Command line (CLI) network speed test for GNU/Linux or Mac OS servers, using libncurses to estimate network throughput between your server and wherever you are connecting from. Works on any client platform that has a terminal that supports curses (e.g. iOS, Android, Mac OS, Windows, Linux, etc).
Network speed is measured by writing screenfuls of random characters to the terminal, using the resulting framerate to estimate the throughput. It takes advantage of the implicit communication between the server and your terminal to measure network performance without any client software beyond the terminal you already have.
