NAME

6       nethogs - Net top tool grouping bandwidth per process

SYNOPSIS

9       nethogs [-h] [-V] [-d] [-v] [-t] [-c] [-p] [-s] [device(s)]

DESCRIPTION

12       NetHogs is a small 'net top' tool. Instead of breaking the traffic down
13       per protocol or per subnet, like most such tools do,  it  groups  band‐
14       width  by  process - and does not rely on a special kernel module to be
15       loaded. So if there's suddenly a lot of network traffic, you  can  fire
16       up  NetHogs  and immediately see which PID is causing this, and if it's
17       some kind of spinning process, kill it.
