sudo: unable to resolve host (none)

My Ubuntu 12.04 LTS lost Internet connection. It just acts like it has lost Internet connection.

When I go to terminal in says: user@(none). When I run any sudo command, it says

sudo: unable to resolve host (none)

If I try Firefox, nothing happens. But when I try pinging, it responds fine (but only if it has been pointed to a IP address).

    nano /etc/hostname

    And tell me what it says :)
