Mumble - Open Source VOIP Client and Server

Mumble, a new Open Source version for all those VoIP lovers.

You can find the website here

I am a bit new to this program, but found it very easy to install. Once people discover Mumble I am sure we can add to the How-To, please see the forum site.

Install Program Tools

SSH logon

You can pickup WinSCP here;

Putty here; This all could be done via Putty too if you want.

Get the latest version of Mumble Here Download here

Please note the download is LZMA format, but can be opened with WinRAR, but I am sure all you Linux experts will have something better! :-D

Install Mumble

Create a new user within the Webgui

User:       mum
Name:       Mumble
Last Name:  Server 

Everything else is up to you, but don’t give it access to anything

Logon to you ClearOS box via SSH

Go: /home/mum

Copy the murmur-static_x86-version.tar.lzma file into this directory

Command chown mum:allusers murmur-static_x86-version.tar.lzma
Update: Please provide a CLI command to open this file??? 

You can delete the zip file if you like

Type:  chown -R mum:allusers /home/mum/server
Type:  chmod -R 0755 /home/mum/server

I changed the folder name to server from murmur-static_x86-version to make it a bit easier.

Next, edit the .ini file

The murmur.ini file located under;


Here is where you can store the password for users, name of the server, etc.

Here is .ini File, since this is different than Ventrilo or TS, you can modify this as you like. I have indicated areas that you need to change for this How-To, but you'll need to change them to your liking;

 # Path to database. If blank, will search for
 # murmur.sqlite in default locations or create it if not found.
 # 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.
 # 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.
 # Alternate service name. Only use if you are running distinct
 # murmurd processes connected to the same D-Bus daemon.
 # 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 -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 conntection, and
 # any script attempting to access must then have this secret.
 # 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).
 # If set, murmur will write its process ID to this file.
 # 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
Welcome to this server running Murmur.
Enjoy your stay!

If you have any input on how to setup the ini files, please direct it to the forum site.

From what I know Mumble has no limitation.

Modifying your Script File

Next will be to create script file so you can load the service from CLI or later in the webgui.

You need to run the service in order for it to create some files, including the .log file.

Copy the text below into a script file

Location of the file


Name the script file


Enter the following information into the script file.

You can do this many ways, either by nano in the CLI (Command Line Interface) or use WinSCP to create the edit the file.

Yes, I used a modified ventrilo script again. Hey I like seeing the little green “OK” when my server starts!

# Mumble This shell script takes care of starting and stopping
# the Mumble subsystem (Mum).
# chkconfig: - 90 10
# description: Mumble Chat Interface.
# processname: mum
# config: /do_not_remove/murmur.ini
# pidfile: /do_not_remove/
# Source function library.
. /etc/rc.d/init.d/functions

prog="Mumble Server"
vent_path=/home/mum/server				# <----  Replace with the path to your /ventsrv directory
vent_user=mum						# <----  Replace with sudo user
# Startup ventrilo servers.
sudo -u $vent_user $vent_path/$vent_server
if [ $ret -eq 0 ]; then
while [ $STARTTIMEOUT -gt 0 ]; do
RESPONSE=`ls -al 2>&1` && break
echo "$RESPONSE" | grep -q "root" && break
sleep 1
if [ $STARTTIMEOUT -eq 0 ]; then
echo "Timeout error occurred trying to start $prog Daemon."
action $"Starting $prog: " /bin/false
action $"Starting $prog: " /bin/true
action $"Starting $prog: " /bin/false

return $ret
VENTPID=`cat "$vent_pid" 2>/dev/null `
if [ -n "$VENTPID" ]; then
/bin/kill "$VENTPID" >/dev/null 2>&1
if [ $ret -eq 0 ]; then
while [ $STOPTIMEOUT -gt 0 ]; do
/bin/kill -0 "$VENTPID" >/dev/null 2>&1 || break
sleep 1
if [ $STOPTIMEOUT -eq 0 ]; then
echo "Timeout error occurred trying to stop $prog Daemon."
action $"Stopping $prog: " /bin/false
action $"Stopping $prog: " /bin/true
action $"Stopping $prog: " /bin/false
action $"Stopping $prog: " /bin/false
return $ret

# See how we were called.
case "$1" in
status vent
echo $"Usage: $0 {start|stop|status|restart}"
exit 1

Copy the same text above into a file and put it under

Type:  chown -R mum:allusers /etc/rc.d/init.d/mum
Type:  chmod +xw /etc/rc.d/init.d/mum
Type: chkconfig --add mum
Type: chkconfig --levels 345 mum on && chkconfig --list mum

Now you can start your server

Type: service mum start

If the service does start. You make need to modify the mum file be executable.  You can do this by this command. 
chmod +xw /etc/rc.d/init.d/mum

“chmod: cannot access `/home/mum/server/murmur.log': No such file or directory”

ignore it, because the file is not there, as you just created it. Then you should see the system come back as “OK” in green.

service mum restart
service mum stop

Almost Done

Next we need to create a link file under the /var/log so we can view it via the webgui.

Type: mkdir /var/log/mum
Type: cd /home/mum/server/
Type: cp murmur.log /var/log/mum/murmur.log
Type: rm murmur.log 
then Y
Type: chown -R mum:allusers /var/log/mum/murmur.log
Type: ln -s /var/log/mum/murmur.log murmur.log

Now restart the webconfig service

Type: service webconfig restart 

Now you should be able to access your log menu and see


Next we'll want to add the necessary changes to the webgui in order to see the server as a service.

You need to locate the following file.


And insert this line.

"mum"     => array("httpd",        "murmur.x86",     "no",  "Mumble Chat Server",     "no",  null),

Restart the webconfig

Type:  service webconfig restart

You should be all done!!!
