有人能帮我弄清楚吗？我试图在更新authorized_keys文件后禁用密码并重新连接，但每当我将PasswordAuthinition标志设置为否时，就会出现这种错误。我已经尝试过执行ssh-copy-id -i ~/.ssh/test2.pub username@hostip，其中test2是新生成的pub id。我有点不知道从哪里开始。我的本地机器似乎找不到一个名为known_hosts2的文件夹，但我知道如何继续。
- 您是否使用适当的密钥(例如
sh-copy-id -i ~/.ssh/test2 username@hostip(进行连接 - 如果你的钥匙在
/home/clive/.ssh/authorized-keys - 文件是否得到充分的保护
例如：
chmod 700 .ssh
chmod 600 .ssh/authorized_keys
还要检查服务器端调试日志(通常在/var/log中(，以了解导致登录失败的原因。
