How to set up a Garry's Mod server (workshop, DarkRP and fixes)

Garry's Mod servers can run Sandbox, DarkRP, TTT and many other game modes from the Steam Workshop.

Basic setup

1. Order a Garry's Mod server on our Discord.
2. Choose the game mode (gamemode) and starting map in your startup settings.
3. Edit garrysmod/cfg/server.cfg for hostname, passwords and rules.
4. Start the server and join with connect ip:port.

Add Workshop content

1. Create a Workshop collection with the addons you want.
2. Add the collection ID to your startup settings as host_workshop_collection.
3. Add a Steam Web API key as authkey so the server can download the addons.
4. Restart and let the server download everything.

DarkRP

Install the DarkRP game mode and the darkrpmodification addon, then change jobs, shipments and entities in the darkrpmodification files.

Common errors

• Pink and black checkerboard textures or ERROR models: the server is missing content, often from Counter-Strike: Source. Mount that content in mount.cfg.
• Workshop addons not downloading: the authkey is wrong or the collection is private. Make the collection public.
• Players stuck on a long download: set up FastDL with sv_downloadurl.
• Lag and high CPU: too many addons or heavy scripts. Remove unused addons and watch the console for Lua errors.
