[Nfd-dev] problem with prefix propagation

[Nikos Fotiou]

Hi all and happy new year.

I am having trouble implementing prefix propagation. I have a machine (M) which can connect to the testbed node mmlab-aueb-1.mmlab.edu.gr. Furthermore, using https://ndncert.named-data.net I have received and installed in (M) a certificate for the name /ndn/gr/aueb/fotiou. In (M), I am running NFD 0.7.1-3-g9ab43e67, installed from source, using the sample configuration. 

So in (M) ndnsec list -c outputs:
 
* /ndn/gr/aueb/fotiou
  +->* /ndn/gr/aueb/fotiou/KEY/%EDA%B0%0E%FF%19%C9%AD
       +->* /ndn/gr/aueb/fotiou/KEY/%EDA%B0%0E%FF%19%C9%AD/NA/%FD%00%00%01v%FA%9E%3F%9F
       +->  /ndn/gr/aueb/fotiou/KEY/%EDA%B0%0E%FF%19%C9%AD/self/%FD%00%00%01v%FA%9C6%DD

Then, in (M) I run the following commands:

> nfdc face create udp://mmlab-aueb-1.mmlab.edu.gr
> nfdc route add /localhop/nfd udp://mmlab-aueb-1.mmlab.edu.gr

Finally in (M), I execute

> ndnpingserver /ndn/gr/aueb/fotiou/test

NFD in (M) outputs the following:

What am I missing?

Best,
