[gentoo] sudo输对密码但老说try again

karfield

用的是Gentoo， su和sudo都是emerge的。

一开始su都用不了，参考网上说的，一般只修改/etc/pam.d/su和/bin/su的权限就解决了，我改了，还是没用，后来在gentoo论坛里找了很久，用了：
USE="-pam" emerge su
才把它解决了。

现在又遇到没法用sudo的问题：
$ sudo -l
Password:
Sorry, try again.
Password:
Sorry, try again.
Password:
Sorry, try again.
sudo: 3 incorrect password attempts

我的sudo配置：

$ ls -l /usr/bin/sudo
---s--x--x 2 root root 148360 Mar 25 12:35 /usr/bin/sudo

/etc/sudoers的配置只包含了：
root ALL=(ALL) ALL
%wheel ALL=(ALL) ALL
## (我的帐号是wheel组的)

/etc/pam.d/sudo的配置：

auth    include         system-auth
account include         system-auth
password        include         system-auth
session include         system-auth

/etc/pam.d/system-auth的配置

auth            required        pam_env.so
auth            required        pam_unix.so try_first_pass likeauth nullok
auth            optional        pam_permit.so

account         required        pam_unix.so
account         optional        pam_permit.so

password        required        pam_cracklib.so difok=2 minlen=8 dcredit=2 ocredit=2 retry=3
password        required        pam_unix.so try_first_pass use_authtok nullok sha512 shadow
password        optional        pam_permit.so

session         required        pam_limits.so
session         required        pam_env.so
session         required        pam_unix.so
session         optional        pam_permit.so

哪位高手、大侠碰到过这样的问题，帮忙指条明路。。。。


附上我的emerge --info

你sudo输入的是root密码还是当前用户自己的密码？？？

karfield

root密码和当前用户的密码都设置成一样了
