Description amit2070 2000-06-07 19:14:02 UTC
My name is Amit 
Since, it is not posible for me to be present at my clients place 
throughout the day i have given shutdown permissions to two users. there 
job involves just shuting down the server every evening. When the shutdown 
now command is issued linux switches to single user mode and automaticaly 
logs in as root without any authentication. this creates a serious 
security hazard.
I would like to know how can i avoid this or if its a bug is it rectified 
in the letter version
I would apreciate any guidence you could provide in this regard 

Thank You,

Switching to single-user mode is normal for runlevel 1;
we don't require a root password because those with console
access can get this in many other ways. Some of the things
you can do if you're willing:

- password protect your lilo.conf
- add 'sulogin' to the end of /etc/rc.d/init.d/single
other things of that sort...
