send command:
nano /etc/network/interfaces
now when you open interfaces you will see something like this:
# 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 inte loopback
#The primary network interface
auto eth0
iface eth0 inet dhcp
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inte loopback
#The primary network interface
auto eth0
iface eth0 inet dhcp
now to change it to a static ip change the file to look like this for example:
# 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 inte loopback
#The primary network interface
auto eth0
iface eth0 inet static
address 192.168.0.101
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inte loopback
#The primary network interface
auto eth0
iface eth0 inet static
address 192.168.0.101
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1
after you have made changes, save file and restart your network.
Next Step: Restart Network
