AMP Game Servers – User Guide

AMP (Application Management Panel by CubeCoders) is our self-service panel for running game servers (Minecraft, Valheim, Terraria, CS2, Factorio, … over 100 games). Any Base48 member with an SSO account can log in, create a server, and manage it from the browser.

This is a trust-based setup: everyone who logs in has full admin rights over the whole panel. See the common rules below. They're short.

Quick facts

Panel URL	http://amp.at.base48.cz
Login	Base48 Keycloak SSO (your normal Base48 account)
Server address for games	`amp.at.base48.cz` (or `10.48.0.130`) + your server's game port
Reachable from	The Base48 network (wifi / LAN / VPN)
Shared resources	16 CPU cores, 32 GB RAM, ~500 GB disk, shared by everyone
Admin contact	Infra admins – see AMP/Infrastructure

1. Logging in

Open http://amp.at.base48.cz while you are on the Base48 network.
- Use this hostname, not the IP. SSO login only works with the hostname.
Click Base48 Keycloak SSO.
Log in with your Base48 account. On your first login, AMP creates your user for you.
You land on the Instances screen. It lists every game server on the box.

Trouble logging in?

No admin menus / "Access denied" errors: log out (your name, top right → Logout) and log in again. AMP only reads your permissions when you log in.
AMP logs you straight back in as the old session: use a private/incognito window.
The page doesn't load: check you are on the Base48 network.

2. Creating a game server

On the Instances screen, click Create Instance (the + button).
Choose the Application (e.g. Minecraft Java Edition, Valheim, Terraria …).
Set a Friendly Name that starts with your nickname, e.g. pepa-minecraft. Everyone can then see whose server it is.
Leave the IP binding and ports on their defaults unless you know you need something else. AMP picks free ports automatically.
Click Create Instance. AMP downloads the game server (this can take a few minutes for Steam games) and starts it.
When the instance shows as running, click it to open its own management panel.

3. Connecting to your server

Open your instance → Status page (or Configuration → Server and Ports).
Note the game port (e.g. Minecraft: 25565).
In the game, connect to amp.at.base48.cz:PORT (or 10.48.0.130:PORT).

Examples:

Minecraft Java: amp.at.base48.cz:25565
Valheim: amp.at.base48.cz:2456

Servers are reachable from the Base48 network only. If you need a server reachable from the internet, ask an infra admin (it needs a port forward).

4. Managing your server

Click your instance in the Instances list to open it. The main pages are:

Page	What it's for
Status	Start / Stop / Restart / Update buttons, CPU/RAM usage, player count
Console	Live server log and a command line (e.g. Minecraft `op pepa`, `whitelist add …`)
Configuration	Game settings (difficulty, max players, world name, password, game version …)
File Manager	Browse, upload and download files (worlds, mods, plugins, configs). Supports drag & drop and zip extraction.
Backups	Take a backup now, restore one, download it
Schedule	Automatic tasks, e.g. a nightly backup, a daily restart, or auto-updates
Users / Players	Online players, kick/ban, whitelist

Common tasks

Update the game server: Status → Update (stop the server first). For Minecraft, change the version under Configuration → Minecraft → Server Type / Version, then click Update.

Install mods / plugins / a modpack: Minecraft: Configuration → Minecraft to pick Forge / Fabric / Paper, or use the built-in modpack installer. Otherwise, upload jars into mods/ or plugins/ with the File Manager.

Upload an existing world: Stop the server → File Manager → upload a zip → right-click → Extract → set the world name in Configuration → Start.

Make a backup before you change something risky: Backups → Take Backup. Restoring overwrites the current files.

Make it start automatically when the box reboots: On the main Instances screen, open your instance's menu and enable Start on boot.

Let a friend manage your server: Everyone can already manage every server. Just tell them which one is yours.

Delete your server: Stop it → on the Instances screen click the trash icon on your instance. This deletes all its files and backups. Download a backup first if you want to keep the world.

Common rules

Your servers, your rules – YOLO them. If you know what you're doing, you can do pretty much anything that's beneficial for the hackerspace. Take whatever resources you need.

Your own servers: do whatever you want. Experiment, break things, rebuild.
Other people's servers: leave them alone unless the owner is OK with it. Name yours nick-something so everyone knows whose it is.
Core panel stuff (SSO/login, users & roles, network settings of the main panel): go ahead if you know what you're doing. A broken login locks everyone out, though. If you change something there, tell the infra admins or note it on AMP/Infrastructure.
Clean up after yourself: delete servers you've abandoned.
Members' rules apply: nothing illegal.

FAQ

I don't see admin menus or I get "Access denied": Log out and log back in via SSO. If it still happens, ask an infra admin.

Can I use SFTP / FileZilla / WinSCP?

Yes, with an SSH key (SSO accounts have no AMP password, so password login won't work):

Click your name (top right) to open your profile and add your SSH public key (e.g. the contents of ~/.ssh/id_ed25519.pub). No key yet? Run ssh-keygen -t ed25519.
Find your instance's SFTP port: open the instance, go to its settings and search for "SFTP". Each server has its own port, e.g. 2224.
Connect with your SFTP client to amp.at.base48.cz on that port, using your AMP username (shown top right) and your private key.
You land in that instance's files.

For quick changes, the built-in File Manager in the browser also works.

My server won't start: Check the Console for the error. Common causes: port already used by another server (pick another port in Configuration), wrong Java/game version, not enough RAM set for a modpack.

Is my world backed up automatically?: Yes, daily, as part of the whole box. The whole AMP container is backed up every day. Restoring it rolls back everyone's servers, so it's only for disasters, not for undoing your own mistakes. Ask an infra admin if you need something from it.; Per-server backups are coming soon. Until then, if you want your own restore point, use Backups → Take Backup (and/or a daily backup under Schedule), especially before risky changes.

Can I run something that isn't a game?: Yes, run whatever you want, no need to ask. Besides games, AMP has some non-game apps, and the Generic application lets you run pretty much any program as a managed server.
