I am using net::pcap module to capture packets with this filter:
dst $my_host and dst port 80
inside the net::pcap::loop i use the below callback function:
net::pcap::loop($pcap_t,-1,\my_callback,'')
where my_callback look like this :
my_callback {
my ($user_data, $header, $packet) = @_;
# Strip ethernet IP and TCP
my $ether_data = NetPacket::Ethernet::strip($packet);
my $ip = NetPacket::IP->decode($ether_data);
my $tcp = NetPacket::TCP->decode($ip->{'data'});
}
could someone help me how can i assemble the http packets to one packet and extract its header .
