NoCheatPlus

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

Minecraft 1.11.2 and latest features are currently only available on Jenkins - once things stabilize, stable builds will be available here again.

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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

Make plugins like mcMMO 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. Phasing out: Citizens 2 should work with NCP out of the box, MagicSpells are working on compatibility too - rest will be integrated into NCP.

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.)

Thank you for this plugin! A person with a cracked client just joined my server and tried to break blocks to fast. The plugin reported this in my console and I joined the game and told him to stop or I would ban him and he said, "FUCK NO" and left. Then I IP banned him, lol. Thank you for this amazing plugin that helps protect servers!

Can u make a "cave finder" preventer, sins you can use and will bypass the orebfuscator: U have for instants the cave finder in Nodus, if u could use the same methode for finding caves perhaps u could make it so that the client thinks that it is only stone there and there for not see it.

You should explain more precisely what the problem is...

I don't know how this is fixable but with mcmmo when someone with I think a high level of excavation is breaking blocks quick it is being caught by nocheat+ and I get a steady stream of messages.

Neatmonster this is an issue with mcbans and I would assume any ban plugin that sends away their bans. If you added something to cancel the chat then we wouldn't need to add a mute to block the last 4 messages

Edit: this is in reply to your other comment

I had a problem with lag with nocheat too, but from doing some experimenting with the config, i figured out what it was caused from.

logging: active: false showactivechecks: false debugmessages: false prefix: '&4NCP&f: ' filename: nocheatplus.log file: false console: false ingamechat: false

As you can see, i shut off a few things, such a as logging, console messages, etc.. Give it a try, as it may work, but all servers are different, so it's hard to say if it will take effect!

When using the xray mod, even with fly disabled, there seems to be a small glitch. Walking on blocks into water is just fine, but if you try to walk from soul sand into water, it stops you. It's really no big deal, but it's a bit annoying.

Hey everyone! Today I'll only reply to questions that haven't obtained a sufficient answer. Thank you for your understanding.

@deleted_7536780 Are you sure you're using the latest version of NoCheat+? If you've a basic knowledge of Java, you should take a look at this page.

@deleted_8156133 Hum... Can you give more details about the "commands that don't take effect immediately" (is it an issue with NoCheat+ or MCBans also)? The IP-related stuff will be added with the web interface.

@xeNiums As you can see here, this permission allows the player to receive an "unlock code" when logging in. Also, it's not possible to block all XRays, so you should give Orebfuscator a try.

@darkknightcz Thanks for the report, I'll try to fix this bug for the next release.

@WhiteNightFury Instructions.txt*

@Tobseb You should see if there isn't any issue with your permissions.

@nicka1011 Are you using the latest version of NoCheat+? (Because the Unpushable check has been removed.)

@aviator1014 Instructions.txt*

@Jokaru Instructions.txt*

@np98765 Instructions.txt*

@Lyndon321 Hum... Are they kicked by NoCheat+? If the answer is yes, which check is kicking them?

@UnitedFactions Instructions.txt*

@StuckingFoned Instructions.txt*

@UnitedFactions The code hasn't changed but the clients have been improved to pass all NoCheat+'s checks.

* Have you read the instructions?

I haven't experienced that. Maybe you should find out the cause of lag first using NoLagg Examine.
