View 14 RepliesI installed Ubuntu from the alternate cd a few days ago to save space and resources on a very old laptop. (install command line, then add what I wanted) But I have struck an interesting problem with file permissions. Various programs like synaptic, leafpad, pcman, Banshee, all require I enter the root password to execute them (or sudo command from terminal). I want to change synaptic from root ownership to sudo and leafpad etc to execute without using the sudo command in terminal. I could get comments on the commands before I execute them in terminal and if I am introducing a security problem, as I am still learning bash. $ sudo chown sudo:sudo synaptic
I would still be asked for my sudo password before being able to open synaptic? As in standard Ubuntu instead of root password.$ sudo chmod 777 leafpad pcman Banshee All users could open these programs from the menu? I have my admin account and a general account which I use for everyday things like surfing the net and listening to music.
I have been VERY lucky and managed to restore from a formatted ext3 /home/ partition. I used testdisk to reset the original partition which had had nothing done to it since formatting(!). However some of the file permissions are a altered and I cannot change them. I have tried "su chmod" and even temporarily enabled the root account itself and tried to alter the ownership/permissions from root 'proper' without it helping.
Here is an example of the output of ls -l
drwxr-xr-x 2 martyn martyn 4096 (date) (time) sponsors
?-----S--T 63231 92820383 44090688 4286824785 (date) (time) order.xls
The first line looks like a normally formed output and indeed is readable. The second line looks corrupted and I don't have a clue how I can reclaim this - or even if it is possible. Should I count my blessings most of my files are intact and leave those be?
I finally replaced my Windows with Linux.. However, I need to run applications and modify files that are on NTFS mounts. I am unable to change ownership, permissions, and groups on these files so I may modify them without having to copy. I have several times attempted to chmod, chgrp, chown, etc.. while logged-in as root user; however it is to no avail. The owner and permissions are still geared towards root. can I change ownership and permissions on NTFS files so I can modify them without having to convert/copy them over to ext4 or different file system?- Matbtw: I am using OpenSuse 11.4 and running Windows apps with VirtualBox (with Vista installation image). I still have Win7 on my computer (non-emulated) and I would like to keep some files on those NTFS partitions so when I occasionally need to boot into Win7 I can modify those files because Windows blows and doesn't support Linux.
View 5 Replies View RelatedI use Linux but have a computer with windows I use for gaming. It died and put the hard drive into another computer and used knoppix to recover my files. I looked at the ownership of the windows files and the owner is knoppix. Now I am concerned that ownership will not work on my new Windows computer (when I finish building it, that is). Since I don't get into Windows much I have no idea what those permissions should be.
If I copy them with owner knoppix can I even access them in Windows to change the ownership to whatever Windows will accept? If I change the ownership before putting them on a CD with knoppix, can I write the CD? I will have to use the hard drive on the new windows box so will not have access to the files later (unless I also copy them to my Linux computer for safekeeping). At least I know the ownership changes to make with Linux.
My system (CentOs5.3) became erratic after i tried to change wholesale the ownership of the /FS. is it possible to change ownership or rwx permissions of files in linux? what is the safeguard available to preserve the consistency of the program files in linux against such an attempt by su?

After burning files to DVD+RW, the owner is changed to root, and all permissions are read only. I want to periodically open these files, update them, and save to the DVD again, but I no longer have permission and cannot change the permissions since I am no longer the owner. I tried sudo commands, but get responses "Read only file system". I have erased and reformatted the DVD and started over but get the same results.
I have Ubuntu 9.04, and have tried Brasero and Nautilus and get the same problem. Am I using the wrong kind of DVD/CD?
I am writing a script that is checking the ownership and permissions of a directory. If the directory in question does not have the correct ownership and permissions, the script will run the appropriate commands to give it the correct settings. The if...then...else syntax. The idea here is the following:
Code:
If <directory> no eq = <ownership root:root> && <permissions 755>
then chown root:root <directory> && chmod 755 <directory>
else exit
fi
What would the correct syntax be for the If line of the loop in question?
I run the servers hosting an intranet, a couple of services and an external websites for my club at university. I'd like to back up all the config files to some version control system to keep track of changes, in case one of my colleagues breaks something. The idea is to keep snapshots and then just roll back the required file in case something happens.
Now to the main issue: How does a version control system handle file permissions and ownership? Does it keep them? Does it set the permissions of the user who committed the last change? These are important questions as we have multiple daemons with different users...

View 7 Replies View RelatedBeing new to Linux, i've just about got used to the Debian setup procedure now, but had a quick question on the default ownership of files and folders. On my default Debian installation, almost all the folders and files are owned by root:root. Is this the correct advised configuration or should the folders and files be owned by a user without root permissions - eg user:user?

View 9 Replies View RelatedI have a Samba share set up on a SUSE server and users connect to the share via Windows XP workstations. On SUSE, if I create a file and grant ownership to "administrator" and give it 770 permissions for example, when someone goes in to modify that file, they become the owner as soon as they save it, and the permissions change to 470 (r--rwx---+) with an access control list. I want to maintain ownership of the file myself and I don't understand why someone changing the file is changing the permissions on it...This is driving me insane because every time someone saves something I have to go in and chmod 770 it before they can save it again.
View 2 Replies View RelatedI have an ntfs partition that I wish to access as a normal user(non-root). For this I did the following. As root I created a folder /windows and did a chmod 777 -R on /windows. Then I added the following line to /etc/fstab
Code:
/dev/sda3 /windows ntfs-3g defaults,nosuid,nodev,umask=000 1 0
Now, the partition is mounted alright but the problem is that when any other user (non-root) creates a files in /windows (say by executing touch newfile) the newly created file has the owner and group set as root. The non-root user can create the file and he can also delete the file, however, he cannot change the permissions of the file and also the owner:group is always set as root:root. How do I get across this problem, i.e. how do I mount a partition, so that a non-root user can also change the permissions and ownerships of the files he creates.

I've created a share using Nautilus on an Ubuntu 11.04 machine and can access it OK from both my Win 7 pc and partner's WinXP machine. We both have Ubuntu accounts and use those to access the share. When an Excel spreadsheet is saved on the WinXP machine the ownership changes and it can then only be opened read-only on the Win7 machine. A further complication could be that the Win7 machine has OpenOffice and the WinXP has MS Office. I'm guessing that XP + Office doesn't really care about or see the permissions, but Win7 + OpenOffice does. Should I be using the share with the same username from both PCs? Is my whole approach misguided?

View 3 Replies View RelatedI export a folder via NFS service.I able to mount this NFS share in another Linux machine.The folder has many files.The ownership of these files aren't belong to single user. There are more than 10 different users' files in the folder.I am trying to migrate all these files to another folder. When I use "cp -a", the new files' ownership are all reset to the logon user.
Both NFS server and client machine has exactly same copy of users/groups as these 2 machines refer to same LDAP directory service. When use "ls -al" to list the NFS share in client, I can see the files ownership is exactly the same as the NFS server.Is that possible to preserve the ownership of files while doing such migration? The "cp -a" fail to deliver the job.

Whenever I try and change ownership of a file it doesn't bring up any errors but when running ls -l it shows that nothing has actually changed.

I've been using Webmin and Putty to set permissions but Putty only allows me the Default Group, it won't allow me to set several groups on the same directory. Webmin seems to allow me to add multiple groups (Webmin --> Others --> File Manager --> Info & ACL tab will provide extended abilities) but when I add multiple groups, they don't seem to take effect? I'm wondering if my setup at the 'Share' level or at the hierarchy of my folder structure (unix based) needs to be set specifically?
