The Command Line can be daunting for some users; NUTs - Network Utility Tools aims to make accessing tools usually run via the Command Line a more friendly process through a simple centralized GUI.
Instead of typing commands, click a button, and the action is performed. You can display and configure network settings with relative ease through this app. Run a TRACERT, PING an address, show/clear/export the ARP cache, modify DNS settings, MTU check, and more. The interface is organized and uncluttered, allowing easy execution of the desired command. The initial open screen retrieves network settings; you can change them from the dropdown menu at the top left.
NUTs - Network Utility Tools is a useful little app from a young developer. The source code is available over at his repository.
