Dear Yuri,
I am a very newbie to pf_ring. So I want to write an
application which will read the packet header and store in a db. So I was
thinking to learn it basis from pfcount so that is why I tried to make a copy
of pfcount rename as pf1 and would like to modify to learn how things are done.
If that is wrong move for me please guide me. Thank you. Below is how I compile
and errors. Where can I learn the basic programming for pf_ring as is stated in
the user guide.

I can't understand the reason why you are doing that.If you are not able to
compile by yourself pfcount, use the one provided by Luca and you will be sure
it will work out of the box.Y

I would like to share with you something. What I did this I
had reformated my machine and had a clean centos 6. I did all the steps work
well according to your user guide using svn method, all worked fine except for
this step insmod pf_ring.ko when I put the option I get error. So what I did
was just put this type this insmod pf_ring.ko it got registered. Next I run cat
/proc/net/pf_ring/info and below is the information I get.
PF_RING Version : 5.1.0 ($Revision: 4971$)
Ring slots : 4096
Slot version : 13
Capture TX : Yes [RX+TX]
IP Defragment : No
Socket Mode : Standard
Transparent mode : Yes (mode 0)
Total rings : 1
Total plugins : 0
The problem now I copied your pfcount.c and rename is pf1.c I did a gcc -o pf1
pf1.c and I get a whole lot of errors. So what else am I missing why I cannot
compile properly? After the clean installation now in my /usr/local/lib is only
2 files libpfring.a and libpfring.so. The example like pfcount run perfectly
fine. Did I miss any steps? Thank you.

Dear Yuri,
Further to my steps I went into the userland/libpcap folder and
also run make install. Now what I can see in my /usr/local/lib the files are
libpcap.a, libpcap.so.1,libpring.a,libpcap.so,libpcap.so.1.1.1 and
libpfring.so. So what else am I missing yet? Thank you.

By default it is installed in /usr/local/lib/ and I don't know if it is added
into your ld.so.conf fileY

Dear Yuri,
How to check on the pfring lib got install into my directory or
not? Because what I did I went into PR_RING-4.6.0/userland/lib then I run make
install command here. So what else command must I run?

Did you add the pfring lib install directory to your library path?Y

I went into userland/lib and run make install. So now I
