I'm using V 2.02 of Net::Ping, but for some reason nothing will work. I understand that 'icmp' pings require UID 0 (root) (someone told me that Net::Ping sends raw packets, hence the need for root). But, I can't get TCP or UDP pings to work either.

I thought it might be some kind of permissions issue, but the test script runs with my UID (i've watched it in the process list), and i've been able to ping the boxes (both with backticks and from ping in the shell - same thing, i know - so it's not a question of permissions.

or is it? here's the code (straight outta the documentation): 


use Net::Ping;


my @host_array = qw( www.slashdot.org www.deja.com  www.perlmonks.org 
+);

my $proto = 'tcp';
my $def_timeout = '40';
my $bytes = '52';

my $p = Net::Ping->new($proto,  $def_timeout , $bytes);

   foreach my $host (@host_array) {
            print "$host is ";
            print "NOT " unless $p->ping($host, 2);
            print "reachable.\n";
        }

$p->close();

and when i run it: 
bclarkso-sun:/users/bclarkso/snips --> perl -w ping.pl
www.slashdot.org is NOT reachable.
www.deja.com is NOT reachable.
www.perlmonks.org is NOT reachable.
