Configuração

Antes de alterar a configuração, a interface de rede deve ser parada:

root@rapsberrypi:~# ifdown eth0

A configuração das interfaces de rede é guardada no ficheiro /etc/network/interfaces:

root@rapsberrypi:~# cp /etc/network/interfaces /etc/network/interfaces.original

root@rapsberrypi:~# nano /etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
# allow-hotplug eth0
# iface eth0 inet dhcp

# Static IP address
auto eth0
iface eth0 inet static
        address 192.168.0.100
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        gateway 192.168.0.1
        dns-search rthomaz.local
        dns-nameservers 192.168.0.101

É necessário também indicar qual o endereço do servidor DNS. Nesta configuração, o servidor DNS funciona no modem/router ADSL ou cabo, pelo que o parâmetro nameserver deve ter o valor 192.168.0.1, no ficheiro /etc/resolv.conf:

root@rapsberrypi:~# cp /etc/resolv.conf /etc/resolv.conf.original

root@rapsberrypi:~# nano /etc/resolv.conf

domain rthomaz.local
search rthomaz.local
nameserver 192.168.0.100

Reiniciar a interface de rede para ativar a nova configuração:

root@server:~# ifup eth0

Verificação

O comando ifconfig fornece informação detalhada sobre a configuração das interfaces de rede. A configuração da interface eth0 deve exibir agora os parâmetros previamente definidos:

root@server:~# ifconfig

Deverá ser também possível contactar servidores Internet:

root@server:~# ping -c3 www.debian.org
