serverDZ.cfg is the main DayZ server config file: it holds the server name, passwords, player slots, map, time speed, view and voice rules, and security options. On FREAKHOSTING you edit it on the Game settings page, which groups every option into Server, Gameplay, Time and light, Security and limits and Mods. The server reads the file when it starts, so restart after saving.
How the Game settings page works
- Search settings finds an option by name; All / Changed shows only what you changed.
- Presets fill in several settings at once: Hardcore (first person only, no crosshair, darker nights) and Casual (third person on, brighter nights, faster days). Nothing is saved until you review and save.
- Show advanced settings (8) shows the Security and limits group.
- Badges: STARTUP means the value is saved as a startup variable, CAREFUL marks options that can stop the server or hide your world, and Default resets one option.
- Review and save shows exactly what will change; Discard throws your edits away.
