Server Config File – Arma 2
This article deals with the server.cfg, a configuration file which you can use to configure various game server settings such as the difficulty level, how many votes are needed, and welcome messages. etc.
The name server.cfg means nothing, and this file can be called anything. The real name is determined by the -config command line option when launching the dedicated server. There is no default name - when you do not specify the filename, no server configuration file is loaded.
Server Options
Parameter | Description | |
---|---|---|
passwordAdmin = "xyzxyz"; | Password to protect admin access. | |
password = "xyz"; | Password required to connect to server. | |
serverCommandPassword = "xyzxyz"; | Password required by alternate syntax of serverCommand server-side scripting. | |
hostname="My Server"; | Servername visible in the game browser. | |
maxPlayers = 10; | The maximum number of players that can connect to server. The final number will be lesser between number given here and number of mission slots (default value is 64 for dedicated server). | |
motd[]= {"Welcome to my server.", "Hosted in the net."}; | Two lines welcome message. Comma is the 'new line' separator. | |
admins[] = {"<UID>"}; | e.g. admins[]={"1234","5678"}; whitelisted client can use #login w/o password (since Arma 3 1.69+). See Logged In Admin | |
headlessClients[] = {"<IP>"}; | see Headless Client Settings | |
localClient[] = {"<IP>"}; |
Server Behaviour
Server Behaviour | Description | |
---|---|---|
voteThreshold = 0.33; | Percentage of votes needed to confirm a vote. 33% in this example. | |
voteMissionPlayers = 3; | Start mission-voting when X numberOfPlayers connect. 3 players in this example. | |
allowedVoteCmds[] = { {"kick", false, false, 0.75} }; | see Mission voting | |

kickduplicate = 1; | Do not allow duplicate game IDs. Second player with an existing ID will be kicked automatically. 1 means active, 0 disabled. | |
loopback = true; | Adding this option will force server into LAN mode. This will allow multiple local instances of the game to connect to the server for testing purposes. At the same time it will prevent all non-local instances from connecting. | |
checkfiles[]= {"dta\bin.pbo", "a10\config.bin"}; | Outdated - replaced by verifySignatures! Only use if you really understand what it does.
List of files to check for integrity with crc check. Possible to check pbo files or files inside pbos. Beware checking large files, which takes serious processing on the server and can cause various issues. | |
equalModRequired = 1; | Outdated - replaced by verifySignatures! Only use if you really understand what it does.
Clients require the exact same modfolder naming, order and amount as the server. 1 means active, 0 disabled. | |
upnp = true; | Default: false. Automatically creates port mapping on UPNP/IGD enabled router. This option allows you to create a server behind NAT (your router must have public IP and support UPNP/IGD protocol).
Read more Internet Gateway Device (IGD) Standardized Device Control Protocol . Warning: When enabled then this setting may delay server start-up by 600s (standard UDP timeout of 10 minutes) if blocked on firewall or bad routing etc. Thus in such case is recommended to disable it. | |

Comments
Enabling the persistence option will make missions that have either base or instant respawn keep on running after all players have disconnected. The other respawn types will not make a mission persistent. The kind of respawn a certain mission uses is set in its Description.ext.
If you do not include the regularCheck option or set regularCheck = ""; it will be activated automatically. The server checks the files from time to time by hashing them and comparing the hash to the hash values of the clients.
Server Administration
If you are not using BattlEye RCon, there could only be 1 server admin at any given time. There are two ways of becoming admin, through a vote or through login with authenticated credentials.
Voted In Admin
It is possible to become a server administrator through player voting process. Such admin has less abilities than logged in admin.
For example, voted in admin would be able to kick a player, but only logged in admin would be able to ban a player.
For more information on voting and voting configuration see page Server Voting.
Logged In Admin
To log in as admin, one is required to type in#login command followed by server password, which matches password defined in passwordAdmin param.
Since Arma2OA it is possible to add one or several user ids UIDs into admins[] server config parameter, which would allow listed users to log in as admin by simply typing #login without a password.
This presents several advantages for managing the servers. The server owner can have multiple admins selected from the community and doesn't have to provide each one with server admin password.
The adding and removing of UIDs is done on the server side which makes it easy to add and to remove admins if necessary. On the server, admins are handled on first come first served basis.
Here are the rules:
- If there is already a logged in admin on the server, the new admin will not be able to log in until previously logged in admin logs out
- If there is a voted in admin on the server, the logged in admin will override voted in admin and take admin role
- There is no difference between logged in admin that used admin password or logged in admin that was whitelisted with admins[] param
The logged in and voted in admins have different set of Multiplayer Server Commands available to them. See serverCommandAvailable for more information.

Mission rotation
One can set an automatic mission rotation. Without an admin, the server will automatically select a mission when at least one player is connected. Once the mission is done and if there are still players on the server, it will automatically switch to the next in the cycle.
Example:
class Missions
{
class TestMission01
{
template = MP_Marksmen_01.Altis;
difficulty = "veteran";
class Params {};
};
class TestMission02
{
template = MP_End_Game_01.Altis;
difficulty = "veteran";
class Params {};
};
class TestMission03
{
template = MP_End_Game_02.Altis;
difficulty = "veteran";
class Params {};
};
class TestMission04
{
template = MP_End_Game_03.Altis;
difficulty = "veteran";
class Params {};
};
};
Arma 3: Apex - mission collection
Mainly intended for MP campaigns. If the progress is defined in the MPMissions class, server administrator can simply add the whole campaign by adding campaign class into the server.cfg. See the example below.
config.cpp:
class MPMissions
{
class Apex
{
briefingName = $STR_A3_CoopCampaignName;
class EXP_m01
{
briefingName = $STR_A3_exp_m01_missionname;
directory = "a3\missions_f_exp\campaign\missions\exp_m01.tanoa";
};
class EXP_m02
{
briefingName = $STR_A3_exp_m02_missionname;
directory = "a3\missions_f_exp\campaign\missions\exp_m02.tanoa";
};
class EXP_m03
{
briefingName = $STR_A3_exp_m03_missionname;
directory = "a3\missions_f_exp\campaign\missions\exp_m03.tanoa";
};
};
};
server.cfg:
// MISSIONS CYCLE
class Missions
{
class Apex{};
};
Also the difficulty of the each mission can be overridden
class Missions
{
class Apex
{
class EXP_m01
{
difficulty = "veteran";
};
};
};
Dedicated client in Headless Client mode
Parameter | Description |
---|---|
localClient[]={"127.0.0.1", ...}; | to indicate clients with unlimited bandwidth and nearly no latency (https://dev-heaven.net/issues/62500), Available since Arma 2:OA build 99184 , including Arma 3 |
headlessClients[]={"127.0.0.1", ...}; | The server doesn't allow arbitrary connections from headless clients if you do not define the headless clients IPs. Multiple Connections and Addresses are allowed in the case of more than one Headless Client. |
More details at Headless Client
Arma 2: Operation Arrowhead & Arma 3 - STEAM ports configuration
Parameter | Description |
---|---|
steamPort = <number>; | default 2303, defines port for communication with STEAM services, needs to be unique for each dedicated server within one OS instance / network interface |
steamQueryPort = <number>; | default 2304, defines port for server's STEAM query, needs to be unique for each dedicated server within one OS instance / network interface |
Arma 3 - Mission white-listing
The following example shows only Zeus and Karts missions allowed e.g. via voting and mission select. Arma 3 MP Mission Names has a complete mission list.
missionWhitelist[] = {
"MP_COOP_m04.Stratis",
"MP_COOP_m05.Altis",
"MP_COOP_m06.Altis",
"MP_COOP_m07.Altis",

"MP_ZR_8_Karts02.Stratis",
"MP_bootcamp_01.VR",
"MP_Bootcamp_01.Altis",
};
Arma 3 - Forced difficulty
Enforces the selected difficulty on the server.
forcedDifficulty = "<difficultyClass>";
- If Recruit, Regular or Veteran is passed as the parameter, the particular difficulty options will be taken from data config, from the class CfgDifficultyPresets.
- If Custom will be passed as the parameter, the particular flags will be taken from CustomDifficulty class from server's profile (only Custom is saved to the profile).
- If mission cycle is defined in the server.cfg, the difficulty set in the mission cycle overrides the difficulty set by forcedDifficulty parameter.
Arma 3 - Analytics configuration
Parameter | Description |
---|---|
statisticsEnabled = <number>; | default 1, allows to opt-out of analytics for the server by using 0 |
Additional details
For hosting server behind NAT or firewall, please ensure gameport and STEAMports are forwarded and open!
Set the ICMP "echo reply" as allowed so the server is able return ping delay properly.
It's recommended to enable the NAT traversal (so called "Edge traversal" in Windows Firewall) for arma3server.exe, arma3.exe to better support clients/servers behind NAT.
Overriding mission params
On dedicated server unless you are an admin you cannot set mission options provided by mission maker via class Params. However as a server owner you can override default setting with your own. See Mission Parameters for more info
