Configure your DayZ server (serverDZ.cfg)

The serverDZ.cfg file holds every server-side DayZ setting: public name, admin password, player password, number of slots, missions and game parameters. It is read at startup via the -config= parameter.

Cause / The problem

A poorly edited serverDZ.cfg prevents the server from starting or makes it impossible to connect (wrong port, forgotten password, mission not found). Players can see the server but cannot join it if the network settings are wrong.

Solution

1. Locate serverDZ.cfg in the panel (Files tab), usually at the /serverfiles root.
2. Main settings:

   hostname = "My DayZ Server EU | onesubnet";
   password = "";
   passwordAdmin = "AStrongPassword";
   maxPlayers = 60;

   Leave password empty for a public server. passwordAdmin grants access to in-game admin commands via #login.
3. Network and mission configuration:

   steamQueryPort = 2303;
   port = 2302;
   class Missions {
       class DayZ {
           template = "dayzOffline.chernarusplus";
       };
   };

   The template points to the mission folder (Chernarus, Livonia, etc.).
4. Enable useful logs:

   logAverageFps = 30;
   logPlayers = 30;
   logMemory = 30;

5. Check that the startup line in the panel contains:

   -config=serverDZ.cfg -port=2302 -profiles=profiles -dologs -adminlog

   Without -config=, the server falls back to generic default values.
6. Restart and connect. In game, type #login AStrongPassword in the chat to become admin. The commands #restart, #shutdown, #lock, #unlock become available.
7. To change the map, edit the template (e.g. dayzOffline.enoch for Livonia) and restart.

Back up serverDZ.cfg before any major change. A missing comma in the class Missions {} syntax causes a silent startup failure — check the logs in /profiles.
