I am trying to use sudo to work around the following bug
I posted:
ifdown access denied with USERCTL=yes
https://bugzilla.redhat.com/show_bug.cgi?id=1828100
I wish they'd fix the bug, but it does not seems like it
is every going to get any attention.
So anyway, I fired up `sudovi` and added the following
at the end of /etc/sudo.conf`:
## Allows members of the users group to down eno2
%users ALL=/usr/libexec/nm-ifdown eno2
Now when I run it from the command line, I get:
$ /usr/libexec/nm-ifdown eno2
Error: failed to load connection: access denied.
Questions:
1) I thought `sudovi` caused sudo to reread sudo.conf
on its exit. Am I mistaken? And if so, how do I
force a reread?
2) what is wrong with the syntax of the command I added
to sudo.conf?
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
Ah ha! This worked:
%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
Then
$ sudo /usr/libexec/nm-ifdown eno2
Connection 'eno2' successfully deactivated (D-Bus active path:
/org/freedesktop/NetworkManager/ActiveConnection/2)
and `sudovi` did cause the re-read as I thought
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!

May I suggest creating a two line script file?
Name it "eno2down"
#!/bin/bash
/usr/libexec/nm-ifdown eno2
Then your sudo command can be "sudo eno2down".
Store it in /usr/local/bin for everybody.
