Mounted my USB stick (sitting at the Fritz!Box) to my Raspi

1. Plug the USB stick into the Fritz!Box 7362 SL. It is ready to use then.

2. Create a user in your Fritz!Box with only the permission to use NAS content.

3. Add your NAS content folder to the permissions for your new user.
4. Create a directory on your Raspberry # sudo mkdir /mnt/usb
5. Add an entry to your /etc/fstab # sudo vi /etc/fstab
//192.168.178.1/fritz.nas/SanDisk-CruzerBlade-01/FRITZ/mediabox /mnt/usb        cifs    defaults,username=piusb,password=***** 0       0

You'll have to use your plaintext password for your fstab. If you do not want to do this then use a credential file like credentials=/etc/samba/share.cred.

6. Reload your /etc/fstab # mount -a
