ndndump

ndndump is a traffic analysis tool that captures Interest, Data, and Nack packets on the wire and displays brief information about captured packets.

Usage example:

1. start NFD on the local machine
2. create a UDP tunnel to a remote machine
3. run sudo ndndump
4. cause some NDN traffic to be sent/received on the tunnel
5. observe the output of ndndump
