Created some simple IP based Ethereal Coloring Rules (previously known as Ethereal Color Filters I think) for colorizing the Ethereal packet display. The file was saved in Ethereal 10.6 for Windows don't know if that will cause problems on Unix or other versions, but have fun with them. I really wish I could find a more complete set of color filters, but these at least show SYN, RST, FIN packets and then several of the analysis type packets that Ethereal can automark like Fast Retransmissions and the like.
You just need to save the following link, then IMPORT into Ethereal's Color Filter menu.
