Hi again,

Ethereal is a network monitor which performs passive analysis. What I
need is something which include mechanisms to measure the maximum
throughput (so it have to inject packets on the network and ethereal
doesn't).
I've also used mgen or iperf, but yet are necessary supplementary
tools for an exhaustive analysis.
