cfengine2 -- Tool for configuring and maintaining network machines<hr>
<a href="http://www.cfengine.org/">http://www.cfengine.org/</a><hr>
The main purpose of cfengine is to allow the system administrator to
create a single central file which will define how every host should
be configured.

It takes a while to set up cfengine for a network (especially an already
existing network), but once that is done you will wonder how you ever
lived without it!
