How to choose
Most people want one of two things. If you want a permanent box that runs all your servers and never gives you a bill surprise, get Contabo. If you want to dial in the lowest latency to a specific region, or only need a server for a few nights at a time, get Kamatera.
| Contabo | Kamatera |
| Best for | Permanent all in one | Region tuning, temp box |
| Price per GB | better | ok |
| Billing | monthly | hourly |
| Config | tiers | exact |
| Regions | several | 13 |
| Sweet spot plan | 4 vCPU / 6 GB / 400 GB | 1 vCPU / 1 GB / NVMe |
| Good for Mumble + TS3 + TS6 | one box, yes | upgrade RAM first |
| Free trial | no | 30 days |
right size it
Mumble and TeamSpeak 3 each idle around 20 to 40 MB of RAM. TeamSpeak 6 sits closer to 120 MB at idle plus chat history. A 1 GB Kamatera box handles Mumble and TS3 side by side. Move to 2 GB once you also run TS6 and a web server on the same box.
Once the box is up
First login checklist, then pick a guide:
01 first login
SSH in and update
root@voice-host:~$ apt update && apt upgrade -y
02 basics
Add a non root user and lock SSH
Create a sudo user, move your SSH key over, then disable password login in /etc/ssh/sshd_config (set PasswordAuthentication no) and restart sshd. Keep root login off.
03 firewall
Turn UFW on and open only what you need
root@voice-host:~$ ufw default deny incoming
root@voice-host:~$ ufw allow 22/tcp
root@voice-host:~$ ufw --force enable
Only open the voice ports after the server is installed. See each guide for the exact list.
04 install
Follow a server guide
Pick one and run it. Each takes about ten minutes after the box is clean.
