CSS server configuration and override order
CSS server configuration and override order. Version-specific steps, checks, rollback, and upstream sources for Source 1.
Keep Counter-Strike: Source server settings in its documented configuration layer under cstrike/cfg, and verify the final value after a map load. A value written in server.cfg can be overridden later by a game-mode, map, or plugin config, so file presence alone is not proof of the active value.
Before you change anything
- A legitimate Steam installation or dedicated-server installation for Counter-Strike: Source.
- A backup of every file that will be changed.
- Access to the local client console or the dedicated-server console, as appropriate.
Version-specific procedure
- Back up the whole configuration directory and record the current startup command.
- Identify the base server config, game-mode/map config, autoexec layer, and plugin-generated configs used by this engine.
- Place one test setting in the documented operator override file, not a Valve-managed base file.
- Restart or change map as required by the documented execution order.
- Read the final value from the server console and search later configs for duplicate assignments.
Verify the result
- The value after map load equals the intended value.
- The setting exists in one operator-owned source of truth.
Rollback
- Restore the backed-up configuration directory and restart the server on a stock map.
Common pitfalls
- Do not edit Valve-managed game-mode files that an update can replace when an operator override file exists.
