sudoers.in

##
## Sample 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.

## Please consider adding local content in /etc/sudoers.d/ instead of
## directly modifying this file.

##
## See the sudoers man page for the details on how to write a sudoers file.

##
## Defaults specification
##
## Preserve editor environment variables for visudo.
## To preserve these for all commands, remove the "!visudo" qualifier.
Defaults!@visudo@ env_keep += "SUDO_EDITOR EDITOR VISUAL"
##
## Preserve EDITOR environment variables for all users in the sudo group.
## This allows running arbitrary commands, but sudo members are root
## equivalent anyway.
#Defaults:%sudo env_keep += "SUDO_EDITOR EDITOR VISUAL"
##
## 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.
@secure_path_config@Defaults secure_path="@secure_path@"
##
## 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 preserve proxy settings from user environments of root
## equivalent users (group sudo)
# Defaults:%sudo env_keep += "http_proxy https_proxy ftp_proxy all_proxy no_proxy"
##
## Uncomment to preserve environment variables for grep
# Defaults:%sudo env_keep += "GREP_COLOR"
##
## Uncomment to preserve git related environment. While you shouldn't
## normally run git as root, you need to with etckeeper
# Defaults:%sudo env_keep += "GIT_AUTHOR_* GIT_COMMITTER_*"
##
## Uncomment to preserve Debian-related environment variables. root 
## won't have sensible values for them.
# Defaults:%sudo env_keep += "EMAIL DEBEMAIL DEBFULLNAME"
##
## Uncomment to allow root to use the calling user's ssh agent
## transparently. This enabled "sudo scp" or "sudo rsync"
# Defaults:%sudo env_keep += "SSH_AGENT_PID SSH_AUTH_SOCK"
##
## Uncomment to allow root to use the calling user's gpg agent
## transparently. This enabled "sudo scp" or "sudo rsync"
# Defaults:%sudo env_keep += "GPG_AGENT_INFO"
##
## Uncomment to disable "use_pty" when running commands as root.
## Commands run as non-root users will run in a pseudo-terminal,
## not the user's own terminal, to prevent command injection.
# Defaults>root !use_pty
##
## Uncomment to run commands in the background by default.
## This can be used to prevent sudo from consuming user input while
## a non-interactive command runs if "use_pty" or I/O logging are
## enabled.  Some commands may not run properly in the background.
# Defaults exec_background
##
## Uncomment to send mail if the user does not enter the correct password.
# Defaults mail_badpass
##
## Uncomment to enable logging of a command's output, except for
## sudoreplay and reboot.  Use sudoreplay to play back logged sessions.
## Sudo will create up to 2,176,782,336 I/O logs before recycling them.
## Set maxseq to a smaller number if you don't have unlimited disk space.
# Defaults log_output
# Defaults!/usr/bin/sudoreplay !log_output
# Defaults!/usr/local/bin/sudoreplay !log_output
# Defaults!REBOOT !log_output
# Defaults maxseq = 1000
##
## Uncomment to disable intercept and log_subcmds for debuggers and
## tracers.  Otherwise, anything that uses ptrace(2) will be unable
## to run under sudo if intercept_type is set to "trace".
# Defaults!DEBUGGERS !intercept, !log_subcmds
##
## Uncomment to disable intercept and log_subcmds for package managers.
## Some package scripts run a huge number of commands, which is made
## slower by these options and also can clutter up the logs.
# Defaults!PKGMAN !intercept, !log_subcmds
##
## Uncomment to disable PAM silent mode.  Otherwise messages by PAM
## modules such as pam_faillock will not be printed.
# Defaults !pam_silent

##
## Runas alias specification
##
Runas_Alias	OP = root, operator
Runas_Alias	DB = oracle, sybase
