How to configure static IP in Ubuntu

1. Configuring a static IP address

$sudo vi/etc/network/interfaces

The original content only has the following two lines:

Auto Lo

Iface Lo inet Loopback

Append the following to the end:

Auto Eth0

Iface eth0 inet Static

Address 192.168.0.33

Gateway 192.168.0.1

Netmask 255.255.255.0

Network 192.168.0.0

Broadcast 192.168.0.255

then save the exit;

2. Configure DNS Manually

$sudo vi/etc/resolv.conf

Add the following to the end:

NameServer 192.168.0.10

Then save the exit.

3. Restart the network for changes to take effect

$sudo/etc/init.d/networking Restart

Here is a bit of a problem, is to restart Ubuntu after the discovery and can not surf the internet, the problem is/etc/resolv.conf. Once restarted, the DNS for this file configuration is automatically modified to the default value. So you need to permanently modify DNS. Here's how:

$sudo Vim/etc/resolvconf/resolv.conf.d/base

NameServer 202.96.209.6

NameServer 202.96.209.133
