NoCheatPlus

Detect and fight the exploitation of various flaws/bugs in Minecraft!

Features Permissions Commands Configuration Jenkins

Introduction

NoCheatPlus attempts to prevent cheat clients from exploiting weaknesses of Minecraft or its protocol, making your server more safe. Checks cover a wide range of issues including flying and speeding, fighting hacks, fast block breaking and nukers, inventory hacks, chat spam and other types of malicious behaviour. For a more complete list have a look at the Features Page.

NoCheatPlus puts emphasis on configurability and allows you to customize actions that are carried out when a player fails a check (e.g. silent cancelling, executing commands, just logging). Bypass permissions allow to control what check to apply for which players, all checks can be deactivated in the configuration, also having the option for world-specific configuration files. Many checks allow more detailed configuration to adjust sensitivity.

Certainly NoCheatPlus is not a magical bullet, it uses a lot of heuristics and even guessing, so you will encounter false positives here and there and also not catch every single violation. Example video of how NoCheatPlus blocks cheats (outdated plugin version).

NoCheatPlus was introduced by NeatMonster, building on the code base of NoCheat by Evenprime.

The following plugins might be useful to have a look at.

CompatNoCheatPlus (cncp)

Make plugins like mcMMO, Citizens, MagicSpells or MachinaCraft more compatbile with NoCheatPlus. Not all existing plugins are covered (yet), but you can leave a note or ticket request for cncp.

Orebfuscator

Orebfuscator fights all sorts of X-ray-hacks by altering the map information that is sent to the players, such that they have to mine blocks to actually reveal what is behind. Virtually a "must have".

    Apart from blockinteract.... you also have blockbreak checks of course (frequence, fastbreak, reach, direction). Which checks did you disable or can post/send your config for simplicity?

    I believe that quality stays better if NC+ keeps being free and open, since we get more feedback and reports, because of higher costumer count (those that don't have paypal etc.).
    If you feel our quality is currently lacking somewhere then feel free to report those quality issues or even push pull requests on our Github repository for quick fixing.

    @BrutalNetwork: Go

    Pretty much all interaction checks except speed protect against insane nukers:
    Visible - Prevents hackers from interacting with blocks they don't see
    Reach - Prevents from interacting with blocks out of their reach distance
    Direction - Forces to look at the block a hacker wants to interact with
    Good to know: Why did you disable the interaction checks? Where there some annoying bugs/issues with one of them?
    If yes feel free to open up a ticket and we will look closer at your issue.

    I stopped a heap of block interactions and i have had reports that nuker still works in our prison mines. Which setting stops this so i can just enable that one?

    You should, for better quality.

    @kristijan260393: Go

    Realistically i would rather enable donations or payed services if i needed it for survival mode. We still do have some basic cost for keeping hold of some domain and other, so donations or even some payed extras are not 100% off the table. Don't expect the core to become private too easily though...

    Good :), the logs might be lengthy, most interesting might be what happens just before logout and just after login, until/from first teleport(s).

    @asofold: Go

    Thank you. I will do more testing tomorrow on localhost.

    @kangarkooo: Go

    Do you have logs of log-out locations or are the log-in locations logged before AuthME teleports players?

    If you can reproduce it locally or with very few players online, you can add "debug: true" to the moving section of the config of NCP (or even above in the checks section), which could give more hints about what happens, but it'll spam the logs for each and every player, so it's usually not an option for production servers.

    @asofold: Go

    I have exact login loc. set to true, and I have enabled teleporting to spawn in AuthMe. After /login players are teleported back, but I am using sessions (12hours) and in my case player logged in time, so he wasn't teleported by authme.

    @kangarkooo: Go

    Do you have the bukkit.yml set to use exact login locations? Do you have a plugin enforcing login locations related to last logout (not suggesting to have one in general though)?
