From Wikipedia, the free encyclopedia:

Mumble is a voice over IP (VoIP) application primarily designed for use by gamers, similar to programs such as TeamSpeak and Ventrilo.

This page goes over installation and configuration of both the client portion of the software (Mumble) and the server portion (Murmur).



Install mumble from the official repositories, or mumble-gitAUR from AUR.

For JACK support, install mumble-jackAUR, or mumble-jack-gitAUR from AUR.


When you first launch the client, a configuration wizard will take you through the setup process. Settings can be changed later through the menu.

For a discussion of advanced settings, see the official documentation. The Mumbleguide is a good starting point.


The Mumble project maintains a good guide for setting up the server here: Murmurguide. What follows is a quick-and-dirty, abridged version of that guide.


Install murmur from the official repositories.

The postinstall script will tell you to reload dbus and set the supervisor password. The default configuration doesn't use dbus, so you can ignore that if you want. Setting the supervisor password is recommended, however.



If you use a firewall, you will need to open TCP and UDP ports 64738. Depending on your network, you may also need to set a static IP, port forwarding, etc.

Config File

The default Murmur config file is at /etc/murmur.ini and is heavily commented. Reading through all the comments is highly recommended.


Enable and then start Murmur with systemctl enable murmur and systemctl start murmur. If all went smoothly, you should have a functioning Murmur server.

Self-Signed Certificate

Reason: Not sure if this works when reverse lookups don't work properly. (Discuss in Talk:Mumble#)

By default, murmur will generate a default self-signed certificate. Clients connecting to the server will warn users about the host name not matching and the certificate being untrusted. If your server is in DNS, you can get rid of the hostname mismatch by creating your own self-signed certificate.

Create a secure directory for the certificate and key to live in and switch to it.

mkdir /var/lib/murmur/ssl
chmod 700 /var/lib/murmur/ssl
chown murmur.murmur /var/lib/murmur/ssl
cd /var/lib/murmur/ssl

Generate a private key for your server:

openssl genrsa -des3 -out 1024

create a certificate sign request and strip the password from your private key

openssl req -new -key -out
openssl rsa -in -out

self-sign with your CSR a new server certificate for your mumble server

openssl x509 -req -days 365 -in -signkey -out

Edit murmur.ini and tell it where your key and cert is:
