NAME
       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  net-
       work  statistics including TCP info, UDP counts, ICMP and OSPF informa-
       tion, 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 inter-
	      face, 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 min-
	      utes.   This  option  is used only with one of the above parame-
	      ters.

       -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 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 running.  This should only be used
	      to recover from an abnormal termination or system crash.

       -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
