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  informa-
       tion, 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
