I just wanted to set some file permissions right. As root:
Code:
# chown -R kikinovak:users /home/kikinovak/Documents
But all I get is a series of "Operation not permitted" errors. What's going on here? I tried this:
Code:
# find /home/kikinovak/Documents -type d -exec chmod 0755 {} ;
... with the same strange errors.
Accidentally I changed the ownership of all the directories under / to my own instead of root:root. Now I am unable to use sudo and many bad things are happening. Is there a way to revert the changes or change the permissions again to root:root or make sudo work ?
View 3 Replies View RelatedI 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'm very new to Linux, i'm running Ubuntu and i'm trying to install a program. In the instructions it says "Check that you ARE NOT root, never run similar tools as root! just change file permissions". How do i check if i'm root or what am I supposed to do here?

View 4 Replies View RelatedI'm new to Ubuntu Linux but have many years on windows platform. Please can someone help me with how to change the following items.
No.1 I would like to change the HORRIBLE!! YAK!! brown background color behind the word Ubuntu in the start up screen when the machine loads up (before the login). I have located the image file for this which I have found to be: /usr/share/images/xsplash/bg_2560x1600. jpg but the OS says that root is the owner and that I don't have permission to change this. So how can I change this for a color I do like.
No.2 I would also like to change the login dialogue screen style. I know this is possible but again I'm fumbling to see how I can do this. I have tried with the start up manager but every attempt fails, the settings don't take. Once again I suspect permissions are at the bottom of the problem?
No.3 Would like to have a colorful splash screen image on boot up, I've managed to remove the old one (small white 3 ring ubuntu logo on black background) but havent been able to install or replace with a new one. Its been incredibly frustrating, I'm feel sure I'm missing something simple here. Wondering if its permissions yet again?
Anyone who can offer help on any of the above, guidance or advise me would be much appreciated. Please bear in mind that I'm still very much feeling my way with Linux so keep it simple.
How to enable Root login...i cant copy or move something on the HDD...I have administrator rights and password for root but i cant change permissions for the HDD without login on root and root login are not allowed .
View 10 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.
If I use the GUI File Manager I ofter get stuck because I need root permissions to write or delete some file or directory. I realize I can drop down to Terminal and do either a sudo or change the permissions of a particular file, but these are several extra steps. Is there a way I can perform root actions on files using File Manager/Browser? Or is there an alternative file manager program I can explore that is more flexible? I am currently using Debian 6.01a installed from the Live CD, Nautilus 2.30.1.
View 14 Replies View RelatedI want to have two kind of users in a work machine having ubuntu 10.04,

I have a really strange problem. I have a few files in a large directory that I want to make readable by everyone. So I try this:
sudo find readme* -not -perm -o+r -exec chmod +r {} ;
and get this:
sudo: unable to execute /usr/bin/find: Success
I don't know why it says Success, because the permissions were not changed. I verified by typing this:
find readme* -not -perm -o+r -exec ls -l {} ;
and get something like
-rw------- 1 root root 536871076 Nov 22 14:06 readme_20101122200429
-rw------- 1 root root 536871892 Nov 22 14:08 readme_20101122200642
-rw------- 1 root root 293458128 Nov 22 14:10 readme_20101122200859
as a last resort, I tried:
sudo chmod +r *
and got:
sudo: unable to execute /bin/chmod: Success
and again Success really means fail. So, I gave up and logged in as root and tried:
find readme* -not -perm -o+r -exec chmod +r {} ;
This time it worked. Why?

im trying to execute a file. When I try i get the message:

I'm trying to install a script and I need to change the permissions of a file within the script, but I am being denied from doing so.

How can I change the permission without being on Root?
View 3 Replies View RelatedI recently did a fresh install of Ubuntu Maverick, and have found a slight issue with file permissions. Before starting the installation I backed up all my files to an ext3 partition, then during the process I moved all of these files over to an NTFS partition that I am using as a joint storage location for both Ubuntu 10.10 and Windows 7. Upon booting into my fresh Maverick install I found that all the files on my NTFS partition are now owned by root and I am unable to change the permissions using the conventional methods I am used to. I have tried using the GUI method through the properties of the folder, I've also tried using chown and chmod, but all to no avail... No matter how I make the change to the permissions, it will always revert back to root within seconds. who desperately wants full read/write access back to their data?

When I tried to transfer the files from the other HD back to the original HD after a fresh ubuntu install I noticed all my files were restricted to root access.

View 9 Replies View Relatedmy dad has been using Ubuntu for a few weeks now and likes it, however he's having some issues regarding read-only files. He's a doctor and frequently has to download word files to edit, however they always download as a read-only file. While this isn't particularly difficult to do, he finds doing it tiresome and because he isn't the most proficient PC user, may have difficulty with it when I return to school after the summer. I was hoping that there's some way to change the default settings so that all files downloaded are writeable.
Additionally, he has a number CD-RWs which he both retrieves files from and stores them to, however when trying to access these CDs he is told that they are read-only. Right clicking on the CD and trying to change the access permissions doesn't work (says that permissions can't be changed because the disc is read-only).
I've been having a very strange problem, and not sure for how long... but basically, my system wont allow me to change file permissions, even in root mode! I run Ubuntu 10.10 with Gnome and LXDE, kernel 2.6.35-30-generic. It's particularly problematic if I want to run some binaries or programs that you need a shell script to start up (i.e. any new version of Firefox). The usual right-click then going into permissions doesn't work, it just resets whatever changes I make. The weirdest thing is that using the chmod command as root also has no results! The files keep the exact permissions they had before...

View 5 Replies View RelatedI'm working on a remote Ubuntu 9.10 server, which is accessed via VPN. I installed Joomla, but had difficulty uploading new components, which I traced to a file permissions problem. I used FileZilla to FTP onto the site and tried to make the chmod changes I needed, but the commands kept failing. Eventually, I contacted the sys admin and told him I thought that there was an ownership problem with the directories. He checked and told me that I was logging in with exactly the same user name and password that he was using (it's not a live system currently) and that he could make chmod changes without any problems. Because all my attempts were still failing, he eventually did the following:
chown -R administrator:administrator /var/www
/var/www is where all the Joomla files are stored and Administrator is the user name.Now I find that when I run a chmod command in FileZilla, the server reports that it worked (see below):
Status:Connected
Status:Retrieving directory listing...
Command:CWD /etc
[code].....
However, if I go back and check the tmp folder permissions, I find that they are still set to 777.This still looks like an ownership problem to me, but I don't understand why the server seems to think that the chmod changes are working, when they aren't.
Trying to change permissions on a file in /proc/sys/fs/inotify. The command syntax are:
Code:
sudo chmod u+w max_user_watches
and the result is:
Code:
chmod: changing permissions of `max_user_watches': Operation not permitted Also tried to change it when logged in as root, same results. Parent directory permissions are dr-xr-xr-x, and are the same up the chain. Tried to change the directory permissions to u+w, that didn't work either. FWIW, /proc is part of the / partition, and it has ~600MB free space.
I have a program what creates files with a certain user and group as owner. How do I make files created by this program belong to a group I specify myself (I know I can chown and chgrp and chmod but I want the files to have a certain group from the beginning). Also I like to be able to specify permissions for these files.
Btw. it's not my own program so cant change the source code of the program to solve my problem.
