SSH 액세스를 얻을 수 없습니다: "권한이 거부되었습니다(공개 키)"

나는 보통 사용한다테미우스Mac에서 Debian 서버로 SSH를 통해 연결했는데 지금까지는 훌륭하게 작동했습니다. 이제 단지 호기심에서 제3자가 개입하지 않고 내장된 Mac SSH 클라이언트를 사용해 보았습니다.

내용은 이렇습니다~/.ssh/config내 Mac에서:

Host stalingrad
    Hostname xxx.xxx.xxx.xxx
    User root
    Port 22
    IdentityFile ~/.ssh/digital_ocean_id_rsa.pub
    IdentitiesOnly yes

내 맥을 확인해 봤는데~/.ssh/digital_ocean_id_rsa.pub내 Debian 상자와 일치합니다./root/.ssh/authorized_keys

또한 VPS에서 다음 명령을 실행하십시오.

$ chmod 700 /root/.ssh
$ chmod 600 /root/.ssh/authorized_keys 
$ /etc/init.d/ssh restart

좋아, SSH를 시도해 보자:

ssh [email protected]

나는 이것을 얻었다:

SSH가 지정된 개인 키 파일을 읽지 못한 것 같습니다.number_ocean_id_rsa. 대신 이름이 "id_"로 시작하는 개인 키 파일 묶음을 읽으려고 시도합니다. 어떻게 되어가나요?
