저는 Cygwin, Windows 7, VMware 가상 머신, Windows 8.1에서 실행되는 Dropbear SSH를 사용하고 있습니다. 내 실제 OS에는 Cygwin이 있고 Cygywin에서 openssh를 사용하여 비밀번호 없는 로그인을 시도하고 있습니다. 이를 빌드하려면 LIBS="-lcrypt -lz"make를 전달하여 libcrypt 및 zlib를 가져와야 합니다.
빌드하고 설치한 후 물리적 OS에서 클라이언트의 키쌍을 생성 ssh-keygen하고 각 Dropbear의 맨페이지에 복사한 ~/.ssh/authorized_keys다음 dropbear -EF. VM의 Dropbear 데몬이 정상적으로 시작되고 Windows 작업 관리자에 나타나는 것을 확인한 후 VM에 연결하려고 하면 이라는 메시지가 나타납니다 Permission denied (publickey). 공개 키 로그인을 제외한 모든 로그인 옵션을 비활성화하고 Dropbear를 다시 컴파일해 보았지만 여전히 작동하지 않습니다.
verbose 옵션을 사용하여 클라이언트를 실행하면 다음과 같은 결과가 나타납니다.
