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
