libsys-hostname-long-perl 1.4-2 (i386 binary) in ubuntu saucy

 This module determines the host full name on multiple operating
 systems (MacOS, Windows, Unix-like systems; more later.)
 .
 The Sys::Hostname class is the best and standard way to get the basic
 hostname, but that may not be fully qualified. This module tries to
 determine the host's fully qualified name.
