OpenDDS participants could not discovery each other

Rcently, I try to communicate by using OpenDDS-3.12. I want to communicate other two hosts which located other WAN. But, participants could not discovery each other. How can I solve this problem??

Here is my communication enviroments:

I have two hosts. HostA and Host B is my Destktop(Ubuntu 16.04). Also, two hosts has public IP address(visible) and disable firewall. I already checked whether the specific port number was available by telnet command.

I used OpenDDS-3.12 and $OpenDDS_HOME/tests/DCPS/Messenger 's example.

In HostA, enable

$ DCPSInfoRepo -ORBListenEndpoints iiop://:12345

Subscriber operate like this:

$ ./subscriber -DCPSInfoRepo <HostA's IP>:12345 -DCPSConfigFile sub_multicast.ini

In HostB, Directory is same and publisher operate like this:

$ ./publisher -DCPSInfoRepo <HostA's IP>:12345 -DCPSConfigFile pub_multicast.ini

Publisher's return error message here:

# ./publisher -DCPSInfoRepo <HostA's IP>:12345 -DCPSConfigFile pub_multicast.ini
Starting publisher

What is the proper configuration to discover other each WAN host??

Hope you help me.

Solution

  • Use rtps_uni.ini for both publisher and subscriber
