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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

ProtocolLib

Allows NoCheatPlus to activate packet-level checks, covering a range of exploits that can't be monitored using ordinary means. Since roughly Minecraft 1.7.10, the fight.speed check can't work as expected anymore, due to changes in CraftBukkit. With ProtocolLib this can be repaired.

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 create an issue/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". (Latest versions of Spigot contain features of Orebfuscator.)

    MyPictures:

    I have this

    fastclick:
      active: false
      sparecreative: true
      tweaks1_5: true
      limit:
        shortterm: 4
        normal: 15
      actions: cancel vl>50 log:fastclick:3:5:cif cancel
    

    I thought that setting active to false would do the trick but people still reported problems. My config version is 670.

    @rhaegals: Go

    You could ...

    • Single plugins out (remove half and check if it is gone, then half of the remaining half etc.)
    • Provide a plugin list (pm or here) so we can start guessing...

    @PrimoHighDefinition: Go

    We are not in too much of a hurry, yet. Because we don't store long term data, changes are not as massive for NCP.

    The fastclick check.

    @rhaegals: Go

    Sorry I don't know what your issue was again, hard to keep up in comments. You could open up a new ticket and talk there.

    Which checks should I disable to allow Inventory Tweaks to work on my server?

  • Avatar of rhaegals rhaegals Apr 01, 2014 at 14:04 UTC - 0 likes

    Nothing helps... Yes, I have plenty of plugins. Would be easier if we chat via skype? Please add rhaegals-nest

    Thank you.

    @Shooty_: Go

    @MyPictures: Go

    A typo? The damage amount is calculated on the server-side, but clients can get more critical hits. Forcefield is reduced, though probably being able to reduce it further, it can't be fully orevented.

    @rhaegals: Go

    If ...motd.active is set to false, NCP should not send anything. Could be another plugin (otherwise a bug).

    @rhaegals: Go

    Did you also set allowall to true? I need to take a look at this and check if its broken or not. Whats your NoCheatPlus and CraftBukkit version? Have any other plugins that might disable mods over motds?

    Hello,
