## Sudoers allows particular users to run various commands as
## the root user, without needing the root password.
##
## Examples are provided at the bottom of the file for collections
## of related commands, which can then be delegated out to particular
## users or groups.
## 
## This file must be edited with the 'visudo' command.

## Host Aliases
## Groups of machines. You may prefer to use hostnames (perhaps using 
## wildcards for entire domains) or IP addresses instead.
# Host_Alias     FILESERVERS = fs1, fs2
# Host_Alias     MAILSERVERS = smtp, smtp2

## User Aliases
## These aren't often necessary, as you can use regular groups
## (ie, from files, LDAP, NIS, etc) in this file - just use %groupname 
## rather than USERALIAS
# User_Alias ADMINS = jsmith, mikem

## Command Aliases
## These are groups of related commands...

## Networking
# Cmnd_Alias NETWORKING = /usr/sbin/route, /usr/sbin/ifconfig, /usr/bin/ping, /usr/sbin/dhclient, /usr/bin/net, /usr/sbin/iptables, /usr/bin/rfcomm, /usr/bin/wvdial, /usr/sbin/iwconfig, /usr/sbin/mii-tool

## Installation and management of software
# Cmnd_Alias SOFTWARE = /usr/bin/rpm, /usr/bin/up2date, /usr/bin/yum

## Services
# Cmnd_Alias SERVICES = /usr/sbin/service, /usr/sbin/chkconfig

## Updating the locate database
# Cmnd_Alias LOCATE = /usr/bin/updatedb

## Storage
# Cmnd_Alias STORAGE = /usr/sbin/fdisk, /usr/sbin/sfdisk, /usr/sbin/parted, /usr/sbin/partprobe, /usr/bin/mount, /usr/bin/umount

## Delegating permissions
# Cmnd_Alias DELEGATING = /usr/sbin/visudo, /usr/bin/chown, /usr/bin/chmod, /usr/bin/chgrp

## Processes
# Cmnd_Alias PROCESSES = /usr/bin/nice, /usr/bin/kill, /usr/bin/kill, /usr/bin/killall

## Drivers
# Cmnd_Alias DRIVERS = /usr/sbin/modprobe

# Defaults specification

#
# Refuse to run if unable to disable echo on the tty.
#
Defaults   !visiblepw

Defaults    env_reset
Defaults    env_keep =  "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR LS_COLORS"
Defaults    env_keep += "MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE"
Defaults    env_keep += "LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT LC_MESSAGES"
Defaults    env_keep += "LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE"
Defaults    env_keep += "LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY"

## Use a hard-coded PATH instead of the user's to find commands.
## This also helps prevent poorly written scripts from running
## arbitrary commands under sudo.
Defaults secure_path="/usr/sbin:/usr/bin:/usr/local/bin:/usr/local/sbin"

## Next comes the main part: which users can run what software on 
## which machines (the sudoers file can be shared between multiple
## systems).
## Syntax:
##
## 	user	MACHINE=COMMANDS
##
## The COMMANDS section may have other options added to it.
##
## Allow root to run any commands anywhere 
root	ALL=(ALL) 	ALL

## Allows members of the 'sys' group to run networking, software, 
## service management apps and more.
# %sys ALL = NETWORKING, SOFTWARE, SERVICES, STORAGE, DELEGATING, PROCESSES, LOCATE, DRIVERS

## Allows people in group wheel to run all commands
%wheel	ALL=(ALL)	ALL

## Same thing without a password
# %wheel	ALL=(ALL)	NOPASSWD: ALL

## Allows members of the users group to mount and unmount the 
## cdrom as root
# %users  ALL=/usr/sbin/mount /mnt/cdrom, /usr/sbin/umount /mnt/cdrom

## Allows members of the users group to shutdown this system
# %users  localhost=/usr/sbin/shutdown -h now

## Read drop-in files from /etc/sudoers.d (the # here does not mean a comment)
#includedir /etc/sudoers.d
