Redes

configurando rede na mão

# ifconfig eth0 192.168.0.10 netmask 255.255.255.0
# route add default 192.168.0.1

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

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

# apt-get install dhcp3-server

editando conf

# nano /etc/dhcp3/dhcpd.conf
