Rustadmin is a free desktop application that you can download and use to run commands, view server information and much more without being logged into the server. This is perfect for server owners who want to know everything that's going on in their server and best manage it from a bird's eye view. Here's how you can set it up.
1. Download Rustadmin (free) from the official site.
2. Extract the downloaded zip and run RustAdmin.exe
3. In the top right, click connect, click OK, then click OK again. (You can set up a Steam API key if you wish to get more features).
4. In the configuration screen, enter your server's IP, port and RCON port from the server control panel. The, give it a name.
5. You'll now be able to run console commands, schedule commands, and do much, much more administration for your Rust server.
