Projects / constat


constat is an application that monitors, logs, and reports the activity of network connections present on a system. It reports sent/received traffic information for every live network device, giving you the option of displaying its output in units of kilobytes, megabytes, and gigabytes, along with the number of transmitted packets. It also includes a real time monitoring option based on a timer. Additionally, constat provides the option to view the socket table (local/remote IPs with ports they are binded to) for a specific protocol or all protocols at once. It does not require the X server.
