我目前正试图保护我的一个Linux的盒子。 我希望设备只允许那些拥有ssh私钥的系统访问。 为了做到这一点，我做了什么（不幸的是，在我看来，似乎机制不工作，任何人都可以ssh进入）
在我的Mac上
使用ssh-keygen生成1个ssh密钥。 文件密钥被写入名为mykeys和mykeys.pub
2 – 然后将mykeys.pub复制到设备的path/.ssh/authorized_keys 。 我不得不创build.ssh文件夹和authorized_keys文件。 这是我做的
cat mykeys.pub >> ~/.ssh/authorized_keys
然后我重命名我的私钥mykeys，似乎我仍然可以login。 最初没有密码设置。为什么仍然授予我访问权限的任何build议，即使我已经重新命名了私钥
更新：
以下是我尝试过的一些事情
A-我将文件（mykeys和mykeys.pub）移出〜/ .ssh B-我从known_hosts中删除了设备的ip
我仍然能够通过SSH连接到设备这是我得到的输出

默认情况下，你的ssh客户端将尝试使用~/.ssh所有密钥进行授权。 关键文件被命名的是不重要的。 如果你想testing这个，你需要把你的私钥移出~/.ssh目录。
