팔로우 후이 튜토리얼SSH 공개 키 인증을 설정하기 위해 비밀번호 없는 로그인이 작동하지 않는 것 같습니다. 항상 비밀번호 인증으로 리디렉션됩니다.
내가 알 수 있는 한, 공개 키를 서버의authorized_keys 줄에 올바르게 복사했으며 뒤에 오는 "이메일" 주소도 제거했습니다.
저는 Windows 컴퓨터를 실행하고 있지만 git bash 터미널을 통해 SSH를 사용하고 있습니다.
chmod 700 .ssh; chmod 640 .ssh/authorized_keysbob 사용자로 서버에서 명령을 실행했습니다.
귀하의 도움에 크게 감사하겠습니다. 감사해요.
출력은 ssh -vvv: bob@myserver다음과 같습니다.

고쳐 쓰다:이번에는 cygwin을 사용하여 키 생성을 시도했는데 튜토리얼에 설명된 출력(하단의 임의 키 아트)이 제공되었지만 작동하지 않았습니다.
답변1
동료로부터 이 말을 듣고 /var/log/*저는 인증 시도가 로그인될 것이라고 추측했습니다 /var/log/secure. 문제는 다음과 같습니다.
Apr 1 14:31:21 MYSERVER sshd[11980]: Authentication refused: bad ownership or modes for directory /home/bob
Apr 1 14:34:18 MYSERVER sshd[11987]: Connection closed by 123.123.123.123
이 오류는 사용자 디렉터리가 rwx그룹 등이 아닌 사용자 자신으로만 구성될 수 있기 때문에 발생합니다.
이 문제는 bob다음으로 로그인하고 명령을 실행한 chmod 700 /home/bob후 개인 키를 통해 putty로 인증함으로써 해결되었습니다!
답변2
나는 cygwin에 대해 아무것도 모르지만 이 튜토리얼의 제목은 다음과 같습니다.ssh-keygen 및 ssh-copy-id를 사용하여 SSH 비밀번호 없는 로그인을 수행하는 3단계.
막상 해보면 대략 이런 식으로 설정이 되어 있습니다. 나는 ssh-copy-id명령 대신 명령을 사용하는데 cat훨씬 더 간단하다고 생각합니다.
$ ssh-copy-id -i ~/.ssh/id_rsa.pub remote-host
