[Nfd-dev] autoconfig connects me to spurs (UCLA) instead of aleph (REMAP)

[Gusev, Peter]

hi Junxiao,

here’s another example - I use guest certificate /ndn/edu/ucla/%40GUEST/gpeetonn%40gmail.com<http://40gmail.com> which supposed to incur connection to spurs (UCLA), but ndn-autoconfig connects to aleph (REMAP), or is it expected?
I attached wireshark trace file.

$ ndn-autoconfig
Trying multicast discovery...

Hi Peter

ndn-autoconfig has 4 stages, using different methods to determine which router to connect.
Can you provide a Wireshark capture while running ndn-autoconfig, so that we can see which method is being used?

Yours, Junxiao

I believe aleph is expected for certificates like /ndn/edu/ucla/remap/<username>, right?
