debian:/home/student# ping 10.252.1.1

2. Hapus dhcp3-server pada komputer, walaupun tidak ada tetap hapus aja untuk cari aman
dpkg -P dhcp3-server
3. Kemudian install kembali dhcp3-server
debian:/home/student# apt-get install dhcp3-server

4. konfigurasi dhcp server
vim /etc/dhcp3/dhcpd.conf
subnet 10.252.108.0 netmask 255.255.255.0{
range 10.252.108.50 10.252.108.250;
option domain-name-servers 202.154.187.2,202.154.187.3;
option domain-name"eepis-its.edu";
option routers 10.252.108.1;
option broadcast-address 10.252.108.255;}
5. restart dhcp
debian:/home/student# /etc/init.d/dhcp3-server restart
Stopping DHCP server: dhcpd3.
Starting DHCP server: dhcpd3.
6. setting dhcp pada client --> pada komputer client
dhclient
ket : device diisi dengan network device yang aktif pada client dengan cara ketik : mii-tool.
pilih eth yang linknya ok
cth : dhclient eth1
7. cek dhcp server leases
more /var/lib/dhcp/dhcpd.leases
8. edit file config dhcpd3
vim /etc/dhcp3/dhcpd.conf
subnet 10.252.108.0 netmask 255.255.255.0{
range 10.252.108.50 10.252.108.250;
option domain-name-servers 202.154.187.2,202.154.187.3;
option domain-name"eepis-its.edu";
option routers 10.252.108.1;
option broadcast-address 10.252.108.255;
host mycomp{
hardware ethernet 01:f0:4d:63:52:66;
fixed-address 10.252.108.255;
option domain-name-servers 202.154.187.2,202.154.187.3;
option domain-name"eepis-its.edu";
option broadcast-address 10.252.108.255;
}
}
9. uji coba pada client --> pada komputer client
dhclient eth1 atau eth0
