Thousands of companies and organizations are moving their data to the web
everyday, asking both their clients and users to rely on this medium as
their main point of information. You are committed to provide your
clients a high-availability web site and need redundant systems to supply
this level of service. Right now, your firewall may be your single point of
failure. Protect your company and your uptime with fCluster.
fCluster solves your need for redundancy by allowing you to set up master
and slave Linux firewalls that provide fail over protection for your
mission critical sites.
fCluster uses a master/slave model to provide redundancy. The slave
(client) system is configured to poll the master (server) to find the state
of the machine. The client will check to make sure that it has the most
current version of the firewall, the firewall is running on the master
system, and that the server is running. If the firewall on the server is
more current, the client will update itself eliminating the need to make
firewall changes on both your master and slave systems!
When the client
senses that the server has failed it will begin a fail-over sequence. If
the server recovers at any point during this time, the fail-over sequence
is stopped and the client will resume its normal polling interval. When the
client fails over, it assumes the identity of the server and activates the
most current firewall. Polling intervals, retry counts, and alert addresses
are all configurable so that you have control over your fCluster system.
fCluster is a multi-threaded client/server redundancy application. fCluster
is designed for the production environment with features that include:
Dynamic firewall synchronization
A Perl administration utility
Configure both server and client from one machine
View status of the local and remote machines
Support for both ipchains and netfilter
User definable polling intervals and fail-over sequence
