为什么我在以 sudo 身份运行命令时没有收到密码提示,即使我的用户组甚至不在 sudoers 文件中?

为什么我在以 sudo 身份运行命令时没有收到密码提示,即使我的用户组甚至不在 sudoers 文件中?

我在/etc其中具有以下权限:

drwxr-xr-x  23 root  wheel  2560 Jul  1 20:47 etc

$ whoami
pierre
$ groups
pierre

sudo如果我想touch foo进去,我就必须跑/etc

我想要的是提示root输入 的密码,但即使在更改此行之后,我也没有收到提示:

%wheel ALL=(ALL) NOPASSWD: ALL

进入sudo visudo

%wheel ALL=(ALL) PASSWD: ALL

不过,考虑到我当前的用户不在组中,这甚至不重要wheel......我已经确保该root帐户设置了密码(通过使用设置sudo passwd root)。

我使用的是 FreeBSD 10.3-RELEASE-p11 云服务器。

非常感谢任何关于为什么我没有收到密码提示的见解!

这是我的 suoders 文件添加@jesse_b 的答案中建议的行。

## sudoers file.

## This file MUST be edited with the 'visudo' command as root.
## Failure to use 'visudo' may result in syntax or file permission errors

##
## Locale settings

答案1

这是一种不明显的语法,因为它看起来像注释,但 sudoers 允许您使用指令在另一个目录中包含规则:

#includedir /usr/local/etc/sudoers.d

您的 nopasswd 规则可能存在于该目录中的文件中。

答案2

尝试将以下行添加到/etc/sudoers

Defaults rootpw

我认为 sudo 通常会提示输入当前用户的密码,只要该用户是wheel组的成员。
