Hi Alan, Thanks for your help, we solved the problem by update the libkquequ version to 2.4.0. Now I run the v4.0 like this, thank you very much. However, I can't find the way to use EAP MD5 or EAP AKA authentication, I modify the the conf files of the server, but it doesn't work. Could you please help to tell me how to configure it, thanks a lot. ------------------ 原始邮件 ------------------ 发件人: "FreeRadius users mailing list" <aland@deployingradius.com>; 发送时间: 2021年9月18日(星期六) 晚上10:26 收件人: "FreeRadius users mailing list"<freeradius-users@lists.freeradius.org>; 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 18, 2021, at 10:13 AM, Noel Butler <noel.butler@ausics.net> wrote: > > On 18/09/2021 22:40, Alan DeKok wrote: > >> CentOS 7 is very old, and is no longer getting updates. > > centos 7 is getting updates, its 6.2 that recently stopped getting them, 7 will be supported for a few more years OK.
