.SH DESCRIPTION
\fBiftop\fP listens to network traffic on a named \fIinterface\fP, or \fBeth0\fP
if none is specified, and displays a table of current bandwidth usage by pairs
of hosts. \fBiftop\fP must be run with sufficient permissions to monitor all
network traffic on the \fIinterface\fP; see \fBpcap\fP(3) for more information,
but on most systems this means that it must be run as root.
\fBiftop\fP listens to network traffic on a named \fIinterface\fP, 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.
\fBiftop\fP must be run with sufficient permissions to monitor all network
traffic on the \fIinterface\fP; see \fBpcap\fP(3) for more information, but on
most systems this means that it must be run as root.
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
