====== How to workaround the DFS samba bug on the DNS323 NAS ? ======

Firstly, here is a quick bug description: It's impossible to modify any existing files. The "Not a directory" or "No such file or directory" or "touch: setting times of..." errors occurs when trying to modify a file.

If your linux ''cifs'' or ''smbfs'' client support the ''nodfs'' flag (integrated in kernels > 2.6.27). You just have to add this option to the mount command. Example: <code>
mount -t cifs -o credentials=/home/kerphi/.smb-zekra-credentials,iocharset=utf8,file_mode=0777,dir_mode=0777,nodfs //zekra/Volume_1 /home/kerphi/zekra
</code>

If you cannot upgrade your kernel (like me because i'm following the debian releases), you have to follow this workaround:
  * Connect to the DNS323 using the web GUI and goto tools->system.
  * Save the configuration to your workstation (in "CONFIGURATION SETTINGS" section).
  * After saving edit the file and just under this line: <code>;[ global ]</code> add the following line:<code>
msdfs root = no
</code>
  * Then upload this file through the web interface, your NAS will reboot and you will be able to modify existing file again !
