[Nfd-dev] certificate for interacting with NDN testbed

[Nikos Fotiou]

Yeap! Now I received the certificate from mmlab1-aueb and it was
successfully installed in the keychain.

Nikos,

 

we have updated a lot on the Testbed today. Could you try again and see if
it all works now?

 

Thanks,

John

Hi, 

 

Everything is now updated to the latest version from source. I am receiving
the certificate but ndncert-client crashes with the following error:

 

terminate called after throwing an instance of
'boost::exception_detail::clone_impl<boost::exception_detail::error_info_inj
ector<std::runtime_error> >'

  what():  Cannot parse replied certificate

Aborted (core dumped)

 

Best,

Nikos

Hi Nikos

 

There has been a packet format change related to ForwardingHint and
Delegation.

Your ndn-cxx, NFD, and ndncert versions are incompatible, which causes
decoding error.

 

Please install all from https://nfd-nightly.ndn.today
<https://nfd-nightly.ndn.today/>  or all from latest source code.

Do not mix different versions.

See NFD-nightly instructions for how to switch between installation methods.

 

Yours, Junxiao

I found it. 

 

I can see the challenge in the log file. I enter the correct challenge and
then ndncert-client outputs:

 

>> Certificate has already been issued, downloading certificate...

>> Interest timeout

 

In the nfd output I see the following:
