[Nfd-dev] [Ndn-interest] Problem with retrieving packets on GENI testbed

[Mohammad Alhowaidi]

I found that the ndndump is listening on the wrong interface since consumer
and producer have multiple interface connected to them, I corrected that by
using ndndump -i, but I still don't get the data back to the consumer even
the interest is arrived to the producer
ndndump output on the consumer:

1507311365.838279 From: 10.10.7.1, To: 10.10.7.2, Tunnel Type: UDP,
INTEREST:
/ndn/f1?ndn.MinSuffixComponents=3&ndn.MaxSuffixComponents=3&ndn.ChildSelector=1&ndn.Nonce=8742671

ndndump output on the producer:

sudo ndndump -i eth1

INCOMPLETE-PACKET, size: 1472

it seems the packets returns from the producer is incomplete-packet type,
any idea why?

Thanks,
Mohammad
