ejabberd - 无法从非本地 ip 在 ejabberd 中注册

问题描述

位于 192.168.7.5 IP 的 LAN 主机上的 ejabberd 服务器。在面向 Internet 的计算机上，防火墙将端口重定向5222, 5269, 5443, 5280, 3478, 5349, 49152:65535到ejabberd服务器。

我已经阅读了有关创建帐户的垃圾邮件，但我不确定该选择什么。考虑过但允许使用验证码trusted_network: loopback服务 从所有 IP 进行注册（稍后将在防火墙基础上进行限制）。

尝试从Gajim注册时，该过程似乎一直在尝试。在 ejabberd 的日志中：

2021-07-27 16:53:42.970 [info] <0.383.0>@ejabberd_listener:accept:273 (<0.581.0>) Accepted connection 11.12.13.14:51267 -> 192.168.7.5:5222

这是我的ejabberd.yml：

除此之外，对于反向代理（nginx）

server {
        listen       5280 ;
        server_name  example.cyou;
        root /usr/local/www/nginx/example.cyou;
        index  captcha.html;

        location /captcha {
               proxy_set_header Host $host;
               proxy_set_header X-Forwarded-For $remote_addr;
               proxy_pass http://192.168.7.5:5280;
        }
    }

所以我的问题是：

  1. 如何更正配置
  2. 如果 ejabberd 为多个主机提供服务，如何mod_register根据 ejabberd 服务的主机放置不同的选项，例如 example.cyou 具有所述选项，但对于主机 foobar.org 仅开放注册一个本地网络，并registration_watchers根据每个主机指定。

解决方案

  1. 如果 ejabberd 服务于多个主机，如何根据 ejabberd 服务的主机将不同的选项放置在 mod_register 中，例如，例如 example.cyou 具有所述选项，但对于主机 foobar.org 仅开放注册对于本地网络并根据每个主机指定registration_watchers。

使用 append_host_config。https://docs.ejabberd.im/admin/configuration/basic/#virtual-hosting中有一个示例， 它为每个虚拟主机配置不同的 mod_muc。
