Hi Alan, thanks for your reply, I try to find the FAQ in the website https://wiki.freeradius.org/guide/FAQ, but I only find one part about stuff: Of course a Makefile is suited perfectly for this kind of stuff. In fact, I read all the FAQ, but only a question about PAP and CHAP authentication, not EAP AKA authentication. Could you please help to check it, thank you very much. ------------------ 原始邮件 ------------------ 发件人: "Alan DeKok" <aland@deployingradius.com>; 发送时间: 2021年9月22日(星期三) 晚上8:49 收件人: "FreeRadius users mailing list"<freeradius-users@lists.freeradius.org>; 抄送: "老咪"<93327349@qq.com>; 主题: Re: reply: The problem when I run freeRadius server 4.0 in master: Failed adding new socket to network event loop: Failed inserting filters for FD 15: EFAULT: Bad address On Sep 21, 2021, at 11:59 PM, 老咪 via Freeradius-Users <freeradius-users@lists.freeradius.org> wrote: > Thanks for your help, we solved the problem by update the libkquequ version to 2.4.0.
