Introduction
============
Mcproxy is an IGMP/MLD Proxy daemon for Linux.

IGMP/MLD proxies offer the possibility option to combine local multicast
networks with a larger multicast infrastructure. In contrast to multicast
routers, proxies are lightweight and do not require the support of a multicast
routing protocol such as PIM or DVMRP. A common use case is a local stub
networks that interconnects with a remote multicast routing domain, e.g. via a
tunnel. But it can also be used in PMIPv6 domain to enable multicast for
sources
([pmipv6-source-draft](http://tools.ietf.org/html/draft-ietf-multimob-pmipv6-source))
and listeners ([RFC 6224](http://tools.ietf.org/html/rfc6224)). The Mcproxy
meets the requirements of the IGMP/MLD proxying standard ([RFC
        4605](http://tools.ietf.org/html/rfc4605)) and has additional
functionalities.  The multicast proxy can be instantiated multiple times, is
dynamically configurable at runtime, supports multiple upstreams and
peering-interfaces for a non hierarchical interconnection of multicast proxies.

If you use Mcproxy in a scientific context, please use the following [citation](http://inet.cpt.haw-hamburg.de/publications/sww-pmpps-14.html).

Requirements
============
*  A g++ version equal or higher **4.8** is required.

*  To generate a makefile, qmake must be installed. This can be done with the
following command:
  
  newer systems: 

        apt-get install qt5-qmake
        apt-get install qt5-default

  older systems: 

        apt-get install qt4-qmake

*  To use the IPv6 functionality the kernel has to be configured and compiled
with the experimental kernel feature _IPv6: multicast routing_.  For more
details go to chapter [Startup](#startup).

*  To use more then one proxy instance for IPv4 and IPv6 the kernel has to  be
configured and compiled with the experimental kernel feature _IP: multicast
policy routing_ and _IPv6: multicast policy routing_.  For more details go to
chapter [Startup](#startup).

*  To build the documentation, doxygen must be installed. This can be done with
the following command:

        apt-get install doxygen

*  The Mcproxy has to be started with root privileges.

*  A Linux kernel version greater than version 2.6.32 is required.


Compilation
===========
Build Mcproxy in release mode:

    cd mcproxy/
    qmake 
    make

Build Mcproxy in debug mode:

    cd mcproxy/
    qmake CONFIG+=debug
    make


Installation
============
To copy Mcproxy to the system directory, run (optional):

    make install


Documentation
=============
Mcproxy includes a HTML documentation. The documentation will be located in the
docs/ directory after the execution of:

    make doc


Startup
=======
At first you should check the available kernel features of your system. Type
the following command:

    sudo mcproxy -c
   
If a kernel feature you need is missing you have to reconfigure and recompile
your linux kernel. In the debug folder is a [README](debug/README.md#kernel) file
which could help you with this problem.

To run the Mcproxy you need to create a valid configuration file.  There is an
example in the project folder ([mcproxy.conf](mcproxy/mcproxy.conf)).

*  To run the Mcproxy in the background type the following command:

        sudo nohup mcproxy -f <path/to/config_file> &

*  To run the mcprocy with all available status and debug messages:

        sudo mcproxy -dsvv -f <path/to/config_file>

For more information see `mcproxy -h` or visit our project page.
