Hi to everybody,
I'm new to the mailinglist and I have a little question.
I have an application that take packet from the QUEUE target by libipq API.
This application take this packets and send them in a specific order
selected by me.
when I send this packets I print its packet_id with this line of code:
ipq_set_verdict(h, queue[elem]->packet_id,NF_ACCEPT, 0, NULL);
fprintf(stderr,"I'm sending packet number: %d with packet_id:
%lu\n",elem+1,queue[elem]->packet_id);
note that queue is a standard vector where i copy packet got from QUEUE
for my elaboration.
I'm wondering that some of this packet_id have the same id!
for example, this is my output:
I'm sending packet number: 1 -> packet_id: 4154682432
count_tot_pkt: 1
/proc/net/ip_queue: 2
I'm sending packet number: 1 -> packet_id: 4019277504
I'm sending packet number: 2 -> packet_id: 4148198144
I'm sending packet number: 3 -> packet_id: 4154682432
count_tot_pkt: 4
/proc/net/ip_queue: 4
I'm sending packet number: 1 -> packet_id: 4154682432
I'm sending packet number: 2 -> packet_id: 4148198144
I'm sending packet number: 3 -> packet_id: 4020406400
I'm sending packet number: 4 -> packet_id: 4021517504
...
and so on
as you can see some of this packet have the same packet_id,but i'm sure
that this packet (send from another application) are not equal (for
example have different payload) now my question is:
what dose esactly means packet_id?
why some of this are the same?
I try to find out some documentation about packet_id, but I'm not lucky :(
tnx in advance
ps.sorry for my bad english
