NAME
       iptraf - Interactive Colorful IP LAN Monitor

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

DESCRIPTION
       iptraf 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  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 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

       -f     clears all locks and counters, causing this instance of IPTraf to think  it's  the  first  one  running.
              This should only be used to recover from an abnormal termination or system crash.

       -u     allow  use  of unsupported interfaces as ethernet devices.  This is needed if you changed the name of an
              interface (ex: ip link set eth0 name foo0)

       -q     no longer needed, maintained only for compatibility.

       -h     shows a command summary

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


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