Question

We are trying to deploy our Rails app using Passenger and Nginx on a Linode Ubuntu 10.04 Lucid box.

We cant seem to set the hostname from the root IPv6 address of our Ubuntu box.

We get the error:

root@`ourIPv6`:~# hostname -f
hostname: Name or service not known

when i type in hostname it returns myhost
however when I type in hostname -f it returns hostname: Name or service not known

What would be the necessary action to take to set the hostname?

hosts file:
    ##
    # Host Database
    #
    # localhost is used to configure the loopback interface
    # when the system is booting. Do not change this entry.
    ##
    127.0.0.1 localhost
    255.255.255.255 broadcasthost
    ::1 localhost
    fe80::1%lo0 localhost

    97.107.128.97 plato.example.com   plato

Answer 1

Edit /etc/hostname and /etc/hosts and make sure that the hostname you want is in your hosts file there and then do #: hostname -F /etc/hostname.
