Modul DNS

DOMAIN NAME SERVER
DNS FOR BIND READHAT ENTERPRICE

SETTING DNS
# /etc/resolv.conf
- Name Server
- DNS
# /etc/host
- Host. Bind
- Bind . host
Langkah Setiing DNS
1. Cek Paket Instalasi BIND
#rpm –qa | grep bind*
Bindutils x.2.x.x
Bind-libs-x 2.4.x
Ypbind-x.x.2.x
Bin-chroot-x.2.4.x
Bind.utils-x.2.4.x
Bin-x.2.4.x
2. Backup File Named /etc/named.conf
Konfigurasi file /etc/named.conf
# vi /etc/named.conf
};
Zone “inix.com” in {
Type master;
File “inix.com.zone”;
};
Zone “1.168.192. in.addr.arpa” in {
File “0.169.192.in.addr.arpa”;
Allow-update { none; };
};
Include “/etc/rcdc.key”;

3. Buat pemetaan dari host ke IP ( forward.zone)
o Cek file localhost.zone
#cd /etc/var/named
#ls -l
o Lihat isi file localhost.zone
#cat /etc/var/named
o Lakukan pengkopian file localhost.zone menjadi forward.zone
#cp /var/named/localhost.zone ~/var/named/forward.zone
o Edit file forward.zone
# vi /etc/named/forward.zone
@ IN SOA server.polbeng.ac.id.~root@polbeng.ac.id (
42 ; serial (d.adam)
3H ; resfresh
15M ; retry
1W ; expire
1D) ; minimum
IN NS server..polbeng.ac.id.
Server IN A 192.168.1.1
www IN CNAME server.polbeng.ac.id.

 Simpan File forward.zone, tekan esc, :wq
 # service named reload
 #service named restart

4. Buat pemetaan dari IP ke host ke ( reverse.zone)
o Cek file domain.zone
# cd /etc/named
#ls -l
o Lihat isi file domain.zone
#cat /etc/var/named
o Lakukan pengkopian file domain.zone menjadi reverse.zone
#cp /var/named/domain.zone ~/var/named/reverse.zone
o Edit file reverse.zone
# vi /etc/named/reverse.zone
@ IN SOA server.polbeng.ac.id.~root@polbeng.ac.id (
42 ; serial (d.adam)
3H ; resfresh
15M ; retry
1W ; expire
1D) ; minimum
IN NS server..polbeng.ac.id.
1 IN PTR www.polbeng.ac.id.

 Simpan File forward.zone, tekan esc, :wq
 # service named reload
 #service named restart
o Copy file forward.zone dan reserve.zone ke /etc/var/named/chroot/var/named
# cp /etc/var/named/forward.zone~ /etc/var/named/chroot/var/named
o Lakukan pengecekan file
# vi /etc/var/named/chroot/var/named

5. Ubah file /etc/sysconfig/network
# /etc/sysconfig/network
NETWORK=yes
HOSTNAME=server
6. Ubah file /etc/resolv.conf
# vi /etc/resolv.conf
Search polbeng.ac.id
Domain polbeng.ac.id
Nameserver polbeng.ac.id
7. Ubah file /etc/host.conf
# vi /etc/host.conf
127.0.0.1 localhost.localdomain localhost
8. Ubah file ifcfg-eth0
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
IPADDR=192.168.1.1
NETMASK=255.255.255.0
NETWORK=192.168.1.0
BROADCAST=192.168.1.255
HWADDR=00:00:00:00:00  mac ethernet
ONBOARD=yes
TYPE=Ethernet
# service network restart

9. Uji DNS apakah berhasil atau tidak
o #nslookup www.polbeng.ac.id
o #nslookup server
o Ping 192.168.1.1
o Ifconfig –a (lihat konfigurasinya)
