Garry's Mod server settings: every option explained

Garry's ModUpdated Oct 5, 20265 min read

These are the options on the Settings, Game Settings page of a PlayNHost Garry's Mod 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
MapThe map the server loads when it starts. Maps that come with a Workshop collection work here too - type the map's own name, which is often not the title shown on its Workshop page.letters, numbers, dashes and underscoresgm_flatgrass
Steam Game Server TokenOptional. A Game Server Login Token you create against your own Steam account. It gives the server a permanent identity in the public server browser and better placement there. Your server is listed and playable without one, and Workshop addons download without one. A wrong token is worse than none: the Steam login then fails outright, VAC turns off, the server drops out of the list, and because this server type watches for the Steam login line the panel sits at Starting forever while the game is actually running.exactly 32 letters and numbers, or emptyempty
Workshop CollectionThe id of a Steam Workshop collection - the number at the end of the collection's page address. Everything in the collection is downloaded and loaded every time the server starts, and players get it when they join. It has to be a collection: a single addon's id loads nothing at all, so make your own collection and put that addon in it. Leave empty for a server with no addons.a number of at least 1empty
GamemodeThe gamemode the server runs, written as its short folder name in lowercase - sandbox, terrortown, darkrp. A gamemode from the Workshop needs its addon in your Workshop collection and its folder name here, which is not the title on its Workshop page.letters, numbers, dashes and underscoressandbox
TickrateHow many times a second the server updates the world. Higher can feel smoother to players but uses more CPU, and pushing it high on a full server usually causes lag rather than curing it. 22 suits most servers.a number from 1 to 10022
Lua RefreshLets the server reload Lua files while it is running, so addon changes take effect without a restart. Useful while building a gamemode, best left off on a busy server.on or offoff
Auto UpdateCheck for a game update each time the server starts, so your server stays on the build players are running. Garry's Mod updates can break addons, which is the one good reason to turn this off - but a server on an old build cannot be joined by anyone whose game has already updated.on or offon
Server nameThe name players see in the in-game server browser and on the scoreboard. No spaces, asterisks or question marks: the startup line hands this to the game as a bare word, where a space ends it and the rest is dropped and a * or ? is expanded as a filename pattern, so join words with - or _.up to 64 characters, no spaces, double quotes, backslashes, asterisks or question marksPlaynHost-GMod-Server
RCON passwordSet this to run admin commands from an RCON tool while the server is up. Leaving it empty keeps remote administration switched off, which is the safer setting. This is not the server join password, and it should not be the same one. Letters, numbers, dashes and underscores only.1 to 30 characters, letters, numbers, dashes and underscoresempty
Max Players (read only)The most players allowed on your server at once. This comes from your plan - move to a bigger plan to raise it.set by your plan or the serverset by your plan

Good to know

  • These settings are read when the server starts, so restart the server after changing any of them. These guides describe the standard Garry's Mod server type. The Garry's Mod - Reworked type has different settings, and changing server type deletes the server's files by default, so back up first.
  • 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.
  • To open the page, follow How to set up your Garry's Mod server or How to change your server settings.
