NAME         top

       iptraf - Interactive Colorful IP LAN Monitor

SYNOPSIS         top

       iptraf-ng { [ -f ] [ { -i iface | -g | -d iface | -s iface | -z iface
       | -l iface } [ -t timeout ] [ -B [ -L logfile ] ] ] | [ -h ] }

DESCRIPTION         top

       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

       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.

OPTIONS         top

       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

       -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

       -h     shows a command summary

SIGNALS         top

        SIGUSR1 - rotates log files while program is running
        SIGUSR2 - terminates an IPTraf-ng process running in the background.

FILES         top

        /var/log/iptraf-ng/*.log - log file
        /var/lib/iptraf-ng/* - important IPTraf-ng data files
