[SOLVED] sudo does not ask for my password

Crb999 · 01-13-2017, 07:44 AM

I have used visudo to add myself to the sodoers list

Code:

root ALL=(ALL) ALL
crb999 ALL=(ALL) ALL

It does odd unexpected things!

If I type

Code:

crb999@linux-dxa1:~> NetworkManager

I get

Code:

Absolute path to 'NetworkManager' is '/usr/sbin/NetworkManager', so running it may require superuser privileges (eg. root)

if I use

Code:

crb999@linux-dxa1:~> sudo NetworkManager

I get

Code:

NetworkManager is already running (pid 5692)

But if I try to sudo 'reboot' I get this

Code:

crb999@linux-dxa1:~> sudo reboot
root's password:

I am never asked for my own password but, despite the use of sudo I am asked root's password to reboot.

What am I missing?

when giving yourself root permissions it would be best to follow the others that laid it out in how to do it. By assinging your username to one of the groups that are assigned to get root privileges not by user name specify.

it is because you are not attached to sudo within your sudoers file and perhaps the group itself as well is why it is doing what it is doing.

you used your user name yes?

look and see the bold text to get an idea of what you should be doing.

## 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

##
## 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 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
##

##
## User privilege specification
##
root ALL=(ALL) ALL

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

[OR]

## Same thing without a password
%wheel ALL=(ALL) NOPASSWD: ALL

[OR]

## 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'

## Read drop-in files from /etc/sudoers.d
## (the '#' here does not indicate a comment)
#includedir /etc/sudoers.d
anon ALL=(ALL) NOPASSWD: ALL

now add your user to the group selected to give root permissions.

Code:

su
password
#usermod -aG wheel userName
or
#usermod -aG sudo userName

log out then back in again. Done!

Hi BW-userx, thanks.

I have removed my user name as you suggest and added groups then add my user to those groups.

But the key was commenting out the Defaults targetpw

All ok now

Thaks
