I'm attempting to make sure that a host is up before I try to get some info from it, so I am using Net::Ping to test for this. The problem is when I try to redirect STDOUT, I get nothing. I can't redirect to a file and writing to a file doesn't work either though the screen output works just fine. Here are some examples of code that works and doesn't work: 
# this code works
# loop.pl > loop.txt has > 0 bytes

use Net::Ping;

my $adr = "192.168.";
my @net = qw / 97. 100. 102. 104. 105. 32. 33. 34. /;
my ($i, $j, $host);

for ($i=0; $i<=7; $i++) {
    HOST: for ($j=16; $j<=250; $j++) {
        $host = $adr . $net[$i] . $j;
            print "$host\n";
    }
}

This, on the other hand, doesn't work: 
use Net::Ping;

my $adr = "192.168.";
my @net = qw / 97. 100. 102. 104. 105. 32. 33. 34. /;
my ($i, $j, $host);

$p = Net::Ping->new() or die "Can't create ping object: $!\n";

for ($i=0; $i<=7; $i++) {
    HOST: for ($j=16; $j<=250; $j++) {
        $host = $adr . $net[$i] . $j;
        if (!$p->ping($host)) {
            print "$host not responding!\n";
            next HOST;
        } else {
            print "$host\n";
        }
    }
}

The HOST tag is for a jump that happens in the else clause. The output from the second script is like thus: 
192.168.97.16
192.168.97.17
192.168.97.18
192.168.97.19
192.168.97.20
192.168.97.21
192.168.97.22
192.168.97.23
192.168.97.24
192.168.97.25
192.168.97.26 not responding!
192.168.97.27
but when I do ./ploop.pl > ploop.txt, ploop.txt is a 0 byte file and if I open and write to file, still nothing gets written to it. I don't understand what is happening. Anyone have a clue? Thanks in advance
