Correct. Tethereal supports "-D", to list interfaces in a numbered list, and supports using the number from that list in the "-i" option; Ethereal doesn't, so you have to specify an interface name, not an interface number. If somebody wants that, they should copy the code to support numerical arguments to "-i",, *AND* the code for the "-D" option, from Tethereal to Ethereal.
