원격 시스템에서 키를 업데이트했는데도 내 SSH 연결이 승인되지 않은 이유는 무엇입니까?

내 로컬 컴퓨터에 공개 키가 저장되어 있습니다.

.ssh/id_rsa.pub

원격 시스템에 로그인할 수 있도록 다음 명령을 사용하여 이 키를 복사합니다 ssh-copy-id.

ssh-copy-id user@remote-host

원격 호스트에서는 로컬 시스템 정보 .ssh/authorized_keys로 ssh-dss시작 하고 끝나는 두 줄이 파일에 추가된 것을 볼 수 있습니다 .ssh-rsa

그러나 이제 다음을 사용하여 원격 컴퓨터에 로그인하면

ssh user@remote-host

아직도 비밀번호를 묻고 있어요. 왜 그런 겁니까? 어떻게 해결하나요?

• 파일 권한이 authorized_keys정확합니다.
• 결과는 다음과 같습니다 ssh -v.
