DayZ:Server Configuration

This article deals with the configuration file which is used to configure various game server settings.

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 non is specified, the server won't launch due to the mandatory settings.

⚠

Is is highly recommended to use the graceful shutdown method to avoid negative side effects on player characters and the server storage saving. More information under DayZ: Server Messages

Configuration

Main Parameters

description = "Some description";   // Description of the server. Gets displayed to users in the client server browser, max length 255 characters
password = "";						// Password to connect to the server
passwordAdmin = "";					// Password to become a server admin

enableWhitelist = 0;				// Enable/disable whitelist (value 0-1)

disablePrioritylist = false;		// Disables usage of priority.txt (default: false)

maxPlayers = 60;					// Maximum amount of players

verifySignatures = 2;				// Verifies .pbos against .bisign files. (only 2 is supported)

forceSameBuild = 1;					// When enabled, the server will allow the connection only to clients with same the .exe revision as the server (value 0-1)

disableVoN = 0;						// Enable/disable voice over network (value 0-1)
vonCodecQuality = 20;				// Voice over network codec quality, the higher the better (values 0-20)

disable3rdPerson = 0;				// Toggles the 3rd person view for players (value 0-1)
disableCrosshair = 0;				// Toggles the cross-hair (value 0-1)

serverTime = "SystemTime";			// Initial in-game time of the server. "SystemTime" means the local time of the machine.
									// Another possibility is to set the time to some value in "YYYY/MM/DD/HH/MM" format, e.g "2015/4/8/17/23".

serverTimeAcceleration = 1;			// Accelerated Time - The numerical value being a multiplier (0.1-64).

									// Thus, in case it is set to 4 and serverTimeAcceleration is set to 2, night time would move 8 times faster than normal.
									// An entire night would pass in 3 hours.

serverTimePersistent = 0;			// Persistent Time (value 0-1) - The actual server time is saved to storage, so when active, the next server start will use the saved time value.

guaranteedUpdates = 1;				// Communication protocol used with game server (use only number 1)

loginQueueConcurrentPlayers = 5;	// The number of players concurrently processed during the login process.
									// Should prevent massive performance drop during connection when a lot of people are connecting at the same time.

XML Configuration

<jobsystem globalqueue="4096" threadqueue="1024">
	<pc maxcores="4" reservedcores="1" />
	<!--
		maxcores - maximum number of CPU cores which will be used for jobsystem
		reservedcores - number of CPU cores which will be used for other threads

		number of worker threads is then "maxcores - reservedcores", but still at least one worker thread is allocated

BattlEye Configuration

The config file BEServer_x64.cfg needs to be in the same folder as BEServer_x64.dll. The location of this folder can be customized via the startup parameters -bePath and -profiles.

Supported parameters:

• RConPassword MyPassword - Sets the password for the connection of the RCon tool (remote connection admin tool like BEC/Dart)
• RestrictRCon 1 - Enables/Disables RCon functions (kick/ban/connection restrictions)

Launch Parameters

Run the DayZServer_x64.exe via the batch file, shortcut with parameters or other options.

Supported parameters:

• -config=serverDZ.cfg - Selects the Server Config File
• -port=2302 - Port to have dedicated server listen on
• -profiles=%userProfile%\Documents\DayZServer – Path to the folder containing server profile. By default, server logs are written to the server profile's directory. Logs/dumps/etc will be created there, along with BattlEye/BEC/Rcon related files
• -mission= - Defines the mission used by the server
• -doLogs - Enables all log messages in the server RPT file
• -adminLog - Enables the admin log
• -netLog - Enables the network traffic logging
• -freezeCheck - Stops the server when frozen for more than 5 min and create a dump file
• -filePatching - Ensures that only PBOs are loaded and NO unpacked data.
• -BEpath= - Sets a custom path to the BattlEye files
• -cpuCount= - Sets the number of logical CPU cores to use for parallel tasks processing. It should be less or equal than the numbers of available cores.
• -limitFPS= - Limits server FPS to specified value (current max is 200) to lower CPU usage of low population servers.
• -mod=<string> - Loads the specified sub-folders for different mods. Separated by semi-colons. Absolute path and multiple stacked folders are possible.
• -serverMod=<string> - Loads the specified sub-folders for different server-side (not broadcasted to clients) mods. Separated by semi-colons. Absolute path and multiple stacked folders are possible.
• -storage= - Defines custom root folder for storage location.

ⓘ

It is possible to define a batch variable in the .bat file and use it in the server exe's startup configuration arguments, e.g:

set missionLocation=%userProfile%\Documents\DayZ\Stable\mpmissions\dayzOffline.enoch
...
DayZServer_x64.exe -mission=%missionLocation%

Priority Queuing

Specified users can be prioritized in the login queue, they will get on the first position, before the non-prioritized users.

Flagged users simply need to added to a priority.txt file, located in the root directory of the server install.
