![ssh 公钥身份验证:首次登录仍要求输入密码](https://linux22.com/image/75955/ssh%20%E5%85%AC%E9%92%A5%E8%BA%AB%E4%BB%BD%E9%AA%8C%E8%AF%81%EF%BC%9A%E9%A6%96%E6%AC%A1%E7%99%BB%E5%BD%95%E4%BB%8D%E8%A6%81%E6%B1%82%E8%BE%93%E5%85%A5%E5%AF%86%E7%A0%81.png)
我已经使用 设置了公钥身份验证ssh
,但发生的情况是,当我第一次登录时,它仍然要求输入密码,任何后续登录(同时保持第一次登录处于活动状态)都不会要求输入密码。我不知道任何设置会产生这种行为。有人知道为什么我第一次被提示输入密码吗?
该密码肯定不是访问密钥的密码,因为我ssh
从服务器收到登录消息,并要求我输入user@remote
密码。
编辑:输出ssh -vvv user@remote
:
首次登录:

答案1
这可能是由于您的主目录(以及密钥)在登录期间无法访问所致。这可能是由于您的主目录在登录后从网络驱动器(在共享系统上)安装或您的主目录被加密(通常是工作站的安装)造成的。
解决这个问题很复杂,但我会看看一些讨论。解决方案是将AuthorizedKeysFile
密钥移至其他可访问的位置或我们的密钥全局存储 ( /etc/security/authorized_keys
),或某种 SSO 管理系统(IPA、LDAP),该系统将从目录服务器获取密钥(是的,可以是本地的) )。取决于您对目标系统的控制程度。
也许最好的解决方案是将密钥存储在其他位置,更改以下值sshd_config
:
AuthorizedKeysFile /etc/ssh/%u/authorized_keys
进一步讨论可在超级用户或者在这里Unix 和 Linux,或描述帮助.Ubuntu。
