권한은 적절한 것 같습니다. ~/.ssh로컬 워크스테이션의 폴더는 로 설정되고 700, ~/.ssh/authorized_keys원격 서버의 폴더는 으로 설정됩니다 600.

문제가 무엇인지 아시나요?

@자쿠제

$ ls -lZd ~ilya ~ilya/.ssh/ ~ilya/.ssh/authorized_keys
drwxr-x--- ilya ilya ?                                /home/ilya
drwxrwxr-x ilya ilya ?                                /home/ilya/.ssh/
-rw------- ilya ilya ?                                /home/ilya/.ssh/authorized_keys

답변1

~/.ssh소유자 이외의 누구도 폴더에 쓸 수 없습니다. 그룹 권한을 완전히 제거하면(서버에서 다음 명령) 다음을 수행할 수 있습니다.

chmod g-rwx ~ylia/.ssh
