Hi all
you are using an old version of the code as now DNA interfaces are named
dnaX. Please fetch the latest code and drivers from SVN

Chris,
Thanks for your response. I am running pfcount as root. I don't see
the error for "pfcount -i eth2" only for "pfcount -i dna:eth2".
In my configuration, I don't expect to receive much traffic. I am
connecting two machines with 10 GbE NICs back-to-back. So the only
traffic I expect to see (for now) are the pings that I am attempting
to send; so the number of received packets is on the order of what I
would expect.

Hi Scott,
You'll see that error when you run pfcount without su permission (make sure
you sudo or use root). Not sure if that's your problem or not, i'm still
figuring this out myself...
On the other hand it doesn't look like you're receiving much. Your RX
packets are 210, whereas mine after an hour is...

Subject: Re: [Ntop-misc] Problems with pfcount
I've updated my PF_RING code and I'm not seeing any difference (i.e.,
pfcount -i eth2 still shows 0 packets received but ifconfig shows
packets being received). Here's what I'm seeing with the new version:
ifconfig eth2

I also tried pfcount -i dna:eth2, but got the following error:

and have already a socket bound to dna:eth2 ?)

please redo your tests using the code in PF_RING's SVN. From the
interface names (we now call them dnaX) i see that you are using old stuff

I'm having problems getting pfcount to work. I have two machines
connected back-to-back: (A) has a Silicom NIC ; and (B) has a
NetEffect 10GbE NIC. I launch pfcount on A. Then on B I start
pinging A. pfcount continually reports zero packets received.

The only relevant log messages I see are:

As I look around I don't see the problem. I can see the packets as
they are transmitted on B. And the RX packet count for eth2 that is
displayed by ifconfig increments appropriately on A. But pfcount
doesn't see them. Anyone have any suggestions?
