JoinJail

Do you find that the whitelist does not work properly when playing in offline mode? JoinJail creates a small bedrock jail very very very far away from spawn and players spawn inside of it when joining and can only leave when using the set password.

About this Mod

JoinJail

JoinJail was made to create a sort of password protected server.
We found that running a Minecraft server in offline mode made our whitelist not work properly. So I made this mod.

This mod generates a bedrock jail / holding place very very very far away from spawn. The only way to leave the jail is by using the set password. If a user dies in the jail they will spawn outside the jail but the first tick after spawning they will be back in the jail.

Usage

If you join a server with this mod you are required to enter the set password, this is done with the command:

/joinjail

/joinjail is the command and should be followed by the set password. If correct, you will be added to the whitelist and you can now always join.

Commands

  • /joinjail setPassword
    • This will set a new password
  • /joinjail ban
    • This will ban the selected player with the given reason. (This can be undone with the regular /pardon command)

Config

In the Minecraft config folder there will be the JoinJail folder. In here you will have the whitelist and password files

  • whitelistfile.txt
    • this list contains the list of players whitelisted
  • password.txt
    • this file contains the password that is needed to join the server.

Frequently Asked Questions

JoinJail server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20). You can switch loaders with one click in the panel.

Is JoinJail compatible with fabric?

JoinJail officially supports fabric for Minecraft 1.20, 1.19.4, 1.19.3. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with JoinJail – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if JoinJail consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
