Depuis les ports :

portupgrade -N murmur

On change les droits des différents répertoires (par défaut, tous les répertoires appartiennent à root) :

chown murmur /var/log/murmur/ /var/db/murmur/ /var/run/murmur/

Un example de fichier de configuration :

# Path to database. If blank, will search for
# murmur.sqlite in default locations or create it if not found.
database=/var/db/murmur/murmur.sqlite

# If you wish to use something other than SQLite, you'll need to set the name
# of the database above, and also uncomment the below.
# Sticking with SQLite is strongly recommended, as it's the most well tested
# and by far the fastest solution.
#
#dbDriver=QMYSQL
#dbUsername=
#dbPassword=
#dbHost=
#dbPort=
#dbPrefix=murmur_
#dbOpts=

# Murmur defaults to not using D-Bus. If you wish to use dbus, which is one of the
# RPC methods available in murmur, please specify so here.
#
dbus=session

# Alternate service name. Only use if you are running distinct
# murmurd processes connected to the same D-Bus daemon.
#dbusservice=net.sourceforge.mumble.murmur

# If you want to use ZeroC Ice to communicate with Murmur, you need
# to specify the endpoint to use. Since there is no authentication
# with ICE, you should only use it if you trust all the users who have
# shell access to your machine.
# Please see the ICE documentation on how to specify endpoints.
#ice="tcp -h 127.0.0.1 -p 6502"

# Ice primarily uses local sockets. This means anyone who has a
# user account on your machine can connect to the Ice services.
# You can set a plaintext "secret" on the Ice connection, and
# any script attempting to access must then have this secret
# (as context with name "secret").
# Access is split in read (look only) and write (modify) 
# operations. Write access always includes read access,
# unless read is explicitly denied (see note below).
#
# Note that if this is uncommented and with empty content,
# access will be denied.

#icesecretread=
icesecretwrite=

# How many login attempts do we tolerate from one IP
# inside a given timeframe before we ban the connection?
# Note that this is global (shared between all virtual servers), and that
# it counts both successfull and unsuccessfull connection attempts.
# Set either Attempts or Timeframe to 0 to disable.
autobanAttempts = 10
autobanTimeframe = 120
autobanTime = 300

# Murmur default to logging to murmur.log. If you leave this blank,
# murmur will log to the console (linux) or through message boxes (win32).
logfile=/var/log/murmur/murmur.log

# If set, murmur will write its process ID to this file.
pidfile=/var/run/murmur/murmur.pid

# The below will be used as defaults for new configured servers.
# If you're just running one server (the default), it's easier to
# configure it here than through D-Bus or Ice.
#
# Welcome message sent to clients when they connect
welcometext="<br />Welcome to <b>Sheltem's Server</b>.<br />May The Tartiflette Be With You<br />"

# Port to bind TCP and UDP sockets to
port=64738

# Specific IP or hostname to bind to.
# If this is left blank (default), murmur will bind to all available addresses.
host=XXX.XXX.XXX.XXX

# Password to join server
serverpassword=password

# Maximum bandwidth (in bits per second) clients are allowed
# to send speech at.
bandwidth=72000

# Maximum number of concurrent clients allowed.
users=30

# Regular expression used to validate channel names
# (note that you have to escape backslashes with \ )
#channelname=[ \\-=\\w\\#\\[\\]\\{\\}\\(\\)\\@\\|]+

# Regular expression used to validate user names

# Maximum length of text messages in characters, with image data. 0 for no limit.
#imagemessagelength=131072

# Allow clients to use HTML in messages, user comments and channel descriptions?
#allowhtml=true

# Murmur retains the per-server log entries in an internal database which
# allows it to be accessed over D-Bus/ICE.
# How many days should such entries be kept?
# Set to 0 to keep forever, or -1 to disable logging to the DB
#logdays=31

# To enable public server registration, the serverpassword must be blank, and
# this must all be filled out.
# The password here is used to create a registry for the server name; subsequent
# updates will need the same password. Don't lose your password.
# The URL is your own website, and only set the registerHostname for static IP
# addresses.
# Only uncomment the 'registerName' parameter if you wish to give your "Root" channel a custom name.
#
#registerName=Mumble Server
#registerPassword=secret
#registerUrl=http://mumble.sourceforge.net/
#registerHostname=

# To enable bonjour service discovery uncomment the following line.
# To change the name announced by bonjour adjust the registerName variable.
# See http://developer.apple.com/networking/bonjour/index.html for more information
# about bonjour.
#bonjour=True

# If you have a proper SSL certificate, you can provide the filenames here.
# Otherwise, Murmur will create it's own certificate automatically.
#sslCert=
#sslKey=

# If murmur is started as root, which user should it switch to?
# This option is ignored if murmur isn't started with root privileges.

# If this options is enabled, only clients which have a certificate are allowed
# to connect.
#certrequired=False

# You can configure any of the configuration options for Ice here. We recommend
# leave the defaults as they are.
# Please note that this section has to be last in the configuration file.

Ensuite on défini le mot de passe “superuser” (ce qui crée également le fichier de base de données de murmur) :

/usr/local/sbin/murmurd -ini /usr/local/etc/murmur.ini -supw password

On ajoute ça dans /etc/rc.conf :

murmur_enable="YES"

Tout simplement :

/usr/local/etc/rc.d/murmur start

La ligne qui va bien pour que pf laisse passer le traffic entre les clients (mumble) et le serveur (murmur) :

pass in on $ext_if proto { tcp udp } to ($ext_if) port 64738

$ext_if est une macro défini en début de fichier de configuration :

ext_if="re0"

ou re0 est à remplacer par le nom de l'interface réseau.
