Red Hat Bugzilla – Bug 11958
Problem with runlevel 1
Last modified: 2014-03-16 22:14:10 EDT
Hello, 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, AMIT
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...
