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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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

Alright, i was just going there, because you stated "not saving what you put in", but i assume that was about the config display with using a paste (did you forget to set "language" to "YAML"?
So the situation is that even the command-aliases you put in won't work.
That's the moment when we really need the output of the "ncp version" command, can you just copy the text here? Maybe the feature can't work if NCP can not access something, are there any other errors in the logs during startup?

You can use the paste (http://dev.bukkit.org/paste/) and set language to YAML, then post the link, it'll show the spaces right. Or use the code tags that i have mentioned below (@asofold).
Looks like part of the check is active and the commands are specified in there.

The configuration of NCP has a section under the key "protection". I would like to see that, you could send it by private message (pm). To make it better viewable enclosing it in code tags would be good. If it's not so secret, you can also post it here.

Can you pm the part of the config (protection: ...), just with
<<code YAML>>...<</code>>(The ... should be the protection section in a new line, doesn't display as usual.)

Posted Nov 13, 2014Just 1 more thing. how come whenever I change like the messages in the config and I reload my sevrer the messages say for example: /pl i changed that to say like "You do not have permission for this command." Then i reload my server then i try /pl but the default message comes. I also tryed /ncp reload. Plz help. That goes for every command like /pl and /op...

@killerboss707
That's right. If you use permissions too, i suggest getting rid of OP, unless you need it for (stupid :p) command blocks.
If it is just that, you might also have a look at the vanilla settings (http://minecraft.gamepedia.com/Server.properties):
1 - Ops can bypass spawn protection.
That might help in addition, though some permission plugins might alter how OP relates to default permissions (at least WorldEdit, WorldGuard, PEX had had a setting for that ages ago). If OP is just for command blocks, you could set op-permission-level to 2 as a fall-back, provided you can get permission for ban etc. yourself.

Yes. In the config of NoCheatPlus, there is a entry named "opinconsoleonly"
If you set this to true (default is false), then only the console will be able to run the /op command.

Could you post the output of the "ncp version" command?

I don't understand fully how the things relate:
They use "gear" and THEN
Is "gear" really necessary to heal fast and mix drugs fast? What is "gear"?
Are therre special mods/plugins involved with "gear" and "mix drugs"?
