Traffic Monitor

[Carlos Alarcon]

If you want graphs too.. you can try NTOP and BANDWITDH, these programs
gives results on web pages including stats and nice graphs, bandwith gives
you a top 10 users with most traficc on you network, i use them on my
network with good results, but the little problems is that these progs are
hungry eaters of ram.
