The successor of "conntrack" is the conntrack-tools. http://people.netfilter.org/pablo/conntrack-tools/index.html
>From the website: The conntrack-tools are the userspace daemon conntrackd and the command line interface conntrack. The userspace daemon conntrackd can be used to enable high availability cluster-based stateful firewalls and collect statistics of the stateful firewall use. The command line interface conntrack provides a more flexible interface to the connnection tracking system than /proc/net/ip_conntrack. conntrackd covers the specific aspects of stateful Linux firewalls to enable high availability solutions and it can be used as statistics collector of the firewall use as well. The command line interface conntrack provides an interface to add, delete and update flow entries, list current active flows in plain text/XML, current IPv4 NAT'ed flows, reset counters atomically, flush the connection tracking table and monitor connection tracking events among many other. thx Csaba Szep Figyelmeztetés Ez az e-mail üzenet, a fenti címzetteknek szánt, üzleti titoktartás alá eső bizalmas információkat tartalmaz.
