Note: linux kernel 2.2 used ipchains, 2.4 uses iptables.
HOW DOES IT WORK?

ipac consists of two scripts (shell and perl) and one C program:

- - ipacsum summarizes
the data from a set of files
and, optionally
,
- replaces these files by one
. It displays the values as a simple
- table containing
the sums, as png graph pictures
or as ascii graph
- pictures
.
+If you're running debian,
the config file format is slightly different to newer versions. You don't have ipac~in/out/fwin etc, you just have 'in'
and 'out'
, and both in and out get called on the forward chain.
+
+If you're running ipac on a machine that is a gateway between two networks
, you will find that your totals are largely irrelevant because if I download 2Mb of stuff, I will get 2Mb in on the external interface and then 2Mb out on the internal interface.
+
+The easiest way around this is to simply monitor your internal interface.
You really don't care about internal traffic because it's all free
.
+
+Edit /etc/ipac-ng/ipac.conf and replace
the +'s with 'eth1'
or 'ppp0' etc
.
