sudo vi /etc/network/interfaces
## To configure a dynamic IP address
auto eth0
iface eth0 inet dhcp
## Or configure a static IP
auto eth0
iface eth0 inet static
address 192.168.1.14
gateway 192.168.1.1
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
For these settings to take effect you need to restart your networking services.
sudo /etc/init.d/networking restart
If you need to set up a second ip address you need to edit the /etc/network/interfaces.
sudo vi /etc/network/interfacesauto eth0:1iface eth0:1 inet static address 192.168.1.24 netmask 255.255.255.0 network 192.168.1.1 broadcast 192.168.1.255 gateway 192.168.1.1
For these new settings to take effect you need to restart networking services using the following command
sudo /etc/init.d/networking restart
