DHCP Server

1. Instalasi :

#apt-get install dhcp3-server

2. Setelah instalasi edit file dhcp.conf :

#nano /etc/dhcp3/dhcpd.conf

#

# Sample configuration file for ISC dhcpd for Debian

#

# $Id: dhcpd.conf,v 1.1.1.1 2002/05/21 00:07:44 peloy Exp $

#

 

# The ddns-updates-style parameter controls whether or not the server will

# attempt to do a DNS update when a lease is confirmed. We default to the

# behavior of the version 2 packages (‘none’, since DHCP v2 didn’t

# have support for DDNS.)

ddns-update-style none;

 

# option definitions common to all supported networks…

option domain-name “example.org”;

option domain-name-servers ns1.example.org, ns2.example.org;

 

default-lease-time 600;

max-lease-time 7200;

 

# If this DHCP server is the official DHCP server for the local

# network, the authoritative directive should be uncommented.

#authoritative;

 

# Use this to send dhcp log messages to a different log file (you also

# have to hack syslog.conf to complete the redirection).

log-facility local7;

 

# No service will be given on this subnet, but declaring it helps the 

# DHCP server to understand the network topology.

 

#subnet 10.152.187.0 netmask 255.255.255.0 {

#}

 

# This is a very basic subnet declaration.

 

#subnet 10.254.239.0 netmask 255.255.255.224 {

#  range 10.254.239.10 10.254.239.20;

#  option routers rtr-239-0-1.example.org, rtr-239-0-2.example.org;

#}

 

# This declaration allows BOOTP clients to get dynamic addresses,

# which we don’t really recommend.

 

#subnet 10.254.239.32 netmask 255.255.255.224 {

#  range dynamic-bootp 10.254.239.40 10.254.239.60;

#  option broadcast-address 10.254.239.31;

#  option routers rtr-239-32-1.example.org;

#}

 

# A slightly different configuration for an internal subnet.

  subnet 192.168.1.0 netmask 255.255.255.0 {

  range 192.168.1.2 192.168.1.10;

# option domain-name-servers ns1.internal.example.org;

# option domain-name “internal.example.org”;

  option routers 192.168.1.1;

  option broadcast-address 192.168.1.255;

  default-lease-time 600;

  max-lease-time 7200;

}

 

# Hosts which require special configuration options can be listed in

# host statements.   If no address is specified, the address will be

# allocated dynamically (if possible), but the host-specific information

# will still come from the host declaration.

 

#host passacaglia {

#  hardware ethernet 0:0:c0:5d:bd:95;

#  filename “vmunix.passacaglia”;

#  server-name “toccata.fugue.com”;

#}

 

# Fixed IP addresses can also be specified for hosts.   These addresses

# should not also be listed as being available for dynamic assignment.

# Hosts for which fixed IP addresses have been specified can boot using

# BOOTP or DHCP.   Hosts for which no fixed address is specified can only

# be booted with DHCP, unless there is an address range on the subnet

# to which a BOOTP client is connected which has the dynamic-bootp flag

# set.

#host fantasia {

#  hardware ethernet 08:00:07:26:c0:a5;

#  fixed-address fantasia.fugue.com;

#}

 

# You can declare a class of clients and then do address allocation

# based on that.   The example below shows a case where all clients

# in a certain class get addresses on the 10.17.224/24 subnet, and all

# other clients get addresses on the 10.0.29/24 subnet.

 

#class “foo” {

#  match if substring (option vendor-class-identifier, 0, 4) = “SUNW”;

#}

 

#shared-network 224-29 {

#  subnet 10.17.224.0 netmask 255.255.255.0 {

#    option routers rtr-224.example.org;

#  }

#  subnet 10.0.29.0 netmask 255.255.255.0 {

#    option routers rtr-29.example.org;

#  }

#  pool {

#    allow members of “foo”;

#    range 10.17.224.10 10.17.224.250;

#  }

#  pool {

#    deny members of “foo”;

#    range 10.0.29.10 10.0.29.230;

#  }

#}

 

Catatan :

Hilangkan tanda (#) pada file yang tertulis tebal.

3. Save file yang sudah edit.

4. Restart DHCP server :

#/etc/initd/dhcp3-server restart

 

5. Pengecekan :

– Pada computer server :

#ping 192.168.1.1

– Pada computer client :

   Harus mengubah pengelamatan IP secara Automatically :

Start > Control Panel > Network and Internet Connection > Network     Connection > Klik kanan pada icon computer. Pilih properties > pilih Internet Protocol (TCP/IP) > klik Properties. Ubah IP dan DNS menjadi automatically.

– Double klik icon computer pada toolbar bawah paling kanan > pilih support > klik repair. Secara otomatis IP akan keluar. 

– Untuk memastikan, ping IP server kita.

Start > Run > ketik ping 192.168.1.1

– Jika muncul jawaban reply, DHCP server telah berhasil.

 

6. Jika ingin mempunyai 2 IP DNS server, edit script dhcp.conf :

# option definitions common to all supported networks…

option domain-name “www.etha.com”;

option domain-name-servers 192.168.1.1, 208.67.222.222;

 

7. Restart DHCP server :

#/etc/initd/dhcp3-server restart

 

Pengecekan :

– Pada computer client :

Double klik icon LAN (double computers) pada toolbar > klik support > klik repair > klik finish > click detail, untuk mengetahui apakah settingan berhasil.

8. Dan jika ingin mempunyai IP yang diinginkan pada computer client, contoh 192.168.1.18. Edit script dhcp.conf  :

 

host fantasia {

  hardware ethernet 00:30:18:AC:OD:FD;

  fixed-address 192.168.1.18;

}

9. Restart DHCP server :

#/etc/initd/dhcp3-server restart

 

Pengecekan :

– Pada computer client :

Double klik icon LAN (double computers) pada toolbar > klik support > klik repair > klik finish. ^_^
