Hi All, Google is killing me here! Scientific Linux 7.2, 64 bit $ rpm -qa samba samba-4.2.3-11.el7_2.x86_64 Is there some trick to mounting an NTFS USB flash drive and sharing it with Samba? I am trying to share an NTFS flash drive with samba. If the drive is not mounted, I can do what I want from Windows 7 and XP on the mount point. I have full access. But, when I mount the stick to the mount point and try to browse the mount with W7 or XP, I get "permission denied". Specifically, from the W7 machines samba log: ../source3/smbd/uid.c:384(change_to_user) Skipping user change - already user ../source3/smbd/open.c:881(open_file) Error opening file . (NT_STATUS_ACCESS_DENIED) (local_flags=0) (flags=0) I mount suchlike: # mount -t ntfs -rw -o users,exec,sync,uid=todd,gid=users,fmask=000,dmask=000 /dev/sdc1 /mnt/iso (I know I don't need the masks, but I left them there in case they were needed) After mounting: # ls -al /mnt/iso total 1193 drwxrwxrwx. 1 todd users 4096 Mar 3 23:30 . drwxr-xr-x. 13 todd users 4096 Mar 3 21:47 .. -rwxrwxrwx. 1 todd users 122 Apr 12 2011 autorun.inf drwxrwxrwx. 1 todd users 4096 Apr 12 2011 boot -rwxrwxrwx. 1 todd users 383786 Apr 12 2011 bootmgr -rwxrwxrwx. 1 todd users 669568 Apr 12 2011 bootmgr.efi drwxrwxrwx. 1 todd users 0 Apr 12 2011 efi -rwxrwxrwx. 1 todd users 106768 Apr 12 2011 setup.exe drwxrwxrwx. 1 todd users 40960 Apr 12 2011 sources drwxrwxrwx. 1 todd users 0 Apr 12 2011 support drwxrwxrwx. 1 todd users 0 Apr 12 2011 upgrade My smb.conf: [iso] comment = mnt on rn1 -- Mount as M: path = /mnt/iso valid users = @users write list = @users force group = users force user = todd oplocks = no level2 oplocks = no strict locking = no blocking locks = no force create mode = 0000 create mode = 0777 force directory mode = 0000 directory mode = 0777 map system = yes map hidden = yes writable = yes Trying simpler: [iso] comment = mnt on rn1 -- Mount as M: path = /mnt/iso force group = users force user = todd Doesn't work either What am I doing wrong?
