It's "/etc/sudoers.conf".
Hi Tom,
Obviously not the right one.
$ ls -al /etc/sudo.conf
-rw-r--r--. 1 root root 3953 Mar 27 01:50 /etc/sudo.conf
$ less /etc/sudu.conf
#
# Default /etc/sudo.conf file
#
# Sudo plugins:
# Plugin plugin_name plugin_path plugin_options ...
#
# The plugin_path is relative to /usr/libexec/sudo unless
# fully qualified.
# The plugin_name corresponds to a global symbol in the plugin
# that contains the plugin interface structure.
# The plugin_options are optional.
#
# The sudoers plugin is used by default if no Plugin lines are present.
Plugin sudoers_policy sudoers.so
Plugin sudoers_io sudoers.so
...
It's better to add a file, for example "/etc/sudoers.d/ifdown", with
"visudo -f /etc/sudoers.d/ifdown".
# ls /etc/sudoers.d
pkg-build
# grep -i nm-ifdown /etc/sudoers
%users ALL= NOPASSWD: /usr/libexec/nm-ifdown eno2

Better:
%users ALL=(root) NOPASSWD: /usr/libexec/nm-ifdown
I wanted the command to be specific to eno2

There's no "sudovi". There's "visudo" to edit the
configuration and
there's "sudoedit" to edit a file as another user.
I commonly will reverse letter.
:'(
does sudoedit reload the conf file when it exits?
Thank you!
