여러 Linux 서버에 대해 SSH를 만드는 방법은 무엇입니까?

고쳐 쓰다*

Virtual Box 내에서 취약한 웹 애플리케이션을 실행하는 두 개의 Linux 서버 CentOS 7 및 Debian 6이 있습니다. 호스트 OS는 Kali Linux이고 호스트 전용 어댑터 설정을 통해 두 가상 머신에 모두 연결되어 있습니다. CentOS에 성공적으로 ssh할 수 있지만 Debian에 ssh하면 호스트 확인에 실패했다는 메시지가 나타납니다. 제 질문은 오류가 발생하지 않거나 여러 가상 머신에 연결하지 않고 어떻게 debian에 ssh를 보낼 수 있느냐는 것입니다.
