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 in-
cluding TCP info, UDP counts, ICMP and OSPF information, 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 inter-
faces 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 parame-
ters 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 ser-
vice statistics, packet size breakdown), or the instance of the facility (IP traf-
fic 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 termina-
tion 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
