DayZ server settings: every option explained

DayZUpdated Oct 5, 20268 min read

These are the options on the Settings, Game Settings page of a PlayNHost DayZ server, taken from the panel's own definitions. Rows marked read only are set by your plan or the server and cannot be changed.

All settings

SettingWhat it doesAllowedDefault
Automatic UpdatesQuickly checks for any server or mod updates on startup, and updates if necessary.on or offon
Server NameName of the server that will appear in the server list.up to 64 characters, no line breaksDayZ Server
Server PasswordPassword required to join the server. Leave blank to have no password.up to 20 characters, letters, numbers, dashes and underscoresempty
Admin PasswordPassword to log in as an admin on the server.up to 20 characters, letters, numbers, dashes and underscoresempty
RCON PasswordThis password is used to authenticate third parties to access server controls via RCON.up to 20 characters, letters, numbers, dashes and underscoresempty
Modlist File (Exported from DayZ Launcher)Optional. The file name of a modlist.html exported from the DayZ Launcher and uploaded to your server's root folder. When the file is present and valid, every mod it lists is added to the client-side mod list automatically. Must be a plain file name with no directory path - for example: modlist.htmlletters and numbers and these symbols: _ . -modlist.html
Steam Workshop Mods (Client-Side)Not currently available: downloading a Workshop mod needs a Steam account that owns DayZ itself, and the account this server installs from only owns the DayZ Dedicated Server tool, so a mod ID here will fail to download rather than load. A vanilla server works normally without this. Mods to load, written as a semicolon-separated list of @-prefixed Steam Workshop IDs. Example: @1559212036;@1564026768 The ID is the number at the end of a mod's Workshop URL (steamcommunity.com/sharedfiles/filedetails/?id=1559212036). Every time the server starts, these mods are downloaded and updated, and each mod's .bikey files are copied into your keys/ folder so players are allowed to connect.mod folder names that start with @, separated by semicolonsempty
Verify SignaturesChecks that connecting players are running mod files that exactly match the server's. Players whose mod files have been altered or are out of date are refused. Choose 2 to check mod signatures. This is the recommended setting and the only level of checking DayZ supports. Choose 0 to turn checking off. Only useful while working out why a mod will not load, because it lets players connect with modified files. Change it back when you are done.one of: 0, 22
Enforce Game VersionWhen ON, the server will allow the connection only to clients with same the version as the server.on or offon
Disable VoNWhen ON, will disable Voice over Network (voice chat) in the server.on or offoff
VoN QualityVoice over Network codec quality; the higher the better. (Values 0-30)a number from 0 to 3020
Disable Third PersonWhen ON, will disable third person view while on the server.on or offoff
Disable CrosshairWhen ON, will disable the crosshair from being visible while on the server.on or offoff
Disable Personal LightWhen ON, will disable a personal light positioned above all clients during the night time while on the server.on or offon
Darker NightsWhen ON, will make nights darker (more accurate nights, but hard to see without a light).on or offoff
Persistent TimeThe actual server time is saved to storage, so when ON, the next server start will use the saved time value.on or offoff
Time MultiplierThis is a time multiplier for in-game time (ie. 12 would move a full 24-hour day in-game 12 times faster, making it last 2 hours "in real life"). (Values: 0-24)a number from 0 to 2412
Night MultiplierThis is an additional multiplier to either speed up or slow down nights in-game. It is multiplied with the "Time Multiplier" variable to get it's final multiplier for night time speed. (Values: 0.1-64.0)a number from 0.1 to 641
Make Mod Files LowercaseEvery mod that is set to be loaded will have its folder and files changed to lowercase (to prevent errors). It is recommended to enable this for one server boot after copying a mod from a Windows machine to the server, or if mods seem to not be loading.on or offoff
Validate Server FilesValidates all server files when Automatic Updates is ON. Note: This will significantly increase server startup times, so it is recommended to only enable this when needed.on or offoff
Server-Side Only ModsNot currently available: downloading a Workshop mod needs a Steam account that owns DayZ itself, and the account this server installs from only owns the DayZ Dedicated Server tool, so a mod ID here will fail to download rather than load. A vanilla server works normally without this. Mods that run on the server only and that players do NOT need to install to connect. Same format as the client-side mod list: a semicolon-separated list of @-prefixed Steam Workshop IDs or uploaded folder names. Example: @1234567890;@MyServerMod These are downloaded and updated on start exactly like client-side mods, and are passed to the game with -serverMod=.mod folder names that start with @, separated by semicolonsempty
Extra Startup ParametersExtra command-line flags handed to the DayZ server when it starts, separated by spaces. The defaults switch on the logs most admins want: -dologs writes the general server log, -adminlog records player connections and admin actions, -netlog records network traffic, and -freezecheck restarts the server if it stops responding. Removing one of these stops the matching log being written. Leave this as it is unless you know you need a particular flag. Bohemia lists every supported launch parameter on the DayZ community wiki: https://community.bistudio.com/wiki/DayZ:Server_Configuration#Launch_Parameterstext-dologs -adminlog -netlog -freezecheck
Steam Query Port (read only)UDP port for Steam server list features. Helps the server be visible in the client server browser.set by your plan or the serverassigned to your server
Max Players (read only)Maximum number of players allowed to join the server.set by your plan or the serverset by your plan
RCON Port (read only)The port BattlEye RCON listens on, so admin tools such as BattleMetrics can manage your server remotely. This port is assigned together with your server and cannot be changed here. Use it with your RCON password when you connect an admin tool.set by your plan or the serverassigned to your server

Good to know

  • Settings are written into the server's configuration when the server starts, so restart the server after changing them, and change them in Settings, then Game Settings rather than by editing the configuration file, which is rewritten at every start. Max Players is set by your plan and cannot be edited.
  • The panel saves a value when you leave its field. If the value is not allowed, the panel tells you and keeps the old one.
  • Passwords and tokens are not listed with a value. Each server starts with one set for you, or with none, as the row says. Set a password before you invite players if you want a private server.
  • To open the page, follow How to set up your DayZ server or How to change your server settings.
