facing problem in dns inverse query for IPv6
Hi
i'm facing problem in dns inverse query
for IPv6.
As per the test setup, i have my two
machines connected
in LAN...both the machines are Montavista
Linux 2.4.20_mvl31-pc_target.
One of them acting as a server &
another as client. In server machine
i have installed bind 9.2.4 which is
IPv6 aware. In client machine i have configured
/etc/resolv.conf like
nameserver
<link-local address of server machine>
Now my normal (standard) queries are
working fine like,
[root@localhost root]#
dig +qr ipv6.domain AAAA
; <<>> DiG
9.2.1 <<>> +qr ipv6.domain AAAA
;; global options: printcmd
;; Sending:
;; ->>HEADER<<-

;; flags: rd; QUERY: 1,
ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
;; QUESTION SECTION:
;ipv6.domain.
IN AAAA
;; Got answer:

86400 IN AAAA
fe80::210:b5ff:fea7:f057
;; AUTHORITY SECTION:
ipv6.domain.
86400 IN NS
ipv6.domain.
;; ADDITIONAL SECTION:
ipv6.domain.
86400 IN A
127.0.0.1
;; Query time: 5 msec

;; WHEN: Thu Sep 15 21:00:45

;; MSG SIZE rcvd:

But for inverse query I have configured
/etc/named.conf in server
zone "7.5.0.f.7.a.e.f.f.f.5.b.0.1.2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.e.f.ip6.arpa."
IN {
type master;
file "rev_file";
allow-query { my-net; };
};
and corresponding "rev_file"
in /var/named
$TTL 86400
@
IN SOA ipv6.domain. root.ipv6.domain.
(
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS ipv6.domain.
$ORIGIN 0.0.0.0.0.0.0.0.0.0.0.0.0.8.e.f.ip6.arpa.
7.5.0.f.7.a.e.f.f.f.5.b.0.1.2.0
IN PTR ipv6.domain.
but whenever i do inverse query always
i get SERVFAIL as status like
[root@localhost root]#
dig -x fe80::210:b5ff:fea7:f057
; <<>> DiG
9.2.1 <<>> -x fe80::210:b5ff:fea7:f057
;; global options: printcmd
;; Got answer:

but the same inverse query works fine
for IPv4.....
Actually i'm not finding what exactly
might be the reason...
is it because of the format which i
followed while
configuring /etc/named.conf & corresponding
/var/named/rev_file.....
or something else.....plz comment...
thanking u
