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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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 Oct 5, 2013@asofold Thanx man i dont mind those hacks what i don't like is speed hacks and fast break hacks and xray but reis mini map and other mods i don't mind as long as they don't destroy stuff. Hell i use a few mods why would i care if my players do .. Gotta love reis mini map .. :-) Wish there was a plugin made like reis mini map that would give a mini map to all my players . Don't think its possible though . :(
Btw @asofold I just swapped to this from anticheat and i must say yalls support is better by far . There plugin is worse in many ways in my opinion i love the nocheatplus plugin there plugin made 3 blank lines on chat on every player that logged in and in my opinion that makes the chat look ugly and i had many more problems to with anticheat none at all with this other then the little 1 blank line thing but it was no where near as bad as 3 blank lines . Really no big deal though.

Remove the entry configversion.created once and do "ncp reload".

Posted Oct 5, 2013I updated the config for the recent build and I still get the message that the config is outdated. I'd rather not regenerate it as I have a lot of changes.

Yes, disabling it will allow some client mods to use features and disallow some others client mods features. But those client mods are the "polite" ones, there are others that don't care about any "motd" or plugin messages anyway. So leaving it activated will just help some kids not to use their xray or flying cheats.
So you need some measure against xray anyway, and NCP should catch a lot of what people might try with their cheat clients, so totally disabling should not mean too much harm, though it may confuse people that think they are allowed to use flying or whatever features of their client.

@asofold
Be aware that disabling this will allow some cheating on your server (means your players may activate some cheats of mods such as zombe, etc....)

Maybe the block codes have been changed on Zombes side. Note that the "disabling" of client features is a completely mutual thing for the client, altered clients could try any cheats anyway. I assume most are caught or reduced by NCP at present, though.

Posted Oct 2, 2013Why is it no longer blocking Zombes? People can cheat.

I suggest to check if you turned off file logging or all logging for the moving section, at least for the lower violation levels.
The moving checks are on the heavy side and we will try to make them more light, but at present we regard them as somewhat acceptable, given the paradigm that we cover as much as reasonable, which means a lot of checking. Disregarding logging the moving checks are designed to run smooth and should not produce big spikes, except for the case of contributing to an already bigger lag spike caused by something else, leading to many events queued for processing.
You can open a ticket and name some plugins you use (and maybe configurations), so we might have a look at what to optimize. Please don't forget to add versions and server specs in such case.
There might also be some ways to configure NCP slightly differently, in case you don't need the most strict checking (subject to discussion in a ticket rather).

Posted Oct 2, 2013Can you guys code a little lighter on the PlayerMoveEvent? I'm trying to reduce player motion lag on my server and I see that this plugin uses the most resources on the PlayerMoveEvent.

Seems to be alright for me: http://puu.sh/4E2mh.png . Do you use any plugins that modify block breaking to be faster? Normal pick with no enchantments? Version of CraftBukkit and NoCheatPlus? The docs tell you how to configure FastBreak: https://github.com/asofold/NCPDocs/blob/master/wiki/configuration/checks/blockbreak/blockbreak.creole
@xXrobin99Xx
Please open up a new ticket or ask directly here. We only use PMs for critical stuff or if you don't want to share some server informations with the public.

Okay please make a ticket (Defect layout) for us, so we get all required informations. Also be sure to post your entire NC+ configuration file.
@asofold
As far as I know it is. Haven't seen anything else then packet spamming. The strange thing is that MorePackets should have catched this one also (because he was running while having it on). Hmmmm, maybe he uses something else?

Healing is still done by timing on server side?
In that case the cheat could just heal at the maximally possible speed without ever triggering a violation (thus work), i assume the alerts do prevent healing faster than what NCP assumes to be maximally possible. A regular player would have to keep moving etc. in order to get the same effect.

No, i don't have fastheal permission for anyone. Theres this new mod that allows them to constantly heal. The nocheatplus notifys they are fast healing, but it doesn't block it. Heres a link to the video: http://www.youtube.com/watch?v=7__oy6B2r6k

It already does. The check is called FastHeal. Do you have problems with it? Permissions setup is right? Version of Server and NoCheatPlus?
