.SH DESCRIPTION
.B 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.
.PP
If the
.B 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.
.SH OPTIONS
These options can also be supplied to the command:
.TP
.BI "\-i " iface
immediately start the IP traffic monitor on the specified interface, or
all interfaces if "\-i all" is specified
.TP
.B "\-g"
immediately start the general interface statistics
.TP
.BI "\-d " iface
allows you to immediately start the detailed on the indicated interface (iface)
.TP
.BI "\-s " iface
allows you to immediately monitor TCP and UDP traffic on the specified interface (iface)
.TP
.BI "\-z " iface
shows packet counts by size on the specified interface
.TP
.BI "\-l " iface
start the LAN station monitor on the specified interface, or all LAN
interfaces if "\-l all" is specified
.TP
.BI "\-t " timeout
tells IPTraf-ng to run the specified facility for only
.I timeout
minutes. This option is used only with one of the above parameters.
.TP
.B "\-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.
.TP
.B "\-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
.B /var/log/iptraf-ng
.TP
.B "\-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.
.TP
.B "\-h"
shows a command summary
.SH SIGNALS
SIGUSR1 - rotates log files while program is running
SIGUSR2 - terminates an IPTraf-ng process running in the background.
.SH FILES
/var/log/iptraf-ng/*.log - log file
/var/lib/iptraf-ng/* - important IPTraf-ng data files
