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
whereas on the other platform this is
# cat /proc/net/netfilter/nf_queue
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.
