Adding an Admin on your Rust server

You'll need to create a file called users.cfg the server does not automatically create one.
Upload this file directly to your server using SFTP to folder server/my_server_identity/cfg/
In the Command Center using your browser you can edit the file. Use the following on separated lines to set up either server owners or moderators. You will need the person's steamID64.

For the players you want to assign the owner admin role:
ownerid “64_bit_steam_id” “optional_user_name” “optional_reason”
For the players you want to assign the moderator role:
moderatorid “64_bit_steam_id” “optional_name” “optional_reason”

You will then need to restart your server in order for the changes to take effect.
