[solved] How to enable password request for restart and shutdown?

Hi,

I'm neither a Linux nor an Arch Linux newbie, but inexperienced regarding this particular issue.
I want to enable password request for restart and shutdown and want to know if I'm mistaken, because trial and error might become to time-consuming while working on a project.

I read https://wiki.archlinux.org/index.php/Al … o_shutdown.

$ ls -hAl /usr/bin/shutdown
lrwxrwxrwx 1 root root 9 Apr 22 03:02 /usr/bin/shutdown -> systemctl

If I try to run $ shutdown -hP 28 or $ shutdown -c nothings happens, I need to run $ sudo shutdown -hP 28 and $ sudo shutdown -c and type a password. That's the way I want it.

If I e.g. run $ shutdown -r now no password is needed. I want to disable this. It should behave the same way as shutdown -hP/-c behave. I want to type
$ sudo shutdown -r now or $ sudo systemctl reboot etc. and then the password should be required.

$ sudo grep -vn "#" /etc/sudoers | grep [[:blank:]]
72:root ALL=(ALL) ALL
73:rocketmouse ALL=(ALL) ALL

The user "rocketmouse" should have all permissions after typing a password, but not without typing the password.

IIUC what's written at https://wiki.archlinux.org/index.php/Polkit, I need to edit

$ pkaction | grep login
org.freedesktop.accounts.set-login-option
org.freedesktop.login1.attach-device
org.freedesktop.login1.flush-devices
org.freedesktop.login1.hibernate
org.freedesktop.login1.hibernate-ignore-inhibit
org.freedesktop.login1.hibernate-multiple-sessions
org.freedesktop.login1.inhibit-block-idle
org.freedesktop.login1.inhibit-block-shutdown
org.freedesktop.login1.inhibit-block-sleep
org.freedesktop.login1.inhibit-delay-shutdown
org.freedesktop.login1.inhibit-delay-sleep
org.freedesktop.login1.inhibit-handle-hibernate-key
org.freedesktop.login1.inhibit-handle-lid-switch
org.freedesktop.login1.inhibit-handle-power-key
org.freedesktop.login1.inhibit-handle-suspend-key
org.freedesktop.login1.power-off
org.freedesktop.login1.power-off-ignore-inhibit
org.freedesktop.login1.power-off-multiple-sessions
org.freedesktop.login1.reboot
org.freedesktop.login1.reboot-ignore-inhibit
org.freedesktop.login1.reboot-multiple-sessions
org.freedesktop.login1.set-user-linger
org.freedesktop.login1.suspend
org.freedesktop.login1.suspend-ignore-inhibit
org.freedesktop.login1.suspend-multiple-sessions
org.freedesktop.machine1.login

IOW I need to replace every yes and no etc. with auth_admin in $ grep -v lang /usr/share/polkit-1/actions/org.freedesktop.login1.policy.

Am I mistaken?

Regards,
Ralf

You'll need to create a rules file which uses javascript.
https://wiki.archlinux.org/index.php/Po … tion_rules

// /etc/polkit-1/rules.d/10-admin-shutdown-reboot.rules

polkit.addRule(function(action, subject) {
    if (action.id == "org.freedesktop.login1.power-off" ||
        action.id == "org.freedesktop.login1.power-off-ignore-inhibit" ||
/*...SOME_MORE_IDS_HERE...*/ 
    ) {
        // return polkit.Result.AUTH_ADMIN_KEEP;
        return polkit.Result.AUTH_SELF_KEEP;
    }
});

Re: [solved] How to enable password request for restart and shutdown?

I copy pasted your code to a file named "10-admin-shutdown-reboot.rules" in the directory "/etc/polkit-1/rules.d/" and rebooted my computer. I still get the same error message "Forbidden". The output in the error log is still the same:

E [21/Jun/2015:13:54:16 -0400] [Client 17] Returning HTTP Forbidden for CUPS-Get-Devices (no URI) from localhost
E [21/Jun/2015:13:54:16 -0400] [CGI] CUPS-Get-Devices request failed with status 401: Forbidden

Re: [solved] How to enable password request for restart and shutdown?

Not sure if you've tried this or not, but you could remove your user from the "power" group and replacing it with "root" (in /etc/group) so that you need to make a sudo request to run power (shutdown/restart) commands.  You'd also need to reduce the current permissions for your user though (e.g., %wheel group rather a than current unrestricted access).

/etc/group
...
wheel:x:10:root,username
...
power:x:98:root
...

Thank you :)

this solved the issue:

# cat /etc/polkit-1/rules.d/10-admin-shutdown-reboot.rules 
polkit.addRule(function(action, subject) {
    if (action.id == "org.freedesktop.login1.power-off" ||
        action.id == "org.freedesktop.login1.power-off-ignore-inhibit" ||
        action.id == "org.freedesktop.login1.power-off-multiple-sessions" ||
        action.id == "org.freedesktop.login1.reboot" ||
        action.id == "org.freedesktop.login1.reboot-ignore-inhibit" ||
        action.id == "org.freedesktop.login1.reboot-multiple-sessions"
    ) {
        return polkit.Result.AUTH_SELF_KEEP;
    }
});
