[SOLVED] can't chmod as root

bitpal · 2008-02-13 12:27:28

Trying to set write permission for all on directory /share and file /share/test.

Current permissions:

drwxr-xr-x 4 root root 4096 2008-02-13 13:15 /share
-rwxr-xr-x 1 root root 509 2008-02-13 13:16 /share/test

I tried (as root)

chmod 0777 /share
chmod 0777 /share/test

and

chmod a+w /share
chmod a+w /share/test

No error is returned, but the permissions don't change! Any ideas?

nfs mount ?

bitpal · 2008-02-13 13:14:53

No, it's fat32

zyghom · 2008-02-13 13:21:05

man mount ?

bitpal · 2008-02-13 13:24:59

Do you mean, is it a manual mount? No, it's mounted in fstab.

zyghom · 2008-02-13 13:58:22

I mean: check options in /etc/fstab according to what you want to get
specially for fat there are different options

bitpal · 2008-02-13 14:02:24

This is my fstab:

none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0


/dev/cdrom /mnt/cdrom   iso9660   ro,user,noauto,unhide   0      0
/dev/cdrom1 /mnt/cdrom1   iso9660   ro,user,noauto,unhide   0      0
/dev/dvd /mnt/dvd   udf   ro,user,noauto,unhide   0      0
/dev/fd0 /mnt/fd0   vfat   user,noauto   0      0
/dev/sdb5 /share vfat defaults 0 1
/dev/sdb6 swap swap defaults 0 0
/dev/sdb7 /boot ext2 defaults 0 1
/dev/sdb8 / ext3 defaults 0 1
/dev/sdb9 /home ext3 defaults 0 1

What could be wrong with /share here?

I am assuming that you are trying to make this folder and the mount readable and writable to non-root users.

Unmount the filesystem as root, then set the group to /share to disk. Then make sure that the users are part of the disk group. Then set the permissions to 775.

Once you have done this, edit your fstab line so it appears to be something like this:

/dev/sdb5 /share vfat auto,group,exec,nosuid 0 0

This should work fine.

bitpal · 2008-02-13 15:07:07

I did:

umount /share
chgrp -R disk /share

then set the line in fstab as you said, and rebooted.

The permissions are still read-only for others, and chmod has no effect.

Maybe I should add that this is a samba share - does that make any difference? I thought root has full rights to chmod no matter what?

OK, I solved it. I stopped samba and chmod works.

Makes sense: how can the server change access rights to a share while other machines are reading/writing to it?

Thanks sic and zyghom for your input; I was about to give up on this (letting the windows box write to the share), if you hadn't gotten me to think of all the possibilities!

did I mention nfs ? did I mean "shared so untouchable" ? :-)

Sorry, I didn't even know what you meant by nfs (new files system? nt? ntfs?), so I couldn't place your question...

zyghom · 2008-02-13 16:25:21

nfs - network file system ;-)
but you are right: I should have been clear by stating: "shared resource cannot be changed"

bitpal · 2008-02-13 16:34:03

Thanks for clearing that up.

Can I just continue this with my ACTUAL samba problem? I've been struggling with this for 3 days, trying to get write access to the share from my xp laptop. I can browse the share folder from xp, but I can't edit/change/add files.

Can you help me with this? I'll post my smb.conf if you're willing...

Or should I start a new thread?

I did some homework on this, so I started a new thread:
