配置代理服务
RADIUS 代理配置信息位于 /etc/radius 目录中的 proxy 文件中。
初始 proxy 文件包含示例条目。 代理文件中有三个字段：Realm Name、Next Hop IP address 以及 Shared Secret。
要配置代理规则，请从以下项中选择：
Configure Proxy Rules
List all Proxy
Add a Proxy
Change / Show Characteristics of a Proxy
Remove a Proxy
realm_name next_hop_address shared_secret选择 Add a Proxy 可显示以下屏幕。 将从面板中检索信息，并将数据附加到 /etc/radius/proxy 文件的底部。
在两个 RADIUS 服务器之间，代理链的每个中继段都使用共享的秘密。 共享的秘密包含在 /etc/radius/proxy_file 中。 对于链中的每个代理中继段，共享秘密应该是唯一的。
有关创建共享密钥的更多信息，请参阅 /etc/radius/clients 文件。
要添加代理，请从下面所示的字段中选择：
Add a Proxy
*Realm Name [] (max 64 chars)
*Next Hop IP address (dotted decimal) [xx.xx.xx.xx]
*Shared Secret [] (minimum 6, maximum 256 chars)
Remove a Proxy 选项会显示域名列表。 该列表显示在弹出屏幕中，并且用户必须选择一个域名。 选择了名称后，除去域之前会显示验证弹出屏幕。
以下示例是 radiusd.conf 文件的代理配置信息部分：

# this server services. #
