DNS server
Install a DNS server and configure a local DNS record.
Install
sudo apt-get install bind9
Configure zone
Add domain 'mydomain.com':
sudo gedit /etc/bind/named.conf.local
zone "mydomain.com" {
type master;
file "/etc/bind/db.mydomain.com";
};
Configure this file to use the provider's DNS server:
sudo gedit /etc/bind/named.conf.options
...
forwarders {
88.159.1.200;
88.159.1.201;
};
...
Define the zones, use '/etc/bind/db.local' as a template:
- ns = DNS Server name
- mydomain.com = domain name
- increment the Serial Number with each change
sudo cp /etc/bind/db.local /etc/bind/db.mydomain.com sudo gedit /etc/bind/db.mydomain.com
$TTL 604800 ; time to live
@ IN SOA ns.mydomain.com. admin-email.mydomain.com. (
2 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS ns.mydomain.com.
@ IN A 192.168.1.10
@ IN AAAA ::1
ns IN A 192.168.1.10
Configure reverse zone
A Reverse zone allows DNS to resolve an address to a name. Note the reversed IP address sequence '1.168.192' with the last octet missing.
sudo gedit /etc/bind/named.conf.local
Add the following:
...
zone "1.168.192.in-addr.arpa" {
type master;
file "/etc/bind/rv.192";
};
Create the reverse zone file, use '/etc/bind/db.127' as a template:
sudo cp /etc/bind/db.127 /etc/bind/rv.192 sudo gedit /etc/bind/rv.192
$TTL 604800 ; time to live @ IN SOA ns.mydomain.com. root.mydomain.com. ( 1 ; Serial 604800 ; Refresh 86400 ; Retry 2419200 ; Expire 604800 ) ; Negative Cache TTL ; @ IN NS ns. 10 IN PTR ns.mydomain.com.
Configure nameserver
Modify the resolv.conf to point to our DNS server, also see 'Configure fixed IP address' otherwise this file will be overwritten by the networkmanager:
sudo gedit /etc/resolv.conf
search mydomain.com. nameserver 192.168.1.10
Hostname
Configure the hostname:
sudo gedit /etc/hostname
mydomain.com
sudo gedit /etc/hosts
127.0.1.1 mydomain.com mydomain
hostname --fqdn
Restart and test
Restart Bind:
sudo /etc/init.d/bind9 restart
Test our new domain and DNS entries:
dig mydomain.com @dnsserver
dig mydomain.com
... ;; ANSWER SECTION: mydomain.com. 604800 IN A 192.168.1.10 ...
Router settings
If you want your local network to use your DNS you need to configure your router to hand out your server as primary DNS. Make sure you can configure a secondary DNS and that it is available. When your server is down the secondary DNS will be used.
