我可以通过 Web GUI 登录网络上的一台机器，我的登录名和密码正确，但 SSH 不正确。有三台这样的设备，只有两台有这个问题。
我确信我输入的密码正确。
这是我的详细输出。

在此之前...我尝试删除 RSA 数据...得到了相同的结果：
AmandaLindsMBP:~ mandalin$ ssh root@bOx
The authenticity of host 'box (192.168.1.5)' can't be established.
RSA key fingerprint is SHA256:3dc+LoHQi+nd2s6OYEQzf4chnSPV6Lp/EdIMwgKn7hQ.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'box' (RSA) to the list of known hosts.

答案1
检查 sshd_config 中的选项。如果您想以 身份登录，则PermitRootLogin必须将此选项设置为。yesroot
阅读man sshd_config以获取更多信息。
