Sudoers file with wheel NOPASSWD not working.

My /etc/sudoers file

I am trying to use sudo command without entering password, so I changed the sudoers file
by typing 'sudo EDITOR=vim visudo' than uncommented wheel group.Also added my user
to wheel group but when I use sudo command it is still requiring me for a password, need help here.

## 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"

## 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 use a hard-coded PATH instead of the user's to find commands
# Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
##
## 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.
# Defaults log_output
# Defaults!/usr/bin/sudoreplay !log_output
# Defaults!/usr/local/bin/sudoreplay !log_output
# Defaults!REBOOT !log_output

##
## Runas alias specification

## Uncomment to allow members of group wheel to execute any command
# %wheel ALL=(ALL) ALL

## Same thing without a password

Have you logged out after adding yourself to wheel?

Also, would be nice if you wrap your code within

[code]...[/code]

* did not work for some reason.However etc sudoer.d includes 3 files.

[burak@thinkpad] <~> ➤ sudo cat /etc/sudoers.d/burak                         
burak ALL=(ALL) ALL
[burak@thinkpad] <~> ➤ sudo cat /etc/sudoers.d/ctdb                          
Defaults!/etc/ctdb/statd-callout	!requiretty

rpcuser		ALL=(ALL) 	NOPASSWD: /etc/ctdb/statd-callout
[burak@thinkpad] <~> ➤ sudo cat /etc/sudoers.d/aurbuilder                    
aurbuilder ALL=(ALL) NOPASSWD: ALL
root ALL=(aurbuilder) NOPASSWD: ALL

I have manually edited the

/etc/sudoers.d/burak

file, from this->

burak ALL=(ALL) ALL

to this ->

burak ALL=(ALL) NOPASSWD: ALL

.
Now it is working, I can run sudo commands without password.
However I still can not get it, why editing sudoers file did not work both for

%wheel ALL=(ALL) NOPASSWD: ALL

, and

burak ALL=(ALL) NOPASSWD: ALL

in the first place, because it is the right and conventional way to do it

"later" matches override earlier definitions, that file/directory is by default included last, so of these three rules the last one is what ultimately defined your rights.

Remove /etc/sudoers.d/burak - the user trumps the group.
Edit: fuck.

Thank you everyone, now how can I lock the thread

seth · 2021-09-14 20:22:14

Mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
