Why did I write iam? Why do you want to use iam?

While looking for a traffic reporting tool, I didn't find something that meets my requirements. So I started to write iam, which:

is free software
works with Linux 2.4 iptables
is written in a readable language (i.e. not perl, awk or shell script)
is secure (i.e. only be root where you need to be root)
doesn't depend on a specific web server or database server
can generate reports for routers or servers
can generate reports in plain text or HTML format
can calculate costs for traffic (currently only price per MB, but bulk discounts should be included soon)

You don't want to use iam?

This is a list of free software alternatives to iam:

IP Accounter:
http://sourceforge.net/projects/ipac-ng/

IP-Accounting Grapher:

BW ACCT:

Requirements

Python 1.5.2 - http://www.python.org/
iptables 1.2 - http://netfilter.samba.org/

cron must be installed to automatically dump iptables output to a file, cron is also convenient for generating iam reports on regular intervals.

You only need root access to install the iptables script and to dump it's output. but iam doesn't need to be run by a privileged user.

iam_report currently needs a GNU version of date for the --date option.
