2. Konfigurasi file dengan perintah :

   root@ubuntu:/ # Sudo pico /etc/default/isc-dhcp-server
   

   # Defaults for dhcp initscript
   # sourced by /etc/init.d/dhcp
   # installed at /etc/default/isc-dhcp-server by the maintainer scripts

   #
   # This is a POSIX shell fragment
   #

   # On what interfaces should the DHCP server (dhcpd) serve DHCP requests?
   # Separate multiple interfaces with spaces, e.g. “eth0 eth1?.
   INTERFACES=”eth0″

3. Tambahkan Tambah
Subnet
network
kita ke dalam file dhcpd.conf dengan perintah :

   root@ubuntu:/ # sudo pico /etc/dhcp/dhcpd.conf

   subnet 192.168.237.0 netmask 255.255.255.0 {

        range 192.168.237.10 192.168.237.20;

   option domain-name-servers 192.168.237.2;

   option domain-name “labmi.polinela.ac.id”;

       option routers 192.168.237.2;

       option broadcast-address 192.168.237.255;

       default-lease-time 600;

       max-lease-time 7200;

   }

4. Restart service DHCP dengan perintah

   root@ubuntu:/ # /etc/init.d/isc­dhcp­server
restart

   Stopping
ISC
DHCP
server:
dhcpd
failed!

   Starting
ISC
DHCP
server:
dhcpd

5. Gunakan perintah netstat untuk memantau aktifitas di dalam jaringan.

   root@ubuntu:/ # netstat -uap

   Active Internet connections (servers and established)

   Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

   udp 0 0 *:bootps *:* 1126/dhcpd
   

6. Ujicobakan dengan merubah konfigurasi pada client menjadi Obtain.

   

7. Lihat hasilnya (sesuaikan dengan computer masing-masing)

   

    

8. Log dhcp server yang aktif dapat dilihat dengan perintah

   root@ubuntu:/ # tail -f /var/log/syslog

   Nov 6 22:18:02 ubuntu dhcpd: DHCPREQUEST for 192.168.237.10 from 08:00:27:00:68:3a (abunabiha) via eth1

   Nov 6 22:18:02 ubuntu dhcpd: DHCPACK on 192.168.237.10 to 08:00:27:00:68:3a (abunabiha) via eth1

   Nov 6 22:23:02 ubuntu dhcpd: DHCPREQUEST for 192.168.237.10 from 08:00:27:00:68:3a (abunabiha) via eth1

9. Untuk menghentikan service dhcp gunakan perintah :

   root@ubuntu:/ #/etc/init.d/isc­dhcp­server
stop

   * Stopping ISC DHCP server dhcpd [ OK ]

    

10. Untuk menghidupkan service dhcp gunakan perintah:
