backuppc 서버는 원격 시스템에 루트로 로그인하여 백업 할 수 있지만 backuppc 사용자로 로그인하고 동일한 키를 사용하여 이러한 시스템에 ssh를 시도하면 다음 디버그 출력으로 키가 거부됩니다.

~/.ssh로그인 한 컴퓨터 의 권한을 확인하는 것이 좋지만 내 문제는 액세스 할 수 없다는 것입니다. 컴퓨터에서 여기에 원격으로 로그인하려고하는데 .ssh디렉토리에 대한 권한 이 설정되어 600있습니다.

/etc/hosts.allow및 /etc/hosts.deny변경되지 않았습니다.
키는이 시스템에서 문제없이 오랫동안 사용되어 왔기 때문에 생성되어 잘못된 형식으로 저장되지 않았으므로 변경되지 않아야합니다. 지금까지 나는 그것을 고치는 데 도움이되기를 희망하면서 시스템을 재부팅했지만 새로운 키를 생성하는 것이 실제로는 선택 사항이 아니기 때문에 다른 기계가 무엇인지 알지 못합니다.이 기계는 멀리 떨어져 있기 때문입니다. 누구든지 내가 어떻게해야하는지 알고 있습니까?
어떤 조언이라도 대단히 감사하겠습니다. 미리 감사드립니다.
키가 ~ / .ssh에 있다고 말합니다. /var/lib/BackupPC/.ssh/id_rsa에 대한 오류 메시지가 표시됩니다. 홈 폴더가 / var / lib / BackupPC에 있습니까?

Safado
네 그렇습니다. 이것이 backuppc가 작동하는 방식입니다. 따라서 ~ / .ssh는 backuppc 사용자로 로그인 할 때 /var/lib/BackupPC/.ssh와 동일합니다.

HAL9000
좋아, 그냥 물어봐 계정에 / var / lib의 홈 폴더가 모두있는 것을 본 적이 없습니다.

FWIW, "알 수없는 키 유형 '----- BEGIN'"메시지와 그 뒤에 오는 메시지는 오류 메시지가 아닙니다. ssh는 키 파일이 특정 형식인지 확인하고 자세한 정보를 요청했기 때문에 자세한 정보를 표시합니다.
