[nsd-users] strange behavior of nsd

[Андрей Скопенко]

Hello,

please explain me, how can be that situation:

$ dig axfr @someserver.domain2.com domain1.com | grep user1.domain1.com
user1.domain1.com.     300     IN      NS      ns1.domain2.com.
user1.domain1.com.     300     IN      NS      ns2.domain2.com.
user1.domain1.com.     300     IN      NS      ns3.domain2.com.
user1.domain1.com.     300     IN      NS      ns4.domain2.com.

but if i try 

$ dig ns @someserver.domain2.com user1.domain1.com
                                                            
; <<>> DiG 9.9.4-P1 <<>> ns @bill1.corp.domain2.com user1.domain1.com

i mean no answer, only authority section. How it can be?

nsd.conf section:
zone:
        name: "domain1.com"
        zonefile: "./domain1.com.db"
        provide-xfr: ::1 NOKEY
        provide-xfr: 127.0.0.1 NOKEY
        provide-xfr: someserver.domain2.com NOKEY


NSD 4.0.3


Thank you!
