尽管 PermitRootLogin 为是，但使用 root 用户在 SSH 到 Debian 8.5 中的权限被拒绝

Question

我正在尝试使用root用户通过 SSH 连接到我的 Debian 8.5 。密码正确，因为我可以使用本地控制台登录到 Debian。PermitRootLogin等于yesin/etc/ssh/sshd_config并且服务器多次重新启动以确保进行此更改。

grep PermitRootLogin /etc/ssh/sshd_config
PermitRootLogin yes

我怎么解决这个问题？

运行sudo tail /var/log/auth.log：

Nov 29 07:40:06 mydeb sshd[2530]: User root from ::1 not allowed because none of user's groups are listed in AllowGroups
Nov 29 07:40:06 mydeb sshd[2530]: input_userauth_request: invalid user root [preauth]

编辑/etc/ssh/sshd_config并添加root以AllowGroups. 该行应该是这样的：

AllowGroups sudo sshuser root

ssh通过以下命令重启服务：

service ssh restart
