I simply can't work out how to get read/write permission to all member of the 'common' group. What I want is: hda1 ro to group=common (WinXP) hda6 rw to group=common (SharedFiles)
From what I can tell root currently has ownership and group is also root, no-one else can write.
In FC2 when i go into /mnt/SharedFiles > Properties > Permissions and try to change anything i get the message
"The group could not be changed - You do not have the permissions necessary to change the group of 'SharedFiles' ".
Seems absurd - as I'm logged in as root, and own the partition/directory.
In XP(SP2) if i look at 'E:\ > Properties > Sharing' both the 'Share this folder on a network' (i have a local network) and 'Allow network users to change my files' are ticked.
OK: first misapprehension. "Share this folder on a network" means "Use Windows XP's networking stack to make this available to other computers on the network. When you're running Fedora, you're not running XP (on that machine), so it's not relevant.
Secondly, your SharedFiles partition is formatted as FAT32. This is good: Linux can write to it. But there is inherently no concept of file ownership on FAT32: Windows pretends there is, sometimes, but there's nothing for root or anyone to change on the disk.
Your WinXP partition is NTFS. There's very limited support for writing it, and it doesn't come with Fedora. You either have to compile your own kernel, or install appropriate RPMS: see http://linux-ntfs.sourceforge.net/rpm/fedora3.html
NTFS *does* have concepts of users and ownership, but it doesn't map easily to Linux users. So far, the developers haven't tried.
So how do you change user rights on mounted filesystems?
My fstab file included these lines: /dev/hda11 /mnt/data vfat defaults,gid=501,dmask=2,fmask=113 0 0 /dev/hda5 /mnt/winnt ntfs noauto,gid=501,dmask=2,fmask=113 0 0
501 is the group with write access to the drives: in your case, do grep common /etc/group and take the number in the third field.
Hope this helps,
James.
OK, thanks. Works great now. One less thing to get to grips with...
those lines now read:
/dev/hda1 /mnt/WinXP ntfs auto,defaults,gid=501,dmask=2,fmask=113 0 0 /dev/hda6 /mnt/SharedFiles vfat auto,defaults,gid=501,dmask=2,fmask=113 0 0
See any problems with that? I just need to get the correct kernel so i can read ntfs again.
