I think you mean open (IN, "<hostnames.txt" ) || die "Can't open hostnames.txt";

Try something more like this?

#!/usr/bin/perl -w
use strict;

use IO::Socket::PortState qw(check_ports);

my $proto = 'tcp';
my $port = '23';
my $service = 'telnet port';
my $address = '70.114.230.116'; 
my $porthash{$proto}->{$port}->{'name'} = $section;
check_ports( $address, $ping_timeout, \%porthash );
my $open = $porthash{$proto}->{$port}->{'open'};
if ($open) {
        print "alive\n";
}
else {
        print "dead\n";
}
