Hi,
I believe the DNS321 is running some version of Linux but admin doesn't
have access to the OS. I access them by samba although ftp also works.
Their target market is, of course, Windows.

There are thousands of files on there that do show permissions and
ownership:

fred@ragnok:~$ ls -l /mnt/dns321/pdf_1/W5300.pdf
-rw-r--r-- 1 502 502 1740845 Sep 25 2011 /mnt/dns321/pdf_1/W5300.pdf

There are 23 files in two directories that have the funky permissions I
showed earlier and can't be read. I don't know how they came by the
funky permissions as I originally just mv or cp them to the NAS box.

Best regards,
Fred
