Sudo configuration syntax
Lines in sudo configuration use following format:
<username> or %<group> <machine> = [(<user>)] [NOPASSWD] :<command1> [, <command2> ...]
Note that group is indicated using %sign.
For example:
saurabh barjatiya = (root) NOPASSWD: /usr/sbin/wireshark, /usr/sbin/tcpdump
will allow user 'saurabh' to run '/usr/sbin/wireshark' and '/usr/sbin/tcpdump' commands on machine 'barjatiya' without supplying password as root user.
Please note that by default sudo requires tty. Hence running sudo commands from services such as MySQL, apache, nagios, etc. which do not have tty may not work. To change this default behavior comment 'Defaults Requiretty' in /etc/sudoers using visudo.
