Ground control is an automated network monitor written in go from scratch.
It features an arp scanner to monitor the presence of hosts in your local network and a speed test based on Mlab.
You can build ground-control from sources with the standard go build command.
In order to do so you have to install the golang toolchain, version 1.12 or newer.
go build
In order to perform ARP scan ground-control needs to access to the ARP table of your OS, you have to start it with administrative privileges.
Example on macOS:
sudo ./ground-control
sudo is required in order to access ARP table
