Fellow monks, I've just started using Net::Pcap. I read the tutorial and the CPAN documentation. My syntax and usage of the lookupdev() and findalldevs() methods seems normal. However, when I run this script under linux, my script does not find any devices! At the same time, the exact same script running in Windows works just fine (except that lib_version() method seems to not be implemented). I can't help but wonder if this has anything to do with the pcap library on my linux installation (version 0.9.1). Does anyone have any ideas?

use strict;
use Net::Pcap;

$|++;
my $err;

print "pcap version " . Net::Pcap::lib_version() . "\n";

my %devinfo;
my @devs = Net::Pcap::findalldevs(\$err, \%devinfo);
if (defined $err) {
    die 'Unable to determine network device for monitoring - ', $err;
}

my $choice;
do {
    print "Please choose a device to monitor:\n";
    my $i = 0;
    for my $dev (@devs) {
        print ++$i . " - $dev : $devinfo{$dev}\n"
    }
    print "Choice: ";
    $choice = <>;
} while ($choice<1 or $choice>scalar(@devs));
