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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

You could replace the command from kick to cancel so they don't get kicked and the items don't dupe but when they drop, it cancels it.
That's what I did. ^_^

I would highly doubt that NoCheatPlus would cause lag on a player join. Although, it is possible depending on what you have running along side it or how its set up. Could also be the server itself.

Posted May 23, 2012Can you make NoPwnage track commands? For example some people /kill spam on my server, and /me spam would be a problem too... You could make it have a different config with the commands if you want, but just make it the same as the chat. Thanks :)

Posted May 23, 2012I get huge lag on player join. It happens only on "default" player, not on admins. Is it possible that NoCheatPlus causing it? It began when I moved form NoCheat to NoCheatPlus.

Posted May 22, 2012Hey I was curious if there was a way to allow people touse smartmoving mod while not allowing them to cheat any other way. If not I think it would be a great addition to the plugin. A feature that allowed you to enable or disable the use of some mods. And/or a permission node that allows a person to use a certain mod. Smart moving would be fun on a server if nocheat didn't make it render useless. But goodjob nocheatplus is awesome :).

Posted May 21, 2012Hey NeatMonster,
I just discovered that players without permissions can't use /nocheatplus (Shows unknown command)... I think this is a great false sense of security for people :D
Also, just wanted to compliment you on the stunning new BukkitDev page :D G'job!
