Ethereal has changed its name

http://www.wireshark.org/

I just discovered that the Ethereal program I have used and loved for so long now goes by the name Wireshark. I would encourage everyone to download and play with Wireshark to help understand the OSI model and network communications better. We will do a lot with this program throughout the semester.

On a related note, this is a great blog that goes through tracing network communications, has sample dumps to put in Wireshark to look at, and even talks about spyware infections.
