Par défaut need with BIND9

Hello,

I need setting up nameservers for my own domain. The IPs and
domains have been changed for privacy ;-)

I have a static IP on an ADSL line (i.e public IP 1.1.1.1).
I have a router that has a DMZ set up that is pointing to my deb box
(local IP 10.10.10.10)
I have a domain (mydomain.com) that I bought and I've set it up to point
to NS1.MYDOMAIN.COM at the public IP 1.1.1.1

I want to set up my deb box as a web/ftp/nameserver server with
MySQL/PHP on it.

So far, I've configured LAMP on it. I'm having problems with BIND (or so
I think). I've read all over that "DNS IS A SIMPLE BUT EASILY
MISCONFIGURED SYSTEM"

I've confirmed that NS1.MYDOMAIN.COM points to 1.1.1.1 as
http://ns1.mydomain.com produces my apache page

I'm using BIND9.

named.conf has this line at the bottom:

include "/etc/bind/named.conf.local";


my named.conf.local has this:

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

zone "10.10.10.in-addr.arpa" {
type master;
file "/etc/bind/10.10.10.rev";
};


my mydomain.db has this:

; BIND data file for mydomain.db
; /var/named/mydomain.db
;
$TTL 1h
@ SOA ns1.mydomain.com. root.mydomain.com. (
2007110805; Serial (date + two digit serial)
10800 ; Refresh (3 hours)
3600 ; Retry (1 hour)
86400 ; Expire (1 day)
60 ) ; Default TTL 1 min
NS ns1.mydomain.com.
MX mail.mydomain.com.
A 1.1.1.1

ns1 A 1.1.1.1
mail A 1.1.1.1
www A 1.1.1.1


It has been over 5 days, and www.mydomain.com still has not resolved to
1.1.1.1
What could be the problem?
DIG only produces a QUESTION SECTION but no answers,etc:

; <<>> DiG 9.3.4 <<>> mydomain.com

;; global options: printcmd

;; Got answer:

;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 36978

;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:

;mydomain.com. IN A

;; Query time: 1151 msec

;; SERVER: 66.51.205.100#53(66.51.205.100)

;; WHEN: Wed Nov 14 00:49:53 2007

;; MSG SIZE rcvd: 32


I've also done a zonecheck report, and right away it spits out "Unable
to find primary nameserver (SOA)"

Please ! Thank you very much!

If you are going to host authoritative DNS for mydomain.com. on a name
server host under the same domain, for example ns1.mydomain.com., then
you need to seed the process of finding your authoritative name server
via a glue A record at your domain registrar - this A record for
ns1.mydomain.com. gets pushed up to the com. TLD servers, so that
recursive resolvers around the Internet can find the correct name server
to ask, "where is mydomain.com.".

Thanks for the reply! I've investigated this at my domain registrar,
and ns1.mydomain.com did get pushed to the .com TLD servers (or root
servers)

Also, so that it'll be easier to troubleshoot, I will be using my actual
info (oh no!)

The domain is CD-EXPRESS.COM
NS1.CD-EXPRESS.COM already resolves to my static IP of 208.127.75.221

My domain registrar said that I need a primary and secondary server
assigned, so I created NS2.CD-EXPRESS.COM to point to the same IP
208.127.75.221

my bind settings is as follows (I've removed comments with a "//"):
********************** NAMED.CONF start
************************************************** *********
include "/etc/bind/named.conf.options";

zone "." {
type hint;
file "/etc/bind/db.root";
};

zone "localhost" {
type master;
file "/etc/bind/db.local";
};

zone "127.in-addr.arpa" {
type master;
file "/etc/bind/db.127";
};

zone "0.in-addr.arpa" {
type master;
file "/etc/bind/db.0";
};

zone "255.in-addr.arpa" {
type master;
file "/etc/bind/db.255";
};

include "/etc/bind/named.conf.local";

********************** NAMED.CONF end
************************************************** *********


**********************NAMED.CONF.OPTIONS
start********************************************* ********

directory "/var/cache/bind";

auth-nxdomain no; # conform to RFC1035
listen-on-v6 { any; };

allow-recursion { localnets; };

};

**********************NAMED.CONF.OPTIONS end
************************************************** ***



*****************************NAMED.CONF.LOCAL start
*************************************************
//
// Do any local configuration here
//

// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";

type master;
file "/etc/bind/cd-express.db";
};

zone "15.15.15.in-addr.arpa" {
type master;
file "/etc/bind/15.15.15.rev";
};
*****************************NAMED.CONF.LOCAL end
*************************************************

20 IN PTR dns.cd-express.com.
30 IN PTR mail.mycompany.com.

***************************** 15.15.15.REV end
*************************************************

*QUESTION:
Is the line comment for a bind configuration file, including the
includes, a "//" or ";" or ":"?? I've seen the semicolons and colons in
some bind configurations as well

I'll be happy to get ANY . Thanks a lot!
