Hello,
Firstly thanks for any helps I have got on this list for our DNS setup in
university environment.
Now I meet another problem, please see this dig:
# dig smartip.gduf.edu.cn ns +short
dtone1.gduf.edu.cn.
That means smartip.gduf.edu.cn is a zone whose NS is dtone1.gduf.edu.cn.
I have setuped the www ARR in this zone, ie,
# dig www.smartip.gduf.edu.cn +short
121.8.235.88
That seems correct, and www.smartip.gduf.edu.cn should be responsed by
dtone1.gduf.edu.cn.
OK after that I dig with trace:
# dig www.smartip.gduf.edu.cn +trace
; <<>> DiG 9.5.0-P2 <<>> www.smartip.gduf.edu.cn +trace

Please see above info, www.smartip.gduf.edu.cn is now responsed by
gduf.edu.cn's auth-DNS directly (dns.gduf.edu.cn), not by dtone1.gduf.edu.cn
(the child zone's dns). But what I want is that it should be answered by the
dns of the child zone.
Why this happens and how to fixup it?
Please help, thank you.
Regards,
Wah.
