This test should pass

  on systems with statically assigned IP addresses

  on systems with dynamically assigned IP addresses (DHCP)

This test will fail in some configurations we've seen

  on systems with dynamically assigned IP addresses (DHCP)
  where the hostname is on the 127.0.0.1 line in /etc/hosts.
  We consider this configuration unusual, although JR should work fine
  with it.
