Monitor Network Activity of Applications and Users from the Command Line (like Top does for processor)

Question

Is there a linux command, that works like "top" (like top does for monitoring processor utilization), but shows network activity of users and applications realtime?

I want something that shows everything going on, where I don't have to specify each and everything to get an overview. Anything like this?

Answer 1

Iptraf is pretty nice for live overviews, vnstat is a lightweight alternative for every-now-and-then statistics.

Answer 2

pktstat is a great cmdline utility; shows url paths etc

tcptrack is also good.

iptraf is also okay.

Answer 3

The best one I know of is ntop, but it display stats via a web interface on port 3000. Not sure if there's one that runs just via a terminal.
