Unfortunately I do not recall the application name and I'm not able to find it again, although I've reviewed the Ports collection from year 2005 which I have on 3 DVDs. I do not remember if the application captured data from the network interface by itself, or used tcpdump output, that actually doesn't matter. What matters is that this app draw a picture of the selected IP packet's header, similar to the one in RFC791 at page 11, chapter "3.1. Internet Header Format". The picture drawn was minimalistic and in colors (green, yellow), and it showed the field values from the actual capture. I've ran it under TWM, and it looked close to that one, but showing captured values instead of (or along with) field names - Appreciate if anybody remembers that application by a chance and could tell its name. thank you 3des
