NoCheatPlus
Detect and fight the exploitation of various flaws/bugs in Minecraft!
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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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.
Recommended
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 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.)

Posted Aug 20, 2012J'utilise DynPad pour le fun et les dégâts de chute mais il semblerait que NoCheatPlus gêne pour le trampoline en diamant, c'est pas très grave et ça arrive pas tout le temps mais quand même
Pour les lags j'utilise beaucoup de gros plugins (Orebfuscator, Factions, Dynmap, NoCheatPlus, etc...) donc ça vient peut être pas de NoCheatPlus
j'ai aussi un autre bug mais je sais pas d'où ça vient quand on meurt et qu'on fait /back on arrive dans le sol, sous là où on est mort

Posted Aug 20, 2012Dev build 34 does not fix the "Falling out of world" issue. It's spamming people falling out of the world who aren't even online!

Posted Aug 20, 2012@juloo65 OK, reposte un message si le problème est toujours là. Quand aux lags, je veux bien croire que cela puisse être de la faute de NoCheatPlus, mais par exemple je n'ai jamais rencontré un seul ralentissement sur mon serveur de test.

Posted Aug 19, 2012Just adding more info to the build 33 problem (which im guessing is because of proxy work)
People are often falling into the void too (like said below) and sometimes people are dieing of hunger EVEN AFTER logging out for almost 3 minutes. Really, really, weird haha.
Who knew trying to enable flymods via bukkit would be so difficult?!

Thank you for your reply.
Is it possible to see if the user has the client installed in general? Then I could just kick them on the login screen.
Due to the unique items in tekkit I cannot prevent kill aura, speed, or flight (They have items like this in the game already).
My best bet is to see if the cilent is installed, and then kick them. If this is possible which config change should I look at?

NoCheat+ has nothing against modded Craftbukkit versions and we will never force a owner to use original Craftbukkit with NCP. However we will not add code to support Tekkit or whatever mode you use. NC+ will only do check for vanilla Minecraft and nothing else. It would take too much time if we would add special tekkit support to NC+, we only focus on the vanilla checks of NC+ and try to make them as good as possible.
NC+ actually would work with Tekkit, it may have problems with all the new blocks that are in Tekkit. You should take a look in the config file and disable unneeded buggy checks for it.

Posted Aug 19, 2012I am using dev build 33 and having the issue of the server saying "playername fell out of the world" when players log out, the players are not actually falling at all and they are exactly where they where before they logged out. This happens in build 32 as well for me.
