behavior of k.root-servers.net

NSD
1

Hello NSD folks,

My name is Yasuhiro Orange Morishita at JPRS.

I found strange behavior on k.root-servers.net as described below.

I heard that k.root-servers.net is running NSD, so I think that the
cause of the strange behavior is the bug of NSD.

Now, I'm attending the IETF57 meeting at Vienna.

If possible, I want to talk with the code maintainer of NSD, and I
also want to inform the problem to the administrator of
k.root-servers.net.

Regards,

I'm correcting a typo and addendum to my previous email. Sorry.

  the correct answer.

I see the same problem with my own instance of nsd so, yes, this may
be a nsd problem.

Ok. I've opened a bug about this: <URL:http://www.nlnetlabs.nl/bugs/show_bug.cgi?id=59&gt;\. The attached patch fixes this problem for NSD 1.2.0 (and the just released 1.2.1 which does not include this patch).

Please apply this patch to NSD on K.root-servers.net.

Actually, k.root-servers.net is running NSD 1.0.2:

Hi Yasohiro,

Dave-san, thank you for your reply.

I found the new version of NSD (1.2.2) has been released. I think that
it is suitable to apply to k.root.
