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].
