iptraf - Interactive Colorful IP LAN Monitor


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


   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

   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.


   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

   -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


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