Hourglass Howto
===============

This is a collection of programs (scripts) that implement an automated
network access control policy. The general idea is to declare the open
and close times for each weekday as well as a time limit of
accumulated usage during the open time.

For example, that the network should be open between 3pm and 8pm and
allow for 2 hours of usage within those times.

The Hourglass system includes four components:

 1. User interface for policy setting
 2. Continuous determination of network traffic (usage or not)
 3. Continuous determination of control action 
 4. Control actuator

Hourglass User Interface
------------------------

This software is an HTTP service aimed at editing the Hourglass
control policy, held in the +control.dat+ file, as well as the control
override setting, in file +control-extra.dat+, whilst also showing
current usage measure from file +usage.dat+.

The server +hourglass-web+ is first installed with
----
$ ./hourglass-web install
----
That installation sets up a small +www+ sub directory with "CGI"
scripting to provide the Hourglass User Interface on port 1070.
