This tutorial was originally intended for setting up a server using the client arma3.exe and -server command line paramneter.
Since then, the ArmA3server.exe has been released, the tutorial has now been reworked to reflect that and only appertains to the useage of the ArmA3server.exe
The tutorial is intended for the lowest level of knowledge and skill, I make no apologies to those who think it is patronising. if you do, why are you reading a tutorial :j:

Updated Monday 27th May up to and including
This post


What you need
  • 1 Standalone Windows server (2008 or later) (Sound and GPU not required)
  • 1 Steam Account
  • Ownership of ArmA3
  • According to this THIS POST you can run the ArmA3server on Win2003 now
This is how you do it.

Take note.
There are additions within these instructions that you may not need, if you only intend running 1 instance of an Arma3 server on your machine
However, adding these superfluous commands and content will not be detrimental to single instance servers
Directory paths are all customisable but for the sake of this tutorial, all file examples and command lines used will be consistent with the tutorial instructions
  • Login as Administrator:
  • Install the latest version of DirectX
  • Create the following empty directories
    • D:\Apps\Steam
    • D:\Games\ArmA3\A3Master
    • D:\Games\ArmA3\A3Files
  • Download steamcmd.exe and save it to your targetted Steam install directory (E.g D:\Apps\Steam)
  • Run the steamcmd.exe. (This will download and install the required steam files to your custom steam directory)
  • Create an ArmA3_Steam_updater.cmd file, (Example shown below) and save it to D:\Games\ArmA3\A3Files
  • Run the ArmA3_Steam_updater.cmd file
  • 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)
  • Create a shortcut for the ArmA3Server.exe on the server desktop
  • 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)
    • "-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
  • Add firewall rules for the UDP ports (See below for -Port information)
  • 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)
  • Then start up your shortcut, check the server runs. (You will see a console pop up in your desktop after a few seconds)
  • Close the console window down, then you will need to edit the following files which will have been created
    • D:\Games\Arma3\A3Master\Users\Adminstrator\Administrator.Arma3AlphaProfile
    • D:\Games\Arma3\A3Master\Users\Administrator\Arma3Alpha.cfg
    • (See below for example files)
  • Restart the server
  • Start up your client Arma3 (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)
  • 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
  • Once logged in you will be presented with a mission list, select one of the missions to start the game
  • Prove the stability of your server by running BIS missions initially before you start adding user made content



Arma 3 Restarter.exe server monitor
***ArmA3 server using TA2DST Method A U-tube video tutorial by Kirkwood364 which uses Tophe's Arma 2 Dedicated Server Tool to administer and run an A3 server
(Links for all the files required are available in the 1st comment of his Utube video)

This addon, installed serverside only, allows redefining skill setting on both the server (and remotely to the clients). This fixes the issue of not being able to reset Skill and precision settings and makes the AI less lethal

This addon, installed serverside only, injects an additional section to the clients briefing. You can edit the userconfig file to state exactly what information you want in this section.
Typical useage
  • Your teamspeak details
  • Your web address
  • Server rules
TICKETS RAISED that need your Vote_


Edit the ArmA3_Steam_Updater.cmd and 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

This is possible and there are a few methods to accomplish this.
Each server instance requires
  • Its own unique set of ports
  • Its own profile
  • Its own config
This POST explains it more in depth

In addition 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

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

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 Comparison to Method 1
  • Uses less space than Method 1
  • Updating will be easier
Cons Comparison 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

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

Pros Comparison 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 Comparison 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)

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

LOCATION OF FILES (When setting parameters)

Just to clarify here is an example file structure and location of files if you set certain parameters

Command line entry: -profiles

NOTE: If running Firedeamon, the user will be "SYSTEM", for most other scenarios it will be "Administrator"
The below example is for Firedeamon.
Files automatically created during exe.start if they don't already exist are highlighted in Blue


d:\Games\Arma3\A3Master\MPMissions\ ? Think this was auto created can't remember

Command line entry: -config

if you then add a -config parameter as in the example below, you will need to manually create the file and edit it accordingly

Using this example will look for the file in the root directory of the virtual server it is for

You can also use a full path and place it wherever you want

In the "CONFIG_Vanilla.cfg, if you add the line
logFile = "A3Master.log"; 
The logfile will automatically be created as


Command line entry: -netlog
This will automatically create the following file

RE-LOCATING MPmIssions (For example to a dropbox)

To define a different location for your MpMissions, such as a drop box location, carry out the following steps.
  • Either Move your MpMissions to its new location or just delete it. (Don't leave a copy in the original location)
  • run cmd tool on your server to create the link, use "" around the directories
  • example mklink /J "D:\Games\Arma3\A3Master\mpmissions" "C:\Users\user\Desktop\Dropbox\mpmissions"

PORT FORWARDING (ArmA3) (Firewalls)

ArmA3 uses the same default ports as ArmA2 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 ArmA3 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)

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

  • 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

  • 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

What cannot be done
  • ArmA3 -server on Win 2003 0/s Apparently you can now, see THIS POST
  • BattleEye/Rcon is not currently supported
  • Skillenemy/Friendly PrecisionEnemy / Friendly values when changed seem to have no effect. (Server side addon available to fix this)
  • ****.ArmA3Alphaprofile defining...... difficulty="*****"; or difficultyMP="*****";eg "Veteran" has no effect, all missions will run in regular mode unless manually redefined in mission selection screen


Known Issues
  • My server has 2500ms ping in server browser (This is caused by running the steam client as Non Administrator) see
  • Server keeps crashing
  • Reports from Admins who have been running OFP/ArmA series servers for some time suggests that the A3 -servers are remarkably stable for such an early stage AlphA.
    Therefore the most likely reason for consistent crashes would be
    We are also in an ALPHA, so it is to be expected
    • Use of 3rd party content, eg user made missions or addons
    • Server not capable of handling the resources required, badly configured or underpowered
  • DirectX
    • Windows Web Server 2008 - Error message: arma3.exe - Entry Point Not Found.The procedure entry point CreateDXGIFactory1 could not be located in the dynamic link library dxgi.dll.
    • Reporting Post Solution Post
      Bug Tracker Ticket

      • Windows 2008 server with this issue, the following may resolve it
      • Nobody has yet reported being able to run a -server with 2003
      #noseekThis problem has been solved
      Our server original operating system: Windows Server 2008 Enterprise (Simplified Chinese) SP1

      Run steam and ArmA 3 Alpha occur same error message: ...CreateDXGIFactory1 could not be located in the dynamic link library dxgi.dll...

      First, download and install directx_11_redist,the problem persists

      Then upgrade Windows Server to SP2, still error... :cryy:

      Last, download and install Windows6.0-KB971512-x86,the problem is solved!:yay:

      For reference

  • ArmA2 and ArmA3 servers conflict if they use the same ports. on the same machine.
  • It can cause one of the servers to use a different port automatically which will not have been defined in your firewall outbound rules and therefore not visible to the outside world
    this is easily remedied by stating a different port number in your startup params, eg -port=2312 (Leave at least 10 ports between servers)
    So your target line would then look something like

    "D:\Games\ArmA3\A3Master\arma3server.exe" -port = 2312 -config=CONFIG_Vanilla.cfg

-Profiles is used to load and save files to a different directory to that of the initial root install
This would be used when you want to run a "copy" of the initial ArmA2 install as it will load configs and Mpmissions in that "Copied" folder
This is used to run multiple instances of A3 servers on the same machine.

Example -profiles command line entry: "-profiles=d:\Games\ArmA3\A3Master"


#eRazeri Here`s a nice little batch file that I created to auto-restart server if it has crashed:

::Made by eRazeri
@echo off
C:\Windows\System32\tasklist /FI "IMAGENAME eq arma3server.exe" 2>NUL | C:\Windows\System32\find /I /N "arma3server.exe">NUL
if "%ERRORLEVEL%"=="0" goto loop
echo Server monitored is not running, will be started now 
start "" /wait "D:\Games\Arma3\A3Master\arma3server.exe" -config=CONFIG_Vanillar.cfg "-profiles=G:Games\ArmA3\A3Master"  -world=empty
echo Server started succesfully
goto started
echo Server is already running, running monitoring loop
C:\Windows\System32\timeout /t 10
C:\Windows\System32\tasklist /FI "IMAGENAME eq arma3server.exe" 2>NUL | C:\Windows\System32\find /I /N "arma3server.exe">NUL
if "%ERRORLEVEL%"=="0" goto loop
C:\Windows\System32\taskkill /im arma3server.exe
goto start



Programs tab
  • d:\Games\Arma3\A3Master\Arma3server.exe
  • Working Directory: d:\Games\Arma3\A3Master
  • Parameters: -port=2302 "-profiles=d:\Games\Arma3\A3Master" -config=Config_Vanilla.cfg -world=empty

Auto Restart Script, although firedeamon will do this for you if configured correctly

#almaxkiller Ok I got Firedeamon working where it will automatically restart the server if it closes.
Create a batch file and name it "arma3servercheck.bat" using notepad or notepad+.
Place the following in it:
@echo off
tasklist | findstr /i arma3server.exe
if %errorlevel% neq 0 goto restart
goto end
start "" "server.bat"

Then create your "server.bat" file using the launch parameters of your choosing.
Example (this is what we are using to run our ARMA 3 Wasteland server):

NOTE: Both of these files MUST be saved in the same location as your ARMA3server.exe, otherwise you need to change the file directory to "arma3server.exe" in each. Also note that if you are using this process you should have exit on the last line of the server.bat otherwise you will come back to a messy server with a lot of cmd windows open (depending on how many times your server shut down).

In FireDeamon create a service with the arma3servercheck.bat file and have it have a start-up time of 60000ms and a pre-launch delay of 60000ms. Also in the "Upon Program Exit:" Have it set to Restart the Program at 60000ms. All of those settings are overkill I am sure, but it makes it were every minute the process runs to see if arma3server.exe is running, and if not starts it up. Hope this helps some people, and if anybody comes up with a better solution please let me know!

**Disclaimer: I run Linux in my household, I have Win7 installed on my game rig, but it is not the primary OS on that system. I wanted to build an A3 dedicated server, because that is just how I am.

So, in case there are people out there that have an Ubuntu (Linux) server and want to get a Windows server running to install Steam and A3, here's how I did it. I don't have a monitor attached to that server, so I had to do a little more work to be able to run it, it all works out in the end.

I have tested this on an Ubuntu 12.04 server (host system) with the IP address where I'm logged in as a normal user.

To install VirtualBox 4.1 on our Ubuntu 12.04 server, we open /etc/apt/sources.list...
sudo nano /etc/apt/sources.list
Add the following line:
deb precise contrib

Download the following
wget -q -O- | sudo apt-key add -

sudo apt-get update

Execute this command
sudo apt-get install linux-headers-$(uname -r) build-essential virtualbox-4.1 dkms
(The dkms package ensures that the VirtualBox host kernel modules are properly updated if the Linux kernel version changes.)

Get the extension pack
cd /tmp
sudo VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.1.18-78361.vbox-extpack

(Make sure you grab the latest version from the VirtualBox web site.)

Now we must add the user that will run VirtualBox (administrator in this example) to the vboxusers group:
sudo adduser administrator vboxusers
VirtualBox is now installed and ready to be used.

***Step by step: creating a virtual machine on a headless server***

Note that on the server machine, since we will only use the headless server, neither Qt nor SDL nor the X Window system will be needed.

On the headless server, create a new virtual machine:
VBoxManage createvm --name "A3Server" --ostype WindowsXP --register

Note that if you do not specify --register, you will have to manually use the registervm command later.

Note further that you do not need to specify --ostype, but doing so selects some sane default values for certain VM parameters, for example the RAM size and the type of the virtual network device. To get a complete list of supported operating systems you can use
VBoxManage list ostypes

Make sure the settings for this VM are appropriate for the guest operating system that we will install. For example:
VBoxManage modifyvm "A3Server" --memory 4096 --acpi on --boot1 dvd --nic1 nat

Create a virtual hard disk for the VM (in this case, 100GB in size):
VBoxManage createhd --filename "A3Server.vdi" --size 100000

Add an IDE Controller to the new VM:
VBoxManage storagectl "A3Server" --name "IDE Controller" --add ide --controller PIIX4

Set the VDI file created above as the first virtual hard disk of the new VM:
VBoxManage storageattach "A3Server" --storagectl "IDE Controller" --port 0 --device 0 --type hdd --medium "A3Server.vdi"

Attach the ISO file that contains the operating system installation that you want to install later to the virtual machine, so the machine can boot from it:
VBoxManage storageattach "A3Server" --storagectl "IDE Controller" --port 0 --device 1 --type dvddrive --medium /full/path/to/iso.iso

Start the virtual machine using VBoxHeadless:
VBoxHeadless --startvm "A3Server"

If everything worked, you should see a copyright notice. If, instead, you are returned to the command line, then something went wrong. Here's what mine shows, for an example:
anderson@primus:~$ VBoxHeadless --startvm "A3Server"
Oracle VM VirtualBox Headless Interface 4.1.24

VRDE server is listening on port 3389.

Connect via RDP, install your server OS and then follow the standard guide for installing an A3 dedicated server like the one on the BIS forums

I have a question regarding the server.cfg
What does the following commands really do in terms of server performance?

language="English"; (Ok I get this one)
adapter=-1; (I run without this fine, What bennifit is there form having it?)
MinBandwidth=800000; (Min ammount I can expect from my server I got this set to 20mbps)
MaxBandwidth=25000000; (Max ammount I got this set to 100mbps The max my server is rated for)
MaxMsgSend=384; (I know this links to the max ammount of messages the game can send in any refresh cycle, but what does increasing/de-creasing this have on server performance?)
MaxSizeGuaranteed=512; (I have seen threads that claim its best to increase to 1024, or to only drop to 124)
MaxSizeNonguaranteed=256; (This I have been told can be set to nothing less than 64 or it counts the packet as fragmented and causes problems with the server. And that a lower number on this one would be better but how low? There are other threads that say this is connected to the MaxSizeGuaranteed and should be set at aprox 50% of its value)
MinErrorToSend=0.003; (The lower the number the smoother things look through scopes or binoculars, But how low should this be set before it causes lag)
MaxCustomFileSize=100000; (This preset to 160kb and is obsolite and could be removed. ARAM 3 is hard coded to not allow any custom files larger than 50kb. I know because I have 8/9 of my .ogg files working, the only one that does not is exactly 51kb in size. The rest are 49kb and under)
serverLatitudeAuto=52; (these are just for the server location so i dont need to change them)

I have read up on many forums about these settings, not one has given a proper description of what each of these does, how it relates to the other functions and what effect they have on a running server. I have seen many people ask this exact question, and either no-body knows, or they are keeping it a guarded secret.

If your serverhost can not even install the mods you want maybe you should choose a different host?
If you have root access to your server you can maybe install the mods yourself?

Hey guys.

I have a question regarding saving the progress of a warfare mission. A friend of mine is hosting a dedicted server for a few of our friends on a seperate computer. When we stop playing he is generally shutting down his computer, because he doesn't want to let it run 24/7 just to keep the progress that we made. Is there any way to save the progress on his machine, so that when he reboots the server he can load it back up?

My guess after googleing a bit would be 'no', but I just wanted to ask, just to be sure.

Hows that related to how to run an Arma 3 server?

Instead, post here:
Arma 3 system requirements / upgrades / performance improvements


The info is outdated and since people (who have no idea how to properly post on a forum) keep digging this up with unrelated questions it is time to lock it and let it slip into the darkness of forgotten....
