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 [email protected]

OPTIONS

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

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

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

SIGNALS

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.
