Looks like the ping code (or the ping > type may be invalid for the interfaces...???).... That's just performing a connect() scan - it doesn't require any monkeying around directly with the interfaces (which pinging does). If you try one of the cleverer scans (eg, -sS) it should complain about not finding interfaces even without -P0. The reason it works as a user is because users don't have enough access to do anything that requires nmap to form packets itself (like ping does). -- Mark Brown mailto:[EMAIL PROTECTED] (Trying to avoid grumpiness) http://www.tardis.ed.ac.uk/~broonie/ EUFS http://www.eusa.ed.ac.uk/societies/filmsoc/
