当服务器中的用户没有login到SSH给：权限被拒绝（公钥）

我正在使用公钥authenticationbuild立一个SSH服务器。 为此，我使用了这个教程： http : //www.g-loaded.eu/2005/11/10/ssh-with-keys/

我能够通过SSHlogin。 但是，这只有当我保持用户login到服务器（这意味着我必须在服务器上input我的用户名和密码，并保持login状态）。 如果我注销用户在服务器上，当我尝试通过SSHlogin它给出：“权限被拒绝（公钥）”。

我的问题是…是否真的需要保持用户login到服务器使用SSH公钥身份validation？ 或者我做错了什么？

谢谢！

• 如何检查一个ssh密钥的密码是否只用公钥设置？
• 自动发送公钥到github账户
• 从没有.pem文件的日志logging中保护EC2实例
• 设置SSHD来处理多个密钥对
• ssh通过公共密钥authentication为用户pipe理的NIS

附加信息：使用

ssh [email protected] -v 

我得到以下输出（当没有用户login到服务器）。
