Fedora 23: FEDORA-2016-2bff7g6h1a Critical: IP Tables Vulnerability Alert

With conntrack-tools you can setup a High Availability cluster and

synchronize conntrack state between multiple firewalls.

The conntrack-tools package contains two programs:

- conntrack: the command line interface to interact with the connection

tracking system.

- conntrackd: the connection tracking userspace daemon that can be used to

deploy highly available GNU/Linux firewalls and collect

statistics of the firewall use.

conntrack is used to search, list, inspect and maintain the netfilter

connection tracking subsystem of the Linux kernel.

Using conntrack, you can dump a list of all (or a filtered selection of)

currently tracked connections, delete connections from the state table,

and even add new ones.

In addition, you can also monitor connection tracking events, e.g.

show an event message (one line) per newly established connection.
