server.cfg and users.cfg
Rust reads server.cfg at every start. Set max players, the RCON password and other options (convars) there. Admin and moderator rights go in users.cfg.
Rust has no startup page. The server name, description, map size and seed are managed in Wipes, not in server.cfg.
Where the files are
/server/rust/cfg/server.cfg/server/rust/cfg/users.cfg
In Files, open server, then rust, then cfg. If a file is missing, press New File inside cfg and use the exact name.
Edit server.cfg
- On Console, press Stop (recommended, so nothing overwrites your changes).
- Open
server.cfgin Files to edit it in the browser. - Add or change lines as
convar value. Put text values in quotes. - Save the file.
- Press Start. Changes apply only after a restart.
Example:
server.maxplayers 100
rcon.password "use-a-long-unique-password"
server.pve false
decay.scale 1
server.saveinterval 300
fps.limit 60
Lines starting with // are comments and are ignored.
Useful convars
| Convar | What it does |
|---|---|
server.maxplayers | Maximum number of players. More players need more CPU and memory, so choose a number your plan can handle. |
rcon.password | Password for RCON. Required to use remote tools. |
server.pve | true stops players from damaging each other. |
decay.scale | Speed of building decay. 1 is normal, 0 turns decay off, higher values make bases decay faster. |
server.tickrate | Server update rate. The default is fine for almost everyone: leave it alone. |
server.saveinterval | Seconds between automatic world saves. |
fps.limit | Caps the server frame rate. Lower values use less CPU. |
Gather rates, kits and teleports are not vanilla convars. They come from plugins.
Do not change server.ip, server.port, rcon.ip or rcon.port. FenixHost sets them to match the ports shown in Network in Settings.
users.cfg: owners and moderators
users.cfg lists the players with admin rights in game. Each line uses the player's 17-digit Steam ID (SteamID64):
ownerid 76561198000000000 "PlayerName" "owner"
moderatorid 76561198000000001 "PlayerName" "moderator"
Owners can use all console commands in game (F1). Moderators have fewer permissions. Restart the server after editing. These roles are separate from panel access: to let someone use the panel, add them under Users in Settings.
If a change does not apply
FenixHost sets some convars at startup, and the startup value may win over server.cfg. First check the file name and path, that you saved, and that you restarted. If it still does not apply, open a ticket with the convar and value you tried.
Other checks:
- Each line must be
convar value, with a space and no=. - Check the console right after starting: Rust reports unknown commands and errors there.
- If the server stops starting after an edit, remove your last changes or restore a backup.
- Fenix can read the console and propose a fix, and applies it only when you press Apply.
