editing /etc/fstab--for rw permissions for all users


Hi,

I am using Fedora Core 1.

My /etc/fstab file read as :
Code:
LABEL=/                 /                       ext3    defaults        1 1
none                    /dev/pts                devpts  gid=5,mode=620  0 0
none                    /proc                   proc    defaults        0 0
none                    /dev/shm                tmpfs   defaults        0 0
/dev/hda7               swap                    swap    defaults        0 0
/dev/cdrom              /mnt/cdrom              udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom1             /mnt/cdrom1             udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0                /mnt/floppy             auto    noauto,owner,kudzu 0 0
/dev/hda1               /win1                   vfat
/dev/hda5               /win2                   vfat
And i didn't have write permissions to the two vfat drives as a normal user.So i googled for a while and edited my fstab as :
Code:
LABEL=/                 /                       ext3    defaults        1 1
none                    /dev/pts                devpts  gid=5,mode=620  0 0
none                    /proc                   proc    defaults        0 0
none                    /dev/shm                tmpfs   defaults        0 0
/dev/hda7               swap                    swap    defaults        0 0
/dev/cdrom              /mnt/cdrom              udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom1             /mnt/cdrom1             udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0                /mnt/floppy             auto    noauto,owner,kudzu 0 0
/dev/hda1               /win1                   vfat    user,exec 0 0
/dev/hda5               /win2                   vfat    user,exec 0 0
The problem is that i still don't have write permissions to those two vfat drives as a normal user (I know I am wrong somewhere but don't know where please point out)

Also now I have two icons named win1 and win2 on my desktop whereas i didn't have them with the previous fstab.
So, what i want now is to have write and execute permissions for win1 and win2 for all users and also i don't want those two icons to be messing up with my desktop

Please somebody help

Thanx in anticipation

add umask=000 to the options part of the VFAT drives.
The umask is the value of read/write/execute permissions that are NOT present. (i.e. if 777 is read+write+execute then the umask is 000).

This means that all files on those drives will be read/write and executable for everyone.

If you're wondering, the user flag just means that a regular user can mount the drive. If they should unmount as well then use 'users' instead.

Code:
LABEL=/                 /                       ext3        defaults                  1 1
none                    /dev/pts                devpts      gid=5,mode=620            0 0
none                    /proc                   proc        defaults                  0 0
none                    /dev/shm                tmpfs       defaults                  0 0
/dev/hda7               swap                    swap        defaults                  0 0

Hi,

Thanx for the help

I now have an interesting situation. My fstab file now looks like :
Code:
LABEL=/                 /                       ext3    defaults        1 1
none                    /dev/pts                devpts  gid=5,mode=620  0 0
none                    /proc                   proc    defaults        0 0
none                    /dev/shm                tmpfs   defaults        0 0
/dev/hda7               swap                    swap    defaults        0 0
/dev/cdrom              /mnt/cdrom              udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom1             /mnt/cdrom1             udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0                /mnt/floppy             auto    noauto,owner,kudzu 0 0
/dev/hda1               /win1                   vfat    exec,umask=000  0 0
/dev/hda5               /win2                   vfat    exec,umask=000  0 0
I have write permissions to /win2 for all users but for /win1 the case is different :
For /win1 i have write permissions (as a normal user) only in the first level in the directory tree or in the lowest level and not anywhere else :
i.e.

Code:
[koodoo@localhost koodoo]$ cd /win1
[koodoo@localhost win1]$ ls
Flash Fun  Movies  Songs  tc  tt6  WALLPAPERS
[koodoo@localhost win1]$
i.e. as a normal user :
I can write in /win1/
but not in /win1/Flash\ Fun or /win1/Movies or /win1/Songs .......................

also
Code:
[koodoo@localhost win1]$ ls
Flash Fun  Movies  Songs  tc  tt6  WALLPAPERS
[koodoo@localhost win1]$ cd Movies/
[koodoo@localhost Movies]$ ls
axn  Moon  tomnjerry
[koodoo@localhost Movies]$ cd axn/
[koodoo@localhost axn]$ls
first.mpeg last.mpeg

i can write in /win1/Movies/axn/

The system also appears to run remarkably slower

Any ideas ??

Also for more info fdisk -l gives :
Code:
[root@localhost root]# fdisk -l
 
Disk /dev/hda: 40.0 GB, 40057224704 bytes
255 heads, 63 sectors/track, 4870 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
 
   Device Boot    Start       End    Blocks   Id  System
/dev/hda1   *         1      2435  19559106    c  Win95 FAT32 (LBA)
/dev/hda2          2436      4870  19559137+   f  Win95 Ext'd (LBA)
/dev/hda5          2436      3653   9783553+   b  Win95 FAT32
/dev/hda6          3654      4804   9245376   83  Linux
/dev/hda7          4805      4870    530113+  82  Linux swap
Thanx again in anticipation

Hi,

Thanx guys I've resolved the problem.I just logged in as root and checked permissions for those files I wasn't able to write to as a normal user. As expected they were 555. So I simply changed them to 777 and now i have all the permissions as a normal user.

I not very clear about file permissions and masks
So sorry if I had done something stupid and kept u guys busy

Also I am now trying to learn more about file permissions and masks. Will try googling for it.
If anyone has a link to a good HOWTO on this please pass me the link

Thanx again you've been a great help.
