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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

    @sparts: Go

    I can't judge this - i also can not reproduce it, i don't take damage jumping off 2 blocks high in 1.7.10. Maybe you are running a faulty build of server or NCP - what is the output of the "ncp version" command?

    @Schneidertm: Go

    Our dev builds support 1.7.10 and are available at the jenkins location, linked above. Currently we are going for release, and are mostly waiting for feedback on the latest dev build.

    Do you can recommend a dev version for 1.7.10?

    @VideoGameBlackBelt: Go

    It will by default configuration protect against pretty much every hack that is known to NoCheatPlus. There is the possibility to change stuff in the configuration if you feel its too strict/unstrict or has some check enabled which you don't want/need.

    Is the plugin by default guarding the server or do I have to configure the config top to bottom for best results?

    @sparts: Go

    You can set SF speed with checks.moving.survivalfly.speedingspeed (default is 200 and only for sprinting if you meant that) and we would need more information's about the server mod and plugins you are running on. I recommend created a new ticket for this half heart issue and just answer all the questions from the "Defect" layout please.

    @GreenGrizzlyBear: Go

    You defiantly need CompatNoCheatPlus on your server if you run citizens, otherwise the NPCs will throw out violations. If you still find compatibility issues even with CNCP installed then fell free to poke @asofold over at CompatNoCheatPlus DBO page.

    How does this plugin affect citizens?

    Skript is definitely the best plugin I've come across so far.

  • Avatar of sparts sparts Jul 28, 2014 at 02:15 UTC - 0 likes

    How would I go about allowing a higher speed and how much of a higher speed? I mainly use survivalfly to stop waterwalking and flying.

    I have tested jumping off of two blocks high in vanilla and I don't take damage. If I'm not exempt from survivalfly, I take a half heart of damage if I jump off of two blocks high. Its no biggie to me, but I had a couple players complain about it. I'll just let them know thats how it is.

    I appreciate all of your help. :)

    @asofold: Go

    I pulled it from github a few days ago. The spawn is about 4 blocks above the ground, then there are solid blocks underneath them. And yes, it's an exact login.

    @travja: Go

    • Output of the "ncp version" command? 1.7.10 needs a dev build...
    • What height is your spawn at?
    • What blocks are underneath/around your spawn (also how deep/solid)?
    • Do you have use-exact-login-location set in bukkit.yml?

    @sparts: Go

    1x2 tunnels allow faster sprinting with jumping (hitting the ceiling with the head continously). However NCP can't detect this (yet), so it will trigger violations there. No way to allow it onyl for this special case by config, you could only allow a higher speed in general.

    "Are 2 blcoks high" - if they jump and fall, they will have fallen more than 3 blocks, cheaters could also create hihger fall distance though... what's the output of the "ncp version" command?
