FTP User Authentication
FTP users can authenticate themselves when connecting to the FTP site or to use anonymous access (if allowed by the FTP site).
When authenticated using a user name and password, the connection is encrypted. Anonymous users authenticate using
anonymous as the user name and a valid email address as the password.
FTP Limitations
• The number of concurrent FTP sessions is limited to 800 sessions per NAS appliance.
• Idle FTP connections time out and close after 900 seconds (15 minutes).
• The FTP client does not follow symbolic links, NFS referrals, or SMB wide-links.
• FTP changes in directory structure (create new le, delete, rename) trigger SMB change notications.
• FTP access triggers le-access notication events (the File Access Notication feature).
• FTP presents the underlying le system as case sensitive.
• File names have the following limitations:
– Are case sensitive
– Cannot be longer than 255 characters
– Cannot contain any of the following characters:
* . and ..
* @Internal&Volume!%File
– Cannot have a sux of four, or multiple of three, characters between two ~ signs (for example, ~1234~ and ~123123~)

Using Symbolic Links
A symbolic link is a special type of le that contains a reference to another le or directory in the form of an absolute or relative path
and that aects path name resolution. Symbolic links operate transparently for most operations: programs that read or write to les
named by a symbolic link behave as if operating directly on the target le. The symbolic link contains a text string that is
automatically interpreted and followed by the operating system as a path to another le or directory.
Local le system symbolic links are available in NTFS starting with Windows Vista and Windows Server 2008, but the symbolic links
over SMB are available only with SMB2.
Limitations on Using Symbolic Links
When using symbolic links, note the following limitations:
• SMB1, FTP, and NFS do not support symbolic links.
