Conntrack statistics

Hello, I am currently playing with the netfilter subsystem in a 2.6.7 kernel and a 2.6.28 kernel. In the 2.6.28 kernel I can get the number of packets and bytes for a conntrack using something like: struct nf_conn_counter *cnt = nf_conn_acct_find(conntrack); However, this relies on conntrack extensions, which do not exist in 2.6.7. Does anyone have any idea how I could accomplish the same effect in 2.6.7? I mean, the counters have to be somewhere, I just don't know where or how to reach them by having the conntrack structure. All the best, Silviu Popescu
