iftop displays network usage by connection. The default display shows the connection endpoints (port numbers may be toggled using the p key), with data transfer volumes displayed in numeric format and as a horizontal bargraph using reverse video. Various keys provide control over the display; pressing ? displays a help page listing these keys. iftop also provide command-line options for traffic filtering and interface selection.
The information displayed by iftop is detailed and easily understood. When an application is hogging your network bandwidth, iftop can be an invaluable tool -- though you may need to also use netstat -p to determine which process is behind a particular connection.
