is there a way to edit which commands require a sudo? or some programs, like the CPU frequency monitor on panel, requires a password to change. where would i start if i want to change this?
View 2 RepliesI thought ubuntu was the only distro that requires the 'sudo' command. I could have sworn I just read that OpenSUSE does, too. So who all *requres* it?
View 3 Replies View RelatedIt appears that Lucid has done away with the gksu prompt that used to greet you when you try to mount a partition. Is there any known way of restoring this? I have a number of partitions which I would rather have protected by a password (even though I know that booting a live cd will give anyone access to any mountable partition, no questions asked). I've had a quick look in gconf and found nothing that looks like it would control this behaviour, but it's quite likely that I overlooked something.

I was following a guide to stop Ubuntu from always asking the root password. And apparently i messed something up in vsudo edit or something like that i was in... So now when i put in a sudo command i get this...

so i cant even get back to undo what i edited.
I am unable to use sudo and su - commands. check my output below:

does anyone know how to set restrictions on the commands a user can run as sudo? i want to make it so they can only halt the system.

I had a problem - the Wi-fi card in my laptop was not working. All the forums were useless. They wanted me to READ about wireless networking !
Finally a good friend solved the problem in a simple way : it appears Ubuntu has not installed the drivers for my Broadcom wireless card since it was not open source. I had to download it myself. Here is how : Go to System menu on the top bar. Choose administration/ hardware devices. Tell it to activate the device. It will download the drivers through the cable attached to DSL modem and install.
Then clicked the network icon, selected edit connections, and entered my wireless network name and password. This solved all problems.
Why doesn't Linux give me a warning that the driver for something is not yet installed ? When I was struggling with the network setup wizard for the whole day, there was no clue about the missing driver.
I have been using docky lately (its a great app!) and I am just wondering if there is some way I can make it show all windows in an expose-like format if multiple windows are open, just like the Unity launcher.
Is there any way I can achieve this without switching to Unity?
I need to have regular user run this command sync; echo 3 > /proc/sys/vm/drop_caches
but it requires root privileges that I cannot give.
So I figured they could run the command as "sudo". I looked in /etc/sudoers and wasn't sure what I needed to edit for the users to run the following command
sync; echo 3 > /proc/sys/vm/drop_caches
Having a problem with sudo. I'm down as a user who can run all commands as root provided I enter my password. The relevant line from my /etc/sudoers file :
Code:
user1 ALL=(ALL) ALL
There are several commands that I run quite frequently such as mount and fdisk but would like to avoid having to enter a password each time I use them. What would be the appropriate change to the sudoers file ?
UPDATE: I neglected to scroll down to the bottom of the /etc/sudoers file where there was the line :
Code:
%admin ALL=(ALL) ALL
and since user1 was a member of the admin group any predeeding lines were being overidden by this. Commenting out this line and adding
Code:
user1 ALL= NOPASSWD: /bin/mount, /sbin/fdisk
trying to devise a new sudoers configuration while building a new SOE and would like to force everyone (including system administrators) to use rootsh in favour of doing things like sudo -s, sudo bash, sudo tcsh and so forth. Effectively, use sudo to use any shell other than rootsh. Is there a way to allow users to run anything they want except shells. I realise this is a default permit which inherently is defective, but I'm not convinced that going through the 1559 executable commands of my (as yet incomplete) built system to decided on the likely 1000+ commands I would want to be genuinely allowed. As I said this is for system administrators first, and I'd like to forcibly instil the habit of sudo <command> or using rootsh to get an audited shell. But I know people are already not doing enough sudo <command> as it stands, rather they switch to bash.
View 7 Replies View RelatedI am here with a troublesome question about my new Ubuntu set up. Well as I've found out that you have to use the Sudo command to edit anything out side the home directory. Well I am using L.A.M.P. Server on my computer so I can host a small forums. Well for example like lets say I install Word press Blog onto my lamp server and I want to install a theme well when i go to install a theme i can not because WPB can't install the theme because of the security stuff on Ubuntu!
Well I want to know if there is some kind of command or program i can use that will get rid of all the security stuff were i can edit stuff nice and easy. Like something that can give me FULL control over the OS so no more commands because I am going to be running a Vbulliten forums which needs themes and plug ins, well i want be able to install them because this OS will not let me!
edit the sudo config file to allow my account to use some commands as a root.so can someone advise me how should i do it.
View 3 Replies View RelatedCustomer asked me to create a menu for linux he also asked me to do this: Open like a command like where a user can execute commands...so for this the users have sudo enabled. The code below works OK. But it has an issue when a command is executed but the command does not need sudo
Like for instance
Code:
cd /
sudo: cd: command not found
How can I allow a user to execute all commands when a command does not need sudo
Code:
echo -e "Press Control+C to finish"
#echo -e " "
while true;
do
read whichcmd?"Insert Command: "
sudo $whichcmd

In 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?
recently I did some changes to my bashrc file the changes are as follows

Suppose when I issue history command it is showing 100 entries with number attached to each command executed.
how to edit the history to remove few commands executed by me so as to protect the system from other users.
I have a few small still images of around 300 bytes each that I created under Windows many years ago, I'd like to:
1) change the colour of some pixels on each and
2) make them the exact same size but I do not want to learn Gimp to do this since I have no other use for it.
Could someone show me the sequences of commands in Gimp GUI that will do the job?
I am learning linux commands. I just wanted to see what happens when I type
Code:
The screen became blank. Keyboard was not responding. I couldn't do a proper shutdown. I switched off computer by pulling out the plug. When I restarted, I heard a series of beeps (approximately 10 beeps). Then I was dropped to the grub prompt. The problem now is I can not type anything into the grub prompt, because the character 'c' is continously printed across the screen like this:
Code:
I couldn't stop the character 'c' from printing (I tried pressing Esc, Ctrl+C)
The solution is easy. I can reinstall grub from a livecd. Or even reinstalling the entire operating system wouldn't take more than 30 minutes. But I want to know:
1) What exactly happened to grub? What stage does this error belong to (1, 1.5 or 2)? What is the error number?
2) How can running "sudo kill -9 -1" affect grub?
I did some digging on the sudo command and I do know the config file is /etc/sudoers Read the manual for sudoers and found out that I must use visudo to edit the file I read some of the examples at the bottom of the file and tried entering my own account in following the example. one of the commands I was trying to allow my account to perform without root login is the mount command So I tried adding this in (kreid8 /bin/mount ALL) I then saved & exited the file and logged out of root and tried sudo mount -t vfat /dev/sdc1 /media. I got an error saying I had to be root in order to do that But when I use the visudo -l option it shows that I have that privellege. Did I edit the file incorrectly?
View 6 Replies View RelatedI have written a script to run commands on remote servers, it is working fine. But when I am running "sudo commands" on the remote servers, it asks for me password after prompting for ssh password.

I was looking at some Vim plugins, and I installed one called Abolish. The page from where I got it [URL] only says:
install details
Extract in ~/.vim or ~vimfiles
So I extracted it in ~/.vim. Now, the issue is that, if I edit a file as root, I am able to use the commands; however, when I edit a file as a normal user, these commands won't work. So... could this be a permissions issue? Or should I copy the plugin in some other directory, maybe?
since a recent upgrade to Mandriva 2010.1 I am not able to 'sudo' as administrator or when I use the 'root' password. I am the only user on this machine (Dell Inspiron 530S multi-booted with Window's Vista Home Premium, Ubuntu 10.4, and Mandriva 2010.1). I can get into the 'Manage Users' section of the control center by authenticating as 'root' but I can't access 'sudoers file' from command line.

What is the difference between the commands "su" and "sudo -i"?
When I do sudo -i, it asks me the password and after typing my password, I login.
But when I do "su",it asks for my password, and I type the same password as for the sudo -i, but the terminal shows su: Authentication failure Why is it so? Does these commands have different passwords? If so I've forget password for "su". Now what to do?
explain the difference between these two commands. I'm currently reading about changing your mac address and both of these commands show up a lot. They sound like the same thing to me. Is one better than the other, or do you need to use both to change your mac address?
