DNS SERVER
(DOMAIN NAME SYSTEM)
Fungsi:
-
Merubah Hostname menjadi IP dan IP menjadi Hostname
Langkah Membuat DNS
-
Setting IP DNS Server
#vim /etc/network/interfaces
iface eth0 inet static
address 192.168.2.44
netmask 255.255.255.128
broadcast 192.168.2.63
network 192.168.2.0
gateway 192.168.2.1
esc:wq
#/etc/init.d/networking restart

Install bind9
#apt-get install bind9

Melakukan Konfigurasi
Membuat Zone
#vim /etc/bind/named.conf
// This is the primary configuration file for the BIND DNS server named.
//
// Please read /usr/share/doc/bind9/README.Debian.gz for information on the
// structure of BIND configuration files in Debian, *BEFORE* you customize
// this configuration file.
//
// If you are just adding zones, please do that in /etc/bind/named.conf.local
include “/etc/bind/named.conf.options”;
// prime the server with knowledge of the root servers
zone “.” {
type hint;
file “/etc/bind/db.root”;
};
// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912
zone “localhost” {
type master;
file “/etc/bind/db.local”;
};
zone “127.in-addr.arpa” {
type master;
file “/etc/bind/db.127″;
};
zone “0.in-addr.arpa” {
type master;
file “/etc/bind/db.0″;
};
zone “255.in-addr.arpa” {
type master;
file “/etc/bind/db.255″;
};
zone “stm.com” {
type master;
file “/etc/bind/db.stm”;
};
zone “2.168.192.in-addr.arpa” {
type master;
file “/etc/bind/rev.stm”;
};
// zone “com” { type delegation-only; };
// zone “net” { type delegation-only; };
// From the release notes:
// Because many of our users are uncomfortable receiving undelegated answers
// from root or top level domains, other than a few for whom that behaviour
// has been trusted and expected for quite some length of time, we have now
// introduced the “root-delegations-only” feature which applies delegation-only
// logic to all top level domains, and to the root domain. An exception list
// should be specified, including “MUSEUM” and “DE”, and any other top level
// domains from whom undelegated responses are expected and trusted.
// root-delegation-only exclude { “DE”; “MUSEUM”; };
