DHCP Server Pada Fedora

Posted on May 15, 2009 by 1100060884

A. Pengantar

DHCP Server adalah sebuah mesin yang melayani permintaan alamat IP maupun konfigurasi jaringan secara dinamis program ini dibuat oleh Ted Lemon yang bekerja untuk Vixie Labs, dengan DHCP Server ini anda tidak perlu lagi untuk mengkonfigurasikan jaringan pada sisi client, anda cukup mengkonfigurasikan DHCP Server anda maka konfigurasi alamat ip, gateway bahkan nameserver pada sisi client tidak perlu dilakukan lagi.

Layanan ini bisa juga diberikan kepada suatu komputer dengan kriteria tertentu, misalnya saja berdasarkan alamat MAC Address Network Card ataupunberdasarkan hostnamenya. Untuk dapat menggunakan DHCP Server maka anda harus mempunyai program yang dapat meminta layanan DHCP Server ini salah satunya adalah dhclient yang juga dibuat oleh Ted Lemon.

B. Instalasi

Karena sistem yang digunakan adalah Fedora, maka instalasinya sebagai berikut :

[root@NMS-Kuningan ~]#yum install dhcp

Pastikan semua file dibawah ini sudah di install :

[root@NMS-Kuningan ~]# rpm -qa | grep dhcp

libdhcp6client-1.0.14-1.fc9.i386
libdhcp-1.99.8-1.fc9.i386
dhcp-4.0.0-14.fc9.i386
dhcpv6-client-1.0.14-1.fc9.i386
libdhcp4client-4.0.0-14.fc9.i386

Untuk memeriksa apakah dhcp sudah jalan atau tidak maka gunakan perintah berikut :

[root@NMS-Kuningan ~]# service dhcpd restart
Shutting down dhcpd: [ OK ]
Starting dhcpd: [ OK ]

C. Konfigurasi

Konfigurasi dilakukan di file dhcpd.conf , untuk melakukan konfigurasi lakukan perintah di bawah ini :

[root@NMS-Kuningan ~]# vim /etc/dhcpd.conf

Hasilnya adalah :

# DHCP Server Configuration file.

# see /usr/share/doc/dhcp*/dhcpd.conf.sample

# see ‘man 5 dhcpd.conf’

# VLAN 232 (Server_Farm)

#ini adalah segmen dari DHCP server, ini harus didaftarkan dulu biar jalan kalau tidak didaftarkan, service dhcpd akan failed.

Untuk menjalankan dhcp secara otomatis apabila server di restart adalah dengan cara :

[root@NMS-Kuningan ~]# ntsysv

dhcpp

Beri tanda bintang pada dhcpd

Perlu diingat bahwa arti dari default-lease-time 600; adalah bahwa setiap 10 menit akan dilakukan konfirmasi dari server terhadap client.

D. Kesimpulan

Hal-hal yang perlu diingat adalah :

1. File konfigurasi disimpan di file dhcpd.conf

2. Setiap ada perubahan pada file dhcpd.conf maka lakukan restart pada dhcp dengan perintah :

[root@NMS-Kuningan ~]# service dhcpd restart
Shutting down dhcpd: [ OK ]
Starting dhcpd: [ OK ]
