linux – sshd忽略authorized_keys并继续尝试authorized_keys2

我刚刚将我的公钥上传到服务器,确保权限是正确的,当我尝试记录它时,只是拒绝它.

在sshd_config中启用loglevel DEBUG后,我得到：

它继续尝试authorized_keys2(我虽然到处都弃用了)但是它确实在某个时候打开了authorized_keys(带有我的键的正确文件)然后再说完全没有关于它并返回到authorized_keys2

这有什么不对？

我的sshd_config中有：

PubkeyAuthentication yes
AuthorizedKeysFile      .ssh/authorized_keys

并且该文件中没有authorized_keys2字符串.是的,sshd在测试之前重新启动.

我想我可以使用authorized_keys2,但想了解这里发生了什么.有什么线索吗？
