Hi all
Regarding the discussion on the saftey if one can enter LINUX by switching into single user mode at the boot prompt one solution that I can think of is to comment the line specifying the single user mode in the /etc/inittab file [ l1:1:wait:/etc/rc.d/rc 1 ]. Then the system will boot but the system can't be started correctely in the single user mode not only @ the boot prompt but even otherwise. Only the magic buttons CTRL + ALT + DEL works if not diabled.
Inorder to switch into the Single user mode then one with the rootly powers has to uncomment the line and then ask the init process to re-examine the /etc/inittab file once again by typing "init q". Then one can use the Single user mode.
Long live LINUX abhilash

Morning Kumar,
In such a situation there isn't much that one can do anyways. If physical access to the appropriate hardware in question can't be secure intrusion will always be a possibility.
What is someone walked in with one of the numerous bootcd's(Knoppix) and booted through it edited your /etc/passwd file and then booted normally the machine so as to gain root access to your priveleged data????.
As we say in our mothertongue...."If someone has made up his/her mind to rob....so be it, they will always get around to figuring a way out".
