Hi there, I am asking for your instructions to generate statistics for a TCP flow using conntrack? In my use case, a TCP flow consists of packets from host_a:port_a to host_b:port_b and statistics could be average packet size or average window size, per TCP flow. My plan is to add a hook into TCP connection tracking module (nf_conntrack_proto_tcp.c) and collect statistics per TCP flow. However, I don't know how conntrack relates to netfilter. Can I write a netfilter hook and access the tcp_conntracks table? Or should I put the hook in the tcp_new() function in nf_conntrack_proto_tcp.c? Please let me know your suggestions on this issue. Thanks! - PC -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
