View 2 RepliesHow to allow access to some commands having root privleges to be run by non root user. I am new to unix/linux and I have a major assignment. I have to find ways to run particular commands which can be run only by root from a non root user. I know sudo is one of the way but i need some different approach.
View 8 Replies View RelatedIn order to allow me to shutdown my PC from within fluxbox without being root I ran "visudo" and added the following line:
Code:
psionl0 ALL=(ALL) NOPASSWD: ALL
A check that the line had been accepted showed all ok:
Code:
bash-4.1$ sudo -l
User psionl0 may run the following commands on this host:
(ALL) NOPASSWD: ALL
Yet when I tested it out, I got nowhere:
Code:
bash-4.1$ sudo pkgtool
sudo: pkgtool: command not found
bash-4.1$ sudo shutdown -h now
sudo: shutdown: command not found
bash-4.1$
Have I done something wrong or isn't sudo meant to be used this way?
I need to use Live Media to make changes to a hard disk drive. I tried to sudo to no effect.
Seems like it would be troublesome to authorize root access on Live Media or have sudo allow commands such as pvcreate,lvcreate,vgcreate, especially if the hard disk is not encrypted.

mc (Midnight Commander) in Kubuntu 9.10 (Karmic Koala) has a problem accessing .zip and other archives as a virtual file system. It has to do with a changed format of the output from unzip. Discussions offer a workaround, but that requires system (i.e. root) file access; my work box is locked down.
I have Ubuntu (without the K) 9.10 at home, and I downloaded the source package and made a code change that's a horrible hack (I would not dream of publishing) that would allow me to run my own correctly working copy of mc in a subdirectory of my $HOME. Alas, my "at home" box is configured differently, both in terms of processor(s) and KDE vs. Gnome; a transferred-over mc executable fails immediately with bus error.

This is a system I set up, literally, years ago, with no need to touch it. It was originally set up as a file server, running SAMBA. I am wanting to add CUPS to it, and possibly a web server if it will handle the load. Currently, it is running Debian 4.0 without a GUI.
My next step, if I can't get into the root account, is to install a new OS (and try to salvage the file shares that exist). I just would rather keep the install that I have, but I need to hack/crack or change my root password.
I want to get a of log all the commands executed by the root user with the following details :
incoming ip
username (thru which su was executed)
time and date
all the commands executed as mentioned above.
Also if user has managed to login as root, he should not be able to disable / delete the above info. Can this info be collected at some other physical server ?
I am trying to administer a small group of ubuntu desktops in my classroom. I can use ssh to perform administrative tasks one at a time on each machine, but I want to automate these tasks through a small number of scripts. I am having trouble with running root commands through a script.
On other distros, I think I would simply ssh into the root account, and run the script. But as an ubuntu user, I have only ever used sudo, and folks at ubuntuforums are understandably hesitant to recommend logging in as root. Instead I am seeing suggestions to disable the password requirement for each specific command I want to run, which does not seem like best practice.
Should I enable the root account, give it a password, and ssh to the root account to run the scripts? To be specific, the scripts will do things like install updates, install programs, add or delete users, configure the desktop, etc.
I was using the latest stable release of Debian, dual-booted alongside Windows Vista, with the GNOME desktop, installed via netinst, trying to build and install a library that I knew and trusted, when suddenly I couldn't open the Root Terminal. I clicked the link (in Applications->Accessories (I think, whatever the top one is)->Root Terminal), and in the taskbar I saw an item that said "Starting Root Terminal". A few seconds later, that went away, but the terminal still wasn't open. I tried the regular user terminal, to see the same thing happen. Unsure of what was happening, I tried restarting my computer, since that's always the first step you should take in computer problems.
When I restarted, GNOME wouldn't start. The screen would flash a bit for a few seconds, then a dialog box would appear over a background of static that said "The greeter application is crashing. Attempting another one...".t would then go back to the DOS-style kernel, wait a second, and then the same thing would happen. After several of that, I would get a blue screen which said something to the effect of "It has been detected that the desktop environment has crashed six times in the past 30 seconds.
Waiting two minutes before trying again." When it did that, I tried logging in as root to assess the problem. I gave it the correct password, but it said that it was an incorrect login. After several tries (to ensure I didn't mistype the password), I logged in as myself. Same problem. I tried the su command, with the correct password, and it said it couldn't authorise it.
After a lengthy conversation with a friend of mine who was very good with computers, he basically summarised that he had no clue, but that his best guess would be a virus. Upon running the Linux installer, I found the Repair option. Not being particularly familiar with Linux, I used it simply to backup my important files onto a flash drive. I then tried running the Install option, in an attempt to simply write over my existing Linux and make it new again. The installer, however, consistently froze up when trying to start the partitioner, on the "Checking disks..." stage. I figured it was a problem with my partition. In my naivete, I simply used the Windows tools to clear that partition... It destroyed GRUB too, so I couldn't run any OS. I figured my computer was pretty well screwed, and at that point just decided to bring it into the shop and have them completely wipe it.
my computer was backed up onto an external hard driven I brought it back, I reinstalled Windows. Upon restart, it said that it was still looking for GRUB, which made no sense to me. After messing around with it a bit, I decided to just reinstall Linux too. To my lack of surprise, that fixed the problem. Both OS' now ran just fine. The first thing I did on Debian was to install the Clam Anti-Virus, which I understood to be one of the best Linux anti-viruses. However, within about 10 hours, got the same problem as originally. I wasn't doing any of the same things, and between the lack of consistency in activities and the fact that I had an anti-virus running,figured it wasn't a virus. Not knowing what to do, I just left it and have been using Windows since.
This is the hard way to learn when you MUST use visudo. That's right. I did something stupid like:Quote:$ sudo vi /etc/sudoersand now have:Quote:
$ sudo

when you attache a pen drive with windows you can drag from the pen drive to the desk top, and visa versa. with Linux logged in as normal user I can drag files from pen drive to Desktop but not the other way around. my pen drive is TITANIUM and at /dev/sdb1 mounted at /media/TITANIUM so I have to use
cp /home/user/Desktop/file /media/TITANIUM as root
If I log in as root I can drag files from pen drive to desktop and also from Desktop to pen drive. is there an easy way to give permissions for normal user. I had a look a groups and it has scanner, printer etc listed ,can I amend groups somehow to enable same permissions for pen drive access as root?
I am a user of a cluster. I don't want root to see/copy files from my user account(obviously). Is that possible to limit the access of root to users account?
View 14 Replies View RelatedI use two separate systems both running Debian 8. On one (my main) I can't do some commands including ping, shutdown and reboot without running them as root user, however on my other system I can ping and reboot as a non-privileged user. The permissions on both systems are the same for /bin/ping and /sbin/systemctl (reboot). I thought at first it was something to do with what groups my main was in, but that doesn't seem to be the gase.
I know I can fix it by setting setuid for both, but my question is why is it different on both machines? Is there a global setting controlling this in /etc or perhaps an icmp setting?
