want to config my system such way that if anyone tries to change my root password
mail the new password to system admin.
well root is the admin. most of the time if you are root then how could the system email you a new password. to admin. do you understand what I am saying.
or are you trying to say if some one mess with your password you want the system to lock it out and issue a new password that only an root admin can get.
why even have a password then. most system just lock that user out till it is restarted. But since your root. who knows who admin is I guess root. or did you as root set up another user with admin and root privileges.
Enough you are not root on the system the admin is and you will have to ask your admin to set up a system that generates passwords. find a good linux script writer and send him to your admin so so your admin that has root privileges of your computer can allow this.
that why admin support gets all the big dollars.
Here at the U of I all staff people that work with personal data get a new password given to them every 3 month or less.
