# ipfm(8)

IP Flow Meter

## NAME

ipfm - IP Flow Meter

## SYNOPSIS

**ipfm** \[-c *config-file* \]\[--config *config-file* \] \[-h\]\[--help\] \[-n\]\[--nodaemon\] \[-p *pid-file* \]\[--pid *pid-file* \]

## DESCRIPTION

**ipfm** is a bandwidth analysis tool. It counts how much data was send and received by specified hosts through an Internet link.

**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.

**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.

## OPTIONS

Note that depending on the OS, long options may no be supported.

- \-c config-file, --config config-file

  *config-file* specifies an alternate configuration file to use. By default, */etc/ipfm.conf* is used.

- \-n, --nodaemon

  does not run as a daemon

- \-h, --help

  displays an help message on standard output and exit

- \-p pid-file, --pid pid-file

  *pid-file* specifies an alternate pid file to use. By default, */var/run/ipfm.pid* is used.

## SIGNALS

**ipfm** reacts to certain signals.

- *SigHUP*

  This causes **ipfm** to dump (and clear) its data tables in the log file (see **ipfm.conf**(8) ), close pcap descriptor, reload configuration file and restart.

- *SigTERM*

  This causes **ipfm** to dump (and clear) its data tables in the log file (see **ipfm.conf**(8) ) and exit.

- *SigKILL*

  This causes **ipfm** to exit.

- *SigINT (ctrl-c)*

  This causes **ipfm** to exit after having dumped and cleared its buffers.

- *SigUSR1*

  This causes **ipfm** to dump its data tables in the log file without exiting or clearing them.
