我已经在 Centos 上安装了 freeradius。
MySQL 数据库中填充了一些用于测试的数据，并且配置了 freeradiusd.conf 和 sql.conf。
RADIUS 服务器能够连接 MySQL 数据库，我可以从中验证用户身份。我还配置了一个远程 RADIUS 客户端，该客户端与我的强制门户和 RADIUS 服务器配合使用，但是，只有当我在 中配置了客户端的 IP 地址时，它才有效/etc/raddb/clients.conf。使用 MySQL“nas”表时，它不起作用。
换句话说，freeradius 似乎没有从 MySQL 数据库查询我的 nas 表。
在我的/etc/raddb/mods-enabled/sql文件中，有以下内容：
# Table to keep radius client info
nas_table = "nas"
# Set to 'yes' to read radius clients from the database ('nas' table)
read_clients = yes
在我的 nas 表中，我有以下内容：
id nasname shortname type ports secret server community description
1 xx.xx.xx.xx NULL other NULL testing123
default NULL RADIUS Client
...其中 xx.xx.xx.xx 是我的 RADIUS 客户端的正确 IP 地址。
当我尝试通过强制门户登录时，使用 freeradius 在调试模式下运行，我收到以下信息：

任何帮助都将不胜感激！PS：我尝试将 nas 表中的短名称更改为与 ip 相同的名称，但仍然不起作用
