Mikkel Krautz 8bd3f76a8e Murmur: add support for EDH cipher suites, and for specifying Diffie-Hellman parmeters.
This change allows server admins to specify Diffie-Hellman
parameters for Murmur to use. This is done using the sslDHParams
option in the config file. Diffie-Hellman parameters can also be
set on a per-server basis using the sslDHParams option.

Note: the functionality implemented in this change requires the
QSslDiffieHellmanParameters class in Qt, which has not yet landed
upstream in the Qt 5 'dev' branch. This means that the functionality
discussed in this change will, for now, only work in binaries provided
by the Mumble project, or binaries that are built using our build
environments, and not binaries that link against any released versions
of Qt at present.

This change modifies the default TLS cipher suite string to add
EDH+aRSA+AESGCM, DHE-RSA-AES256-SHA and DHE-RSA-AES128-SHA.

This yields the following ciphers, in TLS/RFC notation:

    TLS_DHE_RSA_WITH_AES_256_GCM_SHA384
    TLS_DHE_RSA_WITH_AES_128_GCM_SHA256
    TLS_DHE_RSA_WITH_AES_256_CBC_SHA
    TLS_DHE_RSA_WITH_AES_128_CBC_SHA

This change also allows Murmur servers to provide forward secrecy
to older clients, such as our own pre-built binaries before 1.2.9.

It also provides forward secrecy for users that use Mumble 1.2.x
versions on Linux distros, and other Unix-like systems. This is
because Mumble 1.2.x on Unix-like systems builds against Qt 4, which
limits the connection to TLS 1.0.

Before this change, Murmur was not able to negotiate an ephemeral
Diffie-Hellman key exchange for those clients. This is now possible.

 A voicechat utility for gamers

      #mumble on freenode

Mumble is a voicechat program for gamers written on top of Qt and Speex.

There are two modules in Mumble; the client (mumble) and the server
(murmur). The client works on Win32/64, Linux and Mac OS X, while the
server should work on anything Qt can be installed on.

Note that when we say Win32, we mean Windows XP or newer.

Running Mumble
==============

On Windows, after installation, you should have a new Mumble folder in your
Start Menu, from which you can start Mumble.

On Mac OS X, to install Mumble, drag the application from the downloaded
disk image into your /Applications folder.

Once Mumble is launched, you need a server to connect to. Either create your
own or join a friend's.

Running Murmur on Unix-like systems
===================================

Murmur should be run from the command line, so start a shell (command prompt)
and go to wherever you installed Mumble. Run murmur as

murmurd [-supw <password>] [-ini <inifile>] [-fg] [v]

-supw   Set new password for the user SuperUser, which is hardcoded to
        bypass ACLs. Keep this password safe. Until you set a password,
        the SuperUser is disabled. If you use this option, murmur will
        set the password in the database and then exit.

-ini    Use a inifile other than murmur.ini, use this to run several instances
        of murmur from the same directory. Make sure each instance is using
        a separate database.

-fg     Run in the foreground, logging to standard output.

-v      More verbose logging.

Running Murmur on Mac OS X
==========================

Murmur is distributed seperately from the Mumble client on Mac OS X.
It is called Static OS X Server and can be downloaded from the main webpage.

Once downloaded it can be run in the same way as on any other Unix-like system.
For more information please see the 'Running Murmur on Unix-like systems' above.

Running Murmur on Win32
=======================

Doubleclick the Murmur icon to start murmur. There will be a small icon on your
taskbar from which you can view the log.

To set the superuser password, run murmur with the parameters '-supw <password>'.

Bandwidth usage
===============

Mumble will use 10-40 kbit/s outgoing, and the same incoming for each user.
So if there are 10 other users on the server with you, your incoming
bandwidth requirement will be 100-400 kbit/s if they all talk at the same time.
