## Installation

Dowload the software, either using Git, or grab a [ZIP](https://github.com/longsleep/realtimetraffic/archive/master.zip) and extract it somewhere.

You can use the client right away without installation. Just open the file client/realtimetraffic.html in any modern browser, type in a WebSocket address of a server you started somewhere and press start.

To install the server, make sure you have [Python](http://www.python.org) (2.5, 2.6, 2.7 tested) and [tornado](http://pypi.python.org/pypi/tornado). For Python << 2.6 you also need [simplejson](http://pypi.python.org/pypi/simplejson). Then just startup the server.

On Ubuntu this is simple like this:

    $ wget -O rtt.zip https://github.com/longsleep/realtimetraffic/archive/master.zip
    $ unzip rtt.zip
    $ cd realtimetraffic-master
    $ sudo apt-get install python-tornado
    $ python trafficserver/trafficserver.py
    Server running on 127.0.0.1:8088 (ssl:False) ...

Now just open up your browser:

    $ firefox http://127.0.0.1:8088/?autostart=1

## Getting Started

Startup the traffice server on a Linux machine of your choice.

    $ python trafficserver/trafficserver.py

And open up the server's web page (http://yourserver:8088/).

See the usage information (--help) for options.

## Server usage options

The trafficserver is basically a Websocket server pushing traffic data to any connected client.

```

  -h, --help            show this help message and exit
  -l LISTEN, --listen=LISTEN
                        listen address (default: [127.0.0.1:8088])
  --ssl_keyfile=FILE    SSL key file
  --ssl_certfile=FILE   SSL certificate file
```

## Client parameters

The client default parameters can be configured by URL query parameters.
