Reverse DNS resolution issue

[yumbelie]

Hi. I've got my DNS server almost working, problem is it currently isn't working on reverse DNS requests. Forward are fine, e.g.:

> ns1.mynameserver.com
Server: ns1.mynameserver.com
Address: 0.0.0.0

Name: ns1.mynameserver.com
Address: 17.18.19.1

>

But reverses fail, if I put in 17.18.19.1 I get:

> 17.18.19.1
Server: ns1.mynameserver.com
Address: 0.0.0.0

*** ns1.mynameserver.com can't find 17.18.19.1: Non-existent host/domain
>

Now, I've configured named.conf (it's freeBSD I'm using), the two bits of interest are configured as follows:

// Forward DNS for domain

zone "mynameserver.com" {
type master;
file "mynameserver.com";
};

// Reverse DNS for domain

zone "19.18.17.in-addr.arpa" {
type master;
file "reverse-mynameserver.com";
};

The two files: mynameserver.com & reverse-mynameserver.com are configured as follows:

mynameserver.com ->
-----------------------

; Domain Name Setup
$TTL 604800
mynameserver.com. IN SOA ns1.mynameserver.com. root.mynameserver.com. (
2003061201 ; Serial
10800 ; Refresh 10800 secs
7200 ; Retry
86400 ) ; Expire (100 Days)
; DNS Servers
IN NS ns1.mynameserver.com.
; Machine Names
localhost IN A 127.0.0.1
ns1 IN A 17.18.19.1
@ IN A 17.18.19.1
testmachine IN A 17.18.19.118

; Aliases
moonshine IN CNAME @

reverse-mynameserver.com
---------------------------

; Domain Name Setup
$TTL 604800
@ IN SOA ns1.mynameserver.com. root.mynameserver.com. (
2003061201 ; Serial
10800 ; Refresh 10800 secs
7200 ; Retry
86400 ) ; Expire (1 Days)
; Reverse Lookup
IN NS ns1.mynameserver.com.
1 IN PTR ns1.mynameserver.com.

I cannot see what the problem is, I'm sure it should be correct - but perhaps one of you experts could shed some light? Incidentally, I am doing the nslookups on my nameserver locally, so I know the fault lies locally, not elsewhere.

Resolved it, I had incorrectly specified the reversed zone IP of the reverse lookup file in named.conf. Always worth checking that.
