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 7 RepliesAccidentally 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 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.

View 10 Replies View Relatedhow to use permissions. I ran into a weird problem in which I am unable to change permissions as root. I have a file I've been testing commands on, and somewhere along the line I think I gave it zero permissions. Now I'd like to restore some permissions, but can't. Here's what I'm looking at:
Code:

after a fresh install of fedora 13 I was expecting a few niggles and here's one, I've googled and read man chmod and chown and there seems to be plenty of conflicting advice, oh yeah the problem, I installed a package called get_iplayer (allows downloading of bbc iplayer content) via yum, only thing is I can only run it as root whereas in f12 I could as a normal user. It's probably the simplest command to change permissions, also I can't find any info on what the different numbers mean (775 777 etc)

View 4 Replies View RelatedI want to have two kind of users in a work machine having ubuntu 10.04,
1) He is the admin, have sudo privilages and install, do all types of work, his username is abhilash
2) A user who is normally a IT administrator, who can just install or remove softwares, but cannot access files of abhilash.
I'm trying to do this and my head is going blank, The problem where i'm stuck is, if IT admin can install softwares, then he can become sudo as sudo su, then he can view my files
So here is a small test i did, first with abhilash.
Code:
Now others and group don't have any permissions! But when IT Administrator becomes root, he can see this file

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 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?

View 2 Replies View RelatedA bit of an oddity that I've recently run into with my storage folder in my system; it's a newly installed drive that I've set to mount at /storage. When I first tried to use it, programs that I used that attempted to write to it tossed Access Denied errors at me in their own way. Checking the permissions (at the Terminal, ls -l / | grep storage) showed that /storage was set to 'rwxrwxr--'--Owner and Group were given full read/write/execute, but Others could only read. However, my logon to my system is a member of group root. Why, then, with the above bits set, would I not be able to write to it? Changing Others permissions to rwx (and presumably rw would have worked out for me since I don't leave anything executable there) allowed me to write to it, but I don't understand why that would have been necessary. So far as I'm aware, the prior drive that was in my system--mounted at the same location--did not need this treatment.

View 1 Replies View RelatedI spent some time programming a useful script which presents the user with a UI of all the samba/W2K8 servers and shares on the domain and they check off the shares and the script maps them. The script can only be run as root because mount doesn't allow users to execute. I was asked to modify the script to allow non-root users similar features. I was able to get this working by running the commands:
Code:
# chmod +s /sbin/mount.cifs
# chmod +s /sbin/umount.cifs
Can someone please explain to me what the 's' option means? The man pages only go as far as to say that it allows for setting suid but I don't really know understand that means or what the implications are by doing this. In a perfect world I would like to create a security group and add users into that group and then grant that group permission to run mount.cifs/umount.cifs rather than making such a drastic global change to a core binary. how I might go about granting members of a group permission to run hand-selected commands like mount.cifs?
Post added at 07:07 PM Previous post was at 04:40 PM Ok, I read up on the /etc/sudoers man page and I think I have a more elegant solution to this problem of user mountable samba shares. I restored my mount.cifs back (chmod -s /sbin/mount.cifs) and I used visudo to grant the access.
Code:
%smbusers ALL=NOPASSWD:NOEXEC:/sbin/mount.cifs,/sbin/umount.cifs
This allows any users in the smbusers group to run mount.cifs/umount.cifs with sudo but without being prompted for a password.
