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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

    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.

    @MineCraftMyph: Go

    What are chat cooldowns? NC+ has a delay string and command which will delay the execution of a command.
    Or did you mean command spam? Like stop players from spamming too much commands in a short time?

    @Manic_Kaval: Go

    Several options:
    - Make sure they have no notification permission for NC+
    - Disable logging completely
    - Or disable the checks you don't want to use (will allow them to cheat those of course)

    Members on my server are receiving messages from NCP concerning other members when they fail a movement or blockbreak. http://i.imgur.com/6YVa0u1.png How can I disable this?

    What part of the NCP configuration handles command cooldowns? Is the command cooldowns separate to the chat? If not how to I make the cooldowns separate?

    @Shinxs: Go

    Yes. There is an API which allows you to exempt checks on specific players: https://github.com/asofold/NCPDocs/blob/master/wiki/development/api.creole (Id recommend checking out CNCP for some nice examples). However you cant disable the entire plugin with that API (would not make sense at all anyways).

    Is there some sort of API so that I can disable it for my plugin? Or just a way to disable and enable it for a specific player?

    @Chris_GSPvP: Go

    Build 742 should be safe to use - release might be anytime, though things are slighltly at "watching things evolve", concerning current events around the Bukkit project and the CraftBukkit server (code).

    Can anyone tell me if build #742 is safe to use?

    As secondly, when is the build releasing on bukkit?

    @Max633: Go

    That can't be generalized. The task has run one time and covered half a second. That is too much of course, but such can happen, e.g. on or file-io or a thread-switch, though the latter means that another thread took a long time.

    You could reduce / deactivate file logging (at least for console) in NCP.

    @chrisbruijnes: Go

    I will push a development build with a fix.

    Well, I never had this error I think untill I uploaded a spigot version while ago.
