This is confusing the hell out of me: I want to allow a user, AND ONLY THAT USER, to mount CD's and floppys. We'll call him 'bob'. I added 'bob' to the groups floppy and cdrom. adduser bob floppy adduser bob cdrom
my mount points are: /dev/fd0 /mnt/fd0 vfat defaults,user,noauto 0 0 /dev/fd1 /mnt/fd1 vfat defaults,user,noauto 0 0 /dev/cdrom /mnt/cdrom iso9660 defaults,user,noauto 0 0 /dev/cdrw /mnt/cdrw iso9660 defaults,user,noauto 0 0 /dev/mcd /mnt/mcd iso9660 defaults,user,noauto 0 0 /dev/zip /mnt/zip vfat defaults,user,noauto 0 0 and an ls -l of my /mnt directory shows: dr-xr-x--- 2 root cdrom 1024 May 18 21:51 cdrom/ dr-xr-x--- 2 root cdrom 1024 May 18 21:51 cdrw/ dr-xr-x--- 2 root floppy 1024 May 18 21:51 fd0/ dr-xr-x--- 2 root floppy 1024 May 18 21:51 fd1/ dr-xr-x--- 2 root cdrom 1024 Aug 16 21:07 mcd/ dr-xr-x--- 2 root floppy 1024 May 18 21:51 zip/ Now, if 'bob' mounts the cdrom, /mnt/cdrom becomes: dr-xr-xr-w 2 root root 1024 May 18 21:51 cdrom/ And now ANY user can see the contents of the CD!!! Why did the group and permissions change? How do I prevent other users from changing into that directory (/mnt/cdrom)? Thanks, Bryan
