sudo ... davvero

[g3i <g3i@alkool.org>]

Salve a tutti, mi sto accingendo a configurare sudo poichč ho la necessitą di dare det. permessi a due utenti.
Edito /etc/sudoers in questo modo

 sudoers file.
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for details on how to write a sudoers file.
#

# Host alias specification

# User alias specification
 User_Alias     FULLTIMERS = g3i, cate

# Runas alias specification
 Runas_Alias    OP = root, operator


# Cmnd alias specification
        Cmnd_Alias     DUMPS = /usr/bin/mt, /usr/sbin/dump, /usr/sbin/rdump,\
                               /usr/sbin/restore, /usr/sbin/rrestore
        Cmnd_Alias     KILL = /usr/bin/kill
        Cmnd_Alias     PRINTING = /usr/sbin/lpc, /usr/bin/lprm
        Cmnd_Alias     SHUTDOWN = /usr/sbin/shutdown
        Cmnd_Alias     HALT = /usr/sbin/halt, /usr/sbin/fasthalt
        Cmnd_Alias     REBOOT = /usr/sbin/reboot, /usr/sbin/fastboot
        Cmnd_Alias     SHELLS = /usr/bin/sh, /usr/bin/csh, /usr/bin/ksh, \
                                /usr/local/bin/tcsh, /usr/bin/rsh, \
                                /usr/local/bin/zsh
        Cmnd_Alias     SU = /usr/bin/su
# User privilege specification
root    ALL=(ALL) ALL
%g3i    ALL = (ALL) ALL
FULLTIMERS     ALL = NOPASSWD: ALL

g3i e cate sono gli users e g3i č anche il nome del gruppo a cui appartengono.

Esco da visudo e trovo questi errori

What now?

Dico la veritą, sono piuttosto inesperto, qualcuno avrebbe dei consigli da darmi?

Grazie, g3i
