PERSIAPAN
Klik Kanan layar desktop
Klik New Terminal

Konfigurasi IP Addres
Ketikkan:
pico /etc/network/interfaces ¿ (enter)


pastikan isinya seperti di bawah ini:

# This file describes the network interfaces available on your system

# and how to activate them. For more information, see interfaces(5).

# The loopback network interface

auto lo

Iface lo inet loopback

auto eth0


iface eth0 inet static

address 200.100.50.20
netmask 255.255.255.240
network 200.100.50.0


broadcast 200.100.50.255

Simpan dan keluar:
Tekan Ctrl+O, Enter, kemudian Ctrl+X




Edit file hosts
Ketikkan:
pico /etc/hosts ¿ (enter)




Pastikan isinya:
127.0.0.1 localhosts
200.100.50.20 smkn2tkl.sch.id server


# the following lines are desirable for IpV6 capable hosts




Simpan dan keluar:
Tekan Ctrl+O, Enter, kemudian Ctrl+X




Edit File Resolv.conf
Ketikkan:
pico /etc/resolv.conf ¿ (enter)




Pastikan Isinya:
domain ns.smkn2tkl.sch.id.

b). Edit file konfigurasi DHCP Server :


pico /etc/dhcp3/dhcpd.conf ¿ (enter)


Hasilnya kurang lebih:


#


# Sample configuration file for ISC dhcpd for Debian


#


# $Id: dhcpd.conf,v 1.1.1.1 2002/05/21 00:07:44 peloy Exp $


#


# The ddns-updates-style parameter controls whether or not the server will


# attempt to do a DNS update when a lease is confirmed. We default to the


# behavior of the version 2 packages (‘none’, since DHCP v2 didn’t


# have support for DDNS.)


ddns-update-style none;


# option definitions common to all supported networks…

# If this DHCP server is the official DHCP server for the local


# network, the authoritative directive should be uncommented.

# have to hack syslog.conf to complete the redirection).

# DHCP server to understand the network topology.

# which we don’t really recommend.

# range dynamic-bootp 10.254.239.40 10.254.239.60;


# option broadcast-address 10.254.239.31;

# A slightly different configuration for an internal subnet.


subnet 200.100.50.0 netmask 255.255.255.240 {

}



# Hosts which require special configuration options can be listed in


# host statements. If no address is specified, the address will be


# allocated dynamically (if possible), but the host-specific information


# will still come from the host declaration.

#}


# Fixed IP addresses can also be specified for hosts. These addresses


# should not also be listed as being available for dynamic assignment.


# Hosts for which fixed IP addresses have been specified can boot using


# BOOTP or DHCP. Hosts for which no fixed address is specified can only


# be booted with DHCP, unless there is an address range on the subnet


# to which a BOOTP client is connected which has the dynamic-bootp flag


# set.

}


# You can declare a class of clients and then do address allocation


# based on that. The example below shows a case where all clients

Simpan dan keluar:

Restart DHCP server
Ketikkan:
/etc/init.d/dhcp3-server restart

3. Installasi DNS Server



Menginstall Paket DNS


apt-get install bind9


Tambahkan scripts pada file /etc/bind/named.conf untuk membuat zone forward dan zone reverse


pico /etc/bind/named.conf






Ketikkan scripts dibawah ini pada baris terbawah.






zone "smkn2tkl.sch.id" {
type master;
file "db.smk";
};




zone "50.100.200.in-addr.arpa" {
type master;
file "db.ip";
};

Simpan dan keluar:

Mengedit file db.ip
Ketikkan :
pico /etc/bind/db.127 Enter

Pastikan Hasilnya:
$TTL 86400
@ IN SOA ns.smkn2tkl.sch.id. root.smkn2tkl.sch.id. (


1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum


@ IN NS ns.smkn2tkl.sch.id.
1 IN PTR ns.smkn2tkl.sch.id.
;
2 IN PTR www.smkn2tkl.sch.id.
2 IN PTR tkj.smkn2tkl.sch.id.




Simpan dengan nama db.ip dan keluar:

Mengedit file db.local
Ketikkan :
pico /etc/bind/db.local Enter

Pastikan Isinya:
$TTL 86400
@ 1D IN SOA ns.smkn2tkl.sch.id. root.smkn2tkl.sch.id. (


42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum


1D IN NS ns.smkn2tkl.sch.id.
ns 1D IN A 200.100.50.20
;
smkn2tkl.sch.id. IN A 200.100.50.20
www IN A 200.100.50.25
tkj.smkn2tkl.sch.id. IN A 200.100.50.25


Simpan dengan nama file db.smk dan keluar:

Edit File Resolv.conf
Ketikkan:
pico /etc/resolv.conf
Pastikan Isinya:
domain ns.smkn2tkl.sch.id.
search smkn2tkl.sch.id
nameserver 200.100.50.20

Simpan dan keluar:
Menjalankan Server DNS
Ketikkan:
/etc/init.d/bind9 restart
Hasilnya:
[root@smkn2tkl root]# service named restart
Stopping named:
named: already running[root@smkn2tkl root]#

Mengecek keberhasilan pembuatan Server DNS
├śMengecek dengan menggunakan nslookup :
Ketikkan:
nslookup -sil 200.100.50



Hasilnya:
Server: 192.168.1.1
Address: 192.168.1.1#53
1.1.168.192.in-addr.arpa name = smkn2tkl.net.

├śMengecek port 53 apakah sudah terbuka :

Ketikkan:
nmap 192.168.1.1

Hasilnya:
Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Interesting ports on server.smkn2tkl.net (192.168.1.1):
(The 1597 ports scanned but not shown below are in state: closed)
Port State Service
22/tcp open ssh
53/tcp open domain
111/tcp open sunrpc
6000/tcp open X11

Nmap run completed -- 1 IP address (1 host up) scanned in 3 seconds

├śMelakukan test ping :

Ketikkan:
ping smkn2tkl.net

Jika muncul pesan reply seperti berikut, saya ucapkan selamat karena Anda telah berhasil membuat Server DNS. Unuk menghentikan proses PING tekan Ctrl+C

PEMBUATAN DNS SERVER JUGA SUDAH SELESAI “bozzzzzzzz”
