Untuk mengkonfigurasinya, dibutuhkan priveledge tertinggi, yaitu root.
#rpm -qa | grep dhcp
dhcpv6_client-0.10-13
dhcp-3.0.2-12
setelah terinstall, DHCP server memberikan contoh konfigurasi dhcpd.conf, filenya dapat kita liat dan kopi di /usr/share/doc/dhcp-3.0.2/dhcpd.conf.sample
berikut adalah contoh script dhcpd.conf:
ddns-update-style interim;
ignore client-updates;
#definisi subnet
subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
option domain-name”jakarta”;
option domain-name-servers 192.168.1.3;
# ini buat tamu , jadi mereka tinggal colok kabel aja
range dynamic-bootp 192.168.1.30 192.168.1.35;
default-lease-time 21600;
max-lease-time 43200;
#kalo yang ini buat komputer-komputer yang ada di kantor, jadi walaupun di pindah-pindah IP nya tetep

nah setelah konfigurasi selesai, aktifkan daemon dhcp
# /etc/init.d/dhcpd start
Memulai dhcpd: [ OK ]
Untuk Melihat, apakah konfigurasi kita berjasil atau tidak, dhcpd mencatat list client yang mendapat reservasi IP dari server, filenya bisa kita lihat di :
/var/lib/dhcp/dhcpd.leases
berikut contoh isi filenya :
[root@b6-uninet-personal-106-142 ~]# more /var/lib/dhcp/dhcpd.leases
# All times in this file are in UTC (GMT), not your local timezone. This is
# not a bug, so please don’t ask about it. There is no portable way to
# store leases in the local timezone, so please don’t request this as a
# feature. If this is inconvenient or confusing to you, we sincerely
# apologize. Seriously, though - don’t ask.
# The format of this file is documented in the dhcpd.leases(5) manual page.
# This lease file was written by isc-dhcp-V3.0.2
