ipfm8

Usage

Overview

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.

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

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

-h, --help

-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.
