can you please resync from SVN and see if it now works for you
manually copied
it into the kernel/plugins (it is dummy_plugin.c that complained about
missing header) and it compiled.
Cheers,
Thierry.

Daniel,
I have no idea about this, but there isn't a limit if the number if reasonable.
Said this, I want to tell you that PF_RING was no optimized for a large number
of rings: this is on my todo list and I will work at it by this spring when I
have in mind to rework PF_RING quite a bit
Thanks Piotr: I have just committed it

Hi all
Thanks to all. The new driver release is in SVN

if you use multiqueue, you have packet timestamp coherency only inside a
queue, but not across queues. This is the way hw works. Note that you can
bind PF_RING to multiple queues simultaneously or all at the same time.

in the latest nProbe version we have made some changes, so that we avoid
loops caused by nProbe exporting flows with -n. Please update to the latest
nProbe.
Said that I would do
nprobe --collector-port 2055 -i none -n none -F 300 -P /tmp/flows
If you want to debug the issue, you can use
feedback) appears to be getting full flow, so the
configuration on the routers doesn't appear to be at fault.
Thanks for the response, I'll upgrade ASAP and keep trying.

I would appreciate if you could fill in a bug in
https://www.ntop.org/bugzilla3/ so I can track the issues you encountered and
fix them in the next release.
Thanks Luca

thanks for the problem report. Can you please check if the PF_RING code,
currently in the SVN, works for you?

you can start with the standard driver, but if you use the PF_RING version of
the driver, you can use PF_RING in transparent_mode=1 or 2 that is faster.
Please make sure you compile snort on top of DAQ
(https://svn.ntop.org/svn/ntop/trunk/PF_RING/userland/snort/)

multiqueue is supported on recent kernels. I doubt 2.6.18 can support that

I would prefer to run PF_RING in transparent mode since I need it for a very

in my tests with 2 cores you can definitively capture at least 1 Gbit
(1.48 Mpps). How did you balance irq/threads/pfcount across cores? How
did you start pfcount?

Rui
if you out the card in promiscuous move (e.g. via pfcount) you drop traffic as
traffic is not discarded by the NIC. Unless you have balance-able traffic (i.e.
if you send always the same packet it will definitively go onto the same queue)
all you observe is correct. Please read some of my
correctly.

Martin

no license issues: there isn't such limitation in the code. 7k pps is nothing.
Is maybe your machine busy with other tasks? What is the overall system load?
What server/CPU do you use? Other packet capture apps such as wireshark or
tcpdump behave the same or you see no drops with them?
