我已经在 centos 6.8 上设置了一个半径服务器，并且我有一个开关，我想调用这个半径服务器进行身份验证。交换机 IP 地址是 10.2.1.4，在客户端配置文件中。这是我的客户端 conf 文件的一部分
client switch {
ipaddr = 10.2.1.4
secret = testing123
nastype = other
}
下面是我得到的错误
... adding new socket proxy address * port 55146
Listening on authentication address * port 1812
Listening on accounting address * port 1813
Listening on command file /var/run/radiusd/radiusd.sock

任何人都可以在这里帮助我吗？
