configurando rede na mão

# mii-tool

# ifconfig eth0 192.168.0.10 netmask 255.255.255.0
# route add default 192.168.0.1

ou
# ifconfig eth0 down
# route del default

nano /etc/resolv.conf

nameserver 200.204.0.10
nameserver 200.204.0.138

no iniciar
exemplo do /etc/network/interfaces

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet static
address 192.168.0.1
netmask 255.255.255.0
broadcast 192.168.0.255
gateway 192.168.0.1
network 192.168.0.0

para iniciar/parar/reiniciar o serviço de rede use o comando:

# /etc/init.d/networking {start|stop|restart}

compartilhando rede
considerando que a sua rede local seja: 192.168.0.0/24 (que significa a faixa de IPs de 192.168.0.1 até 192.168.0.254)

iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j MASQUERADE
echo "1" > /proc/sys/net/ipv4/ip_forward

# Limpando as tabelas
iptables -F
iptables -t nat -F
iptables -t mangle -F

* servidor dhcp
instalando
# apt-get install dhcp3-server

editando conf
# nano /etc/dhcp3/dhcpd.conf
