在我的Ubuntu 12.04 VM上,当在本地使用时,应用程序(Tryton)在端口8000上正常运行。但是,从外面我无法通过Internet连接到端口8000。 (事先,我使用的是具有用户友好端点配置的Windows Azure。)
在本地运行的Netstat报告该端口正在侦听: (我把这个VM称为“NoConnection”,以区别于下面)
root@NoConnection:~# netstat -tupan | grep 8000
tcp 0 0 127.0.0.1:8000 0.0.0.0:* LISTEN
10051/python
tcp 0 0 127.0.0.1:8000 127.0.0.1:58160 ESTABLISHED
10051/python
tcp 0 0 127.0.0.1:58160 127.0.0.1:8000 ESTABLISHED
10860/python
使用nmap进行本地检查似乎还可以:

端口8000就是Tryton ERP,但是nmap并不知道。
但是,来自其他计算机的 nmap扫描 * 不会 *找到开放端口:

我想这对于Tryton App来说并不是特别的,而是Linux VM的端口设置方式。
作为参考,在正常配置Tryton并通过端口8000访问的工作的不同VM(在Windows Azure上)上,端口8000的netstat输出显示:
root@WorksRight:~# netstat -tupan | grep 8000
tcp6 0 0 :::8000 :::* LISTEN
1310/python

在未连接的VM上显示:

当然,是的,我已经检查过,两台机器都在特定于应用程序的trytond.conf文件中打开了端口:
#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]
# Activate the json-rpc protocol
jsonrpc = *:8000
答案 0 :(得分:0)
事实证明,应用程序服务器刚刚没有正确重新启动,因此无法读取配置文件的更改。
更详细的答案如下: Tryton client doesn't connect via Internet port 8000
