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.
