I want to communicate between two m/c on same network using DDS.

I have installed DDS on both m/cs.
Now i want to run publisher on one m/c and subscriber on other m/c.

I am trying with test.$DDS_root/DDS/tests/DCPS/Prst_delayed_subscriber


IP Address of m/c 1 : -> publisher
Ip Address of m/c 2 : -> subscriber

There are 3 things running while making communication through openDDS on single m/c.

1) InfoRepo
2) Publisher
3) Subscriber

Now suppose I want to have communication between two machines. I want
message published on one m/c by the publisher and to read the message by
the subscriber on the other m/c.

what will be the tranport configuration in sub.ini and pub.ini

1) Do I need to have the Info Repo running on both the m/c?

What will be the content of the pub.ini and sub.ini.

2) How can we run the publisher and subscriber on the self specified port?
pls help ...

I am new to DDS.

I wanted to try out some of the examples given along with Opensplice dds.
I am using the community edition of opensplice dds.

I am trying to run publisher on one machine and subscriber on another.

I have two machines configured with openspilce dds.
Both on LAN.

I tried executing the PinpPong example.

I executed Pong on one of the machine and Ping on another (with matching Read & Write partitions).

It is not working out and i am getting error on the machine where I am executing ping application. 'PING Failed : Timed out'

I read some earlier posts explaining about the networking service of dds and the default settings in the config file.

I assumed the dds will automatically find the other running dds infrastructures on network. Is this assumption incorrect?

Please let me know where I am going wrong

Thanks in advance
