  • DNS troubles with Ubuntu Server 12.04

    Some customers have been having DNS issues after setting a static IP on Ubuntu 12.04.1 where the server is no longer picking up the DNS settings as it was before; this can be easily fixed by adding the following to /etc/network/interfaces after the eth0 entry:

     

    dns-nameservers [ip.of.your.router]

     

    e.g., for a modem/router that’s 10.1.1.1 on your local network, your /etc/network/interfaces file might look like:

     

    # This file describes the network interfaces available on your system
    # and how to activate them. For more information, see interfaces(5).

    # The loopback network interface
    auto lo
    iface lo inet loopback

    # The primary network interface
    auto eth0
    iface eth0 inet static
    address 10.1.1.50
    netmask 255.255.255.0
    gateway 10.1.1.1
    broadcast 10.1.1.255

    dns-nameservers 10.1.1.1

    Restart your network with:

     

    sudo /etc/init.d/networking restart

     

    …then try pinging Google or something similar and you should have success 🙂

     

    It’s generally not advisable for Australians to use nameservers located elsewhere, e.g. Google’s public DNS’ 8.8.8.8 or 8.8.4.4 – some things which are unmetered by your ISP may be metered if you do so.
