iptraf - Interactive Colorful IP LAN Monitor
iptraf-ng { [ -f ] [ { -i iface | -g | -d iface | -s iface | -z
iface | -l iface } [ -t timeout ] [ -B [ -L logfile ] ] ] | [ -h ]
}
iptraf-ng 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-ng 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-ng 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-ng
-f clears all locks and counters, causing this instance of
IPTraf-ng to think it's the first one running. This should
only be used to recover from an abnormal termination or
system crash.
-h shows a command summary
SIGUSR1 - rotates log files while program is running
SIGUSR2 - terminates an IPTraf-ng process running in the
background.
