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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

This is an excellent plugin. Thank you.
Nice job man :D
One suggestion, you should integrate "NoPwnage" into this plugin as well. I think if you look at the comments there, he is not supporting it anymore.
Then you would have complete antispam protection :)
Hey Neat, There is an issue when players are swimming, that they get kicked for flying? I got told it happens most when they are swimming down.
Great extra's btw!, Squirzy
@NeatMonster
I like how you are so active. Cheers.
@carstorm
Give them the permission node for minimap mods, NoCheat+ does have this capability.
@carstorm Why people never read the Instructions.txt file?
Rather than block or allow all mods you should have each mod individual being able to be blocked. I want people to be able to use minimaps, but not flying and such.
@MarioG1
Please inform me how to disable kicks? I just want canceled commands kicking is buggy so far ;) So not yet :)
@juodas Can you be clearer please?
@ihasamoose Fixed in the latest version.
@UnitedFactions Simply remove cmd:kick from the actions list of the check, excepted if you're talking about the fly tracker's kick, then you'll need to disable the check itself (but the issue should be fixed now).
To everyone: I'll now focus on improving and making checks really stable, meaning that I won't add a lot of new checks like I did the previous days. Then I'll work on the new community aspects of NoCheat+ (white/gray/blacklists of accounts, IPs, etc.).
I found a bug in the latest version of no Cheat:
You get kicked if you swim up waterfalls.
Hello how do i Disable kicking in the config I tried everything.

Players are complaining that they keep getting kicked going up/down ladders very frequently for flying.
Thanks, Austin
@andrewkm
You should use NoPwnage by Evenprime to stop those bot attacks.
@juodas
You will need to provide more information here. Perhaps a server log of the error that crashed your server.
My players told me to use this plugin, but its crashing. Im using CB 1.2.5 R-1.1 It crashed when i was moving, so i deleted it. If you want you can test.
@NeatMonster
Looks like i missed you (was downstairs) - you left too fast :P Im here now.
@NeatMonster
Please come on IRC / Esper / #nocheat if you have a moment.
@tomori_peti Use xAuth.
@andrewkm Thank you for the detailed information. The issue is now fixed, just wait for the next version.
@MutinyCraft Thank you for the comment. Like the previous, it's now fixed and it'll be in the next update.
I wasn't online when this error occurred, but it spammed about 8-10 times on the console and I just noticed it so I thought I would post here. It looks like it has something to do with crafting snowman or possibly the snow created by snowman. Here is the error: http://pastie.org/3755598
On another note we should start idling on esper in the #nocheat channel guys! :) Update your scripts, I have an am currently only one there.
