Configure eth0 on Raspberry Pi

Connecting my RasPi to my home LAN, was quite easy. Although, the no. of ways I could connect them together are many,  I decided to go the old-school way. Simply connect the Ethernet port of my Router and RasPi , via a straight through cable and get started. My router had already been assigned an IP address, i.e.  192.168.137.1

The next thing I had to do was configure the eth0 interface on my RasPi and assign it a static IP.

These are the steps I followed:

    1. Open the network interfaces file:
      sudo vi /etc/network/interfaces
    2. In there, replaced the following lines:
      auto eth0 
      iface eth0 inet dhcp
      with this:
      auto eth0
      iface eth0 inet static

      address 192.168.137.2
      netmask 255.255.255.0
      gateway 192.168.137.1
      nameserver 192.168.137.1

    3. Then opened resolv.conf file:    sudo vi /etc/resolv.conf
    4. In the file, removed all lines and typed in only this line:
      nameserver 192.168.137.1
      Where, 193.168.137.1 is my gateway, which would help me to connect my RasPi on LAN, with internet.
      Save the file and exit the file editor.
    5. Now in terminal, restart the network interfaces:
      sudo networking restart
    6. Then ping my gateway:
      ping 192.168.137.1
      If it pings, then, ethernet interface is ready to use, else you  should reboot RasPi and retry pinging again.
