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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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 Jun 22, 2012Can't wait for a dev build lol. This version is to buggy to run on big servers so i'm currently using Anticheat. But that has many many bugs with checks this was always the best using it for more then a year. Wish there was just a simple NoCheat that just keeps up to date without all this "good new features"

No, definitely no. The plugins is still active, I continue to assure support during the Neat exams and an update is planned for the next week.
@asofold
You will be able to choose if you went to send data to the NCP database.

Those few weeks are just about over, the update is to be awaited very soon (next week) (see posts of Juliui one page further or two).
@Juliui I would be "almost concerned" if player names get sent somewhere via the web, but if you make it configurable not to be used if desired, then all is fine :)

Posted Jun 22, 2012Hi there,
A couple of our users have just come to me and said you're discontinuing support for this plugin in the next couple of weeks and I just wanted to confirm this before I went hunting for a viable alternative.
Thanks for your time Dave

During the time we have start a full rewrite of NoCheatPlus. But the Neat exams start and he had don't be able to update NCP. Neat finish his exams this afternoon, and the next update is for less than he week. The Jenkins isn't completely setup yet, but I'll provide you the link tomorrow. So yes, it's still active and supported. More than ever.

Since we don't really change the "idea" of NoCheat I think it's still spamming the checks message, like in Nocheat. But he can try to do some change in the config to avoid that...
@mcapplbee
Oh man, please be less patronizing. About the web interface, it's will be like a global database of cheaters (Mcban, cheater and hacker version). I think it's can be useful. By the way it will not slowdown the development because Neat do the Java, and I do the web interface. The poll says that the peole agree to an Essentials integration. It will not change anything for you, except that when you download essentials you will have NCP. If you don't want Essentials, you can just download NCP here.

Posted Jun 21, 2012Okay 1. It does NOT need a web interface. That would be a waste of time. 2. Do NOT integrate it into essentials.
Why can't things just be simple like they used to be.

Posted Jun 21, 2012Question:
I talked to an Admin on my server and they told me they were every once in a while getting the same out-of-range PvP error from some dude. Does this plugin spam the error if it is definitely happening like the original NoCheat, or do just what this admin told me?

Posted Jun 21, 2012Also we talk about NCP in general. We are very motivated to make NoCheatPlus THE anti-cheat plugins for bukkit, and we will do everything for that. Version 3.7 will improve performance, we will start right after it working again on new functionality especially the web interface. About the API, we've found an interesting possibilities wich allow us, without making NCP bigger, to make NoCheatPlus compatible with others "big" plugins without the need for the dev of the plugins to hook inside NoCheatPlus. We'll keep you in the loop.
@Hans6666
It is normal, since the 3.6 is very laggy. We fully rewrote the NCP engine in 3.7, and the update will be available next week.
@GameAnarchy
NoCheatPlus need to do a bunch of calculations, it's normal that it's drop down a bit your player limit. By the way, the 3.7 will be almost 2 times faster. Available next week.
