Hello, I am working with libnetfilter_conntrack library to provide my user-space. I download the current development version from https://git.netfilter.org/libnetfilter_conntrack/. In the meantime i tried to run some examples for better understanding. According to README guide, it should be compiled with "make check" , But id doesn't work. Also i just run one them with cc command like this: gcc -c utils/conntrack_dump_filter.c It compiled successfully but it doesn't work properly. How can i run them for more understanding? With Best Regards.Mojtaba -- --Mojtaba Esfandiari.S
