FTOP(8) IFTOP(8)
NAME
iftop - display bandwidth usage on an interface by host
SYNOPSIS
iftop -h | [-nNpbBP] [-i interface] [-f filter code] [-F net/mask]
DESCRIPTION
iftop listens to network traffic on a named interface, or on the first interface it can find which looks like an
external interface if none is specified, and displays a table of current bandwidth usage by pairs of hosts. iftop
must be run with sufficient permissions to monitor all network traffic on the interface; see pcap(3) for more infor‐
mation, but on most systems this means that it must be run as root.
By default, iftop will look up the hostnames associated with addresses it finds in packets. This can cause substan‐
tial traffic of itself, and may result in a confusing display. You may wish to suppress display of DNS traffic by
using filter code such as not port domain, or switch it off entirely, by using the -n option or by pressing n when
the program is running.
By default, iftop counts all IP packets that pass through the filter, and the direction of the packet is determined
according to the direction the packet is moving across the interface. Using the -F option it is possible to get
iftop to show packets entering and leaving a given network. For example, iftop -F 10.0.0.0/255.0.0.0 will analyse
packets flowing in and out of the 10.* network.
