nethogs - Net top tool grouping bandwidth per process
nethogs [-d] [-h] [-p] [-t] [-V] [device(s)]
NetHogs is a small 'net top' tool. Instead of breaking the traffic down
per protocol or per subnet, like most such tools do, it groups
bandwidth by process - and does not rely on a special kernel module to
be loaded. So if there's suddenly a lot of network traffic, you can
fire up NetHogs and immediately see which PID is causing this, and if
it's some kind of spinning process, kill it.
-d delay for refresh rate.
-h display available commands usage.
-p sniff in promiscious mode (not recommended).
-V prints Version info.
