Thread: problem with sub-domain using bind9

i'm trying set sub-domain within private network , i'm using bind9 on authoritative dns server zone. believe working think there's issue uncovered in preliminary testing... sub-domain i'm trying control of still can't found.

output dig -x 127.0.0.1 on name server looks ok:

; <<>> dig 9.7.0-p1 <<>> -x 127.0.0.1
;; global options: +cmd
;; got answer:
;; ->>header<<- opcode: query, status: noerror, id: 18185
;; flags: qr aa rd ra; query: 1, answer: 1, authority: 1, additional: 2

;; question section:
;1.0.0.127.in-addr.arpa. in ptr

;; answer section:
1.0.0.127.in-addr.arpa. 604800 in ptr localhost.

;; authority section:
127.in-addr.arpa. 604800 in ns localhost.

;; additional section:
localhost. 604800 in 127.0.0.1
localhost. 604800 in aaaa ::1

;; query time: 0 msec
;; server: 192.168.2.99#53(192.168.2.99)
;; msg size rcvd: 121

when use dig query dns name server seems right me:

; <<>> dig 9.7.0-p1 <<>> ns.dev.example.org
;; global options: +cmd
;; got answer:
;; ->>header<<- opcode: query, status: noerror, id: 45149
;; flags: qr aa rd ra; query: 1, answer: 1, authority: 1, additional: 0

;; question section:
;ns.dev.example.org. in a

;; answer section:
ns.dev.example.org. 604800 in 192.168.2.99

;; authority section:
dev.example.org. 604800 in ns ns.dev.example.org.

;; query time: 0 msec
;; server: 192.168.2.99#53(192.168.2.99)
;; msg size rcvd: 73

however, when use dig query actual sub-domain there no answer section , see line:
;; flags: qr aa rd ra; query: 1, answer: 0, authority: 1, additional: 0

using dig query different name server host ns.dev.example.org turns same thing.

also, if use nslookup sub-domain returns:
** server can't find dev.example.org: nxdomain

zone file:

$ttl 604800
dev.example.org. in soa ns.dev.example.org. admin.dev.example.org. (
16 ; serial
604800 ; refresh - 7 days
86400 ; retry - 24 hours
2419200 ; expire - 28 days
604800 ) ; negative cache ttl
;
in ns ns.dev.example.org.
dev.example.org in 192.168.2.99
ns in 192.168.2.99
desktop in 192.168.2.74

i'm not expert on bind9, zone file doesn't right me. try this:

code:

  $ttl 604800 @ in soa dev.example.org. admin.dev.example.org. ( 17 ; serial 604800 ; refresh - 7 days 86400 ; retry - 24 hours 2419200 ; expire - 28 days 604800 ) ; negative cache ttl    in  192.168.2.99 ; @  in ns ns.dev.example.org. ns in 192.168.2.99 desktop in 192.168.2.74
