과학 리눅스 6에서 sshd를 통해 연결할 수 없습니다


1

ssh를 통해 (동일한 네트워크의) 작업중 인 컴퓨터에 연결하려고합니다.

핑으로 컴퓨터에 연결할 수 있으며 ssh하려고 할 때 암호 프롬프트로 응답합니다. 그러나 비밀번호를 수락하지 않습니다.

사용자 이름과 비밀번호를 두 번 확인하고 서비스를 다시 시작했습니다. 내가 놓친 것이 있습니까?

중요한 경우 우분투 컴퓨터에서 연결하려고합니다.

디버그 출력은 다음과 같습니다. (&& (서버) ** (클라이언트)에 의해 사용자 데이터를 교환했습니다)

  1. 원격 시스템에서 / var / log / auth 또는 / var / log / secure를 확인하고 오류 또는 경고를 찾으십시오.
  2. ssh -vvv username @ server를 사용하고 출력을주의 깊게 읽으십시오.
  3. 허용 된 사용자 목록을 사용하고 있지 않은지 확인하십시오.
  4. 루트 로그인을 허용하는 옵션이 비활성화되어 있지 않은지 루트로 로그인하려는 경우 확인하십시오.
  5. 비밀번호 인증이 켜져 있고 키가 필요하지 않은지 확인하십시오.

다른 모든 방법으로 실패하면 ssh -vvv ....의 출력 또는 / var / log / auth 또는 / var / log / secure에있는 경고 / 오류가 출력됩니다.


당신의 제안에 감사드립니다. 1에서 제안 된 파일을 찾지 못했습니다. 2) 출력을 인쇄했습니다. 3/4) 루트로 로그인하지 않습니다
