Installer DNS Server
Install DNS server by download and install the package
apt-get install bind9
Configure DNS (Bind9)
First we will edit these 3 files.
- /etc/bind/named.conf.local
- /etc/bind/named.conf.options
- /etc/resolvconf/resolv.conf.d/base
Second we will create these 2 files.
- /etc/bind/zones/dka.local.db
- /etc/bind/zones/rev.0.0.10.in-addr.arpa
First step: add domain zone – dka.local
Enter the named.conf.local file
nano /etc/bind/named.conf.local
Add the entire to the file
# Our Domain zone
zone "dka.local." {
type master;
file "/etc/bind/zones/dka.local.db";
};
# For reverse DNS
zone "0.0.10.in-addr.arpa" {
type master;
file "/etc/bind/zones/rev.0.0.10.in-addr.arpa.db";
};
Secund step: Add the DNS servers from your ISP
Enter the named.conf.options file
nano /etc/bind/named.conf.options
Delete or comment the following
dnssec-validation auto;
auth-nxdomain no; # conform to RFC1035
listen-on-v6 { any; };
};
Add the following to the bottom of the file
forwarders {
172.16.4.66;
};
auth-nxdomain no; # conform to RFC1035
listen-on-v6 { any; };
listen-on { any; };
allow-query { 127.0.0.1; 172.16.4.66/24; 10.0.0.0/24;};
};
- NOTE: Be aware of which IP segment you are in. 172.16.4.66 = Hovedforløb 172.16.2.50,172.16.2.51 = Grundforløb
Third step: Modify the resolv.conf file
Enter the resolv.conf.d/base file
nano /etc/resolvconf/resolv.conf.d/base
Add the following lines
nameserver 10.0.0.1
domain dka.local
search dka.local
Fourth step: Define zones
First make the directory /etc/bind/zones
mkdir /etc/bind/zones
Second make the file dka.local.db
nano /etc/bind/zones/dka.local.db
Add the following text to the newly created file
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA ns.dka.local. root.dka.local. (
8 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS ns.dka.local.
ns IN A 10.0.0.1
ubuntu IN A 10.0.0.21
- The TTL or time to live is set for 3 days
- The ns.mydomain.com nameserver is defined
- Ubuntudesktop, pc and gateway are entered as an A record
- An alias of www is assigned to ubuntudesktop using CNAME
Step five: Create a “rev.0.0.10.in-addr.arpa” file for reverse lookup
nano /tec/bind/zones/rev.0.0.10.in-addr.arpa
$TTL 3D
@ IN SOA ns.dka.local. admin.dka.local. (
2007062001
28800
604800
604800
86400
)
IN NS ns.dka.local.
2 IN PTR ubuntu.dka.local
Step seks: Test vores nye domæne og DNS entries
Dig
$ dig dka.local
Nslookup
nslookup ns
