displays a statistical summary of all attached interfaces, and the
detailed interface statistics, which shows  more statistical and

>  The second menu option displays a list of
  attached network interfaces, and some general
  packet counts. Specifically, it displays counts of IP, non-IP, and bad
  IP packets (packets with IP checksum errors). It also includes an
  activity indicator, which shows the number of kilobits and packets the
  interface sees per second. All figures are for incoming and outgoing
  packets. (Again, considering promiscuous
  mode for LAN interfaces, which simply causes the machine
  to intercept all packets). This is useful for general monitoring
  of all attached interfaces. If byte counts and
  additional information are needed for a specific interface, the <I
CLASS="EMPHASIS"
>Detailed
  interface statistics</I
> option is also available.</P
><P
>  The activity indicators can be toggled between kbits/s and kbytes/s with
  the <I
CLASS="EMPHASIS"
>Activity mode</I
> configuration option.</P
><P
>  The general statistics window will dynamically add new entries
  as packets from newly-created interfaces (e.g. new PPP interfaces) are
  intercepted. Long lists can be scrolled with the Up, Down, PgUp, and
  PgDn keys.</P

  When started from the command line, the log filename and log interval can be

  parameters respectively.  See the <A
