Frequently Asked Question: Missing Samples

Question: I am having difficulty receiving samples across multiple machines on the same subnet. Do you have any information on firewall settings and/or logging/debugging options to diagnose handshaking?

Answer: Firewalls are commonly a problem (especially with default Linux and Windows configurations). For a quick test, you can try turning off the firewall all together - to see if that's the problem.

Another quick check is to add listeners for "publication_matched" (DataWriter), "subscription_matched" (DataReader), and "inconsistent_topic" (Topic). This will give you an indication if the problem is in the discovery or matching of entities.

Another useful tool is wireshark: if you can start a capture and then start your DDS applications, let it run for a few seconds and then save off the capture file to send to us, we can take a look at what is (and is not) making it onto the wire. This “quick look” is a free service provided to all evaluators of our CoreDX DDS products!
