Python Corba事件客户端ETIMEDOUT

我已经用omniOrb和Python构建了一个CORBA事件服务客户端。我对Java客户机也有同样的问题。我很确定我和这篇文章经历了同样的事情，因为我的strace看起来非常相似，但他没有确切解释他是如何修复的：

底线是我的客户端启动了，但由于双方都出现了ETIMEDOUT错误，因此从未从服务器接收到事件。非常感谢您的指导

提前谢谢

编辑

不幸的是，更新ip6tables（或iptables）无法工作

似乎我能够获得远程呼叫返回数据，但一旦它想要启动响应（事件），就会导致此问题（请参阅下面日志的开头）

这是我在斯特拉斯的日志

我通过在防火墙脚本中添加以下行修复了此问题

 ip6tables -A INPUT -i lo -j ACCEPT

我最终发现，由于我在与服务器不同的子网中，ORB发布了错误的IP地址，无法找到返回我客户端的路径
