The DNS [Domain Name System] is a key component of a network infrastructure. It allows you to use NAMES instead of IP addresses and technical garbage.
You can learn how it works through a simple Google request.
Here, I will present the installation of:
- DNS primary server (= DNS for domain smartcards.local) using BIND9
- Local domain (.local)
You can re-use all this content for a web-site or public domain. Just replace smartcards.local by mywebsite.com.
Contents
Setup
apt-get install bind9 dnsutils bind9-doc
Primary master
A DNS primary master is the main DNS for your local domain (ex: smartcards.local).
These are the steps to do:
- Set the external DNS to use by your server
- File: /etc/bind/named.conf.options
- Declare the new domain to manage
- File: /etc/bind/named.conf.local
- Create a dedicated configuration file for the new domain
- New file: /etc/bind/smartcards.local
- Adjust the reverse zone
- Rename and adjust file: /etc/bind/db.192
Set the external DNS
This is the list of DNS your server will use to populate its own cache.
The external DNS can either be your ISP's DNS or Google's servers.
!! Mind the order !! First DNS have a higher priority.
Edit configuration file:
vim /etc/bind/named.conf.options
Uncomment and adjust the file content
[...]
forwarders {
# Local gateway or router
172.16.50.1;
# Your ISP DNS IP’s
182.176.39.23;
182.176.18.13;
# Google's DNS
8.8.8.8
8.8.4.4
};
[...]
Declare the new domain
Edit configuration file:
vim /etc/bind/named.conf.local
Uncomment and adjust the file content
zone "smartcards.local" {
type master;
file "/etc/bind/smartcards.local";
};
Domain configuration file
Create the domain configuration file from a local template:
cp /etc/bind/db.local /etc/bind/smartcards.local
Edit configuration file:
vim /etc/bind/smartcards.local
Adjust the file content
;
; BIND data file for smartcards.local (you can use mywebsite.com)
;
$TTL 604800
@ IN SOA smartcards.local. root.smartcards.local. (
201406031132 ; Serial
; As the serial be changed everytime you edit this file
; it's recommended to use the pattern "yyyyMMddHHmm"
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
; Primary DNS server declaration
@ IN NS smartcard-gw.smartcards.local
@ IN A 172.16.50.2
;
; -- alternative -- To declare a server a specific domain only
;
;website.com IN NS smartcard-gw.website.com
;website.com IN A 172.16.50.2
IN A 192.168.1.10
; Make
@ IN A 192.168.1.10
@ IN AAAA ::1
ns IN A 192.168.1.10
Reverse zone file
Edit configuration file:
vim /etc/bind/named.conf.local
Uncomment and adjust the file content
