  • OpenSSH_for_Windows_7.6p1, LibreSSL 2.6.4

现象

虚拟机启动后运行 vagrant ssh 出错, 相关错误信息如下 vagrant ssh - --v:

debug1: Trying private key: D:/Docker/.vagrant/machines/default/virtualbox/private_key
debug3: Bad permissions. Try removing permissions for user: S-1-5-11 on file D:/Docker/.vagrant/machines/default/virtualbox/private_key.

问题分析

openssh 客户端连接虚拟机时对 private_key 文件权限进行检查发现它可被其他用户访问

解决方法

在 private_key 文件的属性 / 安全中设置所有者为当前用户并取消所有继承, 当前用户完全控制
