Click on the Configuration files button on your control panel and press the text editor option on the starbound_server.configPar file
Find "allowAdminCommandsFromAnyone".
Set it to false: if it is not already.
"allowAdminCommandsFromAnyone" : false,
Find "anonymousConnectionsAreAdmin".
Set it to false: if it is not already.
"anonymousConnectionsAreAdmin" : false,
Find "serverUsers".
Add yourself as admin. The usernames can be anything and don't have to be your Steam name or character name. Example:
"serverUsers" : {
"yourname" : {
"admin" : true,
"password" : "yourpassword"
}
},
Note: You will not be able to execute admin commands right away. You'll still have to /admin yourself when in-game, but other users will not be able to do the same if you haven't set them to be allowed to.
After making changes to the starbound_server.configPar file with the text editor do not use the Easy Configurator otherwise your text editor changes will be overwritten and removed!
