Bans

The Bans Subsystem

Negativity has its own ban subsystem, it is flexible and can be used in two ways:

• manually, with commands
• automatically, by banning a player when they have too many warns

On v1, This subsystem is only used by Spigot and Sponge plugins, the proxy plugins do not use it.

Configuration

The ban subsystem configuration is located in the main config file (config.yml or config.conf) or in bans.yml for v2, and is quite simple:

• active: the main 'switch' of the subsystem, if true ban-related commands of the plugins can be used and players may be banned automatically for cheating (if they fulfill configurable conditions). Defaults to false
• processor: the ID of the processor to use. Processors are used to execute and fetch bans. Defaults to file
• auto : enable the automatic ban feature. Defaults to false
• time.calculator: a JavaScript code snippet to compute the duration of a ban. It supports the following placeholders:
  • %reliability%: the reliability of the alert triggering the ban
  • %alert%: the number of alerts for the cheat of the alert
  • %all_alert%: all alerts for the detected cheat since you added Negativity on your server
• reliability_need: the minimum reliability of the alert needed to ban a player. Defaults to 95
• alert_need: the number of alerts for the same cheat required before trying banning the player. Defaults to 10
• def.time: the number of bans for a player before banning him definitely. Defaults to 2

Configuration for each cheat (reserved to v2)

You can override the global configuration for each cheat. To do it, go in the cheat config file such as xray.yml, then add:

ban:
  reliability_need: 95
  some: "else"

Actually, this is all possible keys which can be overrided :

• active: Disable ban for this cheat only
• time.calculator: Work exactly as described before.
• reliability_need: Defaults to 95
• alert_need: Defaults to 10
• def.time: Defaults to 2

Alt account (reserved to v2)

If a player have been banned, you can prevent alt/multiples accounts.

To add an action, you have to create new section on alt part of ban config.

The key have to be the number of account needed to show. For example, if you set 3, the third account to log in will run the action. You don't have to set all account number. If you set only 2, and player have 3 accounts, it will run the action of 2 (near lower account). If you set 1, it will be showed for all account.

Available actions :

• alert : send message to alt account
• alert_mod : send message to all mod (= ShowAlert permission)
• ban : Automatically ban alt account
• ban_all : Ban all alt (just logged and all other previous). Warn: this is not available with all bans processor.

You have to set the sent message by using message: "My message". For message, it's used for direct send (not translated, just colored). For ban, it's used as reason.

About ban, you can set if it's definitive with def: true, or set the time thanks to time: 1000 (here, ban 1 second).

You also can set conditions to run the action. To do it, use :

condition:
   warning: 1

Now, there is only a check of amount of warn.

Finally, this is an example :

4:
    action: ban
    message: "Alt unauthorized"
    # the time of the ban in milliseconds.
    # set '-1' or "def: true" for definitive ban
    time: 360000
    # condition to be banned
    # Get Warn and Violation from ALL account
    condition:
      # Need at least 30 warn
      warning: 30

Ban Inventory (reserved to v2)

In /negativity <player> menu, there is an anvil which enable mod to ban (need permission to do /nban).

This inventory is a shortcut to nban command, which default configuration.

For example, if you want to ban player for Insult 2h, you just have to configure an item in this inventory and not have to write the full command.

To configure it, there is a "sanctions" section.

Example:

# The key is not specially used
cheat:
  # the name is used as item's name and also as the reason
  name: "&4Cheat"
  # the material of item in inventory
  material: RED_BANNER
  # the slot in the inventory
  slot: 1
  # Message sent to player who ban other
  message: "&6%name% &ahave been banned for %reason%"
  # The command which have to be done (Command used by console, so it have to be enabled for it)
  command: "nban %name% 30d Cheat."
  # (optional) the permission to see and use this item.
  # If is empty, it will be available for everyone which can access to this inventory
  permission: "negativity.sanction.cheat"

If you want to see different item according to permission, you can set multiple item at the same slot. There will be only the last item which is permitted for the player.

Processors

Like each processor have own working system, some of them don't have some features.

The "BanAll" indicator, show you if the processor is compatible with alt ban system.

Processor name	ID	Platform	Ban all	Comment
Proxy	proxy	All not proxy	Depend	More details
File	file	All	Not yet	More details
Database	database	All	Yes	More details
Command	command	All	Unknow	More details
AdvancedBan	advancedban	All*	No	Uses AdvancedBan
LiteBans	litebans	All*	Yes	Uses LiteBans
Bukkit	bukkit	Spigot	No	Uses Bukkit's ban system (which by extension is vanilla's one).
Sponge	sponge	Sponge	No	Uses Sponge's BanService (which delegates to the vanilla system by default).
MaxBans	maxbans	Spigot	Yes	Uses MaxBans
ProfessionalBans	professionalbans	Spigot & Bungeecord	Yes	Reserved to v2. Uses ProfessionalBans
UltraPunishments	ultrapunishments	Spigot	Yes	Reserved to v2. Uses UltraPunishments
DkBans	dkbans	Spigot & Bungeecord	Yes	Removed after 2.5. Uses DkBans

*All platforms where the plugin is, but Negativity doesn't ask for specific one.

Proxy

The proxy ban processor is simple: it send all ban request from backend server (Spigot/Sponge/Minestom/etc) to the proxy. Then, it's the proxy that manage it.

The ban is applied according to the proxy config, it means you need to config the proxy. The processor should be what you want to use (a plugin like Litebans, Negativity's solution like file/command/database etc)

File

Stores bans on the local filesystem. Useful if you only have one server.

Its configuration is located in the main config file, under ban.file:

• log_bans: whether old bans (expired or manually revoked) should be kept. Defaults to true.

Database

Stores bans in a database. Requires a valid database configuration.

Its configuration is located in the main config file, under ban.database:

• log_bans: whether old bans (expired or manually revoked) should be kept. Defaults to true.

Command

Executes bans via custom commands. Since this one only uses commands it does not support logged bans.

Its configuration is in the main config file, under ban.command:

• ban is the list of command to execute when executing bans
• unban is the same than ban, but for revoking bans

Both lists must contain strings, the order of the commands is respected.

Each command can contain the following placeholders:

• %uuid%: the UUID of the player
• %name%: the name of the player
• %ip%: the IP address of the player
• %reason%: the reason of the ban
• %alert%: the number of alerts for the detected cheat that triggered the ban
• %all_alert%: all alerts for the detected cheat since you added Negativity on your server
• %life%: the health of the player at the moment the command is executed
• %level%: the level of the player
• %gm%: the gamemode of the player
• %walk_speed%: the speed at which the player should walk

I want my own processor !

You can use command processor if you don't have lot of time.

To make your own, follow those steps :

1. Create your own ban processor.

It should implement com.elikill58.negativity.universal.ban.processor.BanProcessor's java interface.

2. Register this processor into Negativity :

BanProcessor myProcess = ...;
BanManager.registerProcessor("myprocessor", myProcess);

3. In config, change processor: "file" pour processor: "myprocessor".

("myprocessor" is what you wrote as plugin ID in registerProcessor)
