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 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
/var/lib/iptraf/* - important IPTraf data files
