hello !

I know this is a stupid question.

I can't write anything on my /mnt/hda7 that holds a fat32 partition, where I keep my downloaded stuff.

How should I configure it so an ordinary user (not root)
is able to write data on that partition ?

I know that I must change some kind of permissions / stuff

please help !

Excalibur

Try the unmounting the partition.

chmod 777 /mnt

or

chmod 775 /mnt; chgrp users /mnt

Then remount the partition.

The first command above should open it to the everybody, unrestricted, if it is mounted read/write and not read-only. The second would make it read/write/execute by the group called "users", and read/execute by the world.

Unless /mnt/hda7 is the mount point and not /mnt, you should consider making a directory like /mnt/shared or /mnt/vfat, or something. The /mnt directory usually has other subdirs like /mnt/cdrom, /mnt/floppy, and /mnt/hd that could be used by other commands.

Sorry !

None of the suggestions worked, no succes . .

Have I forgotten something else ?

If I change owner/permission on /mnt, then all the subfolders will inherit the /mnt settings right ?

To clear it out, hda7 is my fat32 partition & this is monuted in the /mnt folder.

Excalibur

From the console prompt type

mount

It should respond with all of the mounted devices. Make sure it is mounted as "rw" for read/write like your other partitions. Also, I think you need to be sure to unmount and remount.

As for inheritance, it is a fat32 partition you stated and fat32 does not have any concept of permissions to begin with. So I would think it would inherit the permissions of the mount point when it is mounted. You can use the "ls -l" command to display the permissions of the files after it is mounted to see what is assigned. Note: That was a lowercase "L" on the command option.

Let me know the results.

Your mount point is /mnt/hda7 and it is device /dev/hda7. The permissions above would need to be done to /mnt/hda7 and the others that you desire to allow the write permissions.

/mnt/hda7 currently has read/write/exe for root, read/exe only for the group root, and read/exe only for the world. Use "chmod 777 /mnt/hda7" for example and remount the partition. Repeat as desired for the other partitions.

All of the mounts indicate "rw" for read/write.

still not working . . .

I tried umount /dev/hda7 and /mnt/hda7

then the chmod stuff . .

then mount /dev/hda7 and mnt/hda7

If it is to any help, here is the fstab file.

/dev/hdb5 swap swap defaults 0 0
/dev/hda6 / ext2 defaults 1 1
/dev/hda7 /mnt/hda7 vfat defaults 1 0
/dev/hda8 /mnt/hda8 vfat defaults 1 0
/dev/hda9 /mnt/hda9 vfat defaults 1 0
/dev/hda10 /mnt/hda10 vfat defaults 1 0
/dev/hdb6 /mnt/hdb6 vfat defaults 1 0
/dev/hdb8 /mnt/hdb8 vfat defaults 1 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro,user 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0

Excalibur

Can you write to the partition as root?

bynaar

Yes !

Excalibur

I can only recommend at this point to use the "ls -l" command and verify that the chmod command worked as expected.

OK. In the listing here the mount point /mnt/hda7 is still at 755. It has not been changed to 777. Please use "chmod 777 /mnt/hda7" as root. Perhaps you executed it as a user and not root. Then umount and mount the partition.

Thanks for trying to help !
I'm getting to tired for this . .

This probably isn't the best way, but anyway...

mount /dev/hda7 /mnt/hda7 -o id=your-login,gid=users

or have something like this for it in /etc/fstab

/dev/hda7 /mnt/hda7 vfat user,uid=your-login,gid=users 1 0

Excalibur

I think I might have figured out what is going on. Since the type of the partition is vfat, the mount command is setting the permissions and owner to the default of the user that is mounting it. In this case, root. The default umask for root is set to 022 in the /etc/profile file. Hence the permissions are set to 755 on the mount point. I would think that by adding the option to the fstab to change the umask might be as simple.

/dev/hda7 /mnt/hda7 vfat defaults,umask=000 1 0

The umask is a bit mask used to set the actual permission bits. In this case it should set them to 777 because the mask is set to all zeroes. After making the change remount the partition.

This is the type of case where I can learn as well. Because I never use vfat partitions on production machines, I have never had to deal with it before. I was only able to test it using a floppy disk, but it worked.
