could it be that the face is pointing to a TCP socket instead?
Did you see TCP traffic with tcpdump? I never used ndnfs, but after
glancing into the code, it seems that ndnfs is (capable of)
creating a face on the server-side with an underlying TCP socket.
This could explain why you didn't see UDP traffic, although the files
get synced (?)

The files are successfully sync'ed with the end host over a three hop wireless network, but when I run tcpdump to monitor the traffic in the network, I don't see any UDP packets during the sync (I do see UDP packets when I run ndnchunks). I can see mDNS packets.
