使用“OpenSSH_8.4p1 Debian-5+deb11u1，OpenSSL 1.1.1n”，我想连接到远程主机，但无论我怎么尝试，它总是将登录恢复为 root。配置文件已重命名，以确保未应用任何用户选项。我得到的唯一提示是这一行：
debug1: Authenticating to 10.1.0.2:22 as 'root'
- 编辑 -
为了提供更多信息，这里有一个调试输出，直到 SSH 决定以 root 身份进行身份验证，尽管被告知不要这样做。

如您所见，没有应用任何配置文件选项。最让我困惑的是，在使用相同 ssh 客户端版本的其他主机上，它可以正常工作。我仍然认为我遗漏了一些基本的东西。有什么想法吗？
谢谢。

抱歉，占用了您宝贵的时间...我已经找到导致此现象的原因：
alias ssh='ssh -l root -o "PreferredAuthentications publickey,password"'
不知道包在 /etc/bash.bashrc 中设置了这个别名。
亲切的问候...
