DNS service and files

[Smitty]

... let me understand this correctly...

If I register my new domain (i.e smittydomain.com), and I wish to operate my own authoritative nameserver for that same domain (i.e ns1.smittydomain.com), you're saying I can't do that (without dependence upon an already registered nameserver elsewhere)? My domain registrar has told me they can register my nameserver at the same time that I register my new domain as part of the single registration process for my new domain.

Do all registrar's not have the capability to register the nameservers for that same domain, if called upon to do so?

.. not wishing to get caught in the stumblings of which came first - the chicken or the egg.

.. in advance, thanks.

I recommend that you register a "technical" domain (a domain you use for technical purposes only), then create ns1.<technicaldomain> and ns2.<technicaldomain> as A records, and then use these name servers when you register other domains.

Hi All,

I have installed Cent OS 5 and ISP Config.

I log into ISP config it tells me bind dns = offline

I don't know what is wrong.

Domain is www.mad2.co.uk and have set up bind to use ns1.dnsmaster.net for www.mad2.co.uk IP for Nameserver is 212.84.167.18

And I am using my Static IP 84.45.211.25 for all other domains so in effect a loopback on itself. I have opened tcp/udp port 53 to the server but can't get any local domain like 1.mad2.co.uk to work.

If anyone can help would be much appreciated

Many Thanks

What's the output of

netstat -tap

? Any BIND errors in your log files?
Did you disable SELinux? Did you use the "Perfect Setup" for CentOS 5.0 to set up your server?
Which DNS server is the primary nameserver for your domain?

Any BIND errors in your log files? None that I know of
Did you disable SELinux? Yes the How to Forge Cent OS 5 32 bit Did you use the "Perfect Setup" for CentOS 5.0 to set up your server? Yes
Which DNS server is the primary nameserver for your domain?

Primary name server is ns1.dnsmaster.net My domain register is Skymarket so it's their dns server

[falko]

BIND is running, I can see it in the output ot netstat -tap.

So did you create slave zones then for mad2.co.uk on your ISPConfig server?

Can you run

dig @localhost mad2.co.uk

on your ISPConfig server? What's the output?

It's responding at least.

Two problems:
1)

Why do you use a local IP address? Nobody is then able to access your site from the outside...

2) I get this:

;; ANSWER SECTION:
mad2.co.uk.             43200   IN      A       84.45.211.25

which means that the primary DNS has stored another IP address for the domain than your own DNS server. This leads me to the assumption that you set up the mad2.co.uk zone as a master zone instead of a slave zone on your own nameserver...

Hmmm this could very well be true I set everything up using ISP config so how do I go about checking and changing to slave dns

Copy of named.conf

[root@server1 etc]# nano named.conf

GNU nano 1.3.12 File: named.conf


zone "1.mad2.co.uk" {
type master;
file "pri.1.mad2.co.uk";
};
zone "mad2.co.uk" {
type master;
file "pri.mad2.co.uk";
};


zone "ns1.mad2.co.uk" {
type slave;
file "sec.ns1.mad2.co.uk";
masters { 84.45.211.25; };
};
