[Nfd-dev] [ndn] NDN Seminar: Practical Congestion Control for NDN

[Gusev, Peter]

hi Junxiao,

I deleted this identity, restarted nfd, ndn-autoconfig and ndncon. Do you see me now?

$ grep AutoPrefix /tmp/nfd.log

Hi Peter

NFD-RIB prefers the shortest identity available, because it can register the largest possible namespace toward the end host. This has nothing to do with which identity is the default.
Your KeyChain contains an identity named ndn:/, so that NFD-RIB is trying to register ndn:/ toward your end host, with the certificate associated with this identity. That certificate is almost certainly not trusted by the testbed, thus you won’t get a successful registration.
If you change NFD-RIB loglevel to TRACE, you should be able to see the error.

You need to execute ndnsec delete ndn:/ and then restart NFD.
If necessary, you can backup the private key and certificates of that identity before deleting it.

Yours, Junxiao

hi Junxiao,

We weren’t able to make me discoverable on ndncon while connected to REMAP hub.
Can you please give any advices on troubleshooting this? It seems that we tried everything we could…

My NFD is v0.4.0 build from sources. Certificate installed is default:

$ ndnsec list
* /ndn/edu/ucla/remap/peter
  /
  /peetonn
  /ndn/edu/ucla/remap
  /ndn/edu/ucla/remap/zhehao
  /ndn/edu/ucla/remap/peter/ndncon

I ran ndn-autoconfig and here’s the grep from NFD log:

$ grep AutoPrefix /tmp/nfd.log
1464817688.388236 INFO: [AutoPrefixPropagator] Load auto_prefix_propagate section in rib section
