Hello there, folks.
The question is the following. I have a linux router box with ubuntu which routes internet for several people. There is no extra traffic shaping, so everybody can get the whole bandwidth when its free. What I would like to have is a real time traffic counter per ip, just like a program called "iptraf" but on a per-ip basis. Iptraf can only count on a per-connection basis and thus cannot display a bandwidth that a certain ip has taken (because a single ip can start several onnections).
So a console program with text interface like iptraf would be perfect - does anybody know about such a program? After some googling I came to the conclusion that such a program does not exist (which must be wrong - i think that per-ip real time traffic flow information is the first thing every router owner would like to know). Thanks in advance.

You will want to learn more about Linux routing. It has the depth that you need
but you will need to learn more about filtering classification and queues.

The Linux Advanced Routing and traffic control (lartc) is a little dated but
get you all the detail to start seeing what you want and also bandwidth control.

If you want to do this without switching distro then here is a link for tools that should
be able to be installed via apt-get.

Here is a link for a tutorial on installing and using ntop which is very close.

Also if you want to switch distros then I would recommend custom distros that are specific for routers
One of those is http://www.untangle.com/

Hi,
If you want to know "only" howmuch traffic per ip , you can use bandwidthd.
See here http://bandwidthd.sourceforge.net/
