Hi,

On the first query, I guess you want to look at the disk partition layout. If so, do (as root) :

/sbin/fdisk -l /dev/hda (first ide disk)
/sbin/fdisk -l /dev/hdb (second ide disk)
/sbin/fdisk -l /dev/sda (first scsi disk)
/sbin/fdisk -l /dev/sdb (second scsi disk)

etc.

Also look in /etc/fstab to see what filesystems are configured already.

On the ctl-alt-del - this can only be done from the system console so is not subject to great security, however you should be able to restrict it to certain users by putting their userids in the file /etc/shutdown.allow .

Hope this helps

You can define the behavior of ctl-alt-del in inittab, but this is a total limitation. As ifincham said: console only...are you teaching linux or something so users have to be at the con?
