Running an Anticheat on Pterodactyl or Shared Hosting

What limits does a panel host place on an anticheat?

A panel host such as Pterodactyl, or a shared Minecraft provider, usually controls the Java runtime, the startup command, the port allocation, and the memory limit. An anticheat needs write access to its plugin folder, a runtime that meets the server software's documented requirement, and enough memory for its own state. Confirm those four points before you buy a plan or install a plugin.

Which panel controls should you confirm first?

Panel names and layouts differ between hosts, so look for the function rather than a specific button. Write down each control and whether you can change it yourself.

• The Java image or runtime the server template uses, and whether you can select another one.
• The startup command, and whether it launches the server jar you expect.
• File manager or SFTP access to the plugins folder and to each plugin's data folder.
• Console access, including how far back the console history goes.
• The memory limit, and whether the panel restarts the server when it exceeds that limit.

How do you check the startup line before the first start?

Read the startup command in the panel before you start the server. A template can point at an old jar, add flags you did not expect, or set a memory range below what your server needs. Replace the placeholders below with your plan's values and keep any panel variables your template already uses.

java -Xms<min-memory> -Xmx<max-memory> -jar <server-jar> nogui

How much memory should the anticheat get?

The anticheat shares the server's heap, so a plan that fits the server alone may not fit it during a combat peak. Do not rely on a memory figure from a listing or a forum post. Load test on a staging copy of the same plan with a player count close to your busiest hour, then compare heap use with and without the anticheat.

If the panel restarts the server when memory spikes, check its resource graph and the log for an OutOfMemoryError before you blame the anticheat. A crash log and a panel restart can look identical from the player side.

Where does an anticheat fit behind a proxy?

Many panel plans run one backend behind a proxy, or several backends on one host. Install the anticheat on each backend that runs gameplay, not on the proxy alone. Check which backend your panel exposes as the game server, because a second backend on the same host can receive its own copy of the plugin folder and its own config.

How do you read logs when the console is limited?

Some panels show only recent console output. Download the log file from the file manager before you restart, so the failing start is not lost. The file to copy is usually logs/latest.log inside the server folder. Rename the copy with the date and the server build, then restart.

What should you ask a host before you buy?

Ask these questions in writing, then test the answers on a trial plan before you move a live network.

• Can I upload a .jar file through the file manager or SFTP, and can I edit files under plugins?
• Can I change the Java runtime, and which versions are offered?
• Does the host document its Java version and its kernel or container limits?
• Are automatic backups or snapshots taken of the plugin data folders, not only the world?
• Does a crash restart the server automatically, and is that restart logged?

Test on a copy before the live server

Clone the server on the same plan, install the anticheat and its PacketEvents dependency, and start it once with the exact startup line you plan to use. Confirm the plugin enables from the console, check the log for dependency errors, then run an alert-only window with testers before enforcement. Record the plan name, the Java runtime, and the memory limit in your change log.
