Do cheaters on your server ruin the gameplay for players that are playing legit, and therefore legit players are going away from your server? You don't have enough time to monitor all the players on your server nor the will to do it? Well, congratulations, you just found a great plugin to put all your worries away!

FairPlayMinecraft is a client-side anticheat system which eliminates cheaters on a Minecraft server with ease. Players are being checked client side, which means the checks are not done on the server which results zero lag to the server.

The server is always running the latest plugin version.
IP: 89.34.96.15:25589 (running on version 1.10.2 with online mode set to true)
Server provided by:

fast and lightweight - players are being checked client side, which means the checks are not done on the server which results zero lag to the server
you can choose which versions (clients) and mods your players will be able to join with
your players can be asked to go through the check on every join OR they can be asked to go through the check only if you run /fpmc check <nick> command on them
active development - this project is being actively developed. I am open for new feature requests and of course for bug reports
You can see using which clients players joined with using command /fpmc p <nick> <page number>(http://i.imgur.com/NBlJ1ax.png)

Here is a video preview for the system in an early beta version I made a while ago (I am planning to make a new, updated one) so you can see how it works:

The system consists of three parts:

1. Spigot/CraftBukkit plugin
This part checks if player has ran the application which is used to scan if player has hacked client installed. Before running the application, player has restricted access to the server (eg. he is not allowed to move, to execute commands... - all that can be configured). When player runs the application which scans its Minecraft installation, the data is sent to the main server and then to the Spigot plugin. So the plugin receives the results and let the player play if it doesn't have any cheats installed, or run a command from configuration file if player has a cheat.

2. The application
The application scans player's Minecraft to see if he/she is running a cheat/hacked client. After that, it sends the results to the server which then does the rest.

3. Main server
The main server is used for the updating system and as a communication between the application and the plugin. It also sends the cheats filter to the application which allows it to determine if player is playing with cheats.

Some of you may think that this is a funny and unusual way of eliminating cheaters but, trust me, it is a good and precise way. I have been running a server with an average of 150 online players with this system. Although many of my players were young, they didn't have difficulties understanding what they have to do in order to play on the server. I must say that my players were very happy about that system because they could (finally) play normally, without cheaters. Also, my staff team had less to do - they did not have to monitor all the players one by one.

1. Download the plugin. It will be in a .zip format. After you upack it, you will see two files - FPMC_plugin.jar and FPMC.exe.
2. Put FPMC_plugin.jar in your "plugins" folder and restart your server. A config file and a welcome.txt will be generated at the following location: plugins/FairPlayMinecraft/.
3. Modify the configuration and welcome file as you wish and restart the server. Welcome file defines the message that will be sent to player that joins the server asking him to run the application.
4. FPMC.exe is the application which has to be ran in order to play on the server. You can upload it somewhere and provide a link to your players or you can just give them this link:

I totally recommend Nitrous Networks, not just because they are sponsoring this project but because I used their services when I had a server running and I can really say they are the best of all that I tried (tried like 5-6 hosting companies). Fast answering and polite support team, excellent performance and great network!
Go with this guys, you won't go wrong

Q: Will FPMC.exe make harm to my computer? My antivirus software detects it as malicious!
A: FPMC.exe will not make harm to your computer in any way. If your antivirus software flags it as a crap, please contact me so I can report the false-positive to the antivirus software company.
Here is VirusTotal report for the application - https://www.virustotal.com/hr/file/...56fea78eb840315d9dd1781c/analysis/1478883512/

Q: I have multiple BungeeCord instances and the plugin does not work properly for me, did I do something wrong?
A: You did not configure the plugin correctly. If you have multiple BungeeCord instances running, you have to list all the instance's IPs in plugin's configuration file under "multiple_ips" in format IP: PORT (without the space between : and P, I have added that space because if I didn't, a smiley would have appeared)

Many servers are practicing asking players which they suspect are using a cheat to give them a screen share (via Skype, Screenleap or something else). In other words, they are asking players to show them the screen of their computer so they can see if they are really using a cheat. The problem in that is that admins then have to wait for the players to give them a screen share and they can hardly check more then one player at the time.

If you set "check_command_enabled" to true in the configuration file, players will not have to go through the check (run the application) on every join, but only when an admin asks them to do so. For example, an admin suspects that player "abcd" is using cheats. He will then execute command /fpmc check abcd so the player abcd would have to go through the check - he will be asked to run the application and he will have restricted access (he won't be able to move, to execute commands and so on) until he does.

The "restrictions" section is easy to understand. If you want to disable movement for players who did not run the application yet, you will have to set "movement" to true. If you, for example, want to forbid executing commands you will set "commands" to true.

Benefits of using BungeeCord support:

players won't have to go through the check when they are switching between servers
players won't be able to execute BungeeCord commands when being asked to go through the check (for example they won't be able to avoid the check by going to another server with command /server)

This is how you can enable BungeeCord support:

Put the plugin in "plugins" folder in your BungeeCord server
Start the BungeeCord server, then stop it.
A configuration file config.yml will be generated in /plugins/FairPlayMinecraft. There you can change the port the plugin and BuneeCord will be using to communicate. Default is 11414. You don't have to change this. Change it only if there's something else running on that port. Don't set that the same as your server's port!
Start the BungeeCord server.
Put the "FPMC_plugin.jar" in "plugins" folder in your Spigot server and start it.
A config.yml in /plugins/FairPlayMinecraft will be generated. Under "bungeecord_support", set "enabled" to true, set "address" to the address your BungeeCord instance is listening to (in format IPORT, for example 172.16.254.1:25565), set "ip" to the IP address of the BungeeCord and set "port" to the port you set in the config.yml of the BungeeCord.
Start the server!

Example part of the config.yml for BungeeCord support on Spigot server:

Code:

bungeecord_support:
    enabled: true
    address: '172.16.254.1:25565'
    ip: '172.16.254.1'
    port: 11414

(if for example the BungeeCord instance is running on 172.16.254.1:25565)

fpmc.bypass.all - player with this permission cannot be checked on join or when somebody executes /fpmc check command on him
fpmc.bypass.join - player with this permission cannot be checked on join
fpmc.bypass.command - player with this permission cannot be checked when somebody executes /fpmc check command on him
fpmc.check - player with this permission is able to use command /fpmc check <nick>
fpmc.notify - players (admins) with this permission will be notified in game with a message if a player tries to join the server using a cheat (if enabled in config!)

Note: Players who are OP automatically have the fpmc.bypass permission and therefore they don't need to run the application.

As of version 5.0.0 you can create your own filter - choose with which versions (clients) your player will be able to join. To do that, go to http://fairplayminecraft.com/filter/versions.php and follow the instructions there. You can add the default filter there which allows players to join using all vanilla and all Optifine versions and along with it you can add your own versions (clients) by clicking the "Add versions (cliens)" button. After you have created your list, click "Download filter" and put the file version_filter you will download in /plugins/FairPlayMinecraft/. Then set "use_custom_versions_filter" in config to true and restart your server!

The plugin does not just simply allow players to join with Forge, but it checks the mods player has installed because there are cheats you can install using mods in Forge. That's why you can of course make your own list of mods which will be allowed on your server here: http://fairplayminecraft.com/filter/forge.php
Just drag the .jar of the mod in the area and do that for all your mods. Then click "Download filter" and put the file forge_filter you will download in /plugins/FairPlayMinecraft/. After that just set "use_filter_for_forge" to true and restart your server!

LiteLoader support
It's the same as for the Forge support. You have to make a filter here: http://fairplayminecraft.com/filter/liteloader.php and put it in your plugins/FairPlayMinecraft/ folder and then set use_filter_for_liteloader to true in config.yml.

FPMCAPI.sendCheckRequest(player, boolean) - sends the check request to the specific player

player = player you want to check
boolean = true if you want to send the player the message from welcome.txt or false if you don't want to send him a message

HasCheatEvent event - is triggered every time when a player goes through the check (runs the application)

event.getPlayer() - returns the player who went through the check
event.hasCheat() - returns 1 if player joined using cheats or 0 if the player does not have a cheat

Bungee.checkPlayer(String) - sends the check request to the specific player without having to know on which server the player is.

String = player's nickname

FairPlayMinecraft works on the principle of whitelisting. All legit (original) versions of Minecraft and all Optifine versions are whitelisted and only with them you can join the server. Forge is currently not supported.

The plugin should work on any Spigot version. It has been tested on the latest 1.7, 1.8 and 1.9 builds. The application currently works on Windows and Linux OS. Mac OS version is planned.

If you need help, found a bug, found a cheat that this system doesn't block or something is not working for you, please use the "Discussion" to contact me. You can also send me private message.
If something is not working well for you, please don't go straight forward to the reviews section and give the plugin a bad rating. Please report the problem first so I can fix it.
Thank you!
