我正在使用在 Cygwin、Windows 7、VMware 虚拟机、Windows 8.1 上运行的 Dropbear SSH。在我的物理操作系统上，我有 Cygwin，我正在尝试使用 Cygywin 上的 openssh 进行无密码登录。为了构建它，我必须传递LIBS="-lcrypt -lz"make 才能让它获取 libcrypt 和 zlib。
构建并安装它后，我在物理操作系统上生成了客户端的密钥对，ssh-keygen并将其复制到~/.ssh/authorized_keys每个 Dropbear 的联机帮助页中，然后我使用 启动了 Dropbear dropbear -EF。在确认 VM 上的 Dropbear 守护程序正常启动并显示在 Windows 任务管理器上后，我尝试连接到 VM 并收到一条消息，显示Permission denied (publickey)。我尝试禁用除公钥登录之外的所有登录选项，重新编译Dropbear，但仍然无法工作。
使用详细选项运行客户端会给出以下结果：
