[Nfd-dev] NDN certificate & auto prefix propagation

Tue Jan 24 09:17:46 PST 2017

Dear Junxiao,

  OK. I fixed it. The automatic prefix propagation's key chain contained an invalid certificate (/tmp-identity/...). Not sure what it is since I never created it. Is it fine to delete all tmp-identity, then? Anyway, after deleting it, it works fine.

  Also, what is a good command to check validity of certificates? 'ndnsec list' does not provide much information.

Best wishes,

Dear Junxiao,

  Hi. Please find the attached.
  The log file is the result of 'sudo tcpdump -s 0 port 6363 -i eth0 -w log.pcap' at the producer side.

  In the file, 72.36.112.82 is the illinois ndn node and 128.174.246.46 is the producer node.

Best wishes,
Jongdeog Lee (JD)

I am using ndn-cxx 0.4.0 now due to compatibility issue.
Let me try the latest version and see what happen.

If it does not work, I will attach the log file.

HI Jongdeog

Can you attach tcpdump logs (.pcap) instead of ndndump text output?
ndndump cannot show Data payload so it's useless to see what's the error.

Yours, Junxiao

Hi Junxiao,

  Thanks. I forgot to do 'nfdc register /localhop/nfd udp4://ndnx.cs.illinois.edu<http://ndnx.cs.illinois.edu>'.
  Unfortunately, even with that, it is not working (cannot find the prefix in the router status page)

  Here is the ndndump result at the illinois ndn node after executing ndnpingserver.
