libnet-ping-external-perl binary package in Ubuntu Xenial i386

 Net::Ping::External is a module which interfaces with the "ping"
 command on many systems. It presently provides a single function,
 ping(), that takes in a hostname and (optionally) a timeout and
 returns true if the host is alive, and false otherwise. Unless
 you have the ability (and willingness) to run your scripts as
 the superuser on your system, this module will probably provide
 more accurate results than Net::Ping will.
