Mumble
Mumble is a free voice chat server. While not as flashy as TeamSpeak, it has all the functionality and is easier to customize. And it is better. I may be slightly biased.
Note
Note that this guide assumes that you have installed Auth with the official :doc:/installation/allianceauth
guide under /home/allianceserver
and that it is called myauth
. Accordingly, it assumes that you have a service user called allianceserver
that is used to run all Auth services under supervisor.
Warning
This guide is currently for Ubuntu only.
Bare Metal Installations
Installing Mumble Server
The mumble server package can be retrieved from a repository, which we need to add:
sudo apt-add-repository ppa:mumble/release
sudo apt-get update
Now three packages need to be installed:
sudo apt-get install python-software-properties mumble-server libqt5sql5-mysql
Installing Mumble Authenticator
Next, we need to download the latest authenticator release from the authenticator repository.
git clone https://gitlab.com/allianceauth/mumble-authenticator /home/allianceserver/mumble-authenticator
We will now install the authenticator into your Auth virtual environment. Please make sure to activate it first:
source /home/allianceserver/venv/auth/bin/activate
Install the python dependencies for the mumble authenticator. Note that this process can take 2 to 10 minutes to complete.
pip install -r requirements.txt
Configuring Mumble Server
The mumble server needs its own database. Open an SQL shell with mysql -u root -p
and execute the SQL commands to create it:
CREATE DATABASE alliance_mumble CHARACTER SET utf8mb4;
GRANT ALL PRIVILEGES ON alliance_mumble . * TO 'allianceserver'@'localhost';
Mumble ships with a configuration file that needs customization. By default, it’s located at /etc/mumble-server.ini
. Open it with your favorite text editor:
sudo nano /etc/mumble-server.ini
We need to enable the ICE authenticator. Edit the following:
icesecretwrite=MY_CLEVER_PASSWORD
, obviously choosing a secure passwordensure the line containing
Ice="tcp -h 127.0.0.1 -p 6502"
is uncommented
We also want to enable Mumble to use the previously created MySQL / MariaDB database, edit the following:
uncomment the database line, and change it to
database=alliance_mumble
dbDriver=QMYSQL
dbUsername=allianceserver
or whatever you called the Alliance Auth MySQL userdbPassword=
that user’s passworddbPort=3306
dbPrefix=murmur_
To name your root channel, uncomment and set registerName=
to whatever cool name you want
Save and close the file.
To get Mumble superuser account credentials, run the following:
sudo dpkg-reconfigure mumble-server
Set the password to something you’ll remember and write it down. This is your superuser password and later needed to manage ACLs.
Now restart the server to see the changes reflected.
sudo service mumble-server restart
That’s it! Your server is ready to be connected to at example.com:64738
Configuring Mumble Authenticator
The ICE authenticator lives in the mumble-authenticator repository, cd to the directory where you cloned it.
Make a copy of the default config:
cp authenticator.ini.example authenticator.ini
Edit authenticator.ini
and change these values:
[database]
user =
your allianceserver MySQL userpassword =
your allianceserver MySQL user’s password
[ice]
secret =
theicewritesecret
password set earlier
Test your configuration by starting it:
python /home/allianceserver/mumble-authenticator/authenticator.py
And finally, ensure the allianceserver user has read/write permissions to the mumble authenticator files before proceeding:
sudo chown -R allianceserver:allianceserver /home/allianceserver/mumble-authenticator
The authenticator needs to be running 24/7 to validate users on Mumble. This can be achieved by adding a section to your auth project’s supervisor config file like the following example:
[program:authenticator]
command=/home/allianceserver/venv/auth/bin/python authenticator.py
directory=/home/allianceserver/mumble-authenticator
user=allianceserver
stdout_logfile=/home/allianceserver/myauth/log/authenticator.log
stderr_logfile=/home/allianceserver/myauth/log/authenticator.log
autostart=true
autorestart=true
startsecs=10
priority=996
In addition, we’d recommend adding the authenticator to Auth’s restart group in your supervisor conf. For that, you need to add it to the group line as shown in the following example:
[group:myauth]
programs=beat,worker,gunicorn,authenticator
priority=999
To enable the changes in your supervisor configuration, you need to restart the supervisor process itself. And before we do that, we are shutting down the current Auth supervisors gracefully:
sudo supervisor stop myauth:
sudo systemctl restart supervisor
Configuring Auth
In your auth project’s settings file (myauth/settings/local.py
), do the following:
Add
'allianceauth.services.modules.mumble',
to yourINSTALLED_APPS
listset
MUMBLE_URL
to the public address of your mumble server. Do not include any leadinghttp://
ormumble://
.
Example config:
# Installed apps
INSTALLED_APPS += [
# ...
'allianceauth.services.modules.mumble'
# ...
]
# Mumble Configuration
MUMBLE_URL = "mumble.example.com"
Finally, run migrations and restart your supervisor to complete the setup:
python /home/allianceserver/myauth/manage.py migrate
supervisorctl restart myauth:
Permissions
To use this service, users will require some of the following.
Permission |
Admin Site |
Auth Site |
---|---|---|
mumble.access_mumble |
None |
Can Access the Mumble Service |
ACL configuration
On a freshly installed mumble server only your superuser has the right to configure ACLs and create channels. The credentials for logging in with your superuser are:
user:
SuperUser
password: what you defined when configuring your mumble server
Optimizing a Mumble Server
The needs and available resources will vary between Alliance Auth installations. Consider yours when applying these settings.
Bandwidth
https://wiki.mumble.info/wiki/Murmur.ini#bandwidth This is likely the most important setting for scaling a Mumble installation, The default maximum Bandwidth is 72000bps Per User. Reducing this value will cause your clients to automatically scale back their bandwidth transmitted, while causing a reduction in voice quality. A value that’s still high may cause robotic voices or users with bad connections to drop due entirely due to the network load.
Please tune this value to your individual needs, the below scale may provide a rough starting point.
72000
- Superior voice quality - Less than 50 users.
54000
- No noticeable reduction in quality - 50+ Users or many channels with active audio.
36000
- Mild reduction in quality - 100+ Users
30000
- Noticeable reduction in quality but not function - 250+ Users
Forcing Opus
https://wiki.mumble.info/wiki/Murmur.ini#opusthreshold A Mumble server, by default, will fall back to the older CELT codec as soon as a single user connects with an old client. This will significantly reduce your audio quality and likely place a higher load on your server. We highly recommend setting this to Zero, to force OPUS to be used at all times. Be aware any users with Mumble clients prior to 1.2.4 (From 2013…) Will not hear any audio.
opusthreshold=0
AutoBan and Rate Limiting
https://wiki.mumble.info/wiki/Murmur.ini#autobanAttempts.2C_autobanTimeframe_and_autobanTime The AutoBan feature has some sensible settings by default. You may wish to tune these if your users keep locking themselves out by opening two clients by mistake, or if you are receiving unwanted attention
https://wiki.mumble.info/wiki/Murmur.ini#messagelimit_and_messageburst This, too, is set to a sensible configuration by default. Take note on upgrading older installs, as this may actually be set too restrictively and will rate-limit your admins accidentally, take note of the configuration in https://github.com/mumble-voip/mumble/blob/master/scripts/murmur.ini#L156
“Suggest” Options
There is no way to force your users to update their clients or use Push to Talk, but these options will throw an error into their Mumble Client.
https://wiki.mumble.info/wiki/Murmur.ini#Miscellany
We suggest using Mumble 1.4.0+ for your server and Clients, you can tune this to the latest Patch version.
suggestVersion=1.4.287
If Push to Talk is to your tastes, configure the suggestion as follows
suggestPushToTalk=true
General notes
Setting a server password
With the default configuration, your mumble server is public. Meaning that everyone who has the address can at least connect to it and might also be able to join all channels that don’t have any permissions set (Depending on your ACL configured for the root channel). If you want only registered member being able to join your mumble, you have to set a server password. To do so open your mumble server configuration which is by default located at /etc/mumble-server.ini
.
sudo nano /etc/mumble-server.ini
Now search for serverpassword=
and set your password here. If there is no such line, add it.
serverpassword=YourSuperSecretServerPassword
Save the file and restart your mumble server afterward.
sudo service mumble-server restart
From now on, only registered member can join your mumble server. Now if you still want to allow guests to join, you have two options.
Allow the “Guest” state to activate the Mumble service in your Auth instance
Enabling Avatars in Overlay (V1.0.0+)
Ensure you have an up-to-date Mumble-Authenticator. This feature was added in V1.0.0
Edit authenticator.ini
and change (or add for older installations) This code block.
;If enabled, textures are automatically set as player's EvE avatar for use on overlay.
avatar_enable = True
;Get EvE avatar images from this location. {charid} will be filled in.
ccp_avatar_url = https://images.evetech.net/characters/{charid}/portrait?size=32
