My setup is as follows: /etc/fstab does not have any reference to /dev/fd0 in the /usr/local/etc/sudoers file I have the following: # User privilege specification rootALL=(ALL) ALL aj ALL=/sbin/umount,/sbin/mount_msdosfs # end of sudoers file I have a directory with file permission 755 aj:aj /usr/home/aj/floppy ( make sure all your users have a directory call floppy with the correct file permission ) I use a small script owned by root but may be executed by all inside this script is a small message tell you it will be mounting a floppy and it must not be copy-protected next is the following line: sudo mount_msdosfs /dev/fd0 ~/floppy Now I use fluxbox...but this can be adapted to KDE withing the fluxbox menu I added the following: aterm -fg white -bg black -e name_of_script.sh ( note: I am using aterm not xterm...but should work xterm -e name_of_script.sh ) make another script to unmount with the following command sudo umount /dev/fd0 Have fun with FreeBSD... -- FreeBSD 6.0 i386 GENERIC ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

It's hard to sell an alternative, when that alternative barfs on a simple thing like Floppy-Use. The "big" stuff is in place already; M$ cpmpatibilitynin WP, Spread-sheets, mail... etc. is already far better than M$. It is the small crap, liike Floppy drive use, which makes the "conversion" a problem! The open-source community have to get their act together, and realize that main-stream users will gladly switch to FreeBsd/Linux when and ONLY when all the basics are working. For a geek, these "problems" are trivial; for a WindowZ idiot, these thjings are what kills a sale, and maintains Wind0WZ dominance in user-space. Bob pgpeCKO0kLCE8.pgp Description: PGP signature

Mount Point permissions
Hi All: This is week 3 on a new freebsd 6.1 install. I LOVE it! I am having a silly problem using my floppy drive. I can successfully fdformat a new floppy, I can newfs it, I can mount it OK what I can not do is write to it! My fstab line is: /dev/fd0 /usr/home/bob/floppy ufs rw,noauto,user 0 0 After a format, lable, and newfs, I can: "mount -t ufs /dev/fd0 /home/bob/floppy" ok. The permissions on mount-point /home/bob/floppy are 770 with bob:bob After the mount operation I see: ls -al floppy drwxr-xr-x 3 root wheel 512 Aug 7 11:22 . drwxr-xr-x 60 bob bob 4096 Aug 7 11:03 .. drwxrwxr-x 2 root operator 512 Aug 7 11:22 .snap And of course, bob can only read, but not write. $ touch floppy/test touch: floppy/test: Permission denied How can I correct the post-mount permissions?
