Arma 3 Local Server
Arridano Tillo
Hello. When I host a local ArmA 3 server via the server browser menu, my friends cannot join. I have set in my router that my PC can independently release all ports it needs and I have also released all ports separately for arma to be on the safe side (port: 2302 ...) but under which IP can the server be reached? I've tried sites like whatsmyip but my friends can't join at this address. I have an IPV6 address. I want to buy the new Vietnam Dlc when it is available and then play the co-op campaign and therefore I want to see how it works with the local servers.
In the past I have had problems letting people connect to a decidated server i was running on my PC while connecting to that server as a player as a client. None of my friends could connect to the server remotely but another PC could connect on the local nework. To solve the problem I just rand the mission as a 'player/server' and all was fine.
It is also best practice to add a dedicated MySQL localhost account with only access to the dayz_epoch schema. If someone gets access to your server, they can only affect that schema if they dig the login info out of the config files.
Worked great! Thanks :D But one last question; whenever I adjust something in the server PBO (Dayz Epoch Server -> @DayZ_Epoch_Server -> addons) it will stop me from joining in; if I use default it's fine. Or do I have to adjust the server pbo somewhere else?
Started ARMA 3 server on AMP, can see and connect to it via local network (within my home network) but cannot connect from outside my network. Have friends try to connect to it but server will just not appear somehow. This is not the case for other applications i have tested so far on AMP, ie: Teamspeak, Terraria, Starbound
Port forwarding rules should be correct. as the applications can get through as mentioned, Terraria and Teamspeak work just fine as people are able to connect through. Its just Arma causing this issue.
I cannot for the life of me follow the stuff in -Tutorial-How-to-run-ArmA3-on-a-dedicated-server . Most of that seems to be directed rightly enough at someone who's paid for a hosted server. I don't even have a D drive, I don't see "administrator", I just can't make sense of it.
Can someone please either point me to a thread which explains in simple terms how to set up a server on a local machine, OR just tell me. I can't believe it's as complicated as installing steam updaters and all the rest. I mean I have all that stuff already to play Arma in the first place.
This page contains useful information on how to install and configure an Arma 3 server and includes step by step guides of the install process. Also information on how to configure and run a server.The majority of directories and paths are customizable, however those defined are all consistent with the tutorial instructions.
If you cannot connect to server through server browser try to use "direct connect":this is a client side issue (doesn't mean other clients will have it too), reason for the issue for now unknown,I can say it is not related to: Windows services, Windows network settings, network routers, firewalls...
As a security best practice, create a user to run steam instead of running as root or an administrator.This way, if your Arma 3 server is compromised the attacker will find it more difficult to access the rest of the operating system.
At the Steam client shell, login with a valid Steam username and password.The Valve Developer Community Wiki recommends that you create a new Steam account for this.SteamCMD will cache the login credentials and anyone who gains access to your server will be able to log into the account used here.In addition, you cannot log into a single Steam account from two places at once. You do not need to have Arma 3 purchased on the Steam account used here to download the server.Therefore, you should create a new Steam account with no purchases only for use on this server.
The arma3server_x64 process will attach to the current terminal.If you are connected to the server over SSH, the server will stop when you disconnect.You can keep the server running using a terminal multiplexeer like GNU Screen or tmux.There are many tutorials online on how to use these programs to detach and reattach processes from and to a terminal.
If you regularly update your mods using, e.g. Arma3Sync, you will find that this will redownload any files/folders that have changed case every time you run it.The solution to this is to use a package called "ciopfs" - Case Insensitive On Purpose Filesystem. You should first run the "find . -depth..." command mentioned above on your mod folder.Then, make an empty directory outside of the mods directory, e.g. mods_caseinsensitive. You then mount the directory with:
Some files are automatically created when you use certain commandline parametersSome 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
Arma 3 uses the same default ports as Arma 2 with the addition of several ports. So if you intend running Arma 2 and Arma 3 servers on the same machine, you need to edit the ports used.Default ports are all UDP and as follows:
UPnP allows you to automatically create port forwarding on your router to bypass NAT (UPnP enabled routers are required).The functionality can be easily enabled in server config as described in the server.cfg page.
This is a hybrid of method 1, in that it is essentially a "Virtual" copy of the master install in a different directorythe difference being that many folders are symlinked to the initial Master directorysymlink GUI:
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 is 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.
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.
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.
This will allow the server to communicate with the Headless Client using unrestricted bandwidth. It is also required to add the adress to headlessClients[]= "x.x.x.x" ;.Multiple headless clients at different addresses can be added:
If the Arma 3: Headless Client and a 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 Hyper-thread cores.
It has been observed that although the Arma server and client processes will kick off multiple threads, the bulk of processing is used up by only one or two threads.For example, spawning 50 AI units does not generate 50 threads.There is one thread in the process that handles all of the AI units, irrespective of how many have been spawned.In this way, the ARMA server and client processes do not make maximal use of the processing capability found in modern processors and so AI counts do not scale easily.As such, faster CPU core speed is king and offloading the AI to multiple headless clients on the same computer will probably produce the best possible results for complex missions involving many AI units (albeit an expensive way to get the results).
I don't need the database stuff for just saving the current progress (where the AI is, what sectors they control, etc) on the server, do I? If I can load a saved campaign, how exactly do I do that? Whenever I run a mission I've saved, I only get the "Start" option not the "Resume/Restart" options.
You can enable regular saving in the ALiVE (Required) module. It comes with a health warning though - if you're running a big map with a lot of profiles and stuff going on, the ArmA engine can't handle the amount of data and could crash to desktop with an out of memory error. We highly recommend you set up on War Room for persistent missions.
The recommended approach, and the one a lot of us use for testing, is setting up a "local dedicated server". If your run arma3server.exe with the exact same mod line as your game but including @aliveserver as well, you can then join this from your normal game client.
Then you can add the details to War Room using your servername and IP address and benefit from all the persistence, maps, AAR and showing off your shiny stats on the profile, and make use of the automated performance data. Just be sure to check your IP address is the same each time you run it up (if you don't have a static IP from your ISP).
