[How To] Make a ARMA3 (Alpha) Dedicated Server

You can find the latest ArmA3 Dedicated Server tutorial here: https://community.bistudio.com/wiki/Arma_3_Dedicated_Server

Thanks @Nonov Urbizniz
Firstly I would like to welcome you to the new ARMA3 section on OpenDayZ!
Let's get started!
  1. The first thing you want to do is download ARMA3 Alpha on Steam.
  2. Once you have that done make a batch file named "@RUNSERVER.bat" or whatever you desire and save this inside of it.
    start arma3server.exe -port=2302 -config=cfg\config.cfg -world=Stratis
  3. Make a directory inside of the ARMA3 root folder and name it "cfg".
  4. Make a new file inside of that called "config.cfg" and paste this inside of it: http://pastebin.com/gft7pKDp
  5. After this is all setup you can run the server and have people join.
NOTE: If you want to run ARMA3 on your dedicated server and play at the same time, you will need to go into "offline" mode on your dedicated server and "online" mode on your PC where you will be playing it.

You can change these in the template = ; inside of the config.cfg
  • MP_COOP_m01.Stratis
  • MP_COOP_m02.Stratis

just copied my addons from from A2 into A3, enabled expansions and now can run any MPMission file on cherno or utes in A3 :D
The only problem with that is, is the size of your game folder.

ok will test it on my rootserver ^^ but the download is very slow!

aa ok server is up :D anyone got a working mpmission for downloading ?


We cannot play arma 3 when the server is open... :(

Yep...if it isn't fixed soon. I'm buying another copy...one thing I have read but not try it is to block steam and run steam in off-line mode then start the server. This of course only works if you have a dedicated box.

Steam in offline mode works here - I've got my steam account "signed in" but offline on my dedi and running the server, and can still sign in and play the client in online mode from my desktop.

Gosh the steam thing is pretty stupid, I leave steam installed in case I need to do a reinstall of dayz/arma2 but I sure don't leave it running.

So is there a big demand for servers? I got plenty of capacity on dedicated servers in LA but don't want to waste my time if there's already 1000s of servers on home PCs fired up.

First impression yesterday was that there is good demand. I'm running a fairly dumb little 20 player deathmatch mission that I threw together as a five minute proof of concept and its been packed.
