Hi, The help text for NF_CONNTRACK_EVENTS reads: If this option is enabled, the connection tracking code will provide a notifier chain that can be used by other kernel code to get notified about changes in the connection tracking state. which sounds just like what I need: I want to execute a callback whenever a conntrack gets destroyed. However studying nf_conntrack_netlink.c, nf_conntrack_ecache.c and related header files for quite a while now, i am still unable to figure out how to do that. Can someone enlighten me? ______________________________________________________ GRATIS für alle WEB.DE-Nutzer: Die maxdome Movie-FLAT!
