SSH 공개 키 인증

ssh를 사용하여 Macbook Air 클라이언트를 인증하여 Raspberry Pi 서버에 연결하는 데 문제가 있습니다. 이것이 작동하지 않는 이유에 대한 제안이 있습니까?

내가 시도한 것 :

• ssh 키를 작성하고 공개 키를 서버 ~/.ssh/authorized_keys폴더에 복사
• 포트 777로 포트 전달 활성화 (SSH에 해당 포트 사용)
• 내 서버에서 ~/.ssh및 ~/.ssh/*폴더에 대한 권한 설정
• 내 서버 /etc/ssh/sshd_config파일 에서 RSAAuthentication 및 PubkeyAuthentication 사용

클라이언트 측에 기록합니다 :

서버 측에 기록합니다 :

>>> cat /var/log/auth.log
sshd[4115]: User pi authorized keys /home/pi/.ssh/authorized_keys is not a regular file
sshd[4115]: Connection closed by 192.168.0.5

나는 당신의 사용법을 잘못 이해했다고 생각합니다 authorized_keys.

authorized_keyspubkey 파일을 넣는 디렉토리 가 아닙니다 .

authorized_keys 모든 pubkey를 포함하는 일반 파일입니다.

키가 하나만 있으면 파일 이름을 바꿀 수 있습니다.

mv id_rsa.pub authorized_keys

키가 두 개 이상인 경우 cat을 사용하여 해당 키를 파일에 연결할 수 있습니다.

cat id_rsa.pub ios_id_rsa.pub >> authorized_keys
