.SH DESCRIPTION
.B ipfm
is a bandwidth analysis tool. It counts how much data was send and
received by specified hosts through an Internet link.
.B ipfm
is based on the libpcap (ftp://ftp.ee.lbl.gov/libpcap-0.4.tar.Z, see
http://www.tcpdump.org/ for newer versions) and should be portable.
.B
ipfm is developed under Linux libc6 (Debian sid).
It was reported to work under Linux libc5 (slackware) and libc6 (RedHat,
SuSE), FreeBSD, OpenBSD, IRIX, Solaris, HP-UX and AIX.
As we can't test new versions under these OSes, there might be problems. Please
report them at ipfm@via.ecp.fr.
.SH OPTIONS
Note that depending on the OS, long options may no be supported.
.IP "-c config-file, --config config-file"
.I config-file
specifies an alternate configuration file to use. By default,
.IR __CONFIGURATION_FILE
is used.
.IP "-n, --nodaemon"
does not run as a daemon
.IP "-h, --help"
displays an help message on standard output and exit
.IP "-p pid-file, --pid pid-file"
.I pid-file
specifies an alternate pid file to use. By default,
.IR __PIDFILE
is used.
.SH SIGNALS
.B ipfm
reacts to certain signals.
.TP
.I SigHUP
This causes
.B ipfm
to dump (and clear) its data tables in the log file (see
.BR ipfm.conf (8)
), close pcap descriptor, reload configuration file and restart.
.TP
.I SigTERM
This causes
.B ipfm
to dump (and clear) its data tables in the log file (see
.BR ipfm.conf (8)
) and exit.
.TP
.I SigKILL
This causes
.B ipfm
to exit.
.TP
.I SigINT (ctrl-c)
This causes
.B ipfm
to exit after having dumped and cleared its buffers.
.TP
.I SigUSR1
This causes
.B ipfm
to dump its data tables in the log file without exiting or clearing them.
