Mumble is a free, open source, high quality, and low latency voice chat software. Primarily intended for gaming, it is also commonly used for recording podcasts and collaborating on software development (among others).
Downloads for various operating systems can be found on the Mumble website. For most Linux distributions, you can also just use your package manager:
sudo pacman -S mumble for Arch,
sudo apt install mumble for Debian, and so on. I've had numerous issues with Plumble on Android but I also know other people that are using it without any hitches ¯\_(ツ)_/¯ The best experience is on desktop.
Launch the application then go through the Audio Wizard. It will help you identify most issues and get them resolved before connecting to the server. Once that's finished, a dialogue should pop up prompting you to do just that. Click Add New..., enter
nixnet.services as the address, leave the port as default, enter the username you'd like to use, then give the server a friendly name with the Label box. You'll be able to quickly connect to the server again by clicking it as an option under
Mumble has a very odd way of granting different permissions to different users. This is done via the Access Control List (ACL).
The screenshot below shows the default permissions for all: everyone who joins the channel. There's also admin, auth, and whatever custom groups you create. The latter is where you add admins and mods.
Add then fill the
Group box in with some random (or predetermined) string such as
shoh5quei4moeTh7daigoh9ah. Enter this in the box like
#shoh5quei4moeTh7daigoh9ah. Set the permissions you want them to have (
Write ACL means they have full admin) then send the original string to the people you want administering or moderating. They'll need to put this in their Access Tokens which can be found in
Access Tokens. I also recommend having them register and go through the certificate wizard; this will ensure their username can't be taken by anyone else.
If you have
Write ACL permissions in a specific channel, you can then create subchannels within and build a hierarchy for different purposes. "Admins" typically have this permission but may be slightly restricted according what the parent channel's owner decides. Personally, I create a subchannel for some purpose and give the person requesting the channel the
Write ACL permission so they can do what they will with it from then on; its their space to use as they see fit.
If you're having issues, let me know, we'll get it resolved, and I'll add the problem/solution here.
