Setting Up DHCP Server FreeBSD 7

ekilas tentang DHCP : DHCP (Dynamic Host Configuration Protocol) adalah protokol yang berbasis arsitektur client/server yang dipakai untuk memudahkan pengalokasian alamat IP dalam satu jaringan. Sebuah jaringan lokal yang tidak menggunakan DHCP harus memberikan alamat IP kepada semua komputer secara manual. Jika DHCP dipasang di jaringan lokal, maka semua komputer yang tersambung di jaringan akan mendapatkan alamat IP secara otomatis dari server DHCP. Selain alamat IP, banyak parameter jaringan yang dapat diberikan oleh DHCP, seperti default gateway dan DNS server (wikipedia).OK… mulai yuks
Konfigurasi :
DHCP Interface : xl0
Subnet Mask : 255.255.255.0
Gateway : 192.168.0.200
Name Server : 192.168.0.200, 208.67.222.222, 208.67.220.220
Cek mesin :

Install DHCP Server :

Added group “dhcpd”.
Added user “dhcpd”.
****  To setup dhcpd, you may have to copy /usr/local/etc/dhcpd.conf.sample
to /usr/local/etc/dhcpd.conf for editing.
Edit dhcpd.conf :
[root@arema /home/arema]# nano /usr/local/etc/dhcpd.conf

Buat file leases :
[root@arema /home/arema]# touch /var/db/dhcpd.leases
Tambahkan di rc.conf :
[root@arema /home/arema]# nano /etc/rc.conf
dhcpd_enable=”YES”
dhcpd_ifaces=”xl0″
restart mesin……
lihat client yang aktif :
[root@arema /home/arema]# tail -f /var/db/dhcpd/dhcpd.leases
contoh hasilnya :
}
lease 192.168.0.25 {
starts 1 2009/11/09 01:07:32;
ends 1 2009/11/09 01:17:32;

next binding state free;
hardware ethernet 00:24:3a:0f:20:76;

client-hostname “eka”;
}
lease 192.168.0.29 {
starts 1 2009/11/09 01:09:06;
ends 1 2009/11/09 01:19:06;
