Buatlah DNS Server (Primary dan Secondary) untuk domain :
inilab.net (194.162.105.100/26).
penyelesaian
DNS SERVER (PRIMARY)
1. Setup IP Adress server DNS ( studi
kasus domain \\\"inilab.net\\\" (194.162.105.100/26).
IP Server adalah \\\"194.162.105.101\\\"
# ifconfig eth2 194.162.105.101 netmask 255.255.255.192
broadcast 194.168.105.191
2. Ubah file /etc/named.conf
# pico /etc/named.conf
options {
directory
\\\"/var/named\\\";
};
zone
\\\".\\\" IN {
type
master;
file
\\\"named.ca\\\";
};
zone
\\\"localhost\\\" IN {
type
master;
file
\\\"localhost.zone\\\";
};
zone
\\\"0.0.191.in-addr.arpa\\\" IN {
type
master;
file
\\\"named.local\\\";
};
zone
\\\"inilab.net\\\" IN {
type
master;
file
\\\"inilab.zone\\\";
};
zone \\\"194.162.105.101.in-addr.arpa\\\"
IN {
type
master;
file
\\\"inilab.local\\\";
};
2.1. Membuat salinan semua file dari
/var/named/caching-example/ ke /var/named/
# cp /var/named/caching-example/* /var/named/
3. Ubah file
/var/named/localhost.zone
# pico
/var/named/localhost.zone
$TTL 86400
$ORIGIN localhost.
@ IN SOA localhost.
root.localhost. (
2011050900 ; Serial
1200 ; refresh
600 ; retry
604800 ; expiry
86400
) ; minimum
IN
NS localhost.
IN A 127.0.0.1
4. Ubah file /var/named/named.local
# pico /var/named/named.local
$TTL 86400
$ORIGIN 0.0.191.in-addr.arpa.
@ IN SOA localhost.
root.localhost. (
2011050900 ; Serial
1200 ; refresh
600 ; retry
604800 ; expiry
86400
) ; minimum
IN NS localhost.
1 IN PTR localhost.
5. Salin file
/var/named/localhost.zone menjadi /var/named/inilab.zone
# cp /var/named/localhost.zone /var/named/inilab.zone
6. Salin file /var/named/named.local
menjadi /var/named/inilab.local
# cp /var/named/named.local /var/named/inilab.local
7. Ubah file /var/named/inilab.zone :
# pico /var/named/inilab.zone
$TTL 86400
$ORIGIN inilab.net.
@ IN SOA inilab.net. root.inilab.net. (
2011050900 ; Serial
1200 ; refresh
600 ; retry
604800 ; expiry
86400
) ; minimum

149 IN PTR pc-19.inilab.net.
150 IN PTR pc-20.inilab.net.
110 IN PTR www.inilab.net.
120 IN PTR ftp.inilab.net.
130 IN PTR mail.inilab.net.
101 IN PTR ns1.inilab.net.
9. Test konfigurasi....
# /usr/sbin/named -g -c /etc/named.conf
10. Bila tidak muncul error, start
DNS
# /usr/sbin/named -c
/etc/named.conf
11. Test data DNS, dengan menggunakan
\\\"dig\\\"
# dig www.inilab.net.
DNS SERVER (SECONDARY)
1. Ubah file /etc/named.conf
# pico
/etc/named.conf
option {
directory
\"/var/named\";
};
zone
\".\" IN {
type
master;
file
\"named.ca\";
};
zone
\"localhost\" IN {
type
master;
file
\"localhost.zone\";
};
zone
\"0.0.127.in-addr.arpa\" IN {
type
master;
file
\"named.local\";
};
zone \"inilab.net\"
IN {
type
slave;
file
\"inilab-back.zone\";
masters { 194.162.105.101; };
};
zone
\"1.194.162.in-addr.arpa\" IN {
type
slave;
file
\"inilab-back.local\";
masters
{ 194.162.105.101; };
};
2. Start DNS secondary..
command :
# /usr/sbin/named
-c /etc/named.conf
semoga bermanfaat.
