Murmur - The Mumble Server

Setting up a Mumble server (called Murmur) on Debian is fairly straightforward. Here's a step-by-step guide to get you up and running:

✅ Step 1: Update Your System

sudo apt update && sudo apt upgrade -y

✅ Step 2: Install Murmur

sudo apt install mumble-server -y

This will install both the server (murmurd) and the client (mumble)—but you only need the server part unless you're also connecting from the same machine.

✅ Step 3: Configure Murmur

Edit the Murmur configuration file:

sudo nano /etc/mumble-server.ini

Look for and adjust these key settings:

• welcometext: Set a welcome message for users.
• port: Default is 64738, change if needed.
• serverpassword: Set this if you want the server to be password-protected.
• bandwidth: Optional, but can limit bandwidth per user.
• registerName: Optional, set the server's name on the public server list.
• username: Usually set to mumble-server (default user it runs under).

✅ Step 4: Start and Enable Murmur

sudo systemctl enable --now mumble-server

Check the status:

sudo systemctl status mumble-server

✅ Step 5: Set the SuperUser Password

Run the following command to set the admin ("SuperUser") password:

sudo dpkg-reconfigure mumble-server

This will launch a prompt asking if you want to run it as a service and set the SuperUser password.

Alternatively, you can run:

sudo murmurd -ini /etc/mumble-server.ini -supw NEWPASSWORD

Replace NEWPASSWORD with your desired password.

✅ Step 6: Open Firewall (if applicable)

If using ufw:

sudo ufw allow 64738/tcp

sudo ufw allow 64738/udp

sudo ufw reload

✅ Step 7: Connect with a Mumble Client

1. Download the Mumble client from https://www.mumble.info.
2. Open it and add a new server:
   • Address: your server's IP or domain
   • Port: 64738
   • Username: whatever you like
   • Password: leave blank unless you set one

To log in as the admin user:

• Use username: SuperUser
• Use the password you set earlier

🔐 Optional: Enable SSL/TLS (for secure connection)

This is optional as Murmur already uses TLS by default. You can manage this in the mumble-server.ini config file if you're setting up custom certificates.
