Why would I need to be root to change the ownership of a file? Example: I'm logged in as dwadmin and I've created a file:
-rw-rw---- 1 dwadmin dgw 0 Jun 17 07:46 testing.txt
I want to change the ownership to another user, but am getting the following error: chown 511 testing.txt chown: changing ownership of `testing.txt': Operation not permitted
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 created a folder structure as root and now need to transfer ownership to an ordinary user.
This question is linked to this one - [URL]
I have a folder /srv/app-share that needs to be visible/writeable to user1
I tried (as root):
root@server [/]# chown -R user1:user1 /srv/
But that did not work.
I have Slackware 12.2 installed on my computer, as well as a Windows Xp. I have a hard drive named '/fat-d', which is formatted to be 'fat' and is normally used under XP. This drive can also be accessed under Slackware, both as root and the normal user.I can not write to the directory '/fat-d' when I am not root, it is normal since 'ls -l' shows that its owner is root and other users have no permission to write. The problem is that, when I tried (as root) to change the owner to the normal user:# chown [normal_user_name] /fat-dI got an error: chown: changing ownership of '/fat-d/':Operation not permittedBut how can the root have no permission to change the owner?

View 2 Replies View RelatedNSA's Guide to the Secure Configuration of Red Hat Enterprise Linux 5 recommands restricting device ownership to root only.
So my question is why should we restrict device ownership to root? And what does device ownership mean anyway in Linux?
i have inherited a mixed bag of sorts: several xp users updating an access mdb with the BE on a lamp stack shared via samba. i have a backup device which gets mounted at: /media/disk... each client record (has) a folder by the companyname on the samba share, and all relative documents are placed there. when the backup script runs, it just copies newer or missing files.
someone has been renaming folders, and not matching the folder name to the related companyname from the mdb. so...the backup script captures and duplicates the data in the renamed folders. some client records also have periods in the name (not required from a data pov), such as 'Company Ltd.' instead of 'Company Ltd'. i can produce a list of company names as the folders should be found easily enough, but get a little stuck with the linux scripting.
i can easily remove and further prevent any unwanted punctuation in the company name on the client record, and create the correct folder name on the samba share with vba, but would also like to:
-for each 'client activity' folder on the backup device
-rename the folder by removing punctuation marks
or
-delete the folder if is a dupe
i tried: ls -al | grep '&' - it properly returns only those lines with an ampersand in the folder name, but returns all folders when i try that with a '.'.
what would be the easiest method to do the renaming? i thought if there was a way to change ownership of the mounted device, then the vba code (easy to write) would be simple.
OK - i just ran chown -R on the external device, changing ownership to (me) instead of root. didn't want to because it took too long, but can now use the MoveFolder method of the filesystemobject from my app to do the renaming instead of some sort of bash script (which i was dreading).
Installed Sidux over LennySidux didn't want to take my usual username, because a folder with that name existed in my home directory.So, I just mounted the home partition and changed the name of my home directory from shay to shay1.Don't know what that did or didn't do permission wise to the files in my old home directory, but I've got a few unowned files floating around my home directory anyway that have been dragged in from old harddrives and such.

I am a Linux Noob of the major kind.I have an MP3 player that is owned by root. I have a SANDISK it in also. I can copy files to the player despite it being owned by root but I can't copy them to the SANDISK which is also owned by root. So what is suppose to be after the colon?How do I determine what that is if it is a directory?How do I change to root to change ownership if that is what I need to do?Is there an application that I can use to change ownership easy and what user do I have to be to do that.
View 5 Replies View RelatedI 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).

Being 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 7 Replies View RelatedI mounted a shared windows folder from my LAN, and I changed the mount point's ownership on Linux using command line `chown me:me windir`. but when I enter the mount point, and to create files, it mentioned me 'Permission denied', but the file is actually created on the windows' folder, and its ownership is root:root.
this problem puzzled my programs going to run on it. cause them will detect a system returned error, and terminate in a abnormal way.
Recently, I decided to wipe my system, put in two 250GB hard drives and rebuild my home file and print server. One of the hard drives is a SATA drive, and the other is not. In any event, they are identified as /dev/sda and /dev/sdb in Gparted. So far so good.
Working on (reading from/writing to) the first hard drive (where the OS is installed) is no problem. However, I have had difficulty trying to get my system to recognize my second hard drive and then allow me (nate) to read and write to said second drive. I followed these directions from the ubuntu community web page during installation:
[URL]
and setup my second hard drive with an ext3 file system. The drive is /dev/sdb. The PARTITION is /dev/sdb1. The MOUNT POINT is /media/TheBase250.
The problem(s) begin at this point. I cannot:
1. Unmount the volume at my will-error says that only root can unmount
2. I am not sure if the command sudo chown -R nate:nate /media/TheBase250 allowed me to take full ownership of said drive. It appears as if nothing changes when I run this command in terminal (even when I am root) Moreover, I cannot give myself permission to read and write files to the drive.
3. However, when I open up nautilus, browse to "TheBase250", right-click in the corresponding "explorer" or "finder" window and look at the properties for the drive, it says that "nate" is the owner (under the permissions tab), but again, I cannot give myself FILE read/write capabilities, nonetheless anyone else. When I try, all that happens is the corresponding box goes back to displaying "---"
4. Interestingly, if I skip nautilus and double-click on the drive from my desktop, again, logged in as nate (only user account created) and then proceed to right-click on the window that opens up, click properties, half the time it says that I cannot make changes to the permissions because I am not "nate." Well, last time I checked, I am nate, and this is, albeit delinquent, my computer.
5. Another piece of information that may be helpful is that if I simply right-click on TheBase250 drive icon on my desktop itself, navigate to the permissions tab, the dialogue box says that "The permissions of "TheBase250" could not be determined"
Some additional information that may be helpful is the output from my fstab file. So, for your benefit, here is the output (the stars are not part of the file, but only to help improve readability):

# /etc/fstab: static file system information.
