DHCP une adresse IP automatique

Pour que les machines de notre petit réseau obtiennent une adr ip automatiquement on va utiliser du dhcp donc on installe dhcpd3 serveur et on configure dans le fichier
/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 $

#

# option definitions common to all supported networks...

option domain-name "labo.org";

option domain-name-servers ns1.labo.org, ns2.labo.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.



# This is a very basic subnet declaration.

subnet 10.0.0.0 netmask 255.255.255.0 {

  range 10.0.0.10 10.0.0.20;
