Passwordless root access in qubes
|
||
=================================
|
||
|
||
|
||
The rationale behind passwordless root in qubes is set out
|
||
:doc:`here </user/security-in-qubes/vm-sudo>`. Implementation is by the
|
||
qubes-core-agent-passwordless-root package.
|
||
|
||
This page sets out the configuration changes made, with (not necessary
|
||
complete) list of mechanisms depending on each of them:
|
||
|
||
1. sudo (``/etc/sudoers.d/qubes``):
|
||
|
||
.. code:: bash
|
||
|
||
Defaults !requiretty
|
||
%qubes ALL=(ALL) ROLE=unconfined_r TYPE=unconfined_t NOPASSWD: ALL
|
||
|
||
(...)
|
||
|
||
|
||
|
||
- Easy user -> root access (main option for the user).
|
||
|
||
- ``qvm-usb`` (not really working, as of R2).
|
||
|
||
|
||
|
||
2. PolicyKit (``/etc/polkit-1/rules.d/00-qubes-allow-all.rules``):
|
||
|
||
.. code:: bash
|
||
|
||
//allow any action, detailed reasoning in sudoers.d/qubes
|
||
polkit.addRule(function(action,subject) { if (subject.isInGroup("qubes")) return polkit.Result.YES; });
|
||
|
||
|
||
PAM (``/etc/pam.d/su.qubes`` or ``/usr/share/pam-configs/su.qubes``)
|
||
``auth sufficient pam_succeed_if.so use_uid user ingroup qubes``
|
||
|
||
- NetworkManager configuration from normal user (``nm-applet``).
|
||
|
||
- Updates installation (``gpk-update-viewer``).
|
||
|
||
- User can use pkexec just like sudo Note: above is needed mostly
|
||
because Qubes user GUI session isn’t treated by PolicyKit/logind
|
||
as “local” session because of the way in which X server and
|
||
session is started. Perhaps we will address this issue in the
|
||
future, but this is really low priority. Patches welcomed anyway.
|
||
|
||
|
||
|
||
3. Empty root password:
|
||
|
||
- Used for access to ‘root’ account from text console
|
||
(``qvm-console-dispvm``) - the only way to access the VM when GUI
|
||
isn’t working.
|
||
|
||
- Can be used for easy ‘su -’ from user to root.
