Using your LinkStation

Notes:

•When using two-byte characters (such as Japanese), make folder or file names with 80 characters or less. You may not be able to copy a folder or a file whose name length is more than 80 characters.

•You cannot set hidden or read-only attributes to sub-folders or files on the LinkStation.

•If non-Roman alphabetical folder names or workgroup names do not display properly, rename the folder or workgroup with Roman alphabetical characters.

•Please don’t use any of the following words as the name of a shared folder. These words are reserved for internal use by the LinkStation:

info, spool, usbdisk1, usbdisk2, usbdisk3, usbdisk4, lost+found, global, printers, homes, lp, auth, test, ram, disk1, disk2, disk3, disk4, array1, array2, msdfs_root, mt-daapd

•The following characters are handled differently by Mac OS X andWindows. Avoid using these characters when sharing data between Mac OS X and Windows:

•The following characters are not displayed correctly byWindows, or by a Mac connected to the LinkStation via SMB.

Avoid their use in file names that will be used with the LinkStation.

•Never turn off the LinkStation or unplug its network cable while data is being written. Doing so may result in an incomplete file that cannot be opened or deleted. If this happens, restart the LinkStation, delete the file, then retry copying the file.

•Your OS may update the date and timestamp stored on the LinkStation’s hard drive, or on a USB drive connected to the LinkStation. This might result in inaccurate information for date-created or date-accessed data on the LinkStation.

•In the LinkStation’s configuration utility, or from a Mac OS X 10.6 or later, drive size is displayed in gigabytes, where 1 gigabyte = 1,000,000,000 bytes. This is also how drive capacity is expressed on your LinkStation’s packaging. However, if you check the drive size from an older Mac, or from a Windows computer, it may display the size of the drive in gibibytes, where 1 gibibyte = 1,073,741,824 bytes. Since a gibibyte is larger than a gigabyte, the displayed drive capacity will be a smaller number than the actual drive size.

Access Restrictions

There are several ways to restrict access to users of a LinkStation.

Access restrictions for locally registered users

The next page describes how to configure access restrictions for local users.

Access restrictions by using the Delegate Authority server feature

Follow the procedure on page 11 to configure.

Notes: • Permissions are assigned to shared folders. Child folders in a shared folder inherit their permissions from the parent folder. If a file or folder is moved into a new shared folder with different permissions from the folder it was originally in, it will now have the access restrictions from the new shared folder.

•When accessing the LinkStation fromWindows via SMB, changing permissions from the folder’s security tab in the properties screen of a folder is not supported. Access restrictions for shared folders on the LinkStation can only be configured from within the LinkStation’s configuration utility.

Access restrictions by using the Delegate Authority server feature

You may administer all user accounts and passwords centrally from a delegate server as described below. This procedure is intended for network administrators only.

Notes: • You can set access restrictions on shared folders.You cannot set different restrictions on folders in a shared folder. Child folders in a shared folder inherit their permissions from the parent folder.

•When accessing the LinkStation fromWindows via SMB, changing permissions from the folder’s security tab in the properties screen of a folder is not supported. Access restrictions for shared folders on the LinkStation can only be configured from within the LinkStation’s configuration utility.

There are restrictions when administrating through a delegate authority server:.

•To access the LinkStation, you must be logged intoWindows with the account registered to the authentication server.

•If you use the Delegate Authority option, you cannot connect as a guest user via AFP.

•If you use the Delegate Authority option, you cannot connect anonymously via FTP.

Notes:

Windows Vista and Windows Server 2003/Server 2008 users need to change the security settings to use the Delegate Authority to External SMB server feature to restrict access.

[Start] - [BUFFALO] - [File Sharing Security Level Change Tool] - [File Sharing Security Level Change Tool], and then select [Change Security level] to change the security settings (Select "Recover default security level" change it back to the previous setting).

Accessing the LinkStation with an Anonymous user:

To allow anonymous access to your FTP share, disable access restrictions on the FTP share. Configure your FTP client as follows:

• Host Name	IP address of the LinkStation
• Username	anonymous
• Password	any set of characters
• Port	21

Example ftp://192.168.11.150/

•To make your FTP share available from outside your network, you will need to configure your router and firewall. Consult your router’s documentation for information on how to allow FTP traffic.

•If the LinkStation joins a domain, anonymous users cannot access it.

•Folders created or copied via an AFP connection may not be deleted from the AFP connection. This is because an automatically generated ".AppleDouble" folder begins with a dot. To delete these files, use an SMB connection.

•Do not exceed 250 characters for a file/folder name including directory path when you are creating it by using an FTP connection. Otherwise, you cannot view or delete it in Explorer or other applications.

•To use jumbo frames (4102/7422/9694 bytes), your computer’s NICs and all switches, hubs, and routers on the transmission route need to support jumbo frames. If any device on the route doesn’t support jumbo frames, use standard transmission (1518 bytes) instead.

•If you are using jumbo frames and back up data from a LinkStation/TeraStation to another

LinkStation/TeraStation, set the Ethernet frame sizes of the LinkStations/TeraStations to the same settings (or the closest available). If the Ethernet frame sizes are significantly different, the backup job may fail. If you have problems with backup jobs, select the default frame size (1518 bytes).
