That depends on how the administrator has configured sudo; my openSUSE laptop asks for root's password when my user runs sudo. 2. That is an advantage, not a disadvantage in many environments; the more a password is shared the harder it is to protect and change. 'ALL=(ALL) ALL' is differently secure than have a 'su' binary around, but it is not more or less secure. -- Boyd Stephen Smith Jr. ,= ,-_-. =. email@example.com ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
