# BattlEye

## Introduction

BattlEye website
Abbreviation: BE

BattlEye is an anti-cheat tool created by BattlEye Innovations. It is currently included in Bohemia Interactive's Arma, Arma 2 and Arma 3 series as an optional installation and server configuration option.

It works by scanning connected clients for various cheat an exploit methods and upon detection, disconnecting (kicking) the offending clients. You can find more details about the BE cheat scanning engine on the info page.

## Privacy

BattlEye will never violate your privacy in any way. The EULA clearly states this when installing BattlEye. Any other statements found anywhere else are superseded by the EULA.

BattlEye always has and will secure the user's privacy and protect against any sort of software exploitation from outside.

## Setup

You can find out what the latest version is by visiting the news section.

### Installation

Installation of the BattlEye client is an option during the initial game installation process.

BE updates itself automatically during a running MP session with internet access. However in the case of troubles use the following options:

a)

Arma, Arma 2, Operation Arrowhead, Arma 3,
2. Now you need to put BEClient.dll to the right location:
Windows 7
Windows XP
C:\Documents and Settings\%USERNAME%\Local Settings\Application Data\ARMA 2 OA\BattlEye\
STEAM
C:\Program Files (x86)\Steam\SteamApps\common\ARMA 2 Operation Arrowhead\Expansion\BattlEye\
 ! NOTE: You need to use the right subfolder for your game version (Arma/Arma 2/Arma 2 OA/Arma 3…).

b)

#### Automated BEClient.dll installer

2. Next run it and use run as Administrator (select file by left mouse click, right mouse click, select the run as option).
It is a very fast silent-installer. This means normally you will not notice anything - no application widow, no progress bar, no completion info. Only if there are issues, it will speak up.

The automated installer looks for the BEClient.dll on your computer:

1. If your BEClient.dll is same or newer, then installer does nothing,
3. If the BEClient.dll is not found, it will install the latest BEClient.dll.

You can verify if it was installed by checking the software uninstall list. You find it under "BattlEye for OA uninstall".

#### Installation on Linux servers

First of all, set up a working Arma 2 or Arma 2:OA server. When your Linux Arma 2 server works as it should, you can follow these instructions to install and enable BattlEye.

1. Log on to your Linux server with SSH or open a new terminal emulator window.
2. Change directory to where you have the Arma 2 server files installed. In this example we'll use "/home/arma2/arma2server" as the server's installation directory:
cd /home/arma2/arma2server
3. Next, create a directory for the BattlEye server.
• For an Arma 2 server, the path should be:
./battleye
• Whilst for an Arma 2: Operation Arrowhead server it's:
./expansion/battleye:
• i.e. mkdir battleye or mkdir expansion/battleye
4. Download the correct BE server from the BattlEye website - there's one file for Arma 2 and another for Arma 2:OA. You can use a command-line download tool such as "wget" or "curl" as well:
• For Arma 2, use:
• Whilst for Arma 2:OA it's:
5. You now have the BE server component installed. Enable it in your game server's config with "BattlEye=1;".
6. Start the server again and watch the log file (usually "log.2302.txt"). With BattlEye enabled, you'll see an extra line of output when the server is started. For example:
14:20:22 BattlEye Server: Initialized (v1.122)
7. (Optional) In order to administrate your BE server remotely, you'll need to create a configuration file for the BE server. It should be named "beserver.cfg" and placed in the BE directory you just created.
• For an Arma 2 server, run:
• For an Arma 2:OA server, do this:
• For more details, see the section below on RCon.

### Configuration

#### Client

Apart from installation there is no additional configuration required for game clients.

#### Server

Refer to the server.cfg section on how to enable BattlEye on a game server.

 ! NOTE: If you run multiple game servers on one machine, you need to specify separate BE paths for each in the server startup parameters.

## BE commands

 ! NOTE: The #beserver command has been disabled for now, due to the game admin hijacking hack. You need to use the BE RCon tool to ban players from your server.
 ! NOTE: The commands are case insensitive. In other words you can write them all lower case.

### GUID banning

BE can permanently or temporarily ban players from your server. The advantage over Arma 2's PID banning is that the BE GUID cannot be hacked/changed client-side, therefore the only way for a player to get unbanned is to buy a new game/cd-key.

The following commands are available to manage GUID bans:

Command Description
bans Show a list of all BE server bans.
ban [player #] [time in minutes] [reason] Ban a player's BE GUID from the server. If time is not specified or 0, the ban will be permanent; if reason is not specified the player will be kicked with "Banned".
addBan [GUID] [time in minutes] [reason] Same as "ban", but allows to ban a player that is not currently on the server.
removeBan [ban #] Remove ban (get the ban # from the bans command).
writeBans removes expired bans from bans file

You can either enter them via BE RCon or in-game using "#beserver [command]" (if logged in as admin). For example:

#beserver ban 11

Keep in mind that the "player #" used here, is the one listed by BE's "players" command.

BattlEye GUID and IP bans will now both be loaded from and saved to "bans.txt" (no longer "guidbans.txt" and "ipbans.txt") in your server's BE working directory.

## RCon

b0.92.

Since BattlEye server version 1.102 you can control your Arma game server remotely (without having to be in-game) using the BattlEye RCon tool.

2. Create a file called "beserver.cfg" in BattlEye working directory on the server.
4. Start the RCon tool on your computer.
5. Connect to your server with its IP, port and RCon password.

### BattlEye working directory

The BattlEye working directory is a folder in one of three places:

1. A folder named "BattlEye" within the Arma 2 application data folder.
2. A folder named "BattlEye" in the path given by the "-profiles" startup parameter.
3. In a folder given by the "-bepath" startup parameter.
 ! NOTE: Even with custom locations you will still need the BattlEye .dll's or .so's ALSO in the default location ("\BattlEye" for Arma 2 or "\Expansion\BattlEye" for Arma 2:OA/CO) for BattlEye to start.

#### The Arma 2 application data folder

In Windows Vista, 7 and 2008, that's the path given by "%LOCALAPPDATA%\ArmA 2" for Arma 2 and "%LOCALAPPDATA%\ArmA 2 OA" for the Arrowhead dedi. A typical value is:

In Windows XP and 2003, the application data folder is "%USERPROFILE%\Local Settings\Application Data\ArmA 2". A typical example is:

C:\Documents and Settings\username\Local Settings\Application data\ArmA 2

These locations are the default and are used, if you launch the dedicated server without using either the "-profiles" or "-bepath" launch parameters.

#### The -profiles location

The path given as the "-profiles=..." startup parameter used when launching the Arma 2 dedi. If, for example, you would launch the Arma 2:OA dedicated server using:

arma2oaserver.exe -profiles=D:\Games\ArmA2

then the BattlEye working directory would be:

D:\Games\ArmA2\BattlEye
 ! NOTE: Even if using custom locations you will still need the .dll's or .so's ALSO in the default location ("\BattlEye" for Arma 2 or "\Expansion\BattlEye" for Arma 2:OA/CO) for BattlEye to start.

#### The -bepath location

You can also specify the BattlEye working directory directly using the startup parameter "-bepath". Example:

arma2oaserver.exe -bepath=D:\MyBattlEye

In this case, the BattlEye working directory will be:

D:\MyBattlEye

If path contains spaces, encase everything in quotes:

arma2oaserver.exe "-bepath=D:\My BattlEye"
 ! NOTE: Even if using custom locations you will still need the .dll's or .so's ALSO in the default location ("\BattlEye" for Arma 2 or "\Expansion\BattlEye" for Arma 2:OA/CO) for BattlEye to start.

#### Full examples

Here are examples of the full paths to the "beserver.cfg" file for a few different cases.

• The examples assume that the username of the user that will run the servers is "jimbob".
• "Arma 2" means running the "arma2server.exe" whereas "Arma 2:OA" means you're launching "arma2oaserver.exe".
Arma 2, Windows 7/Vista/2008, default: C:\Users\jimbob\AppData\Local\ArmA 2\BattlEye\beserver.cfg
Arma 2:OA, Windows 7/Vista/2008, default: C:\Users\jimbob\AppData\Local\ArmA 2 OA\BattlEye\beserver.cfg
Arma 2, Windows XP, default: C:\Documents and Settings\jimbob\Local Settings\Application data\ArmA 2\BattlEye\beserver.cfg
Arma 2:OA, Windows XP, default: C:\Documents and Settings\jimbob\Local Settings\Application data\ArmA 2 OA\BattlEye\beserver.cfg
Any Arma 2, any Windows, -profiles=D:\profiles: D:\profiles\BattlEye\beserver.cfg

#### Linux

For Linux dedicated servers, the default locations are:

• For the Arma 2 dedi, it's "./battleye"
• For the Arma 2:OA dedi, it's "./expansion/battleye"

### Sample beserver.cfg

RConPassword xyzxyz
MaxPing 200

### RCon commands

 ! NOTE: The commands are case insensitive. In other words you can write them all lower case.
Command Description
loadScripts loads the "scripts.txt" file without the need to restart the server.
missions Returns a list of the available missions on the server.
players Displays a list of the players on the server including BE GUIDs and pings.
kick [player#] Kicks a player. His # can be found in the player list using the "players" command.
MaxPing [ping] Changes the MaxPing value. If a player has a higher ping, he will be kicked from the server.
logout Logout from current server, but do not exit the program.
Exit Closes the connection.
Say [player#] Say something to player #. -1 equals all players on server (e.g. "Say -1 Hello World!")
Server commands are passed directly to server
#mission [missionName] - Loads the given mission on the server.
 ! NOTE: Look at the GUID banning section for additional commands.
