iptraf - Interactive Colorful IP LAN Monitor
iptraf { [ -f ] [ -q ] [ -u ] [ { -i iface | -g | -d iface | -s iface
| -z iface | -l iface } [ -t timeout ] [ -B [ -L logfile ] ] ] | [ -h
] }
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.
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
SIGUSR1 - rotates log files while program is running
SIGUSR2 - terminates an IPTraf process running in the background.
