The traces can be used to study > network dynamics, usage characteristics, and growth patterns, as well as providing > the grist for trace-driven simulations. The archive is also open to programs for > reducing raw trace data to more manageable forms, for generating synthetic traces, > and for analyzing traces. and at: http://town.hall.org/Archives/pub/ITA/html/software.html which contain some links to software and script that will reduce tcpdump output, and other stuff. You may also have a look at the Stevens book: TCP/IP Illustrated volume 1. Stevens use tcpdump as a tool for teaching tcp/ip, from a pedagogical point of view (I'm learnig), I find it usefull. Take this as suggestion only. Before using tcpdump, I was thinking that it was cumbersome, but after reading the man page and try some examples, it came alone... hope this help - -- Meir Bis Software System Ltd, Unix programmer Gary Vinson wrote: > > Hello, > > We have experienced a couple of bad ethernet cards (broadcasting like > crazy) and a bad cable or two on our LAN.
