Corba Event Client ETIMEDOUT

时间：2010-12-11 19:14:07

标签： python linux corba

我使用omniOrb和Python构建了一个CORBA事件服务客户端。我在Java客户端遇到了同样的问题。我非常肯定我正在经历与这篇文章相同的事情，因为我的strace看起来非常相似，但他没有解释他是如何修复的：Java's 'tnameserv' takes 3+ minutes to be "Ready", why?

底线是我的客户端启动但由于双方都存在ETIMEDOUT错误，因此从未接收到来自服务器的事件。非常感谢任何指导！

提前致谢！

修改

不幸的是，更新ip6tables（也不是iptables）不起作用。

看来我能够远程调用返回数据，但是一旦IT想要启动响应（事件），就会导致此问题（请参阅下面的日志开头）

这是我从strace的日志...

2 个答案:

答案 0 :(得分：0)

我通过在防火墙脚本中添加以下行来修复此问题

 ip6tables -A INPUT -i lo -j ACCEPT

答案 1 :(得分：0)

我最终弄清楚，因为我在与服务器不同的子网上，ORB发布了错误的IP地址，并且在偶数触发时无法找出返回我的客户端的路由。

我最终更改了/etc/omniORB.cfg中的配置文件，并将“endPointPublish”属性的值更改为服务器子网上的IP地址！
