Raspberry Pi NTFS SAMBA SHARE Permission denied Windows 7

Question

I'm running a little RaspberryPi machine that I wanted to turn into a low power network share that is completely unprotected on my home network, the aim is for it to be a universal network dump and media share.

I have got USB drive mounted and read-writable from linux, the share is visible from my Windows8(64Bit) desktop without username or password, but nothing I have on the network including my W7(64Bit) can get read/write access to the share.

getfacl /media/USBDRIVE/testFileMadeAtCommantLine.txt

# file: testFileMadeAtCommantLine.txt

# group: root

I have been through my system logs and I have not seen anything that corresponds with the permissions messages I get when I try to add or delete a file to the share.

Solution

The force user setting doesn't mean you don't have to supply a password. From smb.conf:

This user name only gets used once a connection is established. Thus clients still need to connect as a valid user and supply a valid password. Once connected, all file operations will be performed as the "forced user", no matter what username the client connected as. This can be very useful.

Specify guest account value and give this user rwx permissions.

Also you have read only = yes and read only = no specified on the same share? Fix that.

You can use testparm command to check smb.conf for errors and print out bare samba configuration.
