I have NEVER set up a root password, however I have just run the sudo cat /etc/shadow command and it shows:
and so on
I have read that the 1st number is the number of days after Jan 1 1970 that the password was changed. Most of the others show 15994 which equates to 16/10/13 however root shows 16066 which would equate to 27/12/2013. Does this mean that there was a root password set/changed on this date, as I never set a root password? I am therefore concerned about the security of my system.
Any guidance would be very much appreciated. I realise the ! signifies there is no password at present.
