When run, \fBiftop\fP displays, for each pair of hosts, the rate at which data
is sent and received averaged over 3, 15 and 60 second intervals. The direction
is sent and received averaged over 1, 5 and 20 second intervals. The direction
of data flow is indicated by arrows, <= and =>. In addition, a simple bar graph
shows the 15-second average. The pairs of hosts which consume the most bandwidth

shows the 5-second average. The pairs of hosts which consume the most bandwidth
are displayed at the top of the screen, and totals for all hosts are shown at
the bottom of the screen.
By default, \fBiftop\fP will look up the hostnames associated with addresses it
finds in packets. This can cause substantial traffic of itself, and may result
