       iptraf - Interactive Colorful IP LAN Monitor
       iptraf-ng { [ -f ] [ { -i iface | -g | -d iface | -s iface | -z
       iface | -l iface } [ -t timeout ] [ -B [ -L logfile ] ] ] | [ -h ]
       }
       iptraf-ng is an ncurses-based IP LAN monitor that generates
       various network statistics including TCP info, UDP counts, ICMP
       and OSPF information, Ethernet load info, node stats, IP checksum
       errors, and others.
       If the iptraf-ng command is issued without any command-line
       options, the program comes up in interactive mode, with the
       various facilities accessed through the main menu.
       These options can also be supplied to the command:
       -i iface
              immediately start the IP traffic monitor on the specified
              interface, or all interfaces if "-i all" is specified
       -g     immediately start the general interface statistics
       -d iface
              allows you to immediately start the detailed on the
              indicated interface (iface)
       -s iface
              allows you to immediately monitor TCP and UDP traffic on
              the specified interface (iface)
       -z iface
              shows packet counts by size on the specified interface
       -l iface
              start the LAN station monitor on the specified interface,
              or all LAN interfaces if "-l all" is specified
       -t timeout
              tells IPTraf-ng to run the specified facility for only
              timeout minutes.  This option is used only with one of the
              above parameters.
       -B     redirect standard output to /dev/null, closes standard
              input, and forks the program into the background.  Can be
              used only with one of the facility invocation parameters
              above.  Send the backgrounded process a USR2 signal to
              terminate.
       -L logfile
              allows you to specify an alternate log file name.  The
              default log file name is based on either the interface
              selected (detailed interface statistics, TCP/UDP service
              statistics, packet size breakdown), or the instance of the
              facility (IP traffic monitor, LAN station monitor).  If a
              path is not specified, the log file is placed in
              /var/log/iptraf-ng
       -f     clears all locks and counters, causing this instance of
              IPTraf-ng to think it's the first one running.  This should
              only be used to recover from an abnormal termination or
              system crash.
       -h     shows a command summary
        SIGUSR1 - rotates log files while program is running
        SIGUSR2 - terminates an IPTraf-ng process running in the
       background.
