Hi Alfredo

thank you for your fast response. 
Do you have any instructions how to link pf_ring aware libpcap? Seems that we are using it wrong.

Thank you,
Katarina

Hi Katarina
pcount and tcpdump in the pf_ring tarball are our libpcap-based sample applications you can use for testing,
please make sure tshark is linked against our pf_ring-aware libpcap.

Hi
 
We have been using PF_RING TNAPI and Intel 1G card with an java application that used jnetpcap and libpcap to receive packets from PF_RING. Now we are trying to upgrade existing system to use Intel 10G 82599 card and PF_RING ZC.
 
Using instructions from https://svn.ntop.org/svn/ntop/trunk/PF_RING/userland/examples_zc/README.quickstartwe have installed ZC ixgbe driver and PF_RING. Additionaly, we have copied libpcap from PF_RING into usr/lib and linked it with libpcap.so.1 because we use jnetpcap and libpcap in our java application.
Usage of example program zcount seems to be working fine, but we cannot se packets using tshark tool. Is there something extra we need to do to see these packets? Our fear is that if tshark doesn't see packets, our application also won't see them. Do we need to use some other JNI in our applicatio for it to work with PF_RING ZC?
 
Thank you,
Katarina Valent
