions to make changes in the NTFS drives. But when I switch to KDE, this isn't possible. Options like rename, delete, cut, etc, aren't working, they aren't highlighted.Is there any way I can have full permissions to modify NTFS drives in KDE?

Ubuntu :: Permanently Mount NTFS With Open Permissions?

Jul 25, 2011

I installed a new media drive that I will be using to share with a windows 7 laptop using samba. After days of frustration, I figured out that the sharing is not working because I have to set the permissions for the NTFS drive when it is mounted. Once it is mounted, using chmod, chown or right-clicking in nautilus does not work. As a result, when I try to access the files from my windows laptop, it keeps saying that it can't find the share (due to the permission issue). How do I change the fstab to automatically mount the ntfs drive, and have completely open permissions (read/write/execute by everyone)?


UUID=28ASDFGF4AABFA4 /media/media ntfs-3g defaults,blksize=4096,umask=0000

Software :: Where Does Store Ntfs Permissions

Jul 15, 2011

From what I understand, linux applies mount options to ntfs. Then if I want to change a file's permissions, I suppose it stores them somewhere on system disk or memory? If a lot files need to have permissions changed in different ways, can this use a lot of space? By the way, in general when I write to ntfs, can I expect any kind of problems when windows accesses the same disk?

General :: File / Folder Permissions And Groups On Linux With Apache?

Jun 26, 2010

I'm trying to learn about permissions on linux webserver with apache.Some clues to the system: The server I have to play around with is Fedora based. Apache runs as apache:apache. To allow for e.g. php to write to a file the file needs to be chmod 777. 755 is not sufficiant.What I'm wondering is basically how set up permissions like they should be on e.g. a "shared web host".My main problem is that if I set a permission so that one user cannot access anothers home folder, then apache can't read from the public_html folder either.

To keep the users out I need to set chmod 700. But to let apache to read I need to have at least execute on world,so a 701 basically works, but won't let some users in.So I'm really stuck on what to do. Have been concidering adding the apache user to the frous grours
below to avoid having to add the world execute flag, but is that a bad thing? Should it be the other way around, the users in the groups below should also be in the apache group?I was aiming at having 4 groups:

1. webapp: same as dev_int, but is the only one that can go inside the webapp/live folder to e.g. do an update from the repo.

2. dev_int: can read,write and execute everything in the "web root", including the two below, but nothing outside of the web root

3. dev_ext: can read write and execute in all client folders, but cannot access anything outside of the webapp root

4. clientsBasic ftp accounts. Has a home folder with a public_html, but cannot access any other home folders

Ubuntu :: Assign Permissions On A Partition With Ntfs As The File System?

Apr 6, 2010

can assign permissions on a partition with ntfs as the file system. I am aware of editing fstab and setting some basic permissions. What I am clumsily dictating is can you edit permissions of individual folders for specific users in Linux. I have already tried chmod and such

etc something similar to this

[user@computername user]$ sudo chmod 600 directory

Ubuntu :: Adjust Permissions For Folders And Files On NTFS USB Drive?

May 21, 2010

First off I want to apologize for the fact that the first several paragraphs go into something seemingly unrelated to the subject of this thread. However I want to be sure that those who choose to lend me a hand understand where I'm coming from and why I'm asking that question.I just recently switched from Windows Vista to Ubuntu 10.04. So far I've been loving it mostly. But their is one oddball thing I haven't been able to get working. That is a pair of shared folders located on my NTFS external drive connected via USB2.

The drive was automatically mounted on first boot and has full read/write access for owner (which is my username) right out of the gate. For this reason I assumed I would be good to do this.I've been unable to get it working in Ubuntu. As it stands now I've manually added them to smb.conf, added them to the Samba Server Configuration and finally by right clicking the folder in nautilus and choosing Sharing Options. All with varying resultsAt best it will show the shares under the computer but not allow access. I've also cleared out all of these for those folders to try them individually or in different orders. What I found was that using Sharing Options first gives this error and sets nothing up. But either of the other two will at least show the share albeit with no access.

Quote:'net usershare' returned error 255: net usershare add: cannot convert name "Everyone" to a SID. Invalid parameter.What I've discovered is that if I use just the Sharing Options from Nautilus on any folder located on my ext4 partition or the internal NTFS partition then it will ask if applicable to adjust the permissions and though nothing appears in smb.conf that it works more or less just fine.Having played with "ls -l" I discovered that by default that ownership of the folders on the external NTFS is set to myself and that permissions are 700. On the ext4 partition ownership is set to myself and permissions on folders 711. The folders on the internal NTFS partition has an ownership of "root" and permissions set to 777

From here I tried to use "sudo chmod" via a terminal to manually change permissions for folders on all 3 partitions and I can do so for the ext4 and the internal NTFS owned by root. But no matter what I cannot for the external NTFS.The main thing is I want to know why I can't adjust those permissions on the external. I'm convinced that something to do with the way USB drives work by default must be impacting this but I could not find a single thing anywhere to confirm this much less to offer a solution.The second thing is that I installed and used mountmanager to automatically mount the internal NTFS and according to that softwares options the setup for both it and the external NTFS are the same. But if that is true then why is the external owned by me and the internal by root and the resulting permissions are completely different?

Ubuntu :: Auto Mounting Ntfs Drive With Execute Permissions?

May 10, 2011

Current when my NTFS external drive is auto mounted, I can't run any executables from it.

If I unmount it and then manually do:

sudo ntfs-3g /dev/sdc1 /media/portable

it works fine. Is there a way to make the auto-mount have "full" access so I can run applications from it?

Fedora :: Change Permissions On NTFS Partition?

Jan 24, 2011

I have an NTFS partition that I use to swap file back and forth between Vista and F13. I store school files in there, like documents and text files. When I use Nautilus to access the partition, I am always asked for my root password. This is a little annoying. Is there anyway I can keep this from happening?

I have my Windows partition set up to auto mount with fstab. I can access it fine in the command line and launchers that I created with out the root password. I suppose I could do the same for this partition, but I would like to access it directly with Nautilus if it is possible.

OpenSUSE :: Setting Permissions On NTFS Partition?

May 3, 2010

I've recently installed an OpenSuse 11.2 in what I'd like to be a definitive jump from windows environment.I'm not very confident yet with my linux skills, so at this moment I've yet have both systems installed with a data NTFS partition to store music, movies, documents, and general data that I'd like to use in any of the two systems. The NTFS partition has no writting permissions for anybody except root user, so I can't work anything from my personal user without starting an app like su or login as root. I want to change this by making a group (windowsWriters) where my usual user is included wich I pretend to make the group owner of NTFS partition.

I've created the group and inserted my user into it, but I'm unable to change the owner group nor any permission on NTFS partition or any of it's subdirectories. I've tried to made it through opening dolphin as su (Alt+F2 kdesu dolphin) and through chmod in consolemode logged as root, in both cases the action seems to work correctly and no error is spotted, however when I look again at the partition/folder/file permissions/ownership no changes have been made.

Server :: Samba And NTFS Folder Permissions

Nov 17, 2010

I have a file server setup with samba integrated with swat management. The server isn't a domain controller. The file server is working well with the shares all working correctly except for one problem. I would like the users be able to manage the folder permissions from a windows PC. This can be done from a login as the root user if need be but, the key is that the system be manageable from the windows PC.

I have followed the instructions of multiple how to's but still get and error that access is denied when trying to apply permissions. I am able to search the server for users to add and the names resolve. What are the configurations that I should be looking at where the NT permissions in samba are configured. nt acl support is set to yes and any other acl settings used produce the same result.

Ubuntu :: User Account Settings And Permissions?

May 8, 2011

I'd like to set up my PC so that it has one "master account" for system settings, desktop appearance, etc. And then I'd like other user accounts that read these settings so if I change the settings on the master account, those accounts follow the new settings but cannot change them. But at the same time, these accounts cannot be allowed to read to master account's personal files (documents, music, etc.) Each account would be restricted to its own home directory, as expected.

Is there any way to set something like this up or am I dreaming of the impossible?
