nf_queue question

[Stijn Souffriau]

Hello,

I wrote an application to analyze packets using a libnl netfilter queue 
but I'm not getting any packets in my queue (in fact the queued packets 
seem to be dropped in the iptables NFQUEUE target rule before they reach 
my application queue ). The application worked on another platform but 
not on my ubuntu pc. I think nf_queue or nfnetlink_queue module is not 
properly configured in ubuntu because the nfnetlink_queue module is not 
loaded by default(easily solved with modprobe) and I get

~$ cat /proc/net/netfilter/nf_queue
  0 NONE
  1 NONE
  2 NONE
  3 NONE
.....
12 NONE

whereas on the other platform this is

# cat /proc/net/netfilter/nf_queue
  0 NONE
  1 NONE
  2 nf_queue
  3 NONE
.....
12 NONE

I have no idea what this output means but I have a feeling the 
difference is important.
I hope someone can give me some pointers.

Thanks,
Stijn
