我有 debian 9 服务器并且想要设置带有 radius 身份验证的 Xl2tp。
当我添加plugin radius.so我的 ppp 选项时，它会尝试读取/etc/radiusclient，但不幸的是我没有libfreeradius-clientdebian stretch 存储库上的包。
有人对此有什么想法吗？

答案1
apt-get install freeradius-utils libpam-radius-auth
并将您的配置编辑为：/etc/freeradius/3.0/clients.conf
答案2
libfreeradius-客户端已弃用并替换为libradcli4
配置文件夹也从 更改/etc/radiusclient为/etc/radcli
并且某些属性也发生了更改，例如：
root@localhost#grep NAS-IP /etc/radcli/dictionary
ATTRIBUTE NAS-IP-Address 4 ipv4addr
