Configure fixed IP address

Note: configure DHCP in your router to reserve the 'fixed' IP address of your machine. This way you can be sure every IP address is used only once.

Configure fixed IP address 192.168.1.8:

sudo gedit /etc/network/interfaces

#get IP from DHCP:
##auto lo
##iface lo inet loopback

#fixed IP:
auto eth0
iface eth0 inet static
	address 192.168.1.8
	netmask 255.255.255.0
	network 192.168.1.0
	broadcast 192.168.1.255
	gateway 192.168.1.1

DNS nameserver:

sudo gedit /etc/resolv.conf

nameserver 192.168.1.1

Restart networking:

sudo /etc/init.d/networking restart

List network interfaces:

ifconfig
