Hi,
BIND 8.3 on tru64.
I thought my DNS was working fine until I got a mail rejection because my revdns was
failing. True enough most server's can't resolve any of my ips but can work with the
host names. What is strange is that nslookup seems to says its working while dig says
my in-addr.arpa is non-existent.
EG:
>nslookup 194.200.237.129
Server: localhost
Address: 127.0.0.1
Name: helios.sciencephoto.co.uk
Address: 194.200.237.129
>dig 194.200.237.129
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 2
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0
I have pawed through my config and I can't see an error - althought there my be one
somewhere - so I am lost.
Debug suggests all is well with the revdns:
db_load(hosts.rev, 237.200.194.in-addr.arpa, 5, Nil, Normal)
d='237.200.194.in-addr.arpa', c=1, t=6, ttl=10800, data='helios.sciencephoto.co.uk.'
d='237.200.194.in-addr.arpa', c=1, t=2, ttl=10800, data='helios.sciencephoto.co.uk.'
so I guess the config file is okay. The zone file looks fine too.
$TTL 3h

Does anyone have any idea what else I can try. I have exhusted my toolset on this and
haven't got a clue what to try next.
Thanx.
Dp.
