You are probably refering to `tethereal`. I am talking about `ethereal` - the GUI. They are two different binaries. The first sentence of the ethereal man page says: "Ethereal is a GUI network protocol analyzer." At any rate, my point in suggesting ethereal was to offer up an alternative to the text based tcpdump, in the hope that it might be easier to analyze the data, not simply to offer up another text based utility. In a broad sense you are correct in that tethereal is installed along with ethereal, in a technical sense you are wrong.
