Hi. I created a Perl app that searches Airodump's output plain text file for MAC addresses and matches one that is specified. I would like to have no dependencies anymore and I would like to create a program that reads all data from a wireless device that is NOT associated with an AP, but simply sniffing (wardriving).

I have the proper drivers installed on WeakNet Linux to sniff in promiscuous mode, and I can with Airodump-ng.

I have tried utilizing all I can in CPAN, including: Net::Pcap; Net::PcapUtils; NetPacket::Ethernet;

None seem to work properly when I specify a wireless device rather than a wired device and all I want to do is to be able to drive around and decode the packets from, say, wlan0 to pull out MAC addresses in which i can search for a particular MAC specified.

I would rather not have someone else code this as I would like to learn more than anything, but I just want to know the right direction. Or maybe have some code samples.

Thanks in advance,

Douglas. here is the code I have that produces output, just wrong output:
#!/usr/bin/perl -w
use Net::Pcap;
use NetPacket::Ethernet;
use strict;
my $err;
my $dev = "wlan0";
my $object;
$object = Net::Pcap::open_live($dev, 2048, 0, 0, \$err);
Net::Pcap::loop($object, -1, \&syn_packets, '') || die 'Unable to perf
+orm packet capture';
Net::Pcap::close($object);
sub syn_packets {
        my ($user_data, $header, $packet) = @_;
        my $eth_obj = NetPacket::Ethernet->decode($packet);
        print("$eth_obj->{src_mac} : $eth_obj->{dest_mac}\n");
                }
