Listener not receiving data

I am having trouble getting a subscriber to receive data from a publisher. Both entities are on the same machine and my firewall is off.

* Subscriber has a listener with StatusMask as all().
* set NDDS_DISCOVERY_PEERS=4@shmem://
* Using HighThroughput profile.

I guess the more unusual thing about this app is that there are two domain participants with a pub on one and a subscriber on the other. Yet, they are both on the same domain's id, 0. I assume that's ok.

Problems connecting DDS applications

I'm running a DDS micro client (v 2.4.10) on a linux ARM system (compiled from source).  It produces topic data on one second intervals, and I have a windows 7 system with the Connext Pro version 5.3.0 running the Admin Console that should be able to watch the data.

Unable to discover the reader in my app [solved]

Hi all.

I’ve been developing a set of apps with one server and three different clients. Everything works fine while running all of them on the same machine. Now I put one of those clients in another machine B, connected to the same router, and the first message of this client -a login request- is never received by the server in machine A. The on_publication_matched method in the client is never executed, but in the Administration Console, the client turns from Healthy to Warning: Reader-only Topic. Topic contains only DataReaders when the message is sent.

I bring some of my application code below for further uses:

MTU and Fragmentation

Hello,

We are using a 3G cellular link to send data back from a remote device. I had a problem where I was seeing Readers/Writers being discovered by Spy, but no samples would ever come through. Upon closer inspection, it appeared that discovery wasn't in fact ever completing, although Spy showed the readers/writers. Turning on verbosity showed that there was some strange errors on type matching. Our typecode is roughly ~3-4k.
