About Django Conntrackt
=======================

Django Conntrackt is a simple application targeted at system
administrators and integrators that deploy servers at client's
premises that need a way to keep track of required network
connectivity.

Application allows tracking of required network communications between
different servers, routers, client workstations, and even whole
networks/sub-networks.

In addition to keeping track of connections, the application has the ability to
generate simple *iptables* rules based on the connections specified. The
generated rules can be easily applied using the *iptables-restore* utility.

At time of this writing, Django Conntrackt is compatible with the
following Django and Python versions:

- *Python 2.7.x*
- *Django 1.11.x*

In addition, *Django Conntrackt* uses the following external
dependencies:

- `Graphviz <https://graphviz.org/>`_


Why was this application created?
---------------------------------

The application was created in order to alleviate painful and error prone
tracking of IP addresses and network communications inside of spreadsheet
files. Another reason was the need to create simple iptables rules based on this
information with as little hassle as possible.

The *iptables* generation requirements for Django Conntrackt were farily simple,
and do not include any complex functionality. It all boils down to rejecting all
communication except for explicitly defined links.


Features
--------

Django Conntrackt sports a number of useful features for system administrators
and integrators:

* Managing entities through multiple projects (separating the entities
  per-project basis).
* Grouping entities inside of a project in one or more locations (which can be
  either logical or physical).
* Specifying entities that represent servers, routers, workstations, networks,
  subnets or any other networked device or abstraction within a network.
* Specifying multiple network interfaces for each entity.
* Specifying the communication link between two entities, which includes
  information such as protocol and port.
* Generation of *iptables* rules for devices based on GNU/Linux that can be
  consumed by the *iptables-restore* utility.
* Generation of *iptables* rules on per-location/project basis (multiple
  *iptables* rule files inside of a single *ZIP* file).
