ERROR: No default identity

[WangwzZB]

When I run the pingall.py and any other experiment, it shows that:

root@ubuntu:~/mini-ndn-demo/mini-ndn# sudo python examples/nlsr/pingall.py Using topology file /usr/local/etc/mini-ndn/default-topology.conf Creating network Adding controller Adding hosts: a b c d Adding switches:

So why does it tell me," No default identity”. Is there something I forgot to install?

If you install dummy key chain patch, this message will go away. We brought dummy keychan from ndnsim make experiments faster and scale. Installing dummy-key chain is optional and won't cause any problem. It comes from the following line: https://github.com/named-data/mini-ndn/blob/master/minindn/minindn.py#L99 which checks if the dummy key chain is installed in the system or not. And if it's not, and also if there is no default identity installed in the system you get that message. We will suppress the message in some later patch. Thanks for pointing out.

Thank you！ I try to apply the ndn-cxx-dummy-keychain-from-ndnsim.patch, but that failed. Then I find that I just install the latest version of ndn-cxx(0.7.0 )which was realeased on 14 Jan and not suit the ndn-cxx-dummy-keychain-from-ndnsim.patch, so I think a update is needed. Thanks for your working!

[agawande]

Yes, patch is old. Can you please test https://gerrit.named-data.net/c/mini-ndn/+/6175 @awlane

[WangwzZB]

I apply the new patch, and no errors shows.

root@ecs-b437:~/mini-ndn/mini-ndn# git -C ndn-src/ndn-cxx/ apply /root/mini-ndn/mini-ndn/patches/ndn-cxx-dummy-keychain-from-ndnsim.patch

But when I want to reinstall the ndn-cxx, the flowing errors spring up.

[agawande]

Can you try ./waf distclean && ./waf configure && ./waf in ndn-cxx? Also this is latest ndn-cxx github master right?

[WangwzZB]

Thanks. I install successfully, and It shows，Security will be disabled. What does that means,? How to make the node creat with Security?

Yes, that patch disables security in ndn-cxx. Remove the patch if you want security enabled.

It will (still) give you the no default identity error - but you can ignore that (we will suppress that in some other change soon as Saurab mentioned).

[WangwzZB]

Thank you！
