Description: | |
Hello, | |
I **HATE** Discord. | |
Discord users keep telling about their so called **discord server**, | |
which is | |
not dedicated to them at all. And Discord has a very bad quality and a | |
lot of | |
voice distorsion. | |
Why not run **your very own mumble server** with high voice quality and | |
low | |
latency and privacy respect? This is very easy to setup on OpenBSD! | |
Mumble is an open source voip client, it has a client named Mumble | |
(available | |
on various operating system) and at least Android, the server part is | |
murmur | |
but there is a lightweight server named umurmur. People authentication | |
is done | |
through certificate generated locally and automatically accepted on a | |
server, | |
and the certificate get associated with a nickname. Nobody can pick the | |
same | |
nickname as another person if it's not the same certificate. | |
### How to install? | |
# pkg_add umurmur | |
# rcctl enable umurmurd | |
# cp /usr/local/share/examples/umurmur/umurmur.conf /etc/umurmur/ | |
We can start it as this, you may want to tweak the configuration file | |
to add a | |
password to your server, or set an admin password, create static | |
channels, | |
change ports etc.... | |
You may want to increase the `max_bandwidth` value to increase audio | |
quality, | |
or choose the right value to fit your bandwidth. Using umurmur on a DSL | |
line is | |
fine up to 1 or 2 remote people. The daemon uses very little CPU and | |
very | |
little memory. Umurmur is meant to be used on a *router*! | |
# rcctl start umurmurd | |
If you have a restrictive firewall (I hope so), you will have to open | |
the ports | |
TCP and UDP 64738. | |
### How to connect to it? | |
The client is named Mumble and is packaged under OpenBSD, we need to | |
install it: | |
# pkg_add mumble | |
The first time you run it, you will have a configuration wizard that | |
will take | |
only a couple of minutes. | |
Don't forget to set the sysctl kern.audio.record to 1 to enable audio | |
recording, as OpenBSD did disable audio input by default a few releases | |
ago. | |
You will be able to choose a push-to-talk mode or voice level to | |
activate and | |
quality level. | |
Once the configuration wizard is done, you will have another wizard for | |
generating the certificate. I recommend choosing "Automatically create | |
a | |
certificate", then validate and it's done. | |
You will be prompted for a server, click on "Add new", enter the name | |
server so | |
you can recognized it easily, type its hostname / IP, its port and your | |
nickname and click OK. | |
Congratulations, you are now using your own private VOIP server, for | |
real! |
