DHCP


 
Configurar a interface de rede

• Editar "vi /etc/network/interfaces":

iface eth0 inet static
        address 192.168.1.108
       netmask 255.255.255.0
       gateway 192.168.1.1

• Reboot na maquina ou reboot na interface.

• Editar "vi /etc/resolv.conf" (serverDNS):

nameserver 200.65.37.2

• Teste com um ping para fora da rede:

ping www.google.com.br

  Instalar o servidor DHCP:

apt-get install dhcp3-server

 Editar "vi /etc/dhcp3/dhcpd.conf":
                                                                                                                     
subnet 192.168.x.0 netmask 255.255.255.0 {
option domain-name-servers 200.135.37.65;               # Servidor DNS
option domain-name "redesX.edu.br";                            # Nome do domínio
option routers 192.168.1.1;                                            # Roteador padrão
option subnet-mask 255.255.255.0;                                # Máscar de rede
range dynamic-bootp 192.168.8.20 192.168.8.40;       # A faixa de endereços default-lease-time 21600;                                                # Tempo de aluguel
max-lease-time 43200;                                                    # Tempo máximo/aluguel

}

                                                                                                                      

   Reiniciar o servidor DHCP:

 service dhcp3-server restart

 OBS: Erros no arquivo de log "tail /var/log/syslog"

 Testes na maquina cliente:

•  Na maquina cliente, instalar cliente dhcp3

apt-get install dhcp3-cliente

•  Buscar novo ip: "dhclient eth0"
•  Largar novo ip: "dhclient -r eth0"
