Dear Friends,

I have problem with DNS configuration in ubuntu server 8.04 lts.

I want to configure zimbra mail server 6.0.16.

The scenario is described as below.

Steps:

1). First of all i have changed /etc/bind/named.conf. file with

forwarders {

};


2). Then restarted the DNS server.

sudo /etc/init.d/bind9 restart

it reflects no error in both steps.

3). Checked the /etc/resolv.conf file

nameserver xxx.xxx.xxx.xxx


4). Then configured BIND9 with my FQDN.

In /etc/bind/named.conf.local file

zone "******.com" {
type master;
file "/etc/bind/db.******.com";
};


5). Then created the template with this command.

sudo cp /etc/bind/db.local /etc/bind/db.example.com

6). Then edited the new zone file with below changes.

;
; BIND data file for mydomain.com
;
$TTL 604800
@ IN SOA mail.mydomain.com. admin.mydomain.com. (
6 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS mail
IN MX 10 mail
IN A xxx.xxx.xxx.xxx
mail IN A xxx.xxx.xxx.xxx


7). Then /etc/init.d/bind9 restart

8). Edited reverse zone file /etc/bind/named.conf.local with

zone "*.***.***.in-addr.arpa" {
type master;
notify no;
file "/etc/bind/db.192";
};


9). sudo cp /etc/bind/db.127 /etc/bind/db.192


10). created a PTR record in /etc/bind/db.192.


;
; BIND reverse data file for local loopback interface
;
$TTL 604800
@ IN SOA ns.******.com. root.******.com. (
3 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS ns.
10 IN PTR ns.******.com.

11). sudo /etc/init.d/bind9 restart


Then I have fired the dig command


dig @


But it reflects the error like

global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 6672


Any suggestion will be appreciated.
