I'm trying to find out how much bandwidth is being
consumed by a set of clients in a local network (we
are crunching numbers and before to jumt to a Gigabit
Ethernet we need to know if our current config is
I managed to measure the bandwith between the client
and the server using iperf
to see some traffic using ethereal
but the info was not very helpfull (because ethereal

[root@linux0101 src]# tcpdump -nn -i eth0 -s 9999
src host 10.1.20.102 -w sniff2.log
Then i'm processing the data with tcptrace as
[root@josevnz devtest]# tcptrace -l -r -W
I'm sending like 9MB of data per transaction, but

headers data not the whole conversation size.
Now the questions:
1) There is a way to tell how much data was

2) How can i know the bandidth taken during a
period of time for all the clients conecting to the
