    The system call gethostbyname(3) failed to resolve your
    unqualified hostname, or $uqhn. This can be caused by
    missing info from your /etc/hosts file or your system not
    having correctly configured name resolvers, or by your IP
    address not existing in resolution services.
    If you run DNS, you may wish to make sure that your
    DNS server has the correct forward A set up for yout machine's
    hostname. If you are not using DNS and are only using hosts
    files, please check that a line similar to the one below exists
    in your /etc/hosts file:
$ipaddr $uqdn
    If you plan to use DNS but you are not sure that it is
    correctly configured, please check that the file /etc/resolv.conf
    contains entries similar to the following:
nameserver 1.2.3.4
    where 1.2.3.4 is an actual IP of one of your nameservers.

and the /etc/hosts :

 hosts         This file describes a number of hostname-to-address
#               mappings for the TCP/IP subsystem.  It is mostly
#               used at boot time, when no name servers are running.
#               On small systems, this file can be used instead of a
#               "named" name server.
# Syntax:
#
# IP-Address  Full-Qualified-Hostname  Short-Hostname
#

127.0.0.1       localhost
192.168.1.2     node2
192.168.1.3     node3
192.168.1.4     node4
192.168.1.5     node5
