What are the permissions on the /dev device entries (/dev/cdrom, etc)? That's usually a clue - if they are set incorrectly, then you won't be able to access them as a user. /dev/cdrom should be permissions 440 (i.e., as root, do chmod 440 /dev/ cdrom) - because the owner should be able to access the cdrom as well as the group (more on that later) but 'outsiders' i.e., the world, if you have any remote users - shouldn't have access to the 'raw' device. Now they *can* have access to the directory where the cdrom is mounted, and IIRC that doesn't necessarily mean they need read access to the device. Lots of setups do things differently, and I may not be quoting the "party line" here - but it's your system :). My rationale is based on having users that can have access to the device (other than root) such as a "disk" or "audio" group. That is why I set the group read permissions on. If you yourself as a user are added to that group, then you get to use the device. What complicates matters is that (I think) somehow the permissions are being reset - and further complications arise if you use "auto-mounting" deamons and the like. Personally, I just like the idea of mounting a new CD as root, and then letting the user use the mount point, rather than having direct access to the device. > I need the floppy drive....(No network yet, coming soon) > So smarty that I am I pull out the books.

I think you're on the right track. root:x:0:root bin:x:1:root,bin,daemon daemon:x:2:root,bin,daemon,ldap (snips) (here I only have one user, i.e., me, but this should be enough cdrom:x:22:dfox usb:x:43:dfox cdwriter:x:80:dfox audio:x:81:dfox users:x:100:dfox etc. > Doesn't help a bit.

Remember it's not simply the permissions on the device - a user needs to be able to see the files, for instance in /mnt/cdrom. If that's not also accessible by the user, it won't make a difference if he's in the cdrom or the floppy group. > -Curt
