Re: libipq/payload doubt

[Ulysses Almeida <munky@maluco.com.br>]

  Thanks, all, I just tried with htons(), and every thing works fine.

  Now I another doubt. I alredy read ip_queue.c, and alredy understood,
that payload is skb->data.

 ---
  memcpy(pmsg->payload, entry->skb->data, data_len);
 ---

  But, skb->data isn't clear enough on my head. If I queue every packge,
can I know which type is it? (TCP/UDP/ICMP), just looking for payload?
  Packet data, can be analyzed on userspace, or maybe changed?

  How can i get a payload X-ray?

  When i tried something like printf ("%d\n", tcph->syn); i started to
recive "passer: Received message truncated: No such file or directory"
from my program. What is it means?

  The last question, probably I can easily find on google, but the
other ones, I can't find that easy

  I think that's it for today! (One day I'll be able to answer
begginers question, yes I will, I belive in that! ;))
