Hi! The netfilter project presents another development release of the conntrack-tools that includes support for all the protocol helpers available in 2.6.30 that were missing so far (SCTP, UDPlite, DCCP and GRE). The daemon updates includes a fix for a memory leak that can be triggered under heavy load and if you set a hashtable in user-space that is smaller than the one in the kernel. Moreover, it adds initial support for DCCP and SCTP state-synchronization. Please, see changelog attached for more details. Q: How stable are the conntrack-tools? A: This software is under development. Nevertheless, it has been tested in a cluster environment composed of two stateful firewalls running Debian 4.0 (Etch) with a Linux kernel 2.6.28, keepalived 1.1.15, using conntrackd in FT-FW mode, randomly (in periods of 10 seconds) setting links down to force the fail-over between the nodes. The results has shown no hangs/closure in any TCP connection. Q: What are the conntrack-tools? A: The conntrack-tools are: - The userspace daemon so-called conntrackd that covers the specific aspects of stateful Linux firewalls to enable high availability solutions. It can be used as statistics collector of the firewall use as well. The daemon is highly configurable and easily extensible. - The command line interface (CLI) conntrack that 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, and flush the complete connection tracking table among many other.
