Hi all!

I wanted to give all users read access to my Windoze 98 partition (Yes, I
still need to have that damn W... installed (*sigh*) ), but I ran into
very strange problem. The permissions on the /mnt/windows are as default
rwxr--r--, so only root could change to that directory & read its
contents. I tried to allow all users the same, but see what happened:

8<---

<root> /mnt# ls -l | grep windows
drwxr--r-- 18 root root 4096 Jan 1 1970 windows
<root> /mnt# chmod -v a+x windows
mode of `windows' changed to 0755 (rwxr-xr-x)
<root> /mnt# ls -l | grep windows
drwxr--r-- 18 root root 4096 Jan 1 1970 windows
<root> /mnt#

8<---

What mechanism keeps me from changing the permissions of /mnt/windows (as
root!), or changes it back when I turn my back? And more importantly, HOW
CAN I DISABLE IT...! Very strange

By the way, I'm using Slackware 9.1

Try mounting it with 'user' and 'umask=077', eg. in fstab:

/dev/hdb1 /win vfat rw,user,umask=077,conv=a 0 0

The fat filesystem has no concept of permissions. You need to set a umask
for the whole filesystem when mounting or in fstab. I have in my fstab
somehting like nouid,nogid,noexec,rw,users,umask=000.

Thanks for the help! I replaced the 'defaults' in fstab with
'rw,umask=022', that did the trick... I KNEW that fat filesystem haven't
got any permissions, I just thought that the directory /mnt/windows still
belonged to the *nix filesystem, and all after that to the *doze.
Obviously I was wrong... Thanks again

I'll give you the same advice as I got when I asked this question:
man mount (look at the fat filesystem options).

Try: mount -t vfat -o uid=username /dev/hda1 /mnt/windows
