Hi all, I'm studying iptables' source code (both user and kernel space) and got several questions and statements. I will highly appreciate if someone could confirm them. 1 - How to debug libiptc? I tried with TC_APPEND_ENTRY in libiptc.c by adding a print command and rebuilt iptables source code but it didn't show when I added a new rule. 2 - iptables utility (user space) and ip_tables module (kernel space) communicate with each other via getsockopt and setsockopt functions defined in TC_INIT of libiptc.c. 3 - Netlink (libnfnetlink) is only used for other modules (log, queue, conntrack). Not for iptables.
