running bind for dns

notolerance · 11-10-2004, 10:49 AM

Hello all,
I want to be able to run a primary and secondary name sever on a leased line for a friends company. I can configure all aspects on the servers for mysql/apache/php/ftp/bind etc. What I am confused about (let me tell you I have read to 2 weeks on this subject) is how to set up dns that a client can use to resolve my server through there registar.

For example:
I register my domain ‘abc123’.com with any regestar.

In my /etc/named.conf file I set up a ns1 and ns2 at my domain and point them to an ip address of the box in question.

What I’m missing here is how do I populate this sub-domain as ns1 and ns2 as a part of the domain abc123.com to all of the main dns servers?

Am I way off here?

You configure it on your local DNS server(s). Main DNS servers don't store all hosts in all subdomains. Just the right server to ask about that domain is stored.

I guess that is my question. as per my example if I own abc123.com can I just configure bind with ns1.abc123.com and ns2.backupabc123.com and then popluate? If so How?

here are some of my configurations/

Code:

;
; /ext/named/abc123.com 
;
$TTL    86400   
@       IN      SOA     ns.abc123.com. hostmaster.abc123.com. (
                                2001052800      ; serial, todays date + todays serial #
                                8H              ; refresh, seconds
                                2H              ; retry, seconds
                                1W              ; expire, seconds
                                1D )            ; minimum, seconds
        
               NS      ns.abc123.com.      ; Inet Address of name server
               NS      ns.backup123abc.com.  ; Inet address of backup server
        
               MX   10 mail.abc123.com.    ; Primary Mail Exchanger
        

ns              86400   A       100.200.0.212
                                HINFO   "a486/160/40M" "Linux 2.0"
        
mail            86400   A       100.200.0.212
                                HINFO   "a486/160/40M" "Linux 2.0"
        

ftp             86400   CNAME   ns
        
data            86400   CNAME   ns;

and then
dig @a.root-servers.net . ns > /etc/named/root.hints.db

I figured it out. My configuration was fine. I had to set up the the ns1-ns2 on seperate external ips and then point them top the regestar at dns entries.

Exactly

Then you can add hosts to teh configuration file (like ftp or mail in the example you provided).
