This post will cover the setup of a bind server within the local network. It will resolve my.homezone locally on the bind server and forward all other requests to the google dns servers.
network = 192.168.1.0/24 bind server ip = 192.168.1.4 webserver ip = 192.168.1.5 local domain : my.homezone
Bind Installation
$ sudo apt-get update [ENTER]
$ sudo apt-get install bind9 bind9utils bind9-doc [ENTER]
named.conf.options
$ sudo vi /etc/bind/named.conf.options [ENTER]
Now we will define the clients allowed to query the bind server, to do so add the following (1st line).
acl trusted{
localhost;
192.168.1.0/24;
}
Now we have to define the forwarders within the options configuration.
forwarders{
192.168.1.4;
8.8.8.8;
8.8.4.4;
}
recursion yes;
allow-query {trusted;};
allow-recursion {trusted;};
listen-on {192.168.1.4;};
allow-transfer {none;};
save the file
now we check the config
$ named-checkconf [ENTER]
In case there’s no errors we can proceed.
Our zonefile “my.homezone”
$ sudo vi /etc/bind/named.conf.local [ENTER]
add the zone as followed
zone "my.homezone" {
type "master";
file "/etc/bind/zones/my.homezone";
}
Now we have to create the zonefile :
$ cd /etc/bind/zones [ENTER]
$ sudo cp ../db.local ./my.homezone [ENTER]
$ sudo vi my.homezone [ENTER]
Your file shall look similiar to this one :
@ IN SOA ns1.my.homezone. hostmaster.my.homezone. (
5 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
; Name servers
my.homezone. IN NS ns1.my.homezone.
ns1.my.homezone. IN A 192.168.1.4
; Other A records
; Web Server
www.my.homezone. IN A 192.168.1.5Does the webserver resolve
$ host www.my.homezone [ENTER]
should return
www.my.homezone has adress 192.168.1.5
resolv.conf
Finally we have to make sure it also works on reboot. Ubuntu tends to overwrite /etc/resolv.conf. We need to install resolvconf to prevent the system from overwriting the configuration on boot.
$ sudo apt-get install resolvconf$ sudo vi /etc/resolvconf/resolv.conf.d/headadd the following entries to the file
nameserver 192.168.1.4 search my.homezone
Check our settings
$ named-checkconf [ENTER]
$ named-checkzone my.homezone /etc/bind/zones/my.homezone
Now reboot and check if server resolves internal zone after boot.
In case there’s no errors you have successfully setup a bind server with your own domain. Congratulations.
