我有一个本地安装的tryton。但是从远程客户端连接不起作用。tryton 是基于 Postgre SQL 构建的，从文档中我认为问题的本质就在那里。
编辑：原来问题既不是 PostgreSQL 也不是 trytond.conf 脚本本身，而是我需要在 Windows Azure 上的虚拟机设置中为端口 8000 添加一个端点。请参阅http://xmodulo.com/ 2012/12/how-to-open-ports-on-windows-azure-vm.html。但是，下面关于 trytond.conf 文件的答案也是正确的。
在 /etc/trytond.conf 我输入了 tryton 服务器的 IP 地址：
#This file is part of Tryton. The COPYRIGHT file at the top level of
#this repository contains the full copyright notices and license terms.
[options]
# This is the hostname used when generating tryton URI
#hostname =
# Activate the json-rpc protocol
jsonrpc = 23.97.165.118:8000
#ssl_jsonrpc = False
（这是一个示例 IP）
运行常见问题解答中的检查：trytond 运行正确：
监听端口：
但是，没有通过互联网从客户端连接。
我希望互联网上任何地方的每个客户端都能够连接（不是最好的安全性，但用户的 IP 会改变，所以没有办法避免这种情况）。
我必须在 /etc/postgresql/9.1/main/pg_hba.conf 中输入什么？
什么需要进入 postgresql.conf？在哪一个？用“whereis postgresql.conf”搜索会发现几个版本：
root@Tryton:~# whereis postgresql.conf
postgresql: /etc/postgresql /usr/lib/postgresql /usr/share/postgresql
非常感谢您提前提供的帮助。
编辑：这是配置文件。在服务器上本地运行正常，但无法通过互联网连接 tryton 客户端。
