chpasswd는 chroot 디렉터리의 변경 사항을 적용합니다.

내 컴퓨터에 해당 버전이 debootstraped있고 비밀번호를 변경하고 싶습니다.wheezyArchlinuxroot

echo "root:toor" | chpasswd --root /home/containers/wheezy/

하지만 오류가 발생합니다.

chpasswd: PAM: Permission denied

root내 로컬 사용자에서는 잘 작동합니다( --root옵션 없음).

이 man페이지에는 다음 사항이 명확하게 명시되어 있습니다.

-R, --root CHROOT_DIR
CHROOT_DIR 디렉터리에 변경 사항을 적용하고 CHROOT_DIR 디렉터리의 구성 파일을 사용합니다.

그럼 내가 뭘 잘못하고 있는 걸까요? 어떻게 PAM참여하나요? 다른 방법이 있나요?

# echo "root:toor" | sudo strace -f -efile,execve chpasswd --root /home/containers/wheezy/

아래는 불평을 시작하는 출력입니다 chpasswd.

chpasswd대상 컨테이너에 예상되는 파일이 다음을 제외한 다른 많은 언어로 찾을 수 있음 을 발견했습니다 .영어:

# find /usr/share/locale/ -iname '*Linux-PAM.mo*'

/usr/share/locale/pt_BR/LC_MESSAGES/Linux-PAM.mo
/usr/share/locale/ta/LC_MESSAGES/Linux-PAM.mo

참고: 대상 컨테이너 와 동일한 기대치는 en_GB무엇 chpasswd입니까 ? uk..

필요한 파일이 포함된 것으로 보이는 패키지를 다시 설치해 보았습니다.

apt-get install --reinstall libpam-runtime login locales locales-all

그러나 그것은 전혀 도움이 되지 않습니다.

Debian Jessie마지막으로 동일한 컨테이너에서 동일한 명령을 실행했습니다.일했다. 이 경우 는 다른 구현으로
해결되었습니다 .WheezyArchlinuxchpasswd

이 문제에 대한 가장 좋은 휴대용 솔루션은 @Peter Cordes가 제안한 솔루션이라고 생각합니다.

echo 'root:toor' | chroot /home/containers/wheezy/ /usr/sbin/chpasswd
