sudo does not work.
I have installed Arch onto a USB key, using BTRFS.
The output of "sudo" is:
$ sudo
sudo: unable to stat /etc/sudoers: Permission denied
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
$ ls -l /etc/sudoers
-r--r----- 1 root root 2849 May 18 15:00 /etc/sudoers
$ lsattr /etc/sudoers
--------------- /etc/sudoers
$ strace -u ross sudo true
Hello all,
I manage some HP-UX 11.31 servers. I have some users that have sudo access. All of them belong to the 'sudoers' user group.
Following the wiki's advice, I installed ubuntu-zfs.
i screwed up big time.
I would like to run a command with temporary group membership but it seems that I don't have permission to do that.
I've set up sudo not to prompt for password by editing the sudoers file:
myuser ALL=(ALL:ALL) NOPASSWD: ALL
And it works fine, running sudo with no password prompting. But when entering sudo -v I noticed that it prompted for password, only once.
During an installation, as usual, we create our main user account, and then we can do sudo commands with it without problem.
Now, when I created another account, and I wanted to do sudo, it gave me error that the account is not in the sudoers file. In that file I found out that users in %admin and %sudo groups can gain root privileges.
I think that sudo is become a wide used command with Ubuntu, where you don’t even have a root password, before that probably it was used only in some data-centers to restrict access to some commands.
sudo allows a permitted user to execute a command as the superuser or another user, as specified in the sudoers file.
I've checked the sudoers file, it passed the check, here's the setup:
#
# 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
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin
