determine throughput from LAN to Internet, Durchsatz vom LAN ins Internet berechnen

Hi,

Does anyone have a program (or a link to a program) which determines
(under LINUX) how much a single computer in a network
downloads/uploads to/from the intenet?
In particular:
I have a linux-router connected to the internet (ppp0) and also
connected to a local LAN(ethX). Now I want to know, which of the Nodes
(connected to the internal LAN) consume how much throughput (in MB or
KB) to the Internet (extern WAN). Upload and download. Until now all
is done via 'iptables', working (masquerading).

THX for any help.

Hallo,

Kennt jemand ein Programm (oder den Link zu einem Programm) welches
unter LINUX feststellt, welcher lokale Rechner wie viel vom Internet
ladet/uplodaet?
Genau gesagt:
Ich habe einen LUNUX-router, welcher zum Internet (ppp0) als auch zum
internen LAN (eht0) verbunden ist. Jetzt möchte ich wissen, wie viel
jeder einzelne Rechner im LAN vom Internet ladet bzw. wie viel jeder
einzelne Rechner ins Internet uploadet. Bis jetz funktioniert alles
über die IPTABLES und es funktioniert (MASQUERADING).

Danke für jede Hilfe.


Cheers, Kuge

www.ntop.org - run it in webmode, point your browser to the
built-in www server, have fun.

I use ntop already and accordingly it does not show the informations i
need. It displays the throughput to the server AND to the internet if
i run it with the two arguments of the networkcards connected to LAN
and internet.
What i want to now is the amount of traffic ONLY from network to
internet and the other way round. NOT including the amount of traffic
from network to server.

Unsure what you really want, anyway you are aware that ntop is
highly configurable (man ntop)? Another option is mrtg albeit it
requires a lot more work to setup for your needs.

following scenario:

+---------+ +---O
+-------+ppp0 eth0| LINUX |eth1 | LAN
INTERNET O---+ DSL +----------+ ROUTER/ +-------+---O
| MODEM | | GATEWAY | | BOXES
+-------+ | FILESVR | +---O
+---------+

What i want to monitor is the traffic between INTERNET and LAN-BOXES.
The LAN-BOXES also have traffic from and to the LINUX
ROUTER/GATEWAY/FILESERVER. This traffic i DO NOT want to monitor. But
i can not configure ntop to monitor only the traffic from/to internet.
It additionaly monitors traffic inside LAN.

[...]

OK. Now I've just discovered that in ntop (produced web-site) under
'IP summary' there is the option 'Local >> Remote' which exactly
displays, what I need. But there is too much other information.

Furthermore I need
- something like a monthly report-file
- reset all monitored traffic on the first day of every month
- keeping the monitor-information during restart of the LINUX-Box
.... are there any command-line options which provide this things?
Maybe someone knows this already. I will also study the MAN-page.

THX
for any help.

Have you considered using MRTG package?

Glad you worked it out.

Great, as already mentioned and someone else added the URL, mrtg,
better use rrdtool (www.rrdtool.org) aka mrtg3, can do all this
and more. Again it requires a lot or only some work depending on
your experience, most initial setup. Perhaps you could try
"Cacti", found at the above URL (RRD World), this might be what
you want?

Good luck
