There is a simple bit of information that has finally penetrated the fog of insanity that surrounds computers and related equipment that information is this:
When using the sudo command under Linux [don't know about other systems, yet] it is the case that users who are listed in the /etc/sudoers file actually use their own account password to execute the sudo command, not [as some of use might have once thought] the root account password as is used when accessing the root account with the su command.
This information has now been shown to be true under systems that include, but are not limited to:
- KNOPPIX (with passwords and user accounts enabled
- Debian
- CentOS
