what is great about mumble: clients exist for Windows, OSX, (at least Debian/Ubuntu) Linux and even Android and IPhone.

the audio quality is SUPERB (better than phone) if you use good headphones like sennheiser

a disadvantage is the reverb that mumble can not cancel.

IMHO if your server / clients is not hacked… it is assumed private and encrypted.

it is a little confusing:

murmur = server
mumble = desktop client
plumble = android mobile client

it is highly advised to use headphones or headsets! (reverb!)

it is basically very simple to start mumble-server (murmur) on your qnap nas. (atom cpu)

ssh into your qnap then download murmur from sourceforge:

wget http://downloads.sourceforge.net/project/mumble/Mumble/1.2.3/murmur-static_x86-1.2.3.tar.bz2?r=http%3A%2F%2Fmumble.sourceforge.net%2F&ts=1360361431&use_mirror=freefr


bunzip2 murmur-static_x86-1.2.3.tar.bz2
tar fxv murmur-static_x86-1.2.3.tar

cd murmur-static_x86-1.2.3
vim murmur.ini
-> make shure to set password + uncommend



levae the last thing blank if you want a public server.

then make also shure that the mumble typical port is open: 64738

then simply start it:


and exit from the shell. (it will keep running even without nohup)
