最近,我成功地通过 OpenDDS 与同一子网中的两台主机通信。但是,我想通过公共网络或 WAN 与其他两台主机通信。它不起作用。我怎么解决这个问题??
这是我的通信环境:
我有两个主机。HostA 是 AWS(Amazon Web Service),Host B 是我的 Destktop。此外,两台主机具有公共 IP 地址并禁用防火墙。我已经通过 telnet 命令检查了特定端口号是否可用。像这样:
$ telnet <HostA IP's> 12345
这是很好的连接。
我使用了 OpenDDS-3.11 和$OpenDDS_HOME/tests/DCPS/Messenger
的示例。
在 HostA 中,启用
$ DCPSInfoRepo -ORBListenEndpoints iiop://:12345
订阅者的操作如下:
$ ./subscriber -DCPSConfigFile sub_multicast.ini
在主机 B 中,
目录是相同的订阅者,然后发布者的操作如下:
$ ./publisher -DCPSInfoRepo <HostA's IP>:12345 -DCPSConfigFile pub_multicast.ini
发布者在此处返回错误消息:
$ ./publisher -DCPSInfoRepo <HostA' IP>:12345 -DCPSConfigFile pub_multicast.ini

我做错了什么??
