Introduction

Apart from being informative, this page will also take you through a step by step process to install, configure and run your server The majority of directories and paths are customiseable, however those defined are all consistent with the tutorial instructions.
The majority of content has been extracted from this Tutorial thread, or threads linked from it

Installation

Requirements

  1. Steam Account
  2. Ownership of Arma 3
  3. Supported Operating System
    • Windows: 2008 or later
    • Linux: (TBA)
  4. Minimum Hardware:
    • CPU:
    • RAM:
    • Disk

Instructions (Windows o/s)

The following instructions will guide you though setting up one Arma 3 server on 1 box, however they will also set the foundations for installing multiple servers on that same box

  1. Login to the server as Administrator
  2. Install the latest version of DirectX
  3. Create the following empty directories
    • D:\Apps\Steam
    • D:\Games\ArmA3\A3Master
    • D:\Games\ArmA3\A3Files
  4. Download steamcmd.exe and save it to your targetted Steam install directory (E.g D:\Apps\Steam)
  5. Run the steamcmd.exe. (This will download and install the required steam files to your custom steam directory)
  6. Create an ArmA3_Steam_updater.cmd file, (Example shown below) and save it to D:\Games\ArmA3\A3Files
  7. Run the ArmA3_Steam_updater.cmd file
  8. Just after logging into Steam, the console window will hang and ask for a validation key
    • Steam will have automatically sent you an email with this validation code, which you then need to input at the command prompt
    • The Update console window should then continue to run and install ArmA3 ((DEV or STABLE) version to the target directory as defined in the .cmd file) eg (D:\Games\ArmA3\A3Master)
  9. Create a shortcut for the ArmA3Server.exe on the server desktop
  10. Add the following parameters to the Target Line in the shortcut tab of the newly created desktop shortcut
    • -port=2302 (Required if running multiple server instances including any previous ArmA2 instances)
    • "-profiles=d:\Games\Arma3\A3Master"
    • -config=CONFIG_Vanilla.cfg
    • -world=empty
      • so it looks something similar to the following
      • "D:\Games\Arma3\A3Master\arma3server.exe" "-profiles=d:\Games\Arma3\A3Master" -port=2302 -config=CONFIG_Vanilla.cfg -world=empty
  11. Add firewall rules for the UDP ports
  12. Create a simple Notepad document called "CONFIG_vanilla.cfg" and save it to the root folder of your ArmA3 install on the server D:\Games\ArmA3\A3Master (See below for ".cfg" content)
  13. Start up your shortcut, check the server runs. (You will see a console pop up in your desktop after a few seconds)
  14. Close the console window down, then you will need to edit the following files which will have been automatically created
    • D:\Games\Arma3\A3Master\Users\Adminstrator\Administrator.Arma3Profile
    • D:\Games\Arma3\A3Master\Users\Administrator\Arma3.cfg
  15. Restart the server
  16. Start up your client Arma3.exe (Running the same branch as the server, (eg Stable or DEV) and you should then be able to see your server in the server browser (Filters are available to reduce the server list)
  17. Login to your server using the password you defined in CONFIG_Vanilla.cfg by typing "/" to open the chat window and then type (#login ADMINPASSWORD) followed by enter
  18. Once logged in you will be presented with a mission list, select one of the missions to start the game
  19. Prove the stability of your server by running BIS missions initially before you start adding user made content

File Locations

Some files are automatically created when you use certain commandline parameters Some files have to be created manually. If you have followed the instructions accurately, you will now have the following files and directories in addition to the clean install

  • d:\Games\Arma3\A3Master\ Users\Administrator\Administrator.Arma3Profile (Difficulty settings)
  • d:\Games\Arma3\A3Master\ Users\Administrator\Administrator.vars.Arma3Profile (Some binarised content which you cannot edit)
  • d:\Games\Arma3\A3Master\ Users\Administrator\Arma3.cfg (Bandwidth settings)
  • d:\Games\Arma3\A3Master\ MPMissions\ This is where custom made mission.pbo's need to be placed)
  • d:\Games\Arma3\A3Master\ arma3.rpt (Debug Log, automatically created every time the arma3server.exe is started)
  • d:\Games\Arma3\A3Master\ CONFIG_Vanilla.cfg (Manually created)
  • d:\Games\ArmA3\A3Files\ ArmA3_Steam_updater.cmd (Manually created)
  • d:\Apps\Steam\

Port Forwarding

Arma 3 uses the same default ports as Arma 2 with the addition of 2 steam ports. So if you intend running A2 and A3 servers on the same machine, you need to edit the ports used Default ports are all UDP and as follows

  • 2302 (Arma3 Game port)
  • 2303 (Server reporting)
  • 2305 (Von)
  • 8766 (Steam port)
  • 27016 (Steam query port)

To define the ArmA3 Game port used, state -port= **** in your command line arguments (Where *** is the new initial Arma 3 Game eg 2302)

and to define your Steam ports add the following lines to your CONFIG_Vanilla.cfg (editing the actual port numbers as required) 

// STEAM
steamport=8766;
steamqueryport=27016;

If you are running multiple servers, i would suggest the following format

SERVER 1
2300 UDP (steamport)
2301 UDP (Steam query port)
2302 UDP (used for game)
2303 UDP (used for server reporting)
2304 UDP (? no information available for this port useage)
2305 UDP (used for VoN transmissions)
so open ports 2300-2305
and leave at least 10 ports between the next server set

SERVER 2
2320 UDP (steamport)
2321 UDP (Steam query port)
2322 UDP (used for game)
2323 UDP (used for server reporting)
2324 UDP (? no information available for this port useage)
2325 UDP (used for VoN transmissions)
so open ports 2320-2325
leave at least 10 ports then repeat the process for No3 server etc

Configuring for stable or Dev branch

Edit the ArmA3_Steam_Updater.cmd as defined below then run it

  • To select Development version
SET A3BRANCH=107410 -beta development
  • To roll back to stable build
SET A3BRANCH=107410 -beta

Important Feature Since 12th March 2013 the development branch and the stable branch versions are no longer compatible. this means:
Only DEV clients can connect to a DEV server
Only Stable clients can connect to stable servers

Multiple Server configuration

There are various methods available to run multiple Dedicated Arma 3 servers on the same box. Each server instance requires

  • Its own unique set of ports
  • Its own profile
  • Its own config

This Post explains it more in depth

Each method has some pro's and cons To select the preferred methodology that suits your requirements you need to have considered the following

  • The useage of the "Keys" folder
  • The useage of the "MpMissions" folder
  • Available Hard drive space
  • Update management

METHOD 1

see THIS POST for more detailed information This is copy of the master install into a different directory As may times as you have space for

Pros

  • Most robust
  • Unique MpMissions folder
  • Unique "keys" folder
  • Allows ability to run seperate instances of different branches of the game, (E.g Dev or Stable)

Cons

  • Uses more drive space
  • Requires more effort to create and automate the updating process

METHOD 2

This uses 1 master install folder and has renamed arma3server.exe's in sub folders of the master see THIS POST for more detailed information

Pros (Compared to Method 1)

  • Uses less space than Method 1
  • Updating will be easier

Cons (Compared to Method 1)

  • Not very Robust
  • Shares MpMissions folders with all the other exe's (Will create a very cluttered MpMissions folder and allows admins to select addon required missions for a mod this server instance isn't running
  • Shares "keys" folder with all other exe's (This can cause an issue when running various differing -mod servers)
  • Will not allow you to run seperate instances of different branches of the game

METHOD 3

This is a hybrid of method 1, in that it is essentially a "Virtual" copy of the master install in a different directory the difference being that many folders are sim linked to the initial Master directory simlink GUI:

Pros (Compared to Method 1)

  • Uses less drive space (As you wont have multiple copies of the addons folder)
  • Allows for unique MpMissions folder if desired
  • Allows for unique "keys" folder if desired
  • Updating will be easier

Cons (Compared to Method 1)

  • Requires more effort to initially create the simlinks and directories
  • Will not allow you to run seperate instances of different branches of the game at the same time, (E.g Dev or Stable)

METHOD 4

You could of course mix n match all 3 methods to suit your specific requirements


Dedicated Server & Client configuration

The only known issue, is to make sure you start the server up before you start the steam client Failing to do this causes steam port issues and your client will not be able to connect to the server

Headless Client

--JacmacBrian (talk) 22:14, 23 February 2014 (CET)

A Headless Client can be used by missions to offload AI processing to a dedicated client, freeing up the dedicated server process from most AI processing. Thus more AI units can be spawned and the server process will be able to dedicate most of it's processing towards communication with the clients. For a Headless Client/Dedicated Server to function together efficiently, they both need to be connected to each other via extremely low latency and high bandwidth. Effectively, they need to be on the same LAN at least, but preferably running on the same computer.

Setup and Execution

  • Headless Client for ARMA 3 requires a valid active Steam account logged in to function (Dwarden Post)
  • A Headless Client is simply Arma3.exe run from the command line with parameters, for example:
arma3.exe -connect=localhost -port=2444 -client -nosound -password=some_server_password -name=HC -profile=HC -mod=@CBA_A3;@blah;@blah;@blah

In the example above, the headless client is running on the same host as the dedicated server. It uses a profile called HC and connects to the server with a password as required by the server (the password is for password protected servers, optional). The server in this example is running on port 2444, alter this to the port of your server.

  • The Headless Client profile needs to be created like any other profile in Arma 3 (Note: It is best if you name this profile HC)

No configuration of the profile is necessary, but after creation, edit HC.Arma3Profile located in C:\Users\yourusername\Documents\Arma 3 - Other Profiles\HC and add this line: 

battleyeLicense=1;

Alternatively, you can use the full Arma 3 client to connect to any multiplayer server with BattlEye enabled and accept the BattlEye License Agreement, which will do the same thing as manually editing HC.Arma3Profile.

Once the profile is ready, copy the profile directory to C:\Users\yourusername\Documents\Arma 3 - Other Profiles on the server (if the profile was not created on the server). If the profile was created on the server or is not going to run on the server and is already on the computer it is going to run on, then it is ready to go.

  • If the Headless Client is on the server, the server's cfg should be modified (e.g. A3Server.cfg):
localClient[]={127.0.0.1};
battleyeLicense=1;

Dwarden suggests that battleyeLicense=1; be in the server's config, but it is unclear whether this is actually necessary. Dwarden Post

localClient[]=x.x.x.x will allow the server to communicate with the Headless Client using unrestricted bandwidth. If the Headless Client is on the same LAN, but a different address, or there are multiple headless clients, they can be added in a similar way: 

localClient[]={127.0.0.1, 192.168.1.10};

Headless Client on a Dedicated Server Notes: If the Arma 3 Headless Client and a Arma 3 Dedicated Server are running on the same Windows computer (VM or physical), it may be beneficial to set processor affinity to prevent execution intensive threads from being scheduled across the same (v)CPUs. The operating system will generally schedule threads efficiently, but manual CPU allocation is possible. This can be achieved by right-clicking on the process (e.g. Arma3Server.exe(*32)) in the processes tab of the Windows Task Manager and selecting Set Affinity.... Be aware that on a physical intel CPU, the odd numbered CPUs are hyperthread instances.

Support & Troubleshooting

Known Issues

  1. My server has 2500ms ping in server browser (This is caused by running the steam client as Non Administrator) see http://feedback.arma3.com/view.php?id=9374
  2. MaxMsgSend default is 128, higher values can create Desync problems if the server's available processing and/or bandwidth can not support the higher value
