root@OpenWrt:/usr/share/collectd# cat /etc/sudoers
## sudoers file.
##
## This file MUST be edited with the 'visudo' command as root.
## Failure to use 'visudo' may result in syntax or file permission errors
## that prevent sudo from running.
##
## See the sudoers man page for the details on how to write a sudoers file.
##
##
## Host alias specification
##
## Groups of machines. These may include host names (optionally with wildcards),
## IP addresses, network numbers or netgroups.
# Host_Alias WEBSERVERS = www1, www2, www3
##
## User alias specification
##
## Groups of users. These may consist of user names, uids, Unix groups,
## or netgroups.
# User_Alias ADMINS = millert, dowdy, mikef
##
## Cmnd alias specification
##
## Groups of commands. Often used to group related commands together.
# Cmnd_Alias PROCESSES = /usr/bin/nice, /bin/kill, /usr/bin/renice, \
# /usr/bin/pkill, /usr/bin/top
# Cmnd_Alias REBOOT = /sbin/halt, /sbin/reboot, /sbin/poweroff
##
## Defaults specification
##
## You may wish to keep some of the following environment variables
## when running commands via sudo.
##
## Locale settings
# Defaults env_keep += "LANG LANGUAGE LINGUAS LC_* _XKB_CHARSET"
##
## Run X applications through sudo; HOME is used to find the
## .Xauthority file. Note that other programs use HOME to find
## configuration files and this may lead to privilege escalation!
# Defaults env_keep += "HOME"
##
## X11 resource path settings
# Defaults env_keep += "XAPPLRESDIR XFILESEARCHPATH XUSERFILESEARCHPATH"
##
## Desktop path settings
# Defaults env_keep += "QTDIR KDEDIR"
##
## Allow sudo-run commands to inherit the callers' ConsoleKit session
# Defaults env_keep += "XDG_SESSION_COOKIE"
##
## Uncomment to enable special input methods. Care should be taken as
## this may allow users to subvert the command being run via sudo.
# Defaults env_keep += "XMODIFIERS GTK_IM_MODULE QT_IM_MODULE QT_IM_SWITCHER"
##
## Uncomment to enable logging of a command's output, except for
## sudoreplay and reboot. Use sudoreplay to play back logged sessions.
# Defaults log_output
# Defaults!/usr/bin/sudoreplay !log_output
# Defaults!/usr/local/bin/sudoreplay !log_output
# Defaults!REBOOT !log_output
##
## Runas alias specification
##
##
## User privilege specification
##
root ALL=(ALL) ALL
## Uncomment to allow members of group wheel to execute any command
# %wheel ALL=(ALL) ALL
## Same thing without a password
# %wheel ALL=(ALL) NOPASSWD: ALL
## Uncomment to allow members of group sudo to execute any command
# %sudo ALL=(ALL) ALL
## Uncomment to allow any user to run sudo if they know the password
## of the user they are running the command as (root by default).
# Defaults targetpw # Ask for the password of the target user
# ALL ALL=(ALL) ALL # WARNING: only use this together with 'Defaults targetpw'
nobody ALL = (root) NOPASSWD: /usr/share/collectd/wlstats_gatherer.sh
