如何向公众开放ejabberd服务器

%%%
%%%     Debian ejabberd configuration file
%%%     This config must be in UTF-8 encoding
%%%
%%% The parameters used in this configuration file are explained in more detail
%%% in the ejabberd Installation and Operation Guide.
%%% Please consult the Guide in case of doubts, it is available at
%%% /usr/share/doc/ejabberd/guide.html

%%% This configuration file contains Erlang terms.
%%% In case you want to understand the syntax, here are the concepts:
%%%
%%%  - The character to comment a line is %
%%%
%%%  - Each term ends in a dot, for example:
%%%      override_global.
%%%
%%%  - A tuple has a fixed definition, its elements are
%%%    enclosed in {}, and separated with commas:
%%%      {loglevel, 4}.
%%%
%%%  - A list can have as many elements as you want,
%%%    and is enclosed in [], for example:
%%%      [http_poll, web_admin, tls]
%%%
%%%  - A keyword of ejabberd is a word in lowercase.
%%%    The strings are enclosed in "" and can have spaces, dots...
%%%      {language, "en"}.
%%%      {ldap_rootdn, "dc=example,dc=com"}.
%%%
%%%  - This term includes a tuple, a keyword, a list and two strings:
%%%      {hosts, ["jabber.example.net", "im.example.com"]}.
%%%

%%%   ===================================
%%%   OVERRIDE OPTIONS STORED IN DATABASE

%%
%% Override global options (shared by all ejabberd nodes in a cluster).
%%
%%override_global.

%%
%% Override local options (specific for this particular ejabberd node).
%%
%%override_local.

%%
%% Remove the Access Control Lists before new ones are added.
%%
%%override_acls.

%%
%% loglevel: Verbosity of log files generated by ejabberd.
%% 0: No ejabberd log at all (not recommended)
%% 1: Critical
%% 2: Error
%% 3: Warning

%% send live notifications to those Jabber accounts.
%%
%%{watchdog_admins, ["bob@example.com"]}.


%%%   ================
%%%   SERVED HOSTNAMES

%%
%% hosts: Domains served by ejabberd.
%% You can define one or several, for example:

%%
%% (This option is defined by debconf earlier)
%% {hosts, ["localhost"]}.

%%
%% route_subdomains: Delegate subdomains to other Jabber server.

%% to allow communication with a Jabber server called im.example.org.
%%
%%{route_subdomains, s2s}.

%% max_fsm_queue: Enable limiting of lengths of "message queues"

%% The default value is an atom 'undefined' which specifies no limiting.
%%
%% When specified globally, this option limits the message queue lengths
%% for all ejabberd_c2s_in and ejabberd_service listeners,
%% as well as for outgoing s2s connections.
%%
%% This option can also be specified as an option for ejabberd_c2s_in

%% The default value is 300 seconds (5 minutes). 
%%
%% The reconnection algorythm works like this: if connection fails,
%% ejabberd makes an initial random delay between 1 and 15 seconds,
%% then retries, and if this attempt fails, makes another delay,

%%%   ==============
%%%   DATABASE SETUP

%% ejabberd uses by default the internal Mnesia database,
%% so you can avoid this section.
%% This section provides configuration examples in case
%% you want to use other database backends.
%% Please consult the ejabberd Guide for details about database creation.

%% NOTE that ejabberd in Debian supports "out of the box"
%% only mnesia (default) and ODBC storage backends.
%% Working with MySQL and PostgreSQL DB backends requires
%% building and installation of the corresponding Erlang modules,
%% not distributed as a part of ejabberd.
%% Refer to /usr/share/doc/ejabberd/README.Debian for details.

%%
%% MySQL server:
%%
%%{odbc_server, {mysql, "server", "database", "username", "password"}}.
%%
%% If you want to specify the port:
%%{odbc_server, {mysql, "server", 1234, "database", "username", "password"}}.

%%
%% PostgreSQL server:
%%
%%{odbc_server, {pgsql, "server", "database", "username", "password"}}.
%%
%% If you want to specify the port:
%%{odbc_server, {pgsql, "server", 1234, "database", "username", "password"}}.
%%
%% If you use PostgreSQL, have a large database, and need a
%% faster but inexact replacement for "select count(*) from users"
%%
%%{pgsql_users_number_estimate, true}.

%%
%% ODBC compatible or MSSQL server:
%%
%%{odbc_server, "DSN=ejabberd;UID=ejabberd;PWD=ejabberd"}.

%%
%% Number of connections to open to the database for each virtual host
%%
%%{odbc_pool_size, 10}.

%%
%% Interval to make a dummy SQL request to keep alive the connections
%% to the database. Specify in seconds: for example 28800 means 8 hours

%%%   ====================
%%%   ACCESS CONTROL LISTS

%%
%% The 'admin' ACL grants administrative privileges to Jabber accounts.
%% You can put as many accounts as you want.

%%%   ============
%%%   ACCESS RULES

%% Define the maximum number of time a single user is allowed to connect:
{access, max_user_sessions, [{10, all}]}.

%% Maximum number of offline messages that users can have:
{access, max_user_offline_messages, [{5000, admin}, {100, all}]}. 

%% This rule allows access only for local users:
{access, local, [{allow, local}]}.

%% Only non-blocked users can use c2s connections:
%{access, c2s, [{deny, blocked},
%          {allow, all}]}.

% TODO: Testing. Allow all
{access, c2s, [{allow, all}]}.

%% For all users except admins used "normal" shaper
{access, c2s_shaper, [{none, admin},
              {normal, all}]}.

%% For all S2S connections used "fast" shaper
{access, s2s_shaper, [{fast, all}]}.

%% Only admins can send announcement messages:
{access, announce, [{allow, admin}]}.

%% Only admins can use configuration interface:
{access, configure, [{allow, admin}]}.

%% Admins of this server are also admins of MUC service:
{access, muc_admin, [{allow, admin}]}.

%% All users are allowed to use MUC service:
{access, muc, [{allow, all}]}.

%% No username can be registered via in-band registration:
%% To enable in-band registration, replace 'deny' with 'allow'
% (note that if you remove mod_register from modules list then users will not
% be able to change their password as well as register).
% This setting is default because it's more safe.
%{access, register, [{deny, all}]}.
%TODO: testing. allow registration
{access, register, [{allow, all}]}.

%% By default frequency of account registrations from the same IP
%% is limited to 1 account every 10 minutes. To disable put: infinity
%%{registration_timeout, 600}.

%% Everybody can create pubsub nodes
{access, pubsub_createnode, [{allow, all}]}.

%%
%% Define specific Access rules in a virtual host.
%%
%%{host_config, "localhost",
%% [
%%  {access, c2s, [{allow, admin}, {deny, all}]},
%%  {access, register, [{deny, all}]}

%%%   ================
%%%   DEFAULT LANGUAGE

%%
%% language: Default language used for server messages.
%%
{language, "en"}.

%%
%% Set a different default language in a virtual host.
%%
%%{host_config, "localhost",
%% [{language, "ru"}]

验证连接是否真正通过服务器.

在一个互联网连接盒使用telnet,nc或类似的命令来验证连接到服务器的作品众所周知的端口.做

$ telnet 123.123.10.210 5222

然后键入一些乱码并按Enter键发送它 - 您应该从服务器收到一个XML节,告诉您发送了格式错误的流并指示流关闭(退出telnet会话,按Crl-)然后输入q并点击输入).

如果此命令挂起,然后超时或完全失败,则表明存在网络连接问题.

当你检查它时,有一个tcpdump运行实例来查看是否有数据包进来并且回复出来真的很方便:

# tcpdump -n -i eth0 'tcp and (port 5222 or port 5269)'

(替换您的Internet连接接口的名称而不是eth0).

您必须为XMPP域设置正确的DNS.

也就是说,如果您的用户有JID example.domain.com,则Internet上的每个人都应该能够向他们的DNS服务器询问如何使用XMPP联系该域中JID的用户.这是使用SRV记录完成的.维护DNS服务器的DNS服务器example.domain.com必须有两个DNS记录:

_xmpp-client._tcp.example.domain.com指向接受客户端连接的服务器的主机和端口(因此它们应该123.123.10.210和5222).

_xmpp-server._tcp.example.domain.com指向接受服务器连接的服务器的主机和端口(因此它们应该123.123.10.210和5269).

更多信息在这里.

跑

$ host -t srv _xmpp-client._tcp.gmail.com
$ host -t srv _xmpp-server._tcp.gmail.com

了解它应该是什么样子.

这里需要注意的另一件事是,如果您的服务器位于DMZ(不是直接连接到Internet但是由NAT设备调解),则应该更多地涉及防火墙设置.但在深入研究之前,请检查连接,如上所述.
