[SOLVED] accessing root with/without password

mahmoodn · 10-30-2010, 05:06 AM

I used

Code:

sudo passwd

to change root's password. However when I run

Code:

sudo su

, I see roots prompt without any password request!. If I use

Code:

su

, then I have to enter root's password (which I set with "sudo passwd").

Is my system secure?

Yes it is (at least as far as sudo is concerned). It 'remembers' the password you entered for sudo for a while. That way, if you issue another sudo command within a certain timeframe and in the same console you wan't get asked again. You will allways have to enter the root-password if you use su.
If you open a new console-session and enter

Code:

sudo <whatever-command>

you will be asked again.
