Hi Damon,

There are no errors.
Talker is publishing message but Listener is not getting it.
They are not in same channel I mean Listener and Talker cant reach each
other.

I suppose by giving same master uri, both should be able to communicate.

is xmlRpcPort is used in this communication?

Thanks and Regards
Abhishek Verma
