Rust server settings: every option explained

RustUpdated Oct 5, 20265 min read

These are the options on the Settings, Game Settings page of a PlayNHost Rust 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
Server NameThe name of your server in the public server list.up to 60 characters, no double quotesA Rust Server
Modding FrameworkThe modding framework to be used: carbon, oxide, vanilla. Defaults to "vanilla" for a non-modded server installation.one of: vanilla, oxide, carbonvanilla
LevelThe world file for Rust to use.up to 20 characters, no double quotesProcedural Map
DescriptionThe description under your server title. Commonly used for rules & info. Use \n for newlines.no double quotesPowered by PlaynHost
URLThe URL for your server. This is what comes up when clicking the "Visit Website" button.a web addresshttp://playnhost.com
World SizeThe size of a procedural map, from 1000 to 6000. A bigger map takes longer to generate and uses more memory and disk. Changing this generates a new world on the next start; the old one stays on disk until you wipe.a number from 1000 to 60003000
World SeedThe seed the world is generated from. Leave it empty and Rust generates the same map for everyone, every time; set a number between 1 and 2147483647 for a world of your own. Changing it takes effect on the next start, and the old map stays on disk until you wipe, so change the seed as part of a map wipe rather than on its own.a number from 1 to 2147483647empty
Server ImageThe header image for the top of your server listing.a web addressempty
RCON PasswordThe password for RCON, which is how admin tools such as RustAdmin connect. Rust will not start without one: it crashes while writing its own startup line to the log, and the error it prints does not mention RCON. Letters, numbers, dots, dashes and underscores.up to 64 characters, letters and numbers and these symbols: . - _empty
Save IntervalSets the server’s auto-save interval in seconds.a number60
Additional ArgumentsExtra startup parameters, added after the ones this panel sets. Rust keeps the FIRST value it is given for a setting and ignores later ones, so repeating anything the panel already sets here - the ports, the player limit, the world size and seed, the server identity - has no effect. Verified on protocol 2633: a trailing +server.maxplayers 7 left the server at 50.textempty
Server LogoThe circular server logo for the Rust+ app.a web addressempty
Custom Map URLOverwrites the map with the one from the direct download URL. Invalid URLs will cause the server to crash.a web addressempty
Auto UpdateCheck for a game update each time the server starts. Rust patches on the first Thursday of the month and the client updates itself, so a server left behind cannot be joined at all. Leave this on unless you are deliberately holding a build; the check adds a few seconds to a start when there is nothing to download.on or offon
Max Players (read only)The maximum amount of players allowed in the server at once.set by your plan or the serverset by your plan
Query Port (read only)Server Query Port. Can't be the same as Game's primary port.set by your plan or the serverassigned to your server
RCON Port (read only)Port for RCON connections.set by your plan or the serverassigned to your server
App Port (read only)Port for the Rust+ App. -1 to disable.set by your plan or the serverassigned to your server

Good to know

  • Settings are read when the server starts, so restart after changing them. Changing World Size or World Seed generates a new world on the next start while the old map files stay on disk until you wipe. Back up first, because players start on an empty map; change them as part of a map wipe.
  • 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.
