我通过 apt-get 在 Ubuntu 10 中安装了 freeradius。
使服务器运行后。本地测试有效：
yozloy@SNDA-192-168-21-78:/usr/bin$ echo "User-Name=testuser,Password=123456" | radclient 127.0.0.1:1812 auth testing123 -x
Sending Access-Request of id 245 to 127.0.0.1 port 1812
User-Name = "testuser"
Password = "0054444944"
rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=245, length=20
但是在远程机器上，radius服务器机器好像没有响应：
root@SNDA-192-168-14-131:/home/yozloy# echo "User-Name=testuser,Password=123456" | radclient 58.215.164.98:1812 auth testing123 -x
Sending Access-Request of id 36 to 58.215.164.98 port 1812
User-Name = "testuser"
Password = "0054444944"
Sending Access-Request of id 36 to 58.215.164.98 port 1812
User-Name = "testuser"
Password = "0054444944"
Sending Access-Request of id 36 to 58.215.164.98 port 1812
User-Name = "testuser"
Password = "0054444944"
radclient: no response from server for ID 36 socket 3
这是我的配置文件：
clients.conf
client 58.215.164.98 {
ipaddr = 58.215.164.98
secret = testing123
require_message_authenticator = no
}
用户
testuser CLeartext-Password := "0054444944"
更新配置文件（我实际上并没有改变任何东西） radiusd.conf
proxy_requests = yes
$INCLUDE proxy.conf
$INCLUDE clients.conf
thread pool {
start_servers = 5
max_servers = 32
min_spare_servers = 3
max_spare_servers = 10
max_requests_per_server = 0
}
modules {
$INCLUDE ${confdir}/modules/
$INCLUDE eap.conf
}
instantiate {
exec
expr
expiration
logintime
}
$INCLUDE policy.conf
$INCLUDE sites-enabled/

如果我错了请纠正我，但是，针对您的 RADIUS 服务器 (SNDA-192-168-21-78) 的 SNDA-192-168-14-131 的 IP 地址不是 58.215.164.98，是吗？ 如果不是，那就是你的答案。您的 RADIUS 服务器将仅适用于在 clients.conf 中配置的具有正确机密的 NAS。
尝试将 192.168.14.131（如果它是该主机的 IP 地址）添加到 clients.conf 然后再试。
我有类似的问题，请参阅下面的结果 radsniff
