I have mounted an xp ntfs share drive on my raspberri pi with the command sudo mount -t cifs -o guest //192.168.1.103/share1 /mnt/mtmy
The only way that I can edit and save files in this directory from raspberri pi is to use the sudo command. eg. sudo leafpad etc. Unless I precede with sudo I have a permissions problems and cannot save my changes.
I have tried sudo chmod 666 -r * from the mtmy location and I get "permission denied" response as it recurses. I have also tried sudo chown and got a similar response.
I can access this windows share from other windows machines with no permissions problems so I don't think the problem is related to windows sharing. However, it appears that not even using sudo can make the permissions changes in rpi to grant permission to other users.
