How do I configure my DNS settings in Ubuntu server?

1

Set DNS Servers:

You need to configure the /etc/network/interfaces file if you want to change your DNS server via the command line.

It should look something like this:

# The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 192.168.X.X netmask 255.255.255.0 gateway 192.168.X.X dns-nameservers X.X.X.X

If you have more than one DNS server, just add a space between each:

dns-nameservers X.X.X.X Y.Y.Y.Y Z.Z.Z.Z

Just replace the Xs, Ys, and Zs with your own IPs of the DNS servers of choice, and when this is done, run this command to update the settings:

sudo ifdown eth0 && sudo ifup eth0

Hope this...

To configure your system on network and access internet. You also need to configure dns server. It is necessary to access websites by their name. When we visit a website, system first search for dns server we provided in configuration file. Then query to that DNS server for providing ip address corresponding to that domain.

Setup DNS Servers

Edit network configuration file (/etc/network/interfaces) on your system and add dns servers to specific network interface. In my system network interface is named as eth1. It may change in your system, So use name accordingly.

$ sudo vi /etc/network/interfaces auto lo iface lo inet loopback auto eth1 iface eth1 inet static address 192.168.1.100 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 8.8.8.8

As per above example we have added 8.8.8.8 as our dns server. If you need to add more than one dns, add them with space separated.

dns-nameservers 8.8.8.88.8.4.4

I'd make sure the network card is actually getting recognised by the system

sudo lspci | grep Ethernet

Should get an output e.g.

Text

05:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 11) 09:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 11)

Check your /etc/network/interfaces

cat /etc/network/interfaces

Text

# The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet dhcp

The above example shows that you have one network interface eth0 and it is set to dhcp

If you want to have your ip address set manually, edit the interfaces file
sudo pico /etc/network/interfaces

Text

auto eth0 iface eth0 inet static address 192.168.1.5 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 192.168.1.2 192.168.1.3 (two dns servers) dns-search domain.local (if you have a...

Introduction

An important part of managing server configuration and infrastructure includes maintaining an easy way to look up network interfaces and IP addresses by name, by setting up a proper Domain Name System (DNS). Using fully qualified domain names (FQDNs), instead of IP addresses, to specify network addresses eases the configuration of services and applications, and increases the maintainability of configuration files. Setting up your own DNS for your private network is a great way to improve the management of your servers.

In this tutorial, we will go over how to set up an internal DNS server, using the BIND name server software (BIND9) on Ubuntu 14.04, that can be used by your Virtual Private Servers (VPS) to resolve private host names and private IP addresses. This provides a central way to manage your internal hostnames and private IP addresses, which is indispensable when your environment expands to more than a few hosts.

Domain Name Service (DNS) is a Naming service that maps IP addresses and fully qualified domain names to one another. Computers that runs DNS are called name servers.

Here I have installed and configured cache server using forwarder, forward look-up and reserve look-up. In most of the place, we need a reserve lookups. Caching server will not hold any domain names, it will only work as a Pointing server. Before going in depth we need to know about DNS server and how it works.
