CompTIA Linux +

My question is during the

CompTIA Linux+ (XK0-004) (In Production)

Class Don stated that when you sudo you enter the root password, I thought that when you sudo'd you entered your password and the authentication was based on the fact if you were in the sudoers file or not.
To use sudo you do not have to know the root password. In /etc/sudoers you would have to enter
Defaults rootpw in order for sudo to ask for the root password, this is not the default.

sudo <command> or sudo -i ask for your password not the root password.

if you su - then you have to enter the root password because you are starting a root shell.

Not trying to nit pick you just wanted to know the correct answer. Am I missing something.

Tim,

Thanks for writing in. You are absolutely correct and I mispoke in the episode. su by itself would require you to enter the root user's password, but sudo requires the user's password (assuming they were in the /etc/sudoers file) as you described. I'll have to see if I can correct that in the episode, or re-film it as that is a pretty big mistake.

Thanks again,

Don
