setup and Configuring Static ip address in Ubuntu server 12.04 through GUI mode

Method 1 : Configure network GUI mode

Step 1 : First find out the network interface to configure. Open a terminal and run ifconfig

ifconfig

Result will be something similar to below screenshot.

Step 2 : We will be assigning IP address to eth0 adapter. To do the same Click on “System Setting” and select “Network”

Step 3 : As eth0 is wired connection click on “wired”. Choose “ON” option and click on “Configure” button.

Step 4 : Go to “IPv4 Settings” tab. In case of DHCP / Automatic configuration choose “Automatic (DHCP)” option in “method”

In case of manual configuration select “Manual” option in “method”. Click on “Add” button. Enter IP Address, netmask and gateway information. Also enter DNS Server. In this example I am using google DNS server’s IP.

After finishing it up click on “Save” button.

To confirm the setting again run “ ifconfig ” command and check the “eth0″ interface settings. In case of successful configuration you will see something like below screenshot.

Method 2 : Configure network CLI Mode

Step 1 : First find out the network interface to configure. Open a terminal and run ifconfig

ifconfig

Result will be something similar to below screenshot.

Step 2 : We will be assigning IP address to eth0 adapter. Open a terminal and type

sudo vi /etc/network/interfaces

Step 3 : Now you need to add eth0 information in this file.
In case of DHCP / Automatic IP assignment enter following line and save this file.

iface eth0 inet dhcp

In case of manual IP assignment enter following line and save this file.

iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1

To configure DNS, enter following command. Remember to run it through “root” user

echo “nameserver 8.8.8.8″ >> /etc/resolve.conf

Step 4 : Now run following command to start eth0 interface

sudo ifup eth0
