       iptraf - Interactive Colorful IP LAN Monitor


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


       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.


       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

       -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


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


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