NoCheatPlus

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

Main 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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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".

    @asofold: Go

    So if I installed the Spigot 1.8 protocol hack then there would be no problems?

    @DanSpedey: Go

    No and somewhat. We don't use UUIDs for storing player data (yet), however the history/data of NCP is only kept until restart, so the risks that name changing pose are strongly limited. The actions can already now be changed to use [uuid] instead of [player], if desired, though the player name should be correct while the player is online.

    Does it support UUIDs yet?

    @KevinEssence: Go

    Currently yes (fixes for passable). I will upload it soon.

    @Chris_GSPvP: Go

    Please make a ticket and/or describe more what the bow has to do with it? So far i understand someting with moving with a bow and getting set back. Is it... you pull the string of your bow and after releasing or firing, you can't move on normally, despite not pulling the string anymore? We also could use a glimpse at the output of the "ncp version" command...

    Concerning fences: We don't enforce moving speed vs. eating.

    @andrewcramer: Go

    Could you give more details on "knock somebody off something 3 times with knockback enchantment"? Specifically:

    • Output of the "ncp version" command.
    • What level of knockback is involved? Does it happen on from the lowest?
    • What is three times? How fast succession? Is the hit player moving or freezing on the side of the attacking player?
    • Does it happen to all players for either side (attacker, defender who gets set.back)? Or can it be confinde to "some defenders" or "defenders with more latency in general"?

    Knockback with this plugin is sort of buggy. like you knock somebody off something 3 times with knockback enchantment and they keep teleporting back. very annoying for pvp servers. other than that this is a good plugin

    Bugs:

    1.Theirs something wrong with the bow glitching like it always lags you back AND the push back glitch (When you're running or walking and suddenly you "lag" and can't move. You like move forward then go back to the block you were on until you rightclick or shift.). This has something to do with NoCheatPlus. However, I dont have this problem at other servers. Check out my server: glowstonepvp.com and my config: http://pastebin.com/kieeTPpf

    2. Fences, if you right click them with a golden/god apple you can eat it while running.

    Please help me out with these problems! I'am willing to pay 10$ to the person who fixed these problems.

    Is it recommended we use latest jenkins on our 1.8 spigot protocol servers?

    @iarepande: Go

    So "ncp kicklist" or "ncp denylist" shows their names ?If so, did you do ncp unkick PLAYERNAME" ?

    What's your version of NCP? What does the serrver log show when they get kicked?

  • Avatar of iarepande iarepande Sep 15, 2014 at 01:14 UTC - 0 likes

    @MyPictures: Go

    I got two people who got kicked today and they are on the kicklist and I have done literally every command that could get them off but they can't login.
