Mumble installation

Mumble is not available in the default Ubuntu repositories, so you have to add a new ppa repository first by typing:

sudo add-apt-repository ppa:mumble/release
sudo apt-get update

This will add mumble to your present repository and then update the repository.

If the above command does not work, then you may try the following:

sudo apt-get install mumble-server
sudo dpkg-reconfigure mumble-server

autobanAttempts, autobanTimeframe and autobanTime

In order to avoid clients from affecting the low-latency of other uers, mumble has a global-ban system,which can be configured using autobanAttempts, autobanTimeframe and autobanTime. If someone tries to connect to the server for X times in Y seconds they will be banned for Z seconds.

#autobanAttempts = 10
