## Compilation

Install libraries including developement headers for:

 - libconfig

Start the compilation with:

	$ make

Add `V=5` for a more verbose debugging output.

## Installation

Install the server by executing:

	$ sudo make install

Add `PREFIX=/usr/local/` to specify a non-standard installation destination.

**Important:** Please note that the server requires the
[iproute2](http://www.linuxfoundation.org/collaborate/workgroups/networking/iproute2)
tools to setup the network emulation and interfaces.

Install these via:

	$ sudo yum install iproute2

or:

	$ sudo apt-get install iproute2

## Configuration

See [configuration](Configuration.md) for more information.

## Usage

The S2SS server (`server`) expects the path to a configuration file as a single argument.

The server requires root privileges during the startup.
Afterwards privileges can be dropped by using the `user` and `group` settings in the config file.

	Usage: ./server CONFIG
	  CONFIG is a required path to a configuration file
