| ## 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... |
| |

| # plugin, if any. Starting with 1.8.15, only groups of the form |
| # %:group are resolved via the group plugin by default. |

| ## 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=/sbin/mount /mnt/cdrom, /sbin/umount /mnt/cdrom |
| |
| ## Allows members of the users group to shutdown this system |
| # %users localhost=/sbin/shutdown -h now |
| |
| ## Read drop-in files from /etc/sudoers.d (the # here does not mean a comment) |
| #includedir /etc/sudoers.d |
