OpenSUSE Install :: Revert The Changes Or Change The Permissions Again To Root:root Or Make Sudo Work
Aug 10, 2011
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 ?
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?
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 .
When I run sudo as a normal unprivileged user, it asks for my password, not the root password. That's often convenient, but it reduces the amount of information someone would have to have in order to run commands as root. So how can I make sudo ask for the root password instead of the invoking user's password? I know it'd be done with a line in /etc/sudoers, but I can never seem to properly parse the BNF grammar in the man page to figure out exactly what to write.
A few years ago I fellow admin showed me this command:sudo su - to change to rootIs this a 'best practice' method or a hap hazzard approach to system administration?I consulted with a senior admin and he frowned on this access to root.
I tried two times to make an new partition (after the FAT partition on it) on my external hard drive with YaST>Partitioner.Fist I had tried ext3 now I have ext2 on it.Both times the partition (or the corresponding folder in /media) was only writeable to the superuser/root but not to a normal user (readable to the normal user). Root is the owner.The FAT-Partition on the same external drive is owned by the normal user who was logged in as I plugged the USB-cable in.I can unmount both partitions als normal user in natilus.1. Can I start nautilus as root to change the permissions?2. What have I done wrong? Should I use an SuSE Live-CD or an CD with an special partitioning-program instead?ng X20) openSuse 11.1 and Gnome 2.24.1 (mostly, 1 account is using KDE) and Kernel Linux 126.96.36.199-01.1-pae. "/home" is on an separated partition (as part of an extended partition). I have also 2 NTFS partitions for Windows XP (System and Data), and a FAT, a root (/) and a swarp partition.
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)
how 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: jeremy@jeremy-laptop:~/test$ ls -l total 16 -rw-r--r-- 1 jeremy jeremy 235 2011-05-17 13:15 onelink -rwxr-xr-x 1 jeremy jeremy 27 2011-08-02 18:05 threecopy -rwxr-xr-x 1 jeremy jeremy 27 2011-05-09 17:10 three.txt
I was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?
Get Fedora 11 and Apache installed. Open web browser and enter http://localhost and I get a "Fedora Test Page" that shows Apache is working (according to the info on the page). It says to put my web documents in /var/www/html/ ... however, as a user I cannot access it (put anything there) and I can't change the permissions (belongs to root) I'd like to run this as an intranet web server in our small ( <100 users) company.
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 don't know that this post fits here, nor does it fit in "Applications." installing suse doesn't seem to give you the chance to name your computer. Now my computer is called "linux-0qvi" or something strange like that. I want to name my computer. Can I do this now without screwing things up??
Also, during install, there didn't seem to be an opportunity to make a separate root password. My first (and main user) account is now set up with admin rights, so I have to type in my account password every time I do something as root. Can I set a separate dedicated root password without screwing up my system?
I have a Suse 11.0 Server that has been running for a long time and I have not had to touch it, well I need to get into it today and I forgot the password. So I booted it up with the install disc and got into the rescue mode but I am not sure how or which system to mount to change the root password I tried sda and sda1 but it errored out with unknown system type
When I installed OpenSuse 11.2 it mounted I configured to mount all of my windows/NTFS partition. However, one problem is that only root can write to it. I was trying to change it to '777' permission. However, as root I can't change permission. chmod doesn't work and neither does using nautilus (as root) work.I even tried unmounting it and then doing a chmod. That didn't work either.
I'm using XFCE and it doesn't by default lock the screen before hibernating. I see this as a bit of a security risk, and as I can't hibernate while the screen is locked, I'm a bit lost as to how to achieve this.
I've begun editing /etc/acpi/hibernate.sh, here's what I have so far code...
If I run with sudo, the system hibernates, but gnome-screensaver will not fire. I can verify this by trying "sudo gnome-screensaver-command --lock". The screen goes black, but is not locked. The screen locks properly without sudo.
So the only solution I can see is to edit /etc/acpi/hibernate.sh in such a way that gnome-screensaver-command runs under the current user, and pm-hibernate is called as root.
Also, when I click the HIBERNATE button in XFCE, how does it call pm-hibernate under root without prompting me for a password? I normally wouldn't be interested in such things, but as it seems relevant to my problem I'm a little more eager to learn
I've got some troubles when I try to install Vim on Linux while I don't have a root account. The error information is shown below: How can I solve this? Can I install it in another directory other than /usr/local/bin/vim?
I created a chroot jail in /SECURITY/Jail. But when I used the command 'sudo chroot /SECURITY/Jail' to enter the fake root, I got an error message likegroups: cannot find name for group ID 105groups: cannot find name for group ID 119.
I recently got a new external drive and backed all my files up on the new external: movies, music, docs, etc. Now all my files have permission rights to the root only. I was able to change this by open up nautilis from a terminal in root and change the permission on the whole drive to my current user so I can access the files, copy & delete the files. I wanted to change some music file information in Kynamo this morning and was not able to since all the individual files still belong to the root. How can I change this permission issue without having to change each individual file?
A 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.
