What should /etc/sudoers contain normally? [duplicate]

Question

When I run sudo visudo , what should it contain? Please give me an example of what it should have normally for a sudo user.

Answer 1

Here's what I change on new installations:

$ sudo cat /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults    env_reset, timestamp_timeout=120, pwfeedback
#Defaults    mail_badpass
Defaults    secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"
Defaults:rick !secure_path

  (... SNIP rest of file unchanged ...)

I put my changes at the top of the file. They are displayed in bold above:

• timeout makes sudo privalege last for 2 hours so I don't have retype password every 5 minutes or whatever the default is.
• pwfeedback places a * on screen with each key press during password input.
• mail_badpass stops an email being sent to my account each time I enter the sudo password incorrectly.
• !secure_path is explained here: Can I make `sudo` follow my path via CLI?
