For example
allows fred to switch to the apache user. He has to enter his own password every time he switches. If he shall be allowed to switch without entering his password, write: ---------- Post updated at 21:17 ---------- Previous update was at 21:16 ----------
OK, just saw your edit. If you want to assign rights to a group, use for example:
what if i wish to switch all techx group users to apache group and NOT apache user?
Hi,
I have edited 'sudoers' file to allow 'cads' user shutdown the system without providing a password.
Can someone tell me what's wrong with my file?
It's not working when I 'sudo SHUTDOWN' command:
sudo: SHUTDOWN: command not found
Thanks a lot!

Does anyone know of a utility that can parse through a sudoers file and create an "expansion" dump of all users defined in the User Specification, outputting user, host, and command based on all defined Aliases? (3 Replies)

root@dervish # cat /etc/sudoers
cat: cannot open /etc/sudoers
This is what I get when I try to search for the sudoers files. I want to create a user by name jda and assign him root privileges. How can I do that using sudo command and editing sudoers file.
Please help me. (12 Replies)
i have defined a rule in the sudoers file so a specific user is able to run some commands as sudo with no password.
my question is: is it possible to restrict a user to run commands as sudo only in a certain directory? for example: chown only the files that are located in /var/tmp.
Thank you.

Hi All,
I am new to sudoers file. I am asked to troubleshoot why a particular user (alandhi) is not able to run a script as a different user(scmtg). I have the following line in my sudoers file and the user's name added to the group.

Hi,
I need the details of which ids belong to the sudoers file, and which groups these ids belong to.
Can anyone suggest a way to derive that information into a flat file please?

bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
