I've been tackling my to-do list for my wireless router. I needed to check what packets were actually hitting one of my computers on the LAN side. Out of habit, I went to download Ethereal from http://www.ethereal.com.
I didn't make the above URL a clickable link for a reason. It turns out that development of Ethereal has ceased, and picked up as Wireshark due to trademark reasons. This actually happened quite a while back, but slipped past my radar, so hopefully this will be news to someone else, too. Of course, it doesn't help that nothing is mentioned about this on the Ethereal page, unless you go to the wiki link. (See Wireshark's Wikipedia page for some additional details.)
