[Mini-NDN] About minindn nlsr running error

[李怿曈 Yitong LI]

Hi Alex,

Many thanks for your reply. I have another question. When I first installed mini-non, I’ve checked “nfd-status”, it seemed nfd works well at that time. However, now I found that nfd didn’t work and I’ve tried “nfd-start”. It gave me an error below. I wonder how to solve the problem of nfd. Thanks a lot!

Good morning,
I believe this is an issue with the nfdc helper code not handling the returned output for "face-updated" which is not treated as a failure internally in nfdc, we had observed this prior and noted it did not seem to be causing issues. I will try and push an update ASAP as I believe this has caused confusion multiple times and I was able to find the apparent cause. However, I am reasonably confident that you are safe to ignore it until then.

Subject: [Mini-NDN] About minindn nlsr running error

Hi all,

I met an error when building an example to run nlsr on minindn. At last nlsr indeed converges. But there’re two faces fail to register before. I’ve attached the log below.
