NETHOGS(8)						      System Manager's Manual							NETHOGS(8)

NAME

       nethogs - Net top tool grouping bandwidth per process

SYNOPSIS

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

DESCRIPTION

       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.

   Options
       -d     delay for refresh rate.

       -h     display available commands usage.

       -p     sniff in promiscious mode (not recommended).

       -t     tracemode.

       -V     prints Version info.

       device(s) to monitor. By default eth0 is being used.

INTERACTIVE CONTROL

       m      cycle between display modes (kb/s, kb, b, mb)

       r      sort by 'received'

       s      sort by 'sent'

       q      quit
