[Ndn-interest] ChronoChat and its default RIB entries

I could start two ChronoChat processes from same host, and upon creating
and joining the same chatroom, they are able to chat with each other.
However, I think this message transaction is not going over the IP network,
and I am not able to see any messages on ndndump. What way we can trace
these messages using tcpdump?

I am also getting an Warning message, "Warning: no connection to hub or hub
does not support prefix autoconfig".. I am not sure what this means.

Again, I want to run this chat across two remote hosts, and the problem
mentioned earlier still exist. How can I force ChronoChat to use specific
face Id instead of picking up the default one.

Can someone please comment on this?
