 Posted: Wed Oct 20, 2004 11:49 pm Post subject: can't mount floppy as user [solved] |
 |
|
I try not to do mundain tasks as root but it gets harder by the day.
It was recently deemed a security risk to let user accounts access to CD burning.
Now it seems I cant mount or even read a floppy from a user account.
| Code: | prof@linbox ~/wine_root/InvoiceMan $ mount /mnt/floppy
mount: only root can mount /dev/fd0 on /mnt/floppy
prof@linbox ~/wine_root/InvoiceMan $ ls !$
ls /mnt/floppy
invman.exe
prof@linbox ~/wine_root/InvoiceMan $ cp !$/inv* .
cp /mnt/floppy/inv* .
cp: cannot stat `/mnt/floppy/invman.exe': Permission denied
prof@linbox ~/wine_root/InvoiceMan $ ls !:1
ls /mnt/floppy/inv*
ls: /mnt/floppy/invman.exe: Permission denied
|
however:
| Code: | 1 drwxr--r-- 2 root root 7168 Jan 1 1970 floppy
|
I hope I am just making an elementary error because otherwise this situation is getting rediculous.
If all a user account can do is ls ~ , what's the point ?
Thanks for any help. Gentree.

What does the relevant line in your /etc/fstab say? Do you have 'users' in the options part?

Thanks,
well I added that , umount then remount the floppy but it does not seems to change anything I was doing.
| Code: | prof@linbox ~/wine_root/InvoiceMan $ ls /mnt/floppy/*
ls: /mnt/floppy/invman.exe: Permission denied
|
root has no problems :
| Code: | -bash-3.00#ls !$/*
ls /mnt/floppy/*
/mnt/floppy/invman.exe
|
I take it from your reply that this is not normal , so at least some good news, now to see where I am going wrong.
Thanks again.

| I have "user" (not "users") in my fstab, and I can read/write floppies all right. |

Thanks for the replies.
I had 'user' on my cdrom lines but thought it was an error after the 'users' suggestion , dont know if its the same. Anyway all are set to 'user' now but the pb remains.
| Code: | -bash-3.00#su prof
prof@linbox /root $ ls /mnt/floppy
invman~1.exe invman~1.zip
prof@linbox /root $ ls /mnt/floppy/*
ls: /mnt/floppy/invman~1.exe: Permission denied
ls: /mnt/floppy/invman~1.zip: Permission denied

semms my user can ls the floppy but not files or directories on it.
Does that make sense to someone?
TIA

What are the access permissions on those files?

I have used both user and users. I am not sure the exact difference, but I believe that user is a little bit of a mix of owner and users. owner means that you have to be at the machine to mount. I believe user means that the device needs to be either unmounted or you need to have mounted it to change it. I think that users means that anyone can mount or unmount it.
You might want to check the permissions on the /mnt/floppy directory to see if users on the machine can access it.
You need execute permissions on directories to read the contents. (755) |

Do I really! How odd , I wont even ask why.
In any case it wont take a change. As root ...
| Code: | chmod 755 /mnt/floppy
-bash-3.00#!l
ls -ail /mnt/floppy
total 949
1 drwxr--r-- 2 root root 7168 Jan 1 1970 .
3557 drwxr-xr-x 12 root root 312 Sep 13 23:14 ..
10 -rwxr--r-- 1 root root 482304 Oct 21 10:05 invman~1.exe
11 -rwxr--r-- 1 root root 482304 Oct 22 03:26 invman~2.exe
|
from /etc/fstab :
| Code: | /dev/fd0 /mnt/floppy vfat noauto,noatime,users
|
Thanks to all...
