NFD

Can you show output of

dig ns1.autoconfig-test.tmp._homehub._autoconf.named-data.net

integ@d:~$ nfdc create udp://ns1.autoconfig-test.tmp._homehub._autoconf.named-data.net:6363

Do not confirm this issue on OSX 10.9, though with slightly different zone (but it shouldn't matter):

zone "test" in named.conf

[cawka@cawka-mac local (master)]$ cat var/named/test

Please test with the given zone name.
Hila believes the underscore in zone name matters.

I tried to reproduce the problem with bind in 14.04, but it always refused to load this zone.

I've added test record to real _homehub._autoconf.named-data.net. zone:

[cawka@cawka-mac ~]$ dig test._homehub._autoconf.named-data.net

On OSX 10.9, I don't see the problem

[cawka@cawka-mac ~]$ nfdc create udp://test._homehub._autoconf.named-data.net
Face creation succeeded: ControlParameters(FaceId: 9, Uri: udp4://1.1.1.1:6363, )

Ok. Finally was able to reproduce the problem, on Ubuntu 14.04

I'd like to reject this Bug because a hostname that contains underscore violates RFC 952, which says:

 1. A "name" (Net, Host, Gateway, or Domain name) is a text string up
 to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus
 sign (-), and period (.).

I agree to reject this. This is not NFD or even boost asio problem. This has something to do with Ubuntu's getaddrinfo. If you try to

nc test._homehub._autoconf.named-data.net. 1

or even ping this host, it should fail on Ubuntu.

I found a couple of topic on google about then, none of them helped to solve the problem, but they all suggest that it is something to do with the underscore that is suppose to be used only in mDNS.
