If you want to grab the digital data off of an audio CD and stuff it on your hard drive, use the /usr/ports/audio/tosha port. > 2)Is it possible for a user who is not root to mount a file system? > I'd like to setup a FAT file system so that any user can mount it read > only. I don't think so. Linux has the "user" mount option to do this, but (AFAIK) FreeBSD does not. There is a little trick you can use, though, to get around this. Just make the /sbin/mount and /sbin/umount binaries setuid to root, chgrp it to a group (make a new group "mounters" for this purpose), then make these executables NOT executable by everyone else. Then, to allow a user to mount and unmount stuff, just add him/her to the "mounters" group. The permissions of the binaries should look like this: -r-s--x--- 1 root mounters 73728 Jul 22 01:13 /sbin/mount* -r-s--x--- 1 root mounters 126976 Jul 22 01:13 /sbin/umount* --- Donald Burr <dburr@pobox.com> *NEW EMAIL ADDRESS!* | PGP: Your WWW HomePage: http://DonaldBurr.base.org/ ICQ#16997506 | right to Address: P.O.
