Types of servers for Mumble

Mumble is an open source VoIP software that allows us to create our own Mumble server on our PC or on other devices that consume less resources such as a NAS Synology, a Router with Open WRT or DD-WRT system, a Raspberry PI or a PC with limited resources or that has become old. 

This program runs as a client and needs to connect to a server that would be the meeting point for all users, as if you meet someone somewhere , with the option to create rooms and have different chats open for example, no interfere in the enemy's conversations if we are playing a gang of friends against each other.

If we choose an official Mumble server we can control many aspects such as server administrator, welcome messages, users, see who is connected, we can even create a common fund to pay for the maintenance of the server together . If we choose our own server either on our PC or on other devices, we will have the security of having our data safely and without paying extra to maintain it .

How to create a Mumble server on your pc with Murmur

When installing Mumble , it offers us the possibility of installing a software called Murmur , this is used to create your own Mumble server on the PC where you have it installed. In this way you can host the server on your own PC, the negative point of this Mumble server software is that it does not support configuration through a graphical interface .

In order to mount the Mumble server on your own PC with Murmur, we must follow these steps:

  1. First of all, make sure that you have installed Murmur together with Mumble , if you did not do it in its day, it is best that you take the opportunity to uninstall the version you have and install the new version together with Murmur.
  2. Look in the Murmur magnifying glass and click.

Simply with this, we will have the utility running that will turn our PC into a private Mumble server for free.

Things change when we want to make any changes to the server, for this we will have to edit the configuration file by hand with a text editor  since it lacks a graphical interface. The file to edit is called murmur.ini and we can find it in the folder c: \ Program Files (x86) \ Mumble . Make sure to stop the server before configuring , now you can change it by opening this file with an editor and we change the necessary configuration, we only have to save and run Murmur again .

Another interesting option for Mumble is that in addition to being able to use Murmur to turn your PC into a Mumble server, with uMurmur we can create a server without depending on our PC on devices with few resources , for example, on a NAS like those of Synology, Router that have an open WRT or DD-WRT system, on old PC's or limited in resources or even on a Raspberry PI.

We just have to install the uMurmur software on the hardware that we are going to use as a server, either on a Router with open WRT or DD-WRT system , on a Raspberry Pi with Raspbian, on a PC with limited resources running Linux, and on If you want to install it on the Synology NAS, we will have to download it from the Package Center in DSM , in the Community Packages section.

Similarly, in both Router and Raspbian or Linux, we must edit the configuration file with an editor and change the settings manually, in the case of NAS Synology, the way to edit the configuration file is done with a program called Config File editor.

The main options to modify in the configuration file are:

  • Welcome message , every time you connect to the Murmur server the server receives us with a welcome message, we simply have to look for the welcometext variable and change the default message to the phrase we want to receive users every time connect to our server.

  • Access password , to avoid unwanted access to our private server, you can protect it with a password that it will ask for when we want to connect to the server. To configure a password we look for the variable serverpassword and after the = we add the password .

  • Port for the server , we can configure the port that we are going to use in the Mumble server if the one that comes by default does not seem correct. The default port is 64738 and we can change it by looking for the port variable in the configuration file and adding the chosen port after the equal.

  • Simultaneous connections , as we saw in the official Mumble server, we can select a series of Slots or simultaneous Users , in the server that we are going to configure we can also assign a maximum number of simultaneous users, for this we look for the users variable and assign the value of maximum users after the equal .

  • Bandwidth , we can establish the maximum bandwidth that the server will use, so you can control the bandwidth you want to allocate to this and balance the available services in case you have any more, also not to assign all the bandwidth available in case it is the only service. The bandwidth is assigned in bits per second , we must look for the bandwidth variable and put the value after the = , for 72000 which is by default it would be about 7.2 Mb / s maximum, but everything will depend on your internet connection .

  • Auto Ban of users , in this case we can assign a maximum number of failed connection attempts in a period of time and in this case make a ban to the user . We will have to search autobanAttempts for the number of failed connections, autobanTimeframe for the time period of failed attempts, and  autobanTime to set the ban time. If they are commented with # we must remove them for this option to work.

Remember to restart the server after the changes made.


If you have a Raspberry Pi in the drawer, an abandoned or modest configuration PC, a router compatible with Open WRD or a Synology NAS, you can use it to configure your own server with Murmur , having the security of having the data on your own server  and totally free .

In OkayGotcha we have a server mounted with uMurmur on a Synology NAS and it has been configured and working correctly for a long time, you just have to do the initial configuration and forget about it , to enjoy the games with all the advantages of maintaining your own server at home.
