First off, Alfredo thanks for answering all my questions as I get up to speed on PF_RING.
I have a few other questions based off of some /proc/net/pf_ring/ output. 1. In the first cat I have 0 free slots and the second 13k, am I dropping traffic when there aren't free slots? Should I increase the slots even more? 2. Why do I have lost packets? I have some rings with 0% and others with about 5% packet drops. Is this normal? 3. My capture mode is set for RX only in the info file, but the ring file says both? 4. Is socket mode something I should worry about?
