From 1fc21d3696cb108723bf7ab2b5d07a63e3701201 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Mon, 18 Nov 2013 19:06:06 +0100 Subject: utils: nfsynproxy: fix error while compiling the BPF filter Fix the following error while running nfsynproxy here: pcap_compile: not-yet-activated pcap_t passed to pcap_compile According to what I have read, we have to compile the filter once the pcap_t handle has been activated.
