iptraf - Interactive Colorful IP LAN Monitor


SYNOPSIS

       iptraf  {  [ -f ] [ -q ] [ { -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 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 traf­
              fic on the specified interface (iface)

       -z iface
              shows packet counts by size on the specified inter­
              face

       -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 stan­
              dard input, and forks the program  into  the  back­
              ground.   Can be used only with one of the facility

              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 moni­
              tor, LAN station monitor).  If a path is not speci­
              fied, 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 run­
              ning.   This should only be used to recover from an
              abnormal termination or crash.

       -q     no longer needed, maintained only  for  compatibil­
              ity.

       -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/local/iptraf/* - important IPTraf data files
