NAME

       iptraf - Interactive Colorful IP LAN Monitor

SYNOPSIS

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

DESCRIPTION

       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.

OPTIONS

       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

SIGNALS

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

FILES

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