sudoers file configuration


Hi everybody,

My name is kranti. I am trying to learn about sudoers file.

I wanted to ask the following questions:

1. How to create command aliases for printing,shutdown,reboot and kill commands

2. I have a username called "kranti" on my debian system.

I created a user alias called "SYSADMS" for which I assigned the username "kranti" in the following way:

"User_Alias SYSADMS = kranti"

How to make the changes in such a way that the users with alias SYSADMS will not require any password for sudo.

How to make changes in such a way that SYSADMS will have sudo access but with passwords.


3. I have two groups in my system "tech" and "mang" and a user called "meltechmang001" who belongs to both the groups "tech and mang" . I have to modify or add the sudoers file in such a way that
the user "meltechmang001" is only able to execute reboot and kill commands and nothing else.



May I request you for step by step instructions.

THANKS IN ADVANCE.

did you look at the examples in man sudoers ?

the examples are pretty good at showing how to configure the sudoers file to do pretty much anything you want..

Sudoers is all about the order you do stuff in. This is my sudoers from a while ago.

# sudoers file.

Cmnd_Alias SHELLS = /usr/bin/sh, /usr/bin/csh, /usr/bin/ksh, /usr/bin/bash \
/usr/local/bin/tcsh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/tcsh, \
/usr/bin/zsh
Cmnd_Alias RESTRICT = /usr/sbin/init, /usr/sbin/shutdown, /usr/bin/passwd, /sbin/su, \
/usr/sbin/pkgadd, /usr/sbin/pkgrm, SHELLS

# Defaults specification
