• Ubuntu Network Configuration

Most ethernet configuration is centralized in a single file, /etc/network/interfaces.

To assign the IP address 192.168.0.2 to the device eth0, with the typical netmask of 255.255.255.0. Your default gateway's IP address is 192.168.0.1. You would enter something like this into /etc/network/interfaces:

iface eth0 inet static

	address 192.168.0.2
	netmask 255.255.255.0
	gateway 192.168.0.1

• Specify your DNS servers manually in /etc/resolv.conf, which should look something like this:

       nameserver 4.2.2.2

• To manage hosts:
  Add, edit, or remove hosts from /etc/hosts file.
