Hi Guy
Ups, sorry. Forgot to tell it was Windows.
Ok, that sounds as a good explanation. But still, from where does it finds
the names of those interfaces.

On Windows? If so, then, whilst you may have only one *physical*
interface, for some reason, Windows may have added some "virtual"
interfaces, e.g. one for dial-up networking (perhaps even if you aren't
using, and have never used, and have never configured, dial-up
networking; as I remember, my W2K machine at work lists an NdisWan
interface even though I don't think I installed dial-up networking and
certainly didn't configure it - it's not even plugged into a modem).
I don't know whether, either on Windows OT {95, 98, ME} or Windows NT
{NT 3.x, NT 4.0, W2K a/k/a NT 5.0, WXP a/k/a NT 5.1}, there's any
equivalent to the "UP" flag on most if not all UNIX systems - or, if
there is, whether it's set on those various "virtual" or "dummy"
interfaces even if they're not in use - so I don't know if there's a way
to have Ethereal (or WinDump, for that matter) eliminate
present-but-inactive interfaces from the lists they show.
